Galaxy and mass assembly (GAMA) : AUTOZ spectral redshift measurements, confidence and errors
Get PDFThe Galaxy And Mass Assembly (GAMA) survey has obtained spectra of over 230 000 targets using the Anglo-Australian Telescope. To homogenize the redshift measurements and improve the reliability, a fully automatic redshift code was developed (AUTOZ). The measurements were made using a cross-correlation method for both the absorption-and the emission-line spectra. Large deviations in the high-pass-filtered spectra are partially clipped in order to be robust against uncorrected artefacts and to reduce the weight given to single-line matches. A single figure of merit (FOM) was developed that puts all template matches on to a similar confidence scale. The redshift confidence as a function of the FOM was fitted with a tanh function using a maximum likelihood method applied to repeat observations of targets. The method could be adapted to provide robust automatic redshifts for other large galaxy redshift surveys. For the GAMA survey, there was a substantial improvement in the reliability of assigned redshifts and in the lowering of redshift uncertainties with a median velocity uncertainty of 33 kms-1.Peer reviewe

Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

Amazing Space: Planetary Nebula NGC 2440 Lithograph
No full textThis lithograph contains a Hubble Space Telescope image that shows the colorful Planetary Nebula NGC 2440 with one of the hottest known white dwarfs at its center. The text briefly explains the process of stellar death of sun-like stars and those with a mass greater than eight times the Sun. The accompanying classroom activity is a curriculum support tool designed for use as an introductory inquiry activity. It can be incorporated into a unit that has a scientific inquiry and/or stellar evolution theme. During the classroom activity, In Search of... Stellar Death, students use the lithograph images and text to generate questions about the planetary nebula NGC 2440 and how stars end their lives. Students conduct research to answer their questions then compare the endpoints of different mass stars, providing supporting evidence from their research.
