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…
The Subluminous and Peculiar Type Ia Supernova PTF09dav
M. Sullivan, M. M. Kasliwal, P. E. Nugent +17
PTF09dav is a peculiar subluminous type Ia supernova (SN) discovered by the Palomar Transient Factory (PTF). Spectroscopically, it appears superficially similar to the class of sub…
Galaxy Zoo Supernovae
A. M. Smith, S. Lynn, M. Sullivan +21
This paper presents the first results from a new citizen science project: Galaxy Zoo Supernovae. This proof of concept project uses members of the public to identify supernova cand…
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…
The X-ray Spectra of the Luminous LMXBs in NGC 3379: Field and Globular Cluster Sources
N. J. Brassington, G. Fabbiano, S. Blake +10
From a deep multi-epoch Chandra observation of the elliptical galaxy NGC 3379 we report the spectral properties of eight luminous LMXBs (LX>1.2E38 erg/s). We also present a set of…
