Luminous Type II supernovae for their low expansion velocities
Ó. Rodríguez, G. Pignata, J. P. Anderson +27
We present optical and near-IR data of three Type II supernovae (SNe II), SN 2008bm, SN 2009aj, and SN 2009au. These SNe display the following common characteristics: signs of earl…
The delay of shock breakout due to circumstellar material seen in most Type II Supernovae
F. Förster, T. J. Moriya, J. C. Maureira +35
Type II supernovae (SNe) originate from the explosion of hydrogen-rich supergiant massive stars. Their first electromagnetic signature is the shock breakout, a short-lived phenomen…
Asteroids in the High cadence Transient Survey
J. Peña, C. Fuentes, F. Förster +11
We report on the serendipitous observations of Solar System objects imaged during the High cadence Transient Survey (HiTS) 2014 observation campaign. Data from this high cadence, w…
SN 2011A: an low-luminosity interacting transient, with a double plateau and strong sodium absorption
T. de Jaeger, J. P. Anderson, G. Pignata +16
We present optical photometry and spectroscopy of the optical transient SN 2011A. Our data spans 140 days after discovery including photometry and 11 epochs of opt…
