A Comparison between Semi-Analytic Model Predictions for the CANDELS Survey
Yu Lu, Risa H. Wechsler, Rachel S. Somerville +13
We compare the predictions of three independently developed semi-analytic galaxy formation models that are being used to aid in the interpretation of results from the CANDELS surve…
AGN X-ray variability in the XMM-COSMOS survey

We took advantage of the observations carried out by XMM in the COSMOS field during 3.5 years, to study the long term variability of a large sample of AGN (638 sources), in a wide…
Constraints on the merging channel of massive galaxies since z~1
I. Ferreras, I. Trujillo, E. Mármol-Queraltó +8
(Abridged) We probe the merging channel of massive galaxies over the z=0.3-1.3 redshift window by studying close pairs in a sample of 238 galaxies with stellar mass >1E11Msun, from…
The colour distribution of galaxies at redshift five

We present the results of a study investigating the rest-frame ultra-violet (UV) spectral slopes of redshift z~5 Lyman-break galaxies (LBGs). By combining deep Hubble Space Telesco…
MOND and IMF variations in early-type galaxies from
C. Tortora, A. J. Romanowsky, V. F. Cardone +2
MOdified Newtonian dynamics (MOND) represents a phenomenological alternative to dark matter (DM) for the missing mass problem in galaxies and clusters of galaxies. We analyze the c…
Confirmation of Small Dynamical and Stellar Masses for Extreme Emission Line Galaxies at z~2

A CANDELS - 3D-HST Synergy: Resolved Star Formation Patterns at 0.7 < z < 1.5
Stijn Wuyts, Natascha M. Forster Schreiber, Erica J. Nelson +20
We analyze the resolved stellar populations of 473 massive star-forming galaxies at 0.7 < z < 1.5, with multi-wavelength broad-band imaging from CANDELS and Halpha surface brightne…
The Progenitors of the Compact Early-Type Galaxies at High-Redshift
Christina C. Williams, Mauro Giavalisco, Paolo Cassata +19
We use GOODS and CANDELS images to identify progenitors of massive (log M > 10 Msun) compact "early-type" galaxies (ETGs) at z~1.6. Since merging and accretion increase the size of…
The SLUGGS Survey: The globular cluster systems of three early-type galaxies using wide-field imaging
Sreeja S. Kartha, Duncan A. Forbes, Lee R. Spitler +3
We present the results from a wide-field imaging study of globular cluster (GC) systems in three early-type galaxies. Combinations of Subaru/Suprime-Cam, CFHT/MegaCam and HST/WFPC2…
The SLUGGS Survey: Wide-field Stellar Kinematics of Early-type Galaxies
Jacob A. Arnold, Aaron J. Romanowsky, Jean P. Brodie +10
We present stellar kinematics of 22 nearby early-type galaxies (ETGs), based on two-dimensional (2D) absorption line stellar spectroscopy out to ~2-4 R_e (effective radii), as part…
A Budget and Accounting of Metals at z~0: Results from the COS-Halos Survey
Molly S. Peeples, Jessica K. Werk, Jason Tumlinson +4
We present a budget and accounting of metals in and around star-forming galaxies at . We combine empirically derived star formation histories with updated supernova and AG…
Towards a Unified Description of the Intergalactic Medium at Redshift z~2.5
J. Xavier Prochaska, Piero Madau, John M. O'Meara +1
We examine recent measurements of the z~2.5 intergalactic medium (IGM) which constrain the HI frequency distribution f(N) and the mean free path MFP to ionizing radiation. We argue…
The COS-Halos Survey: Rationale, Design, and A Census of Circumgalactic Neutral Hydrogen
Jason Tumlinson, Christopher Thom, Jessica Werk +11
We present the design and methods of the COS-Halos survey, a systematic investigation of the gaseous halos of 44 z = 0.15-0.35 galaxies using background QSOs observed with the Cosm…
Discovery of a Quadruple Lens in CANDELS with a Record Lens Redshift z=1.53
A. van der Wel, G. van de Ven, M. Maseda +10
Using spectroscopy from the Large Binocular Telescope and imaging from the Hubble Space Telescope we discovered the first strong galaxy lens at z(lens)>1. The lens has a secure pho…
Do We Expect Most AGN to Live in Disks?
Philip F. Hopkins, Dale D. Kocevski, Kevin Bundy
Recent observations have indicated that a large fraction of the low to intermediate luminosity AGN population lives in disk-dominated hosts, while the more luminous quasars live in…
The SLUGGS Survey: Wide Field Imaging of the Globular Cluster System of NGC 4278
