A dark energy camera search for missing supergiants in the LMC after the advanced LIGO gravitational-wave event GW150914
(2016) [Artigo de periódico]The collapse of a stellar core is expected to produce gravitational waves (GWs), neutrinos, and in most cases a luminous supernova. Sometimes, however, the optical event could be significantly less luminous than a supernova ... -
Eight new Milky Way companions discovered in first-year Dark Energy Survey data
(2015) [Artigo de periódico]We report the discovery of eight new Milky Way companions in ~1800 deg2 of optical imaging data collected during the first year of the Dark Energy Survey (DES). Each system is identified as a statistically significant ... -
Galaxy clustering, photometric redshifts and diagnosis of systematics in the DES Science Verification data
(2016) [Artigo de periódico]We study the clustering of galaxies detected at i < 22.5 in the Science Verification observations of the Dark Energy Survey (DES). Two-point correlation functions are measured using 2.3×106 galaxies over a contiguous 116 ... -
Mass and galaxy distributions of four massive galaxy clusters from Dark Energy Survey Science Verification data
(2015) [Artigo de periódico]We measure the weak lensing masses and galaxy distributions of four massive galaxy clusters observed during the Science Verification phase of the Dark Energy Survey (DES). This pathfinder study is meant to (1) validate the ... -
Photometric redshift analysis in the Dark Energy Survey science verification data
(2014) [Artigo de periódico]We present results from a study of the photometric redshift performance of the Dark Energy Survey (DES), using the early data from a Science Verification period of observations in late 2012 and early 2013 that provided ... -
Photometric redshifts and clustering of emission line galaxies selected jointly by DES and eBOSS
(2017) [Artigo de periódico]We present the results of the first observations of the emission line galaxies (ELG) of the extended Baryon Oscillation Spectroscopic Survey. From the total 9000 targets, 4600 have been selected from the Dark Energy Survey ... -
redMaGiC : selecting luminous red galaxies from the DES Science Verification data
(2016) [Artigo de periódico]We introduce redMaGiC, an automated algorithm for selecting luminous red galaxies (LRGs). The algorithm was specifically developed to minimize photometric redshift uncertainties in photometric large-scale structure studies. ... -
Redshift distributions of galaxies in the Dark Energy Survey Science Verification shear catalogue and implications for weak lensing
(2016) [Artigo de periódico]We present photometric redshift estimates for galaxies used in the weak lensing analysis of the Dark Energy Survey Science Verification (DES SV) data. Four model- or machine learning-based photometric redshift methods—ANNZ2, ... -
Search for gamma-ray emission from DES dwarf spheroidal galaxy candidates with Fermi-LAT data
(2015) [Artigo de periódico]Due to their proximity, high dark-matter (DM) content, and apparent absence of non-thermal processes, Milky Way dwarf spheroidal satellite galaxies (dSphs) are excellent targets for the indirect detection of DM. Recently, ... -
The Dark Energy Survey : more than dark energy – an overview
(2016) [Artigo de periódico]This overview paper describes the legacy prospect and discovery potential of the Dark Energy Survey (DES) beyond cosmological studies, illustrating it with examples from the DES early data. DES is using a wide-field camera ... -
The redMaPPer galaxy cluster catalog from des science verification data
(2016) [Artigo de periódico]We describe updates to the redMaPPer algorithm, a photometric red-sequence cluster finder specifically designed for large photometric surveys. The updated algorithm is applied to 150 deg2 of Science Verification (SV) data ...
