We present the first quantified, statistical map of broad-line active galactic nucleus (AGN) frequency with host galaxy color and stellar mass in nearby (0.01 < z < 0.11) galaxies.…
Testing the dark matter origin of the WMAP-Planck Haze with radio observations of Spiral Galaxies
Eric Carlson, Dan Hooper, Tim Linden +1
If the Galactic WMAP radio haze, as recently confirmed by Planck, is produced by dark matter annihilation or decay, similar diffuse radio halos should exist around other galaxies w…
An Independent Measurement of the Incidence of MgII Absorbers along Gamma-Ray Burst Sightlines: the End of the Mystery?
A. Cucchiara, J. X. Prochaska, G. Zhu +15
In 2006, Prochter et al. reported a statistically significant enhancement of very strong Mg II absorption systems intervening the sightlines to gamma-ray bursts (GRBs) relative to…
A Substantial Mass of Cool, Metal-Enriched Gas Surrounding the Progenitors of Modern-Day Ellipticals
J. Xavier Prochaska, Joseph F. Hennawi, Robert A. Simcoe
The hosts of luminous z~2 quasars evolve into today's massive elliptical galaxies. Current theories predict that the circum-galactic medium (CGM) of these massive, dark-matter halo…
Shape Evolution of Massive Early-Type Galaxies: Confirmation of Increased Disk Prevalence at z>1
Yu-Yen Chang, Arjen van der Wel, Hans-Walter Rix +4
We use high-resolution K-band VLT/HAWK-I imaging over 0.25 square degrees to study the structural evolution of massive early-type galaxies since z~1. Mass-selected samples, complet…
Pseudobulge Formation as a Dynamical Rather than a Secular Process
Javiera Guedes, Lucio Mayer, Marcella Carollo +1
We investigate the formation and evolution of the pseudobulge in "Eris", a high-resolution N-body + smoothed particle hydrodynamics (SPH) cosmological simulation that successfully…
The Imprint of The Extragalactic Background Light in the Gamma-Ray Spectra of Blazars
LAT Collaboration
The light emitted by stars and accreting compact objects through the history of the Universe is encoded in the intensity of the extragalactic background light (EBL). Knowledge of t…
Characterizing the satellites of massive galaxies up to z~2: young populations to build the outskirts of nearby massive galaxies
Esther Marmol-Queralto, Ignacio Trujillo, Victor Villar +2
The accretion of minor satellites is currently proposed as the most likely mechanism to explain the significant size evolution of the massive galaxies during the last ~10 Gyr. In t…
A Rest-frame Optical View on z~4 Galaxies I: Color and Age Distributions from Deep IRAC Photometry of the IUDF10 and GOODS Surveys
P. A. Oesch, I. Labbe, R. J. Bouwens +7
We present a study of rest-frame UV-to-optical color distributions for z~4 galaxies based on the combination of deep HST/ACS+WFC3/IR data with Spitzer/IRAC imaging. In particular,…
Structural Parameters of Galaxies in CANDELS
A. van der Wel, E. F. Bell, B. Haussler +19
We present global structural parameter measurements of 109,533 unique, H_F160W-selected objects from the CANDELS multi-cycle treasury program. Sersic model fits for these objects a…
Widespread and Hidden Active Galactic Nuclei in Star-Forming Galaxies at Redshift > 0.3
Stéphanie Juneau, Mark Dickinson, Frédéric Bournaud +23
We characterize the incidence of active galactic nuclei (AGNs) is 0.3 < z < 1 star-forming galaxies by applying multi-wavelength AGN diagnostics (X-ray, optical, mid-infrared, radi…
Finding the First Cosmic Explosions I: Pair-Instability Supernovae
Daniel J. Whalen, Wesley Even, Lucille H. Frey +9
The first stars are the key to the formation of primitive galaxies, early cosmological reionization and chemical enrichment, and the origin of supermassive black holes. Unfortunate…
Photometric Constraints on the Redshift of z~10 candidate UDFj-39546284 from deeper WFC3/IR+ACS+IRAC observations over the HUDF
R. J. Bouwens, P. A. Oesch, G. D. Illingworth +10
Ultra-deep WFC3/IR observations on the HUDF from the HUDF09 program revealed just one plausible z~10 candidate UDFj-39546284. UDFj-39546284 had all the properties expected of a gal…
The explosion energy of early stellar populations: The Fe-peak element ratios in low metallicity damped Lyman-alpha systems
Ryan Cooke, Max Pettini, Regina A. Jorgenson +3
The relative abundances of the Fe-peak elements (Ti-Zn) at the lowest metallicities are intimately linked to the physics of core-collapse supernova explosions. With a sample of 25…
