The hydrogen-poor superluminous supernova iPTF13ajg and its host galaxy in absorption and emission
Paul M. Vreeswijk, Sandra Savaglio, Avishay Gal-Yam +24
We present imaging and spectroscopy of a hydrogen-poor superluminous supernova (SLSN) discovered by the intermediate Palomar Transient Factory: iPTF13ajg. At a redshift of z=0.7403…
A Wolf-Rayet-like progenitor of supernova SN 2013cu from spectral observations of a wind
Avishay Gal-Yam, I. Arcavi, E. O. Ofek +17
The explosive fate of massive stripped Wolf-Rayet (W-R) stars is a key open question in stellar physics. An appealing option is that hydrogen-deficient W-R stars are the progenitor…
A Continuum of H- to He-Rich Tidal Disruption Candidates With a Preference for E+A Galaxies
Iair Arcavi, Avishay Gal-Yam, Mark Sullivan +23
We present the results of a Palomar Transient Factory (PTF) archival search for blue transients which lie in the magnitude range between "normal" core-collapse and superluminous su…
Interaction-powered supernovae: Rise-time vs. peak-luminosity correlation and the shock-breakout velocity
E. O. Ofek, I. Arcavi, D. Tal +16
Interaction of supernova (SN) ejecta with the optically thick circumstellar medium (CSM) of a progenitor star can result in a bright, long-lived shock breakout event. Candidates fo…
