First results from the ATCA 18 GHz pilot survey
R. Ricci, E. M. Sadler, R. D. Ekers +7
As a pilot study for the first all-sky radio survey at short wavelengths, we have observed 1216 sq. deg. of the southern sky at 18GHz (16mm) using a novel wide-band (3.4GHz bandwid…
Tidal Remnants and Intergalactic HII Regions
T. Oosterloo, R. Morganti, E. M. Sadler +3
We report the discovery of two small intergalactic HII regions in the loose group of galaxies around the field elliptical NGC 1490. The HII regions are located at least 100 kpc fro…
The local black-hole mass function from 2dFGRS radio galaxies
Elaine M. Sadler
Radio emission from early-type (E and S0) galaxies usually signals the presence of a central supermassive black hole. If radio luminosity and black-hole mass are correlated, then w…
Radio sources in the 2dF Galaxy Redshift Survey: AGN, starburst galaxies and their cosmic evolution
Elaine M. Sadler, Carole A. Jackson, Russell D. Cannon
Radio continuum surveys can detect galaxies over a very wide range in redshift, making them powerful tools for studying the distant universe. Until recently, though, identifying th…
HI in elliptical galaxies
Elaine M. Sadler, Tom Oosterloo, Raffaella Morganti
Neutral hydrogen is an important component of the interstellar medium in elliptical galaxies as well as a potentially valuable mass tracer. Until recently, HI surveys of early-type…
HI gas disks in elliptical galaxies
E. M. Sadler, T. Oosterloo, R. Morganti
We discuss a class of low-luminosity E/S0 galaxies which have both HI disks and (in contrast to more luminous E/S0s with HI) ongoing star formation. We suggest that such objects ar…
