    NONLINEARITY OF THE TULLY-FISHER RELATION

    No full text
    A systematic variation of the dark matter abundance in spiral galaxies, previously reported (Persic & Salucci), accounts for the observed non-linearity of the Tully-Fisher relation. Increasing proportions of dark mass at low luminosities, as revealed by optical rotation curves, make faint galaxies shift to higher rotation velocities for a given luminosity, thus inducing a curvature in the velocity-luminosity correlation

    The hierarchical build-up of the Tully-Fisher relation

    No full text
    We use the semi-analytic model GalICS to predict the Tully-Fisher relation in the B, I and for the first time, in the K band, and its evolution with redshift, up to z~1. We refined the determination of the disk galaxies rotation velocity, with a dynamical recipe for the rotation curve, rather than a simple conversion from the total mass to maximum velocity. The new recipe takes into account the disk shape factor, and the angular momentum transfer occurring during secular evolution leading to the formation of bulges. This produces model rotation velocities that are lower by ~20-25% for the majority of the spirals. We implemented stellar population models with a complete treatment of the TP-AGB, which leads to a revision of the mass-to-light ratio in the near-IR. I/K band luminosities increase by ~0.3/0.5 mags at redshift z=0 and by ~0.5/1 mags at z=3. With these two new recipes in place, the comparison between the predicted Tully-Fisher relation with a series of datasets in the optical and near-IR, at redshifts between 0 and 1, is used as a diagnostics of the assembly and evolution of spiral galaxies in the model.

    Pre-clearing vegetation of the coastal lowlands of the Wet Tropics Bioregion, North Queensland

    A pre-clearing vegetation map and digital coverage at approximately 1:50 000 scale for the coastal lowlands (up to about 200 m elevation) of the Wet Tropics Bioregion, North Queensland is presented. The study area covers about 508 000 ha from Cooktown, 420 km south almost to Townsville (latitude 15° 30’–18° 20’ longitude 144° 50’–146° 40’). Data sources included historical aerial photography, early surveyors’ plans, explorers’ journals, previous vegetation maps, and maps of soils and geology. The pre-clearing mapping was built around the remnant vegetation mapping of Stanton & Stanton (2005), and the vegetation classification of this latter work was adopted. Vegetation units were further classified into regional ecosystems compatible with the standard State-wide system used by Queensland government. The digital coverage is part of the current Queensland Herbarium regional ecosystem coverage (Queensland Herbarium and Wet Tropics Management Authority 2005). Coloured maps (1:100 000 scale) of the pre-clearing vegetation of the Herbert, Tully, Innisfail and Macalister/Daintree subregions are on an accompanying CD-ROM. An evaluation of vegetation loss through clearing on the coastal lowlands of the Wet Tropics revealed several nearextinct vegetation communities and regional ecosystems, and many others that are drastically reduced in area. Even ecosystems occurring on poorly drained lands have suffered a surprisingly high level of loss due to the effectiveness of drainage operations. Grassland ecosystems were found to be widespread on the Herbert and Tully floodplains, but are now close to extinction. The lowlands vegetation of the Wet Tropics that remains today continues to be fragmented and degraded despite the introduction of State-wide broad-scale tree-clearing laws in 1999, and the cessation of broadscale tree-clearing in December 2006

    Wonder E. P.

    Research Background The recent development of the Digital Analogue Workstation has enabled the development of computer–based plugins that emulate the “warmth” and “colour” renowned with the use of vintage audio technology. In the past artists who produce organic folk music have preferred mixers to use vintage analogue audio equipment on their final mixers to colour the sound. Tully John & Liza Jane’s latest release “Wonder Ep” was a practiced based study into the mixing of organic folk tunes completely within the confines of the computer. Within this study the use of computer- based analogue emulation plugins were used to imitate the ‘warmth’ usually generated from vintage analogue equipment. This process was tested by the artist’s critique of the mixes and signifies a successful use of digital technologies on an analogue sounding product. Research Contribution This study informs the broad scope of literature currently available on a mixing inside and outside of the computer, and signifies a step in the direction of defining mixing as a by product of the tacit skills of mixing engineers as compared to the use of certain technology. This research is a testament to the value of practice-based investigations into popular music and informs practitioners and pedagogical frameworks in Music technology and popular music education. Research Significance Tully John & Liza Jane have successfully launched their “Wonder” Ep to an audience of over 100 people at the “Dust Bowl’ in Currumbin. The E.P is available on many online platforms including ITunes, see reviews here: http://blankgc.com.au/tully-john-and-liza-jane/ “[The] new single, ‘Dust’, delivers a stellar introduction to their sound, and [the] debut EP [is] ready to launch at The Dust Temple on 17 December”No Full Tex

    The Tully-Fisher relations for Hickson compact group galaxies star

    International audienceWe used K-band photometry, maximum rotational velocities derived from Fabry-Perot data and H i observed and predicted masses to study, for the first time, the K band, stellar and baryonic Tully-Fisher relations for galaxies in Hickson compact groups. We compared these relations with the ones defined for galaxies in less dense environments from the Gassendi HAlpha survey of Spirals and from a sample of gas-rich galaxies. We find that most of the Hickson compact group galaxies lie on the K-band Tully-Fisher relation defined by field galaxies with a few low-mass outliers, namely HCG 49b and HCG 96c, which appear to have had strong recent burst of star formation. The stellar Tully-Fisher relation for compact group galaxies presents a similar dispersion to that of the K-band relation, and it has no significant outliers when a proper computation of the stellar mass is done for the strongly star-forming galaxies. The scatter in these relations can be reduced if the gaseous component is taken into account, i.e. if a baryonic Tully-Fisher relation is considered. In order to explain the positions of the galaxies off the K-band Tully-Fisher relation, we favour a scenario in which their luminosities are brightened due to strong star formation or AGN activity. We argue that strong bursts of star formation can affect the B- and K-band luminosities of HCG 49b and HCG 96c and in the case of the latter also AGN activity may affect the K-band magnitude considerably, without affecting their total masses
