Simultaneous XMM-Newton and ESO VLT observations of SN 1995N: probing the wind/ejecta interaction

L. Zampieri, P. Mucciarelli, A. Pastorello +3

We present the results of the first {\it XMM-Newton} observation of the interacting type IIn supernova 1995N, performed in July 2003. We find that the 0.2--10.0 keV unabsorbed flux…

An Asymmetric, Energetic Type Ic Supernova Viewed Off-Axis, and a Link to Gamma-Ray Bursts

P. A. Mazzali, K. S. Kawabata, K. Maeda +13

Type Ic supernovae, the explosions following the core collapse of massive stars that have previously lost their hydrogen and helium envelopes, are particularly interesting because…

Spectroscopic and Photometric Observations of SN IIn 1995N

A. Pastorello, I. Aretxaga, L. Zampieri +2

We present the results of a long-term program of monitoring of the famous SN 1995N, observed both in photometry (UBVRIJHK bands) and optical spectroscopy. The observations span a p…

SN 1998A: Explosion of a Blue Supergiant

A. Pastorello, E. Baron, D. Branch +11

We present spectroscopic and photometric observations of the peculiar Type II supernova (SN) 1998A. The light curves and spectra closely resemble those of SN 1987A, suggesting that…

Spectroscopy of the type Ia supernova SN 2002er: days -11 to +215

Rubina Kotak, Peter Meikle, Giuliano Pignata +8

We present an extensive set of optical spectroscopy of the nearby type Ia supernova, SN 2002er, with 24 epochs spanning -11 to +34 days. Its spectral evolution is fairly typical of…

High-Velocity Features: a ubiquitous property of Type Ia SNe

P. A. Mazzali, S. Benetti, G. Altavilla +26

Evidence of high-velocity features such as those seen in the near-maximum spectra of some Type Ia Supernovae (eg SN 2000cx) has been searched for in the available SNIa spectra obse…
