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…
Supernova rates from the Southern inTermediate Redshift ESO Supernova Search (STRESS)
M. T. Botticella, M. Riello, E. Cappellaro +11
To measure the supernova (SN) rates at intermediate redshift we performed the Southern inTermediate Redshift ESO Supernova Search (STRESS). Unlike most of the current high redshift…
The early spectral evolution of SN 2004dt
G. Altavilla, M. Stehle, P. Ruiz-Lapuente +18
Aims. We study the optical spectroscopic properties of Type Ia Supernova (SN Ia) 2004dt, focusing our attention on the early epochs. Methods. Observation triggered soon after the S…
ESC observations of SN 2005cf. I. Photometric Evolution of a Normal Type Ia Supernova
A. Pastorello, S. Taubenberger, N. Elias-Rosa +20
We present early-time optical and near-infrared photometry of supernova (SN) 2005cf. The observations, spanning a period from about 12 days before to 3 months after maximum, have b…
ESC and KAIT Observations of the Transitional Type Ia SN 2004eo
A. Pastorello, P. A. Mazzali, G. Pignata +31
We present optical and infrared observations of the unusual Type Ia supernova (SN) 2004eo. The light curves and spectra closely resemble those of the prototypical SN 1992A, and the…
Observational Constraints on the Nature of the Dark Energy: First Cosmological Results from the ESSENCE Supernova Survey
W. M. Wood-Vasey, G. Miknaitis, C. W. Stubbs +34
We present constraints on the dark energy equation-of-state parameter, w=P/(rho c^2), using 60 Type Ia supernovae (SNe Ia) from the ESSENCE supernova survey. We derive a set of con…
