Calcium-rich gap transients in the remote outskirts of galaxies
Mansi M. Kasliwal, S. R. Kulkarni, Avishay Gal-Yam +25
From the first two seasons of the Palomar Transient Factory, we identify three peculiar transients (PTF09dav, PTF10iuv, PTF11bij) with five distinguishing characteristics: peak lum…
SN2010jp (PTF10aaxi): A Jet-Driven Type II Supernova
Nathan Smith, S. Bradley Cenko, Nat Butler +18
We present photometry and spectroscopy of the peculiar TypeII supernova (SN) 2010jp, also named PTF10aaxi. The light curve exhibits a linear decline with a relatively low peak abso…
PTF10ops - a subluminous, normal-width lightcurve Type Ia supernova in the middle of nowhere
Kate Maguire, Mark Sullivan, Rollin C. Thomas +26
PTF10ops is a Type Ia supernova (SN Ia), whose lightcurve and spectral properties place it outside the current SN Ia subtype classifications. Its spectra display the characteristic…
PTF11eon/SN2011dh: Discovery of a Type IIb Supernova From a Compact Progenitor in the Nearby Galaxy M51
Iair Arcavi, Avishay Gal-Yam, Ofer Yaron +40
On May 31, 2011 UT a supernova (SN) exploded in the nearby galaxy M51 (the Whirlpool Galaxy). We discovered this event using small telescopes equipped with CCD cameras, as well as…
Real-Time Detection and Rapid Multiwavelength Follow-up Observations of a Highly Subluminous Type II-P Supernova from the Palomar Transient Factory Survey
Avishay Gal-Yam, Mansi M. Kasliwal, Iair Arcavi +29
The Palomar Transient Factory (PTF) is an optical wide-field variability survey carried out using a camera with a 7.8 square degree field of view mounted on the 48-in Oschin Schmid…
The Progenitor of Supernova 2011dh/PTF11eon in Messier 51
Schuyler D. Van Dyk, Weidong Li, S. Bradley Cenko +12
We have identified a luminous star at the position of supernova (SN) 2011dh/PTF11eon, in pre-SN archival, multi-band images of the nearby, nearly face-on galaxy Messier 51 (M51) ob…
