Five New Outbursting AM CVn Systems Discovered by the Palomar Transient Factory
David Levitan, Thomas Kupfer, Paul J. Groot +10
We present five new outbursting AM CVn systems and one candidate discovered as part of an ongoing search for such systems using the Palomar Transient Factory (PTF). This is the fir…
Supernova 2003ie Was Likely a Faint Type IIP Event
Iair Arcavi, Avishay Gal-Yam, Sergey G. Sergeev
We present new photometric observations of Supernova (SN) 2003ie starting one month before discovery, obtained serendipitously while observing its host galaxy. With only a weak upp…
Millions of Multiples: Detecting and Characterizing Close-Separation Binary Systems in Synoptic Sky Surveys
Emil Terziev, Nicholas M. Law, Iair Arcavi +15
The direct detection of binary systems in wide-field surveys is limited by the size of the stars' point-spread-functions (PSFs). A search for elongated objects can find closer comp…
The Flavours of SN II Light Curves
Iair Arcavi
We present R-Band light curves of Type II supernovae (SNe) from the Caltech Core Collapse Program (CCCP). With the exception of interacting (Type IIn) SNe and rare events with long…
An Early & Comprehensive Millimeter and Centimeter Wave and X-ray Study of Supernova 2011dh: A Non-Equipartition Blastwave Expanding into A Massive Stellar Wind
Assaf Horesh, Christopher Stockdale, Derek B. Fox +24
Only a handful of supernovae (SNe) have been studied in multi-wavelength from radio to X-rays, starting a few days after explosion. The early detection and classification of the ne…
Discovery and Early Multi-Wavelength Measurements of the Energetic Type Ic Supernova PTF12gzk: A Massive-Star Explosion in a Dwarf Host Galaxy
Sagi Ben-Ami, Avishay Gal-Yam, Alexei V. Filippenko +45
We present the discovery and extensive early-time observations of the Type Ic supernova (SN) PTF12gzk. Our finely sampled light curves show a rise of 0.8mag within 2.5hr. Power-law…
