NGC 2770 - a supernova Ib factory?

Christina C. Thoene, Michal J. Michalowski, Giorgos Leloudas +5

NGC 2770 has been the host of three supernovae of Type Ib during the last 10 years, SN 1999eh, SN 2007uy and SN 2008D. SN 2008D attracted special attention due to the serendipitous…

Photometry and spectroscopy of GRB 060526: A detailed study of the afterglow and host galaxy of a z=3.2 gamma-ray burst

C. C. Thöne, D. A. Kann, G. Jóhannesson +58

Aims: With this paper we want to investigate the highly variable afterglow light curve and environment of gamma-ray burst (GRB) 060526 at . Methods: We present one of the…

Early spectroscopic identification of SN 2008D

D. Malesani, J. P. U. Fynbo, J. Hjorth +27

SN 2008D was discovered while following up an unusually bright X-ray transient in the nearby spiral galaxy NGC 2770. We present early optical spectra (obtained 1.75 days after the…

A Search for Host Galaxies of 24 Gamma-Ray Bursts

J. -E. Ovaldsen, A. O. Jaunsen, J. P. U. Fynbo +6

We report the results from observations of 24 gamma ray burst (GRB) fields from 2005 and 2006 undertaken at the Danish 1.54m telescope at ESO/La Silla. Photometry and positions for…

HI column densities of z > 2 Swift gamma-ray bursts

P. Jakobsson, J. P. U. Fynbo, C. Ledoux +18

Context: Before the launch of the Swift satellite, the majority of the gamma-ray burst (GRB) afterglows for which Ly-alpha was redshifted into the observable spectrum showed eviden…

No supernovae associated with two long-duration gamma ray bursts

Johan P. U. Fynbo, Darach Watson, Christina C. Thoene +28

It is now accepted that long duration gamma-ray bursts (GRBs) are produced during the collapse of a massive star. The standard "collapsar" model predicts that a broad-lined and lum…
