Correcting CIV-Based Virial Black Hole Masses
Liam Coatman, Paul C. Hewett, Manda Banerji +3
The CIV broad emission line is visible in optical spectra to redshifts exceeding z~5. CIV has long been known to exhibit significant displacements to the blue and these `blueshifts…
Cosmology with AGN dust time lags -- Simulating the new VEILS survey
S. F. Hönig, D. Watson, M. Kishimoto +9
The time lag between optical and near-infrared continuum emission in active galactic nuclei (AGN) shows a tight correlation with luminosity and has been proposed as a standardisabl…
The SCUBA-2 Cosmology Legacy Survey: 850um maps, catalogues and number counts
J. E. Geach, J. S. Dunlop, M. Halpern +66
We present a catalogue of nearly 3,000 submillimetre sources detected at 850um over ~5 square degrees surveyed as part of the James Clerk Maxwell Telescope (JCMT) SCUBA-2 Cosmology…
VDES J2325-5229 a z=2.7 gravitationally lensed quasar discovered using morphology independent supervised machine learning
Fernanda Ostrovski, Richard G. McMahon, Andrew J. Connolly +56
We present the discovery and preliminary characterization of a gravitationally lensed quasar with a source redshift and image separation of lensed by a foregrou…
Discovery of a z=0.65 Post-Starburst BAL Quasar in the DES Supernova Fields
Dale Mudd, Paul Martini, Suk Sien Tie +55
We present the discovery of a z=0.65 low-ionization broad absorption line (LoBAL) quasar in a post-starburst galaxy in data from the Dark Energy Survey (DES) and spectroscopy from…
CIV Emission Line Properties and Systematic Trends in Quasar Black Hole Mass Estimates
Liam Coatman, Paul C. Hewett, Manda Banerji +1
Black-hole masses are crucial to understanding the physics of the connection between quasars and their host galaxies and measuring cosmic black hole-growth. At high redshift, z > 2…
The Evolution of Active Galactic Nuclei in Clusters of Galaxies from the Dark Energy Survey
E. Bufanda, D. Hollowood, T. E. Jeltema +53
The correlation between active galactic nuclei (AGN) and environment provides important clues to AGN fueling and the relationship of black hole growth to galaxy evolution. In this…
Heavily Reddened z~2 Type 1 Quasars II: H-alpha Star Formation Constraints from SINFONI IFU Observations
Susannah Alaghband-Zadeh, Manda Banerji, Paul C. Hewett +1
We use near infrared integral field unit (IFU) spectroscopy to search for H emission associated with star formation in a sample of 28 heavily reddened (0.5-1.9), h…
A Dark Energy Camera Search for an Optical Counterpart to the First Advanced LIGO Gravitational Wave Event GW150914
M. Soares-Santos, R. Kessler, E. Berger +112
We report initial results of a deep search for an optical counterpart to the gravitational wave event GW150914, the first trigger from the Advanced LIGO gravitational wave detector…
Comparing Dark Energy Survey and HST-CLASH observations of the galaxy cluster RXC J2248.7-4431: implications for stellar mass versus dark matter
A. Palmese, O. Lahav, M. Banerji +65
We derive the stellar mass fraction in the galaxy cluster RXC J2248.7-4431 observed with the Dark Energy Survey (DES) during the Science Verification period. We compare the stellar…
The Dark Energy Survey: more than dark energy - an overview
Dark Energy Survey Collaboration, T. Abbott, F. B. Abdalla +138
This overview article describes the legacy prospect and discovery potential of the Dark Energy Survey (DES) beyond cosmological studies, illustrating it with examples from the DES…
