A Comparison of Photometric Redshift Techniques for Large Radio Surveys

Ray P. Norris, M. Salvato, G. Longo +14

Future radio surveys will generate catalogues of tens of millions of radio sources, for which redshift estimates will be essential to achieve many of the science goals. However, sp…

A deep Parkes HI survey of the Sculptor group and filament: HI mass function and environment

T. Westmeier, D. Obreschkow, M. Calabretta +8

We present the results of a deep survey of the nearby Sculptor group and the associated Sculptor filament taken with the Parkes 64-m radio telescope in the 21-cm emission line of n…

Connecting X-ray absorption and 21cm neutral hydrogen absorption in obscured radio AGN

V. A. Moss, J. R. Allison, E. M. Sadler +22

Many radio galaxies show the presence of dense and dusty gas near the active nucleus. This can be traced by both 21cm HI absorption and soft X-ray absorption, offering new insight…

Outbursts of the intermediate-mass black hole HLX-1: a wind instability scenario

Roberto Soria, Aina Musaeva, Kinwah Wu +5

We model the intermediate-mass black hole HLX-1, using the Hubble Space Telescope, XMM-Newton and Swift. We quantify the relative contributions of a bluer component, function of X-…

HI absorption in nearby compact radio galaxies

M. Glowacki, J. R. Allison, E. M. Sadler +6

HI absorption studies yield information on both AGN feeding and feedback processes. This AGN activity interacts with the neutral gas in compact radio sources, which are believed to…

HI study of the environment around ESO 243-49, the host galaxy of an intermediate mass black hole

A. Musaeva, B. S. Koribalski, S. A. Farrell +9

The lenticular galaxy ESO 243-49 hosts the ultraluminous X-ray source HLX-1, the best candidate intermediate mass black hole (IMBH) currently known. The environments of IMBHs remai…
