An Interaction of a Magellanic Leading Arm High Velocity Cloud with the Milky Way Disk
N. M. McClure-Griffiths, L. Staveley-Smith, F. J. Lockman +6
The Leading Arm of the Magellanic System is a tidally formed HI feature extending $\sim 60\arcdeg$ from the Magellanic Clouds ahead of their direction of motion. Using atomic hydro…
The Australia Telescope 20 GHz (AT20G) Survey: The Bright Source Sample
Marcella Massardi, Ronald D. Ekers, Tara Murphy +14
The Australia Telescope 20 GHz (AT20G) Survey is a blind survey of the whole Southern sky at 20 GHz (with follow-up observations at 4.8 and 8.6 GHz) carried out with the Australia…
The Molonglo Galactic Plane Survey (MGPS-2): Compact Source Catalogue
T. Murphy, T. Mauch, A. Green +4
We present the first data release from the second epoch Molonglo Galactic Plane Survey (MGPS-2). MGPS-2 was carried out with the Molonglo Observatory Synthesis Telescope at a frequ…
Spitzer IRAC observations of newly-discovered planetary nebulae from the Macquarie-AAO-Strasbourg H-alpha Planetary Nebula Project
Martin Cohen, Quentin A. Parker, Anne J. Green +10
We compare H-alpha, radio continuum, and Spitzer Space Telescope (SST) images of 58 planetary nebulae (PNe) recently discovered by the Macquarie-AAO-Strasbo- urg H-alpha PN Project…
CRATES: An All-Sky Survey of Flat-Spectrum Radio Sources
Stephen E. Healey, Roger W. Romani, Gregory B. Taylor +5
We have assembled an 8.4 GHz survey of bright, flat-spectrum (alpha > -0.5) radio sources with nearly uniform extragalactic (|b|>10 deg) coverage for sources brighter than S_{4.8 G…
Properties of Luminous Red Galaxies in the Sloan Digital Sky Survey
T. Barber, A. Meiksin, T. Murphy
We perform population synthesis modelling of a magnitude-limited sample of 4391 Luminous Red Galaxies selected from the Sloan Digital Sky Survey Data Release 4 (SDSS DR4). We fit m…
The properties of extragalactic radio sources selected at 20 GHz
Elaine M. Sadler, Roberto Ricci, Ronald D. Ekers +12
We present some first results on the variability, polarization and general properties of radio sources selected in a blind survey at 20 GHz, the highest frequency at which a sensit…
A library of high resolution Kurucz spectra in the wavelength range 3000 - 10000 AA
Tara Murphy, Avery Meiksin
We present a library of 6410 synthetic spectra with resolution Lambda/dLambda = 250,000 based on the revised Kurucz 1993 model atmospheres. The library covers the wavelength range…
Abell 1451 and 1RXS J131423.6-251521: a multi-wavelength study of two dynamically perturbed clusters of galaxies
I. Valtchanov, T. Murphy, M. Pierre +2
We present results from optical, X-ray and radio observations of two X-ray bright (L_X ~ 10^{45} erg/s) galaxy clusters. A1451 is at redshift z=0.1989 and has line-of-sight velocit…
Radio sources in the 2dF Galaxy Redshift Survey - II. Local radio luminosity functions for AGN and star-forming galaxies at 1.4 GHz
Elaine M. Sadler, Carole A. Jackson, Russell D. Cannon +25
We have cross-matched the 1.4 GHz NRAO VLA Sky Survey (NVSS) with the first 210 fields observed in the 2dF Galaxy Redshift Survey (2dFGRS), covering an effective area of 325 square…
Radio Sources in the 2dF Galaxy Redshift Survey. I. Radio Source Populations
Elaine M. Sadler, V. J. McIntyre, C. A. Jackson +1
We present the first results from a study of the radio continuum properties of galaxies in the 2dF Galaxy Redshift Survey, based on thirty 2dF fields covering a total area of about…
