Ultra-bright optical transients are linked with type Ic supernovae
A. Pastorello, S. J. Smartt, M. T. Botticella +41
Recent searches by unbiased, wide-field surveys have uncovered a group of extremely luminous optical transients. The initial discoveries of SN 2005ap by the Texas Supernova Search…
GALEX and Pan-STARRS1 Discovery of SN IIP 2010aq: The First Few Days After Shock Breakout in a Red Supergiant Star
S. Gezari, A. Rest, M. E. Huber +34
We present the early UV and optical light curve of Type IIP supernova (SN) 2010aq at z=0.0862, and compare it to analytical models for thermal emission following SN shock breakout…
SN 2009kf : a UV bright type IIP supernova discovered with Pan-STARRS 1 and GALEX
M. T. Botticella, C. Trundle, A. Pastorello +43
We present photometric and spectroscopic observations of a luminous type IIP Supernova 2009kf discovered by the Pan-STARRS 1 (PS1) survey and detected also by GALEX. The SN shows a…
8-13 micron spectroscopy of NGC 253: a spatially resolved starburst
C. C. Dudley, C. G. Wynn-Williams
NGC 253 is a nearby spiral galaxy that is currently undergoing a nuclear burst of star formation in a 100 pc diameter region. We present spatially resolved 8--13 micron low-resolut…
The Deep Silicate Absorption Feature in IRAS 08572+3915 and Other Infrared Galaxies
C. C. Dudley, C. G. Wynn-Williams
New mid-infrared (10 and 20 micron) spectro-photometry of the ultraluminous infrared galaxy IRAS 08572+3915 is presented. The 10 micron spectrum reveals a deep silicate absorption…
