High-Amplitude, Rapid Photometric Variation of the New Polar MASTER OT J132104.04+560957.8
Colin Littlefield, Peter Garnavich, Katrina Magno +4
We present photometric and spectroscopic observations of the cataclysmic variable MASTER OT J132104.04+560957.8 which strongly indicate that it is a polar with an orbital period of…
The Mid-Infrared and Optical Decay of SN 2011fe
Colin M. McClelland, Peter M. Garnavich, Peter A. Milne +2
We measure the decay rate of the mid-IR luminosity from type Ia supernova 2011fe between six months and one year after explosion using Spitzer/IRAC observations. The fading in the…
Discovery of a Wolf-Rayet Star Through Detection of its Photometric Variability
Colin Littlefield, Peter Garnavich, G. H. Howie Marion +4
We report the serendipitous discovery of a heavily reddened Wolf-Rayet star that we name WR142b. While photometrically monitoring a cataclysmic variable, we detected weak variabili…
The Subluminous Supernova 2007qd: A Missing Link in a Family of Low-Luminosity Type Ia Supernovae
Colin M. McClelland, Peter M. Garnavich, Lluís Galbany +12
We present multi-band photometry and multi-epoch spectroscopy of the peculiar Type Ia supernova (SN Ia) 2007qd, discovered by the SDSS-II Supernova Survey. It possesses physical pr…
Go Long, Go Deep: Finding Optical Jet Breaks for Swift-Era GRBs with the LBT
X. Dai, P. M. Garnavich, J. L. Prieto +20
Using the 8.4m Large Binocular Telescope, we observed six GRB afterglows from 2.8 hours to 30.8 days after the burst triggers to systematically probe the late time behaviors of aft…
