Andrew Schechtman-Rook, Matthew A. Bershady
We probe the disk structure of the nearby, massive, edge-on spiral galaxy NGC 891 with sub-arcsecond resolution JHKs-band images covering ~+/-10 kpc in radius and +/-5 kpc in heigh…
ALFALFA Discovery of the Nearby Gas-Rich Dwarf Galaxy Leo~P. III. An Extremely Metal Deficient Galaxy
Evan D. Skillman, John J. Salzer, Danielle A. Berg +10
We present KPNO 4-m and LBT/MODS spectroscopic observations of an HII region in the nearby dwarf irregular galaxy Leo P discovered recently in the Arecibo ALFALFA survey. In both o…
Ca, Fe, and Mg Trends Among and Within Elliptical Galaxies
Guy Worthey, Briana A. Ingermann, Jedidiah Serven
In a sample of elliptical galaxies that span a large range of mass, a previously unused Ca index, CaHK, shows that [Ca/Fe] and [Ca/Mg] systematically decrease with increasing ellip…
Exploring the Correlations between Globular Cluster Populations and Supermassive Black Holes in Giant Galaxies
Katherine L. Rhode
This paper presents an analysis of the correlation between the number of globular clusters (N_GC) in giant galaxies and the mass of the galaxies' central supermassive black hole (M…
The Outer Disks of Dwarf Irregular Galaxies
Deidre A. Hunter, Bruce G. Elmegreen, Se-Heon Oh +5
To explore the properties of extreme outer stellar disks, we obtained ultra-deep V and GALEX UV images of 4 dwarf irregular galaxies and one Blue Compact Dwarf galaxy and ultra-dee…
The number density and mass density of star-forming and quiescent galaxies at 0.4 < z < 2.2
Gabriel B. Brammer, Katherine E. Whitaker, Pieter G. van Dokkum +9
We study the build-up of the bimodal galaxy population using the NEWFIRM Medium-Band Survey, which provides excellent redshifts and well-sampled spectral energy distributions of ~2…
Large-scale shock-ionized and photo-ionized gas in M83: the impact of star formation
Sungryong Hong, Daniela Calzetti, Michael A. Dopita +20
We investigate the ionization structure of the nebular gas in M83 using the line diagnostic diagram, [O III](5007 \degA)/Hβ vs. [S II](6716 °A+6731 °A)/Hα with the newly available…
Galaxy clustering in the NEWFIRM Medium Band Survey: the relationship between stellar mass and dark matter halo mass at 1 < z < 2
David A. Wake, Katherine E. Whitaker, Ivo Labbé +8
We present an analysis of the clustering of galaxies as a function of their stellar mass at 1 < z < 2 using data from the NEWFIRM Medium Band Survey (NMBS). The precise photometric…
Anatomy of a post-starburst minor merger: a multi-wavelength WFC3 study of NGC 4150
R. Mark Crockett, Sugata Kaviraj, Joseph I. Silk +22
(Abridged) We present a spatially-resolved near-UV/optical study of NGC 4150, using the Wide Field Camera 3 (WFC3) on board the Hubble Space Telescope. Previous studies of this ear…
Hubble Space Telescope Imaging of Lyman Alpha Emission at z=4.4
Steven L. Finkelstein, Seth H. Cohen, Rogier A. Windhorst +28
We present the highest redshift detections of resolved Lyman alpha emission, using Hubble Space Telescope/ACS F658N narrowband-imaging data taken in parallel with the Wide Field Ca…
The Atacama Cosmology Telescope: Physical Properties and Purity of a Galaxy Cluster Sample Selected via the Sunyaev-Zel'dovich Effect
Felipe Menanteau, Jorge Gonzalez, Jean-Baptiste Juin +48
We present optical and X-ray properties for the first confirmed galaxy cluster sample selected by the Sunyaev-Zel'dovich Effect from 148 GHz maps over 455 square degrees of sky mad…
