Galaxies And Dust At High Redshift (2007)
Richard Hunstead, Max Pettini, David King, Linda J. Smith
Much of our knowledge about the formation and evolution of high-redshift galaxies has come from studying the absorption signatures they impress on the spectra of background QSOs. The damped Lyman ff...
A search for distant radio galaxies from SUMSS and NVSS: II. Optical Spectroscopy (2005)
De Breuck, Carlos, Klamer, Ilana, Johnston, Helen, Hunstead, Richard, Bryant, Julia, Rocca-Volmerange, Brigitte, ...
This is the second in a series of papers presenting observations and results for a sample of 76 ultra-steep-spectrum (USS) radio sources in the southern hemisphere designed to find galaxies at high...
CO(1-0) & CO(5-4) observations of the most distant known radio galaxy at z=5.2 (2005)
Klamer, Ilana, Ekers, Ron, Sadler, Elaine, Weiss, Axel, Hunstead, Richard, De Breuck, Carlos
Using the Australia Telescope Compact Array we have detected CO(1-0) and CO(5-4) from TNJ0924-2201 at z=5.2, the most distant radio galaxy known to date. This is the second highest redshift detection...
Low and High Angular Momentum Accretion Flows in BHCs: Case Study of XTE J1550-564 (2001)
Soria, Roberto, Wu, Kinwah, Hannikainen, Diana, McCollough, Mike, Hunstead, Richard
The 1998 outburst of XTE J1550-564 started with a hard X-ray spike, rising in less than a day and declining after 3-4 days; at the same time, the soft X-ray flux was rising with a longer timescale (~...
Formation of optical lines in black-hole binaries (2001)
Wu, Kinwah, Soria, Roberto, Johnston, Helen, Hunstead, Richard
The HI Balmer emission lines of black-hole binaries show double-peaked profiles during the high-soft state and the quiescent state. In the high-soft state the profiles are asymmetric with a stronger...
Optical Spectroscopy of GRO J1655-40 (1999)
Soria, Roberto, Wu, Kinwah, Hunstead, Richard
We have obtained optical spectra of the soft X-ray transient GRO J1655-40 during different X-ray spectral states (quiescence, high-soft and hard outburst) between 1994 Aug and 1997 Jun....
Quenching of the radio jet during the X-ray high state of GX 339-4 (1999)
Fender, Robert, Corbel, Stephane, Tzioumis, Tasso, McIntyre, Vince, Campbell-Wilson, Duncan, Nowak, Mike, ...
We have observed the black hole candidate X-ray binary GX 339-4 at radio wavelengths before, during and after the 1998 high/soft X-ray state transition. We find that the radio emission from the...
