Photometric characterization of the Dark Energy Camera
G. M. Bernstein, T. M. C. Abbott, R. Armstrong +9
We characterize the variation in photometric response of the Dark Energy Camera (DECam) across its 520~Mpix science array during 4 years of operation. These variations are measured…
How Many Kilonovae Can Be Found in Past, Present, and Future Survey Datasets?
D. Scolnic, R. Kessler, D. Brout +83
The discovery of a kilonova (KN) associated with the Advanced LIGO (aLIGO)/Virgo event GW170817 opens up new avenues of multi-messenger astrophysics. Here, using realistic simulati…
A Hybrid Algorithm for Period Analysis from Multi-band Data with Sparse and Irregular Sampling for Arbitrary Light Curve Shapes
Abhijit Saha, A. Katherina Vivas
Ongoing and future surveys with repeat imaging in multiple bands are producing (or will produce) time-spaced measurements of brightness, resulting in the identification of large nu…
The Carnegie Supernova Project I: Third Photometry Data Release of Low-Redshift Type Ia Supernovae and Other White Dwarf Explosions
Kevin Krisciunas, Carlos Contreras, Christopher R. Burns +27
We present final natural system optical (ugriBV) and near-infrared (YJH) photometry of 134 supernovae (SNe) with probable white dwarf progenitors that were observed in 2004-2009 as…
DES Science Portal: Creating Science-Ready Catalogs
Angelo Fausti Neto, Luiz da Costa, Aurelio Carnero Rosell +55
We present a novel approach for creating science-ready catalogs through a software infrastructure developed for the Dark Energy Survey (DES). We integrate the data products release…
Instrumental response model and detrending for the Dark Energy Camera
G. M. Bernstein, T. M. C. Abbott, S. Desai +11
We describe the model for the mapping from sky brightness to the digital output of the Dark Energy Camera, and the algorithms adopted by the Dark Energy Survey (DES) for inverting…
