The Hubble Space Telescope Cluster Supernova Survey: V. Improving the Dark Energy Constraints Above z>1 and Building an Early-Type-Hosted Supernova Sample
N. Suzuki, D. Rubin, C. Lidman +62
We present ACS, NICMOS, and Keck AO-assisted photometry of 20 Type Ia supernovae SNe Ia from the HST Cluster Supernova Survey. The SNe Ia were discovered over the redshift interval…
The Hubble Space Telescope Cluster Supernova Survey: II. The Type Ia Supernova Rate in High-Redshift Galaxy Clusters
K. Barbary, G. Aldering, R. Amanullah +40
We report a measurement of the Type Ia supernova (SN Ia) rate in galaxy clusters at 0.9 < z < 1.45 from the Hubble Space Telescope (HST) Cluster Supernova Survey. This is the first…
The Rest-frame Optical Colors of 99,000 SDSS Galaxies
V. Smolcic, Z. Ivezic, M. Gacesa +17
We synthesize the rest-frame Stroemgren colors using SDSS spectra for 99,088 galaxies selected from Data Release 1. This narrow-band ~200 AA photometric system (uz, vz, bz, yz), fi…
The Milky Way Tomography with SDSS: I. Stellar Number Density Distribution
Mario Juric, Zeljko Ivezic, Alyson Brooks +23
Abridged: We estimate the distances to ~48 million stars detected by the Sloan Digital Sky Survey and map their 3D number density distribution in 100 < D < 20 kpc range over 6,500…
Spectroscopic Target Selection in the Sloan Digital Sky Survey: The Main Galaxy Sample
Michael A. Strauss, David H. Weinberg, Robert H. Lupton +1
We describe the algorithm that selects the main sample of galaxies for spectroscopy in the Sloan Digital Sky Survey from the photometric data obtained by the imaging survey. Galaxy…
Higher Order Moments of the Angular Distribution of Galaxies from Early SDSS Data
István Szapudi, Joshua A. Frieman, Roman Scoccimarro +13
We present initial results for counts in cells statistics of the angular distribution of galaxies in early data from the Sloan Digital Sky Survey (SDSS). We analyze a rectangular s…
