Evidence Against a Redshift z>6 for the Galaxy STIS 123627+621755
Daniel Stern, Peter Eisenhardt, Hyron Spinrad +5
The identification of galaxies at extreme distances provides our most direct information on the earliest phases of galaxy formation. The distance implied by redshifts z > 5 makes t…
The Chandra Multi-wavelength Project (ChaMP): a serendipitous survey with Chandra archival data
B. J. Wilkes, P. Green, R. Brissenden +34
The launch of the Chandra X-ray Observatory in July 1999 opened a new era in X-ray astronomy. Its unprecedented, <0.5" spatial resolution and low background are providing views of…
UV Spectropolarimetry of Narrow-line Radio Galaxies
Makoto Kishimoto, Robert Antonucci, Andrea Cimatti +4
We present the results of UV spectropolarimetry (2000 - 3000A) and far-UV spectroscopy (1500 - 2000A) of two low-redshift narrow-line radio galaxies (NLRGs) taken with the Faint Ob…
Red Quasars and Quasar Evolution: the Case of BALQSO FIRST J155633.8+351758
Joan Najita, Arjun Dey, Michael Brotherton
We present the first near-IR spectroscopy of the z=1.5 radio-loud BALQSO FIRST J155633.8+351758. Both the Balmer decrement and the slope of the rest-frame UV-optical continuum inde…
An excess of submm sources near 4C41.17: a candidate proto-cluster at z=3.8?
Rob J. Ivison, James S. Dunlop, Ian Smail +3
Biased galaxy-formation theories predict that massive galaxies at high redshifts should act as signposts to high-density environments in the early Universe, which subsequently evol…
First Results from the Large Area Lyman Alpha Survey
James E. Rhoads, Sangeeta Malhotra, Arjun Dey +3
We report on a new survey for z=4.5 Lyman alpha sources, the Large Area Lyman Alpha (LALA) survey. Our survey achieves an unprecedented combination of volume and sensitivity by usi…
