The Signature of Large Scale Structures on the Very High Energy Gamma-Ray Sky

A. Cuoco, S. Hannestad, T. Haugbølle +3

If the diffuse extragalactic gamma ray emission traces the large scale structures of the universe, peculiar anisotropy patterns are expected in the gamma ray sky. In particular, be…

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…

Capturing the Fire: Flame Energetics and Neutronizaton for Type Ia Supernova Simulations

A. C. Calder, D. M. Townsley, I. R. Seitenzahl +6

We develop and calibrate a realistic model flame for hydrodynamical simulations of deflagrations in white dwarf (Type Ia) supernovae. Our flame model builds on the advection-diffus…

A general solution to the E-B mixing problem

Kendrick M. Smith, Matias Zaldarriaga

We derive a general ansatz for optimizing pseudo-C_l estimators used to measure CMB anisotropy power spectra, and apply it to the recently-proposed pure pseudo-C_l formalism, to ob…

Broad Absorption Line Variability in Repeat Quasar Observations from the Sloan Digital Sky Survey

Britt F. Lundgren, Brian C. Wilhite, Robert J. Brunner +5

We present a time-variability analysis of 29 broad absorption line quasars (BALQSOs) observed in two epochs by the Sloan Digital Sky Survey (SDSS). These spectra are selected from…
