The Gemini Cluster Astrophysics Spectroscopic Survey (GCLASS): The Role of Environment and Self-Regulation in Galaxy Evolution at z ~ 1
Adam Muzzin, Gillian Wilson, H. K. C. Yee +15
We evaluate the effects of environment and stellar mass on galaxy properties at 0.85 < z < 1.20 using a 3.6um-selected spectroscopic sample of 797 cluster and field galaxies drawn…
The Hubble Space Telescope Cluster Supernova Survey: VI. The Volumetric Type Ia Supernova Rate
K. Barbary, G. Aldering, R. Amanullah +40
We present a measurement of the volumetric Type Ia supernova (SN Ia) rate out to z ~ 1.6 from the Hubble Space Telescope Cluster Supernova Survey. In observations spanning 189 orbi…
A highly magnified supernova at z=1.703 behind the massive galaxy cluster Abell 1689
R. Amanullah, A. Goobar, B. Clément +17
Our ability to study the most remote supernova explosions, crucial for the understanding of the evolution of the high-redshift universe and its expansion rate, is limited by the li…
The Rise-Time of Normal and Subluminous Type Ia Supernovae
S. Gonzalez-Gaitan, A. Conley, F. B. Bianco +21
We calculate the average stretch-corrected rise-time of type Ia supernovae (SNe Ia) in the Supernova Legacy Survey. We use the aggregate lightcurves of spectroscopic and photometri…
The properties of the brightest Lyman alpha emitters at z~5.7
C. Lidman, M. Hayes, D. H. Jones +5
(Abridged) We use deep VLT optical and near-IR spectroscopy and deep Spitzer/IRAC imaging to examine the properties of two of the most luminous Lyman alpha emitters at z=5.7. The c…
Photometric selection of Type Ia supernovae in the Supernova Legacy Survey
G. Bazin, V. Ruhlmann-Kleider, N. Palanque-Delabrouille +23
We present a sample of 485 photometrically identified Type Ia supernova candidates mined from the first three years of data of the CFHT SuperNova Legacy Survey (SNLS). The images w…
