Astropy: A Community Python Package for Astronomy
The Astropy Collaboration, Thomas P. Robitaille, Erik J. Tollerud +42
We present the first public version (v0.2) of the open-source and community-developed Python package, Astropy. This package provides core astronomy-related functionality to the com…
The Herschel-SPIRE Legacy Survey (HSLS): the scientific goals of a shallow and wide submillimeter imaging survey with SPIRE
Asantha Cooray, Steve Eales, Scott Chapman +247
A large sub-mm survey with Herschel will enable many exciting science opportunities, especially in an era of wide-field optical and radio surveys and high resolution cosmic microwa…
The Most Slowly Declining Type Ia Supernova 2001ay
Kevin Krisciunas, Weidong Li, Thomas Matheson +28
We present optical and near-infrared photometry, as well as ground-based optical spectra and Hubble Space Telescope ultraviolet spectra, of the Type Ia supernova (SN) 2001ay. At ma…
Principal components of dark energy with SNLS supernovae: the effects of systematic errors
Eduardo J. Ruiz, Daniel L. Shafer, Dragan Huterer +1
We study the effects of current systematic errors in Type Ia supernova (SN Ia) measurements on dark energy (DE) constraints using current data from the Supernova Legacy Survey (SNL…
Nonlinear Decline-Rate Dependence and Intrinsic Variation of Type Ia Supernova Luminosities
Lifan Wang, Mark Strovink, Alexander Conley +4
Published B and V fluxes from nearby Type Ia supernovae are fitted to light-curve templates with 4-6 adjustable parameters. Separately, B magnitudes from the same sample are fitted…
