Variable Sodium Absorption in a Low-Extinction Type Ia Supernova

Joshua D. Simon, Avishay Gal-Yam, Orly Gnat +18

Recent observations have revealed that some Type Ia supernovae exhibit narrow, time-variable Na I D absorption features. The origin of the absorbing material is controversial, but…

Nebular Phase Observations of the Type Ib Supernova 2008D/X-ray Transient 080109: Side-Viewed Bipolar Explosion

Masaomi Tanaka, Masayuki Yamanaka, Keiichi Maeda +11

We present optical spectroscopic and photometric observations of supernova (SN) 2008D, associated with the luminous X-ray transient 080109, at >300 days after the explosion (nebula…

The redshift and afterglow of the extremely energetic gamma-ray burst GRB 080916C

J. Greiner, C. Clemens, T. Kruehler +22

The detection of GeV photons from gamma-ray bursts (GRBs) has important consequences for the interpretation and modelling of these most-energetic cosmological explosions. The full…

Dynamical constraints on the neutron star mass in EXO 0748-676

T. Muñoz-Darias, J. Casares, K. O'Brien +4

We present VLT intermediate resolution spectroscopy of UY Vol, the optical counterpart of the LMXB X-ray burster EXO 0748-676. By using Doppler tomography we detect narrow componen…

VLT/NACO near-infrared observations of the transient radio magnetar 1E 1547.0-5408

R. P. Mignani, N. Rea, V. Testa +9

Despite about a decade of observations, very little is known about the optical and infrared (IR) emission properties of the Soft Gamma-ray Repeaters (SGRs) and of the Anomalous X-r…
