The Extreme Hosts of Extreme Supernovae
James D. Neill, Mark Sullivan, Avishay Gal-Yam +22
We use GALEX ultraviolet (UV) and optical integrated photometry of the hosts of seventeen luminous supernovae (LSNe, having peak M_V < -21) and compare them to a sample of 26,000 g…
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…
PTF10nvg: An Outbursting Class I Protostar in the Pelican/North American Nebula
Kevin R. Covey, Lynne A. Hillenbrand, Adam A. Miller +28
During a synoptic survey of the North American Nebula region, the Palomar Transient Factory (PTF) detected an optical outburst (dubbed PTF10nvg) associated with the previously unst…
Evidence for an FU Orionis-like Outburst from a Classical T Tauri Star
Adam A. Miller, Lynne A. Hillenbrand, Kevin R. Covey +26
We present pre- and post-outburst observations of the new FU Orionis-like young stellar object PTF 10qpf (also known as LkHa 188-G4 and HBC 722). Prior to this outburst, LkHa 188-G…
Hubble Space Telescope Studies of Nearby Type Ia Supernovae: The Mean Maximum Light Ultraviolet Spectrum and its Dispersion
Jeff Cooke, Richard S. Ellis, Mark Sullivan +11
We present the first results of an ongoing campaign using the STIS spectrograph on-board the Hubble Space Telescope (HST) whose primary goal is the study of near ultraviolet (UV) s…
A sub-Saturn Mass Planet, MOA-2009-BLG-319Lb
N. Miyake, T. Sumi, Subo Dong +119
We report the gravitational microlensing discovery of a sub-Saturn mass planet, MOA-2009-BLG-319Lb, orbiting a K or M-dwarf star in the inner Galactic disk or Galactic bulge. The h…
