Core-collapse supernovae in low-metallicity environments and future all-sky transient surveys
D. R. Young, S. J. Smartt, S. Mattila +5
Aims: Massive stars in low-metallicity environments may produce exotic explosions such as long-duration gamma-ray bursts and pair-instability supernovae when they die as core-colla…
AGB stars as tracers of metallicity and mean age across M33
M. -R. L. Cioni, M. Irwin, A. M. N. Ferguson +6
Wide-field JHKs near-infrared observations covering an area of 1.8x1.8 sq. deg. centred on M33 were obtained using WFCAM at UKIRT. These data show a large population of intermediat…
Multiwavelength analysis of the intriguing GRB 061126: the reverse shock scenario and magnetization
A. Gomboc, S. Kobayashi, C. Guidorzi +30
We present a detailed study of the prompt and afterglow emission from Swift GRB 061126 using BAT, XRT, UVOT data and multi-color optical imaging from ten ground-based telescopes. G…
GRB 070714B - Discovery of the Highest Spectroscopically Confirmed Short Burst Redshift
J. F. Graham, A. S. Fruchter, A. J. Levan +5
Gemini Nod & Shuffle spectroscopy on the host of the short GRB 070714B shows a single emission line at 7167 angstroms which, based on a grizJHK photometric redshift, we conclude is…
Andromeda XVII: A New Low Luminosity Satellite of M31
Mike Irwin, Annette Ferguson, Avon Huxor +3
We report the discovery of a new dwarf spheroidal galaxy near M31 based on INT/WFC imaging. The system, Andromeda XVII (And XVII), is located at a projected radius of ~44 kpc from…
Short gamma-ray bursts from SGR giant flares and neutron star mergers: two populations are better than one
Robert Chapman, Robert S. Priddey, Nial R. Tanvir
There is increasing evidence of a local population of short duration Gamma-ray Bursts (sGRB), but it remains to be seen whether this is a separate population to higher redshift bur…
