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…
Circumstellar Material in Type Ia Supernovae via Sodium Absorption Features
Assaf Sternberg, Avishay Gal-Yam, Josh D. Simon +17
Type Ia supernovae are key tools for measuring distances on a cosmic scale. They are generally thought to be the thermonuclear explosion of an accreting white dwarf in a close bina…
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…
PTF1 J071912.13+485834.0: An outbursting AM CVn system discovered by a synoptic survey
David Levitan, Benjamin J. Fulton, Paul J. Groot +14
We present extensive photometric and spectroscopic observations of PTF1 J071912.13+485834.0, an outbursting AM CVn system discovered by the Palomar Transient Factory (PTF). AM CVn…
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…
