Discovery of 9,000 new RR Lyrae in the Southern Catalina Surveys
G. Torrealba, M. Catelan, A. J. Drake +8
We present the results of a deep, wide-area variability survey in the Southern hemisphere, the first of its kind. As part of the Catalina Sky Surveys, the Siding Spring Survey (SSS…
Damped and sub-damped Lyman-? absorbers in z > 4 QSOs
Rodney Guimaraes, Patrick Petitjean, Reinaldo Ramos De Carvalho +5
We present the results of a survey for damped (DLA, log N(H I) > 20.3) and sub-damped Lyman-? systems (19.5 < log N(H I) < 20.3) at z > 2.55 along the lines-of-sight to 77 quasars…
Virtual Astronomy, Information Technology, and the New Scientific Methodology
S. G. Djorgovski
All sciences, including astronomy, are now entering the era of information abundance. The exponentially increasing volume and complexity of modern data sets promises to transform t…
The Infrared Counterpart of the Microquasar GRS 1758-258
D. M. Rothstein, S. S. Eikenberry, S. Chatterjee +3
We present revised infrared (2.2 micron) astrometry of the field containing the Galactic microquasar GRS 1758-258, using observations at the Keck I 10-m telescope. We find three ca…
Palomar 13: An Unusual Stellar System in the Galactic Halo
Patrick Cote, S. G. Djorgovski, Georges Meylan +2
We have measured Keck/HIRES radial velocities for 30 candidate red giants in the direction of Palomar 13: an object traditionally cataloged as a compact, low-luminosity globular cl…
CO and Dust in PSS2322+1944 at a redshift of 4.12
P. Cox, A. Omont, S. G. Djorgovski +7
Using the IRAM interferometer we have detected J=4-3 and 5-4 CO line emission toward the radio quiet quasar PSS2322+1944. At a redshift of z_CO=4.1199 this is the fourth and strong…
