The STRong lensing Insights into the Dark Energy Survey (STRIDES) 2016 follow-up campaign. II. New quasar lenses from double component fitting
T. Anguita, P. L. Schechter, N. Kuropatkin +56
We report upon the follow up of 34 candidate lensed quasars found in the Dark Energy Survey using NTT-EFOSC, Magellan-IMACS, KECK-ESI and SOAR-SAMI. These candidates were selected…
Chemical Abundance Evidence of Enduring High Star Formation Rates in an Early Type Galaxy: High [Ca/Fe] in NGC 5128 Globular Clusters
J. E. Colucci, M. F. Duran, R. A. Bernstein +1
We present [Fe/H], ages, and Ca abundances for an initial sample of 10 globular clusters in NGC 5128 obtained from high resolution, high signal-to-noise ratio echelle spectra of th…
Globular Cluster Abundances from High-Resolution, Integrated-Light Spectroscopy. IV. The Large Magellanic Cloud: , Fe-peak, Light, and Heavy Elements
J. E. Colucci, R. A. Bernstein, S. A. Cameron +1
We present detailed chemical abundances in 8 clusters in the Large Magellanic Cloud (LMC). We measure abundances of 22 elements for clusters spanning a range in age of 0.05 to 12 G…
The Keck+Magellan Survey for Lyman Limit Absorption II: A Case Study on Metallicity Variations
Gabriel E. Prochter, J. Xavier Prochaska, John M. O'Meara +2
We present an absorption line analysis of the Lyman limit system (LLS) at z=3.55 in our Magellan/MIKE spectrum of PKS2000-330. Our analysis of the Lyman limit and full HI Lyman ser…
The Formation of Dust Lanes: Implications for Galaxy Evolution
Julianne J. Dalcanton, Peter Yoachim, Rebecca A. Bernstein
We find that disk galaxies show a sharp, mass-dependent transition in the structure of their dusty ISM. Dust lanes are a generic feature of massive disks with V_rot>120km/s, but ar…
The First Detections of the Extragalactic Background Light at 3000, 5500, and 8000A (II): Measurement of Foreground Zodiacal Light
R. A. Bernstein, W. L. Freedman, B. F. Madore
We present a measurement of the absolute surface brightness of the zodiacal light (3900-5100A) toward a fixed extragalactic target at high ecliptic latitude based on moderate resol…
