Probing the faint end of the quasar luminosity function at z ~ 4 in the COSMOS field
H. Ikeda, T. Nagao, K. Matsuoka +16
We searched for quasars that are ~ 3 mag fainter than the SDSS quasars in the redshift range 3.7 < z < 4.7 in the COSMOS field to constrain the faint end of the quasar luminosity f…
The Origin of [OII] Emission in Recently Quenched AGN Hosts
Dale D. Kocevski, Brian C. Lemaux, Lori M. Lubin +3
We have employed emission-line diagnostics derived from DEIMOS and NIRSPEC spectroscopy to determine the origin of the [OII] emission line observed in six AGN hosts at z~0.9. These…
Self-consistent evolution of gas and cosmic rays in Cygnus A and similar FR II classic double radio sources
William G. Mathews, Fulai Guo
In Cygnus A and other classical FR II double radio sources, powerful opposing jets from the cores of halo-centered galaxies drive out into the surrounding cluster gas, forming hots…
The Properties of X-ray Cold Fronts in a Statistical Sample of Simulated Galaxy Clusters
Eric J. Hallman, Samuel W. Skillman, Tesla E. Jeltema +4
We examine the incidence of cold fronts in a large sample of galaxy clusters extracted from a (512h^-1 Mpc) hydrodynamic/N-body cosmological simulation with adiabatic gas physics c…
Automated Morphological Classification of SDSS Red Sequence Galaxies
Judy Y. Cheng, S. M. Faber, Luc Simard +4
(abridged) In the last decade, the advent of enormous galaxy surveys has motivated the development of automated morphological classification schemes to deal with large data volumes…
Spitzer IRS 16 micron Observations of the GOODS Fields
Harry I. Teplitz, Ranga Chary, David Elbaz +13
We present Spitzer 16 micron imaging of the Great Observatories Origins Deep Survey (GOODS) fields. We survey 150 square arcminutes in each of the two GOODS fields (North and South…
High Dust Depletion in Two Intervening Quasar Absorption Line Systems with the 2175-Å Extinction Bump at
Peng Jiang, Jian Ge, J. Xavier Prochaska +3
We present the column densities of heavy-elements and dust depletion studies in twostrong Mg~II absorption systems at displaying the 2175-Å dust extinction feature. Colu…
Cosmic Ray-Dominated AGN Jets and the Formation of X-ray Cavities in Galaxy Clusters
Fulai Guo, William G. Mathews
It is widely accepted that feedback from active galactic nuclei (AGN) plays a key role in the evolution of gas in groups and clusters of galaxies. Unequivocal evidence comes from q…
A High-Velocity Narrow Absorption Line Outflow in the Quasar J212329.46-005052.9
F. Hamann, N. Kanekar, J. X. Prochaska +5
We report on a variable high-velocity narrow absorption line outflow in the redshift 2.3 quasar J2123-0050. Five distinct outflow systems are detected with velocity shifts from -97…
Low-ionization Line Emission from Starburst Galaxies: A New Probe of Galactic-Scale Outflows
Kate H. R. Rubin, J. Xavier Prochaska, Brice Ménard +4
We study the kinematically narrow, low-ionization line emission from a bright, starburst galaxy at z = 0.69 using slit spectroscopy obtained with Keck/LRIS. The spectrum reveals st…
Dissecting the Red Sequence. IV. The Role of Truncation in the Two-Dimensional Family of Early-Type Galaxy Star Formation Histories
Genevieve J. Graves, S. M. Faber, Ricardo P. Schiavon
In the three-dimensional parameter space defined by velocity dispersion, effective radius (R_e), and effective surface brightness (I_e), early-type galaxies are observed to populat…
Cosmological concordance or chemical coincidence? Deuterated molecular hydrogen abundances at high redshift
J. Tumlinson, A. L. Malec, R. F. Carswell +8
We report two detections of deuterated molecular hydrogen (HD) in QSO absorption-line systems at . Toward J2123-0500, we find (HD) for a sub-DLA with me…
Galaxies in LCDM with Halo Abundance Matching: luminosity-velocity relation, baryonic mass-velocity relation, velocity function and clustering
Sebastian Trujillo-Gomez, Anatoly Klypin, Joel Primack +1
It has long been regarded as difficult for a cosmological model to account simultaneously for the galaxy luminosity, mass, and velocity distributions. We revisit this issue using a…
Dissecting the Red Sequence - III. Mass-to-Light Variations in 3D Fundamental Plane Space
Genevieve J. Graves, S. M. Faber
The Fundamental Plane has finite thickness and is tilted from the virial relation, indicating that dynamical mass-to-light ratios (Mdyn/L) vary among early type galaxies. We use a…
Hot Gas Halos in Early-Type Field Galaxies
John S. Mulchaey, Tesla E. Jeltema
We use Chandra and XMM-Newton to study the hot gas content in a sample of field early-type galaxies. We find that the L_X-L_K relationship is steeper for field galaxies than for co…
H I Column Densities, Metallicities, and Dust Extinction of Metal-Strong Damped Lya Systems
Kyle F. Kaplan, J. Xavier Prochaska, Stephane Herbert-Fort +2
With the Blue Channel Spectrograph (BCS) on the MMT telescope, we have obtained spectra to the atmospheric cutoff of quasars previously known to show at least one absorption system…
Feedback under the microscope II: heating, gas uplift, and mixing in the nearest cluster core
N. Werner, A. Simionescu, E. T. Million +11
Using a combination of deep 574ks Chandra data, XMM-Newton high-resolution spectra, and optical Halpha+NII images, we study the nature and spatial distribution of the multiphase pl…
The Mid-Infrared Luminosities of Normal Galaxies over Cosmic Time
Daniel D. Kelson, Bradford P. Holden
Modern population synthesis models estimate that 50% of the restframe K-band light is produced by TP-AGB stars during the first Gyr of a stellar population, with a substantial frac…
