The Sloan Digital Sky Survey Monitor Telescope Pipeline
D. L. Tucker, S. Kent, M. W. Richmond +31
The photometric calibration of the Sloan Digital Sky Survey (SDSS) is a multi-step process which involves data from three different telescopes: the 1.0-m telescope at the US Naval…
Cosmological Constraints from the SDSS Luminous Red Galaxies
M Tegmark, D Eisenstein, M Strauss +64
We measure the large-scale real-space power spectrum P(k) using luminous red galaxies (LRGs) in the Sloan Digital Sky Survey (SDSS) and use this measurement to sharpen constraints…
Nearby Supernova Factory Observations of SN 2005gj: Another Type Ia Supernova in a Massive Circumstellar Envelope
The Nearby Supernova Factory Collaboration, G. Aldering, P. Antilogus +24
We report Nearby Supernova Factory observations of SN 2005gj, the second confirmed case of a "hybrid" Type Ia/IIn supernova. Our early-phase photometry of SN 2005gj shows that the…
Spectroscopic Observations and Analysis of the Unusual Type Ia SN 1999ac
The Supernova Cosmology Project, :, G. Garavini +55
We present optical spectra of the peculiar Type Ia supernova (SN Ia) 1999ac. The data extend from -15 to +42 days with respect to B-band maximum and reveal an event that is unusual…
Spectroscopic Observations and Analysis of the Peculiar SN 1999aa
G. Garavini, G. Folatelli, A. Goobar +55
We present an extensive new time-series of spectroscopic data of the peculiar SN 1999aa in NGC 2595. Our data set includes 25 optical spectra between -11 and +58 days with respect…
Merging Galaxies in the SDSS EDR
S. S. Allam, D. L. Tucker, J. A. Smith +5
We present a new catalog of merging galaxies obtained through an automated systematic search routine. The 1479 new pairs of merging galaxies were found in approximately 462 sq deg…
