Colors of 2625 Quasars at 0<z<5 Measured in the Sloan Digital Sky Survey Photometric System

Gordon T. Richards, Xiaohui Fan, Donald P. Schneider +3

We present an empirical investigation of the colors of quasars in the Sloan Digital Sky Survey (SDSS) photometric system. The sample studied includes 2625 quasars with SDSS photome…

The First Hour of Extra-galactic Data of the Sloan Digital Sky Survey Spectroscopic Commissioning: The Coma Cluster

SDSS Collaboration, Francisco J. Castander, Robert C. Nichol +6

On 26 May 1999, one of the Sloan Digital Sky Survey (SDSS) fiber-fed spectrographs saw astronomical first light. This was followed by the first spectroscopic commissioning run duri…

A 421 d Activity Cycle in the BeX Recurrent Transient A0538-66 from MACHO monitoring

C. Alcock, R. A. Allsman, D. R. Alves +23

We present a ~ 5-yr optical light curve of the recurrent Be/X-ray transient A0538-66 obtained as a by-product of the MACHO Project. These data reveal both a long-term modulation at…

Optical Spectra of Type Ia Supernovae at z=0.46 and z=1.2

Alison L. Coil, Thomas Matheson, Alexei V. Filippenko +19

We present optical spectra, obtained with the Keck 10-m telescope, of two high-redshift type Ia supernovae (SNe Ia) discovered by the High-z Supernova Search Team: SN 1999ff at z=0…

The MACHO Project Hubble Space Telescope Follow-Up: Preliminary Results on the Location of the Large Magellanic Cloud Microlensing Source Stars

C. Alcock, R. A. Allsman, D. R. Alves +21

We attempt to determine whether the MACHO microlensing source stars are drawn from the average population of the LMC or from a population behind the LMC by examining the HST color-…
