A New Distance to The Antennae Galaxies (NGC 4038/39) Based on the Type Ia Supernova 2007sr
Francois Schweizer, Christopher R. Burns, Barry F. Madore +13
Traditionally, the distance to NGC 4038/39 has been derived from the systemic recession velocity, yielding about 20 Mpc for H_0 = 72 km/s/Mpc. Recently, this widely adopted distanc…
A Study of the Type Ia/IIn Supernova 2005gj from X-ray to the Infrared: Paper I
J. L. Prieto, P. M. Garnavich, M. M. Phillips +53
We present extensive ugrizYHJK photometry and optical spectroscopy of SN 2005gj obtained by the SDSS-II and CSP Supernova Projects, which give excellent coverage during the first 1…
The Peculiar SN 2005hk: Do Some Type Ia Supernovae Explode as Deflagrations?
M. M. Phillips, W. Li, J. A. Frieman +41
We present extensive u'g'r'i'BVRIYJHKs photometry and optical spectroscopy of SN 2005hk. These data reveal that SN 2005hk was nearly identical in its observed properties to SN 2002…
Theoretical Modeling of Weakly Lensed Polarized Radio Sources
Christopher R. Burns, Charles C. Dyer, Philipp P. Kronberg +1
In this paper we present the theoretical basis for the modeling of weakly gravitationally lensed extended sources that are polarized. This technique has been used in the past to co…
The DDO IVC Distance Project: Survey Description and the Distance to G139.6+47.6
Christopher R. Burns, Christopher Tycner, Megan McClure +4
We present a detailed analysis of the distance determination for one intermediate Velocity Cloud (IVC G139.6+47.6) from the ongoing DDO IVC Distance Project. Stars along the line o…
The DDO IVC Distance Project
Michael D. Gladders, Tracy E. Clarke, Christopher R. Burns +14
We present the first set of distance limits from the David Dunlap Observatory Intermediate Velocity Cloud (DDO IVC) distance project. Such distance measures are crucial to understa…
