Evolution of emission line properties and metallicities of star-forming galaxies up to z ~ 3
No full textUntil recently, obtaining rest-frame optical spectra of galaxies at z > 1 was a
time consuming and challenging observation due to the difficult nature of near-infrared
(near-IR) spectroscopy. However, with the advent of second generation
ground-based near-IR spectrographs (e.g. KMOS, MOSFIRE), and the new low
resolution near-IR grisms on the Hubble Space Telescope (HST), we have entered
a new era in the study of high redshift galaxies. This thesis explores the physical
properties of star-forming galaxies in the redshift range 1 < z < 3 by utilising a
custom reduction of the 3D-HST near-IR grism spectroscopic survey.
One of the most important observational constraints on the evolution of galaxies is
the mass-metallicity relation (MZR), which is sensitive to both the star-formation
history and various inflow/outflow processes. I use the 3D-HST spectra to
provide a new constraint on the MZR at 2:0 < z < 2:3, and moreover measure
the O/H abundance directly from the oxygen and hydrogen emission lines ([OII],
[OIII] and Hβ) as opposed to the more common method at high redshift of
inferring O/H from the N/H ratio (via [NII] and Hα). I show that the traditional
form of the MZR is recovered from the 3D-HST data, with metallicity increasing
with the stellar mass of a galaxy. However, the absolute metallicity values I
derive are inconsistent with previous N/H-based measurements of metallicity at
these redshifts. Moreover, I show that the 3D-HST data is inconsistent with the
`fundamental metallicity relation' (FMR), and that, contrary to previous claims,
this local Universe relation may not hold out to z & 2.
To investigate this metallicity discrepancy further, I measure the evolution of the
[OIII]/Hβ nebular emission line ratio in the 3D-HST spectra over the redshift
range 1:3 < z < 2:3. I compare this observed line ratio evolution with state-of-the-
art theoretical models which take into account the independent evolution
of the ionization parameter, electron density and metallicity of star-forming
regions with redshift. The homogeneous 3D-HST dataset allows me to perform
a consistent analysis of this evolution which takes into account line luminosity
selection effects. I show that, according to models, the observed [OIII]/Hβ
evolution cannot be accounted for by pure metallicity evolution. Instead I am
able to infer that the line ratio evolution is more consistent with, at the very
least, an evolution to stronger ionizing conditions at high redshift, and perhaps
even denser star-forming regions. I explore how this result can also explain the
observed discrepancy between high redshift metallicity measurements.
In light of this finding, I revisit the MZR at z >~ 2 and employ a purely theoretical
approach to inferring metallicities from nebular lines, which is able to account for
an evolution in ionization conditions. I then use a selection of galaxies from the
local Universe, which mimic the properties of high redshift galaxies, to derive a
more robust ionization sensitive, conversion, between N/H and O/H. With this
new conversion which I am able to bring the previous inconsistent metallicity
measurements at z >~ 2 back into agreement. Finally, I am able to show that, in
this new formalism, the metallicity evolution between z = 2 and z = 3 is perhaps
not as large as previously reported.
To conclude I discuss ongoing work as part of the KMOS Deep Survey (KDS)
being undertaken with the near near-IR Multi-Object Spectrograph KMOS on the
VLT. I describe the observations and data reduction that has been completed to
date and describe how this instrument will allow me to extend the work presented
in this thesis to z > 3. I also introduce FIGS, a new HST near-IR grism survey
seeking to spectroscopically identify galaxies at 5:5 < z < 8:5 and work I have
begun in exploring this dataset
Fibonacci s-Cullen and s-Woodall Numbers
No full textAbstract The m-th Cullen number C m is a number of the form m2 m + 1 and the m-th Woodall number W m has the form m2 m − 1. In 2003, Luca and Stȃnicȃ proved that the largest Fibonacci number in the Cullen sequence is F 4 = 3 and that F 1 = F 2 = 1 are the largest Fibonacci numbers in the Woodall sequence. Very recently, the second author proved that, for any given s > 1, the equation F n = ms m ± 1 has only finitely many solutions, and they are effectively computable. In this note, we shall provide the explicit form of the possible solutions
William Portus Cullen
No full textSir William Portus Cullen was born on 28 May 1855 at Mount Johnston, near Jamberoo, New South Wales, the son of John Cullen and his wife Rebecca nee Clinton. He was educated at Kiama Public School and the University of Sydney (BA 1st class Honours 1880, MA 1882, LLB 1885, LLD 1887). (1)<br /><br />Cullen was an award winning student. Moving to Sydney at age 20 allowed him to further his education. Encouraged by the Rev Charles Badham, Dean of the Faculty of Arts, he entered the University of Sydney aged 22. He was awarded the University Scholarship for 1877 (shared with SJ Wright), the Lithgow Scholarship for 1878, the Professor Smith's Prize in Chemistry and Experimental Physics in 1878, the Barker Scholarship for 1879 in Mathematics, and the Renwick Scholarship for 1879 in Natural Science. When he graduated in 1880 he achieved First Class Honours in Classics and Second Class Honours in Mathematics. (2) After completing his degree, he was a lecturer/coach in mathematics at St Andrew's College and at St Paul's College. Graduating as a Master of Arts in 1882, he was also an examiner for the Faculty of Arts from 1882/3 to 1883/4 and again in 1889/90. (3)<br /><br />Cullen was called to the New South Wales Bar on 30 April 1883. He practised primarily in Equity, out of Victoria Chambers, Phillip Street, Sydney (1885), Lyndhurst Chambers (1887-1889), Lyndon Chambers (1890-1893), Northfield Chambers (1894-1897) and 145 Phillip Street (1898-1910). He gained the degrees of Bachelor of Laws in 1885 and Doctor of Laws in 1887. After the High Court of Australia began in 1903, he was recognised as one of Australia's leading constitutional lawyers. He was appointed a King's Counsel in February 1905. (4)<br /><br />Cullen continued to be involved with the University of Sydney: in lecturing, administration and social clubs. He was Challis Lecturer in the Law of Real Property and Equity from 1 March 1890 to 1894. He also delivered a lecture for the University of Sydney Extension Board in 1892 and was an unofficial Member of the Board, definitely in 1893/94, and possibly in other years. (5) He was an Examiner for the Faculty of Law in 1902/03. Twice he was Acting Dean of the Faculty of Law while Professor Pitt Cobbett was on leave of absence. The first period was from 7 March to 20 August 1898 and the second from 6 March to 19 August 1905. (6)<br /><br />Elected a Fellow of the University Senate on 20 June 1896 for a seat vacated by Justice Charles James Manning due to ill health, Cullen served until November 1934. He represented the Senate as a Council member of the Women's College from at least 1897 to 1908 and he continued his association with the University Extension Board as a Senate representative from at least 1898 to 1908. From April 1908 to April 1911 he was Vice-Chancellor of the University, re-elected in 1909 and 1910. On 11 September 1914 he was elected Chancellor of the University following the death of Sir Normand MacLaurin, a position he held until November 1934. Although re-elected as Chancellor in April 1934, he did not seek re-election to the Senate when his term expired in November 1934 and therefore resigned as Chancellor. (7)<br /><br />Cullen was one of the vice-presidents of the Sydney University Union from 1885-1888. He was president of the Sydney University Law Society from 1908/9 to 1909/10. He was president of the Classical Association of New South Wales from 1910/11 to 1914/15. He was president of the University Club from 1909 to 1934. (8)<br /><br />On 20 June 1891 Cullen, like his brother Joseph Francis Cullen before him, entered the New South Wales Parliament as a Member of the Legislative Assembly. William was the third member for the multi-member seat of Camden. He represented the Free Trade Party. Defeated at the election of 17 July 1894 when single member seats were re-introduced, he was appointed on 8 August 1895 to the Legislative Council for life under the Constitution Act. His main activities in the Council were the drafting of bills and amendments and proposing legal reform. A strong supporter of Australian Federalism both in Parliament and at public meetings, Cullen was an adviser to Sir George Reid during the Premier's Conference at Melbourne from 29 January to 2 February 1899. Cullen resigned from Parliament on 25 January 1910. (9)<br /><br />On 28 January 1910 Cullen was appointed Chief Justice of the Supreme Court of New South Wales and, as such, Judge Commissary of the Vice-Admiralty Court. The British Colonial Courts of Admiralty Act 1890 abolished Courts of Vice-Admiralty as Imperial courts separate from a colony's civil court system. Instead it allowed for the creation of Courts of Admiralty integrated into the colony's existing Supreme Court. This Act took effect in New South Wales on 1 July 1911. Thus the Supreme Court of New South Wales acquired the powers of a 'Colonial Court of Admiralty' under the 1890 Act with the Chief Justice or his nominee in charge. On 1 July 1911 Cullen ceased to be Judge Commissary of the Vice-Admiralty Court and became a Judge in Admiralty of the Supreme Court. Granted six months leave of absence from the position of Chief Justice and Judge in Admiralty on 28 July 1924, Cullen retired due to ill health on 27 January 1925. (10)<br /><br />Created a Knight Bachelor on 24 February 1911 for his services as Lieutenant Governor and Chief Justice of New South Wales, he was made a Knight Commander of the Order of St Michael and St George on 14 June 1912. He was awarded an Honorary Doctor of Laws by the University of Adelaide in 1926. (11)<br /><br />Cullen was appointed Lieutenant Governor of New South Wales on 30 March 1910. He was acting Governor on six occasions: 26 April to 12 November 1911, 11 to 14 March 1913, 30 April 1917 to 18 February 1918, 14 September 1923 to 27 February 1924, 24 August 1928 to 2 February 1929 and 9 April to 28 May 1930. He resigned from the position in September 1930. (12)<br /><br />Both Cullen and his wife, Eliza Jane (Lily) nee White, were active in the community. They married on 17 December 1891 at Carrington, Port Stephens. As well as his involvement with University activities and clubs, he was president of the Boy Scouts' Association and Boy's Brigade, a trustee of the Public Library of New South Wales (1914-1935), and a director of Prince Alfred Hospital (1915-1935). Lily Cullen was president of the Sydney University Women's Society/Settlement from 1909 to 1913 and patroness of the Sydney University Women's Union from 1916/17. She was also a foundation vice-president of the New South Wales division of the Red Cross in 1914 and in 1916-17 president of the Australian Red Cross. She was president of the Victoria League and chief commissioner of the New South Wales Girl Guides' Association. (13) <br /><br />Cullen was a keen gardener with a deep interest in the preservation of Australian flora. A species of North Queensland eucalyptus, Eucalyptus cullenii (Cullen's ironbark), was named in his honour. (14)<br /><br />Sir William Portus Cullen died on 6 April 1935 at Leura, survived by his two sons and one of his two daughters. Lady Cullen died on 10 June 1931. (15) <br /><br />Endnotes<br />1.

Numerical modeling of groundwater-driven stream network evolution in low-relief areas
No full textFluvial channel networks are observed to grow in unchannelized areas of low relief despite the low potential energy for erosion in these areas of low slope. Under these low slope conditions significant channel growth only occurs when water is collected and flows as concentrated discharge in specific areas. Previous work examined how surface water routing out of closed depressions on the landscape could produce concentrated discharge to drive channel incision. We propose that water could be routed underground to feed growing channels and numerically model the contribution of groundwater contribution to stream development. Our results show that groundwater seepage steepens river long profiles, and moderate groundwater contributions (< 25% of total water) increase the rate of channel growth relative to cases with only surface water. Groundwater input also promotes branching near the groundwater seeps. These results indicate that we cannot disregard groundwater as a potentially significant contributor to stream evolution in low-relief areas. In particular, we suggest that groundwater seepage could have played a significant role in post-glacial stream development of the Central Lowlands of the United States.Submission published under a 24 month embargo labeled 'Closed Access', the embargo will last until 2021-08-01The student, Cecilia Cullen, accepted the attached license on 2019-07-12 at 10:06.The student, Cecilia Cullen, submitted this Thesis for approval on 2019-07-12 at 10:13.This Thesis was approved for publication on 2019-07-15 at 14:49.DSpace SAF Submission Ingestion Package generated from Vireo submission #14297 on 2019-11-26 at 14:04:11Made available in DSpace on 2019-11-26T20:59:48Z (GMT).

Evaluation of an Internet-Based, Psychosexual Intervention for Couples Following Treatment for Breast Cancer: A Phase 1 Trial
No full textDespite the well-established evidence that many breast cancer survivors encounter some degree of difficulty regarding their sexuality, support for women and couples experiencing sexual difficulties as a result of breast cancer is lacking. The purpose of this dissertation was to develop and evaluate an online psychosexual intervention for couples experiencing sexual difficulties following breast cancer. The feasibility, acceptability, and preliminary impact of the intervention were evaluated using a single-arm, mixed-methods design, with participants completing questionnaires concerning sexual functioning, marital quality, and psychological adjustment at baseline, post-treatment, and three-month follow-up, along with satisfaction surveys and post-treatment interviews Participants subjective experiences were triangulated with the quantitative data as a form of cross-verification, and to capture a more nuanced understanding of couples experiences with this intervention and its delivery, along with its benefits. A sample of 14 couples (N = 28) received a 6-session psychosexual intervention delivered via videoconferencing (eTherapy). The intervention was found to be feasible and acceptable, as demonstrated by high retention, treatment adherence, and satisfaction. There was also evidence to suggest that the intervention was effective at improving sexual functioning and satisfaction, although decreasing effect sizes at 3-month follow-up point towards a progressive loss of gains on a number of measures over time. The use of eTherapy was widely accepted by participants, who highlighted several advantages of this modality. Overall, the results support the effectiveness of this eTherapy psychosexual intervention for couples affected by breast cancer. Emerging considerations for researchers and clinicians involved in the evaluation and implementation of psychosexual interventions, as well as in the provision of eTherapy, are also introduced
