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 highly magnified supernova at z=1.703 behind the massive galaxy cluster Abell 1689
R. Amanullah, A. Goobar, B. Clément +17
Our ability to study the most remote supernova explosions, crucial for the understanding of the evolution of the high-redshift universe and its expansion rate, is limited by the li…
Core-Collapse Supernovae from the Palomar Transient Factory: Indications for a Different Population in Dwarf Galaxies
Iair Arcavi, Avishay Gal-Yam, Mansi M. Kasliwal +26
We use the first compilation of 72 core-collapse supernovae (SNe) from the Palomar Transient Factory (PTF) to study their observed subtype distribution in dwarf galaxies compared t…
Near-IR Search for Lensed Supernovae Behind Galaxy Clusters - II. First Detection and Future Prospects
A. Goobar, K. Paech, V. Stanishev +11
Powerful gravitational telescopes in the form of massive galaxy clusters can be used to enhance the light collecting power over a limited field of view by about an order of magnitu…
Tentative detection of the gravitational magnification of type Ia supernovae
Jakob Jonsson, Tomas Dahlen, Ariel Goobar +2
The flux from distant type Ia supernovae (SN) is likely to be amplified or de-amplified by gravitational lensing due to matter distributions along the line-of-sight. A gravitationa…
