Spectra of Hydrogen-Poor Superluminous Supernovae from the Palomar Transient Factory
Robert M. Quimby, Annalisa De Cia, Avishay Gal-Yam +20
Most Type I superluminous supernovae (SLSNe-I) reported to date have been identified by their high peak luminosities and spectra lacking obvious signs of hydrogen. We demonstrate t…
Type II supernova energetics and comparison of light curves to shock-cooling models
Adam Rubin, Avishay Gal-Yam, Annalisa De Cia +37
During the first few days after explosion, Type II supernovae (SNe) are dominated by relatively simple physics. Theoretical predictions regarding early-time SN light curves in the…
Rescuing the intracluster medium of NGC 5813
Noam Soker, Shlomi Hillel, Assaf Sternberg
We use recent X-ray observations of the intracluster medium (ICM) of the galaxy group NGC 5813 to confront theoretical studies of ICM thermal evolution with the newly derived ICM p…
Slow-Speed Supernovae from the Palomar Transient Factory: Two Channels
Christopher J. White, Mansi M. Kasliwal, Peter E. Nugent +20
Since the discovery of the unusual prototype SN 2002cx, the eponymous class of low-velocity, hydrogen-poor supernovae has grown to include at most another two dozen members identif…
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…
Multi-Epoch High-Spectral-Resolution Observations of Neutral Sodium in 14 Type Ia Supernovae
A. Sternberg, A. Gal Yam, J. D. Simon +16
One of the main questions concerning Type Ia supernovae is the nature of the binary companion of the exploding white dwarf. A major discriminant between different suggested models…
