The CHilean Automatic Supernova sEarch (CHASE)
G. Pignata, J. Maza, M. Hamuy +16
The CHASE project started in 2007 with the aim of providing young southern supernovae (SNe) to the Carnegie Supernova Project (CSP) and Millennium Center for Supernova Studies (MCS…
A New Distance to The Antennae Galaxies (NGC 4038/39) Based on the Type Ia Supernova 2007sr
Francois Schweizer, Christopher R. Burns, Barry F. Madore +13
Traditionally, the distance to NGC 4038/39 has been derived from the systemic recession velocity, yielding about 20 Mpc for H_0 = 72 km/s/Mpc. Recently, this widely adopted distanc…
Improved Cosmological Constraints from New, Old and Combined Supernova Datasets
M. Kowalski, D. Rubin, G. Aldering +67
We present a new compilation of Type Ia supernovae (SNe Ia), a new dataset of low-redshift nearby-Hubble-flow SNe and new analysis procedures to work with these heterogeneous compi…
The underluminous Type Ia Supernova 2005bl and the class of objects similar to SN 1991bg
S. Taubenberger, S. Hachinger, G. Pignata +24
Optical observations of the Type Ia supernova (SN Ia) 2005bl in NGC 4070, obtained from -6 to +66 d with respect to the B-band maximum, are presented. The photometric evolution is…
A Study of the Type Ia/IIn Supernova 2005gj from X-ray to the Infrared: Paper I
J. L. Prieto, P. M. Garnavich, M. M. Phillips +53
We present extensive ugrizYHJK photometry and optical spectroscopy of SN 2005gj obtained by the SDSS-II and CSP Supernova Projects, which give excellent coverage during the first 1…
Spectroscopic observations of eight supernovae at intermediate redshift
C. Balland, M. Mouchet, R. Amanullah +16
We present spectra of six Type Ia and two Type II supernovae obtained in June 2002 at the William Herschel Telescope during a search for Type Ia supernovae (SNIa) at intermediate r…
