Observation and Confirmation of Six Strong Lensing Systems in The Dark Energy Survey Science Verification Data
B. Nord, E. Buckley-Geer, H. Lin +89
We report the observation and confirmation of the first group- and cluster-scale strong gravitational lensing systems found in Dark Energy Survey (DES) data. Through visual inspect…
Galaxy structure from multiple tracers: I. A census of M87's globular cluster populations
L. J. Oldham, M. W. Auger
We present a new photometric catalogue of the rich globular cluster (GC) system around M87, the brightest cluster galaxy in Virgo. Using archival Next Generation Virgo cluster Surv…
Resolving Ionisation and Metallicity on Parsec Scales Across Mrk 71 with HST-WFC3
Bethan L. James, Matthew Auger, Alessandra Aloisi +2
Blue Compact Dwarf (BCD) Galaxies in the nearby Universe provide a means for studying feedback mechanisms and star-formation processes in low-metallicity environments in great deta…
Discovery of two gravitationally lensed quasars in the Dark Energy Survey
Adriano Agnello, Tommaso Treu, Fernanda Ostrovski +77
We present spectroscopic confirmation of two new lensed quasars via data obtained at the 6.5m Magellan/Baade Telescope. The lens candidates have been selected from the Dark Energy…
High resolution imaging and spectroscopy of the gravitational lens SDSSJ1206+4332: a natural coronagraph at and a standard ruler at
Adriano Agnello, Alessandro Sonnenfeld, Sherry H. Suyu +5
We present spectroscopy and laser guide star adaptive optics (LGSAO) images of the doubly imaged lensed quasar SDSS J1206+4332. We revise the deflector redshift proposed previously…
