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…
HIFLUGCS: Galaxy cluster scaling relations between X-ray luminosity, gas mass, cluster radius, and velocity dispersion
Y. -Y. Zhang, H. Andernach, C. A. Caretta +5
We present relations between X-ray luminosity and velocity dispersion (L-sigma), X-ray luminosity and gas mass (L-Mgas), and cluster radius and velocity dispersion (r500-sigma) for…
The Impact of Gas Stripping and Stellar Mass Loss on Satellite Galaxy Evolution
Taysun Kimm, Sadegh Khochfar, Sukyoung Yi
Current semi-analytic models (SAMs) of galaxy formation over-predict the fraction of passive small late-type satellite galaxies in dense environments by a factor of two to three. W…
Scaling Rrelation in two situations of extreme mergers
Elena Rasia, Pasquale Mazzotta, August Evrard +3
Clusters of galaxies are known to be dynamically active systems, yet X-ray studies of the low redshift population exhibit tight scaling laws. In this work, we extend previous studi…
Suppression of accretion onto low-mass Population III stars
Jarrett L. Johnson, Sadegh Khochfar
Motivated by recent theoretical work suggesting that a substantial fraction of Population (Pop) III stars may have had masses low enough for them to survive to the present day, we…
The Dawn of the Red: Star formation histories of group galaxies over the past 5 billion years
Sean L. McGee, Michael L. Balogh, David J. Wilman +4
We examine the star formation properties of group and field galaxies in two surveys, the Sloan Digital Sky Survey (SDSS; at z ~ 0.08) and the Group Environment and Evolution Collab…
Velocity Structure Diagnostics of Simulated Galaxy Clusters
Veronica Biffi, Klaus Dolag, Hans Boehringer
Gas motions in the hot intracluster medium of galaxy clusters have an important effect on the mass determination of the clusters through X-ray observations. The corresponding dynam…
Disruption of Star Clusters in the Interacting Antennae Galaxies
Simon J. Karl, S. Michael Fall, Thorsten Naab
We reexamine the age distribution of star clusters in the Antennae in the context of N-body+hydrodynamical simulations of these interacting galaxies. All of the simulations that ac…
Confusing the extragalactic neutrino flux limit with a neutrino propagation limit
J. Barranco, O. G. Miranda, C. A. Moura +2
We study the possible suppression of the extragalactic neutrino flux due to a nonstandard interaction during its propagation. In particular, we study neutrino interaction with an u…
The scatter in the radial profiles of X-ray luminous galaxy clusters as diagnostic of the thermodynamical state of the ICM
F. Vazza, M. Roncarelli, S. Ettori +1
We study the azimuthal scatter in the radial profiles of X-ray luminous galaxy clusters, with two sets of high-resolution cosmological re-simulations obtained with the codes ENZO a…
Asymmetries in the Type IIn SN2010jl
F. Patat, S. Taubenberger, S. Benetti +2
Aims: We study possible signs of asymmetry in the luminous Type IIn SN2010jl, to obtain independent information on the explosion geometry. Methods: We obtained optical linear spect…
Reconstructing the massive black hole cosmic history through gravitational waves
Alberto Sesana, Jonathan R. Gair, Emanuele Berti +1
The massive black holes we observe in galaxies today are the natural end-product of a complex evolutionary path, in which black holes seeded in proto-galaxies at high redshift grow…
Effects of Varying the Three-Body Molecular Hydrogen Formation Rate in Primordial Star Formation
Matthew J. Turk, Paul Clark, S. C. O. Glover +4
The transformation of atomic hydrogen to molecular hydrogen through three-body reactions is a crucial stage in the collapse of primordial, metal-free halos, where the first generat…
Deep 21-cm HI Observations at z~0.1: The Precursor to the Arecibo Ultra Deep Survey
Wolfram Freudling, Lister Staveley-Smith, Barbara Catinella +6
The "ALFA Ultra Deep Survey" (AUDS) is an ongoing 21-cm spectral survey with the Arecibo 305m telescope. AUDS will be the most sensitive blind survey undertaken with Arecibo's 300…
The GALEX Arecibo SDSS survey: III. Evidence for the Inside-Out Formation of Galactic Disks
Jing Wang, Guinevere Kauffmann, Roderik Overzier +7
We analyze a sample of galaxies with stellar masses greater than and with redshifts in the range for which HI mass measurements are available fro…
Quasi-Stationary and Transient Patterns in Jets
A. P. Lobanov
Apparent evolution of relativistic flows as traced by radio emission results from a combination of several factors related to propagation of relativistic blobs or shocks, velocity,…
Local Gravity versus Local Velocity: Solutions for and nonlinear bias
Marc Davis, Adi Nusser, Karen Masters +3
(abridged) We perform a reconstruction of the cosmological large scale flows in the nearby Universe using two complementary observational sets. The first, the SFI++ sample of Tully…
Hot-Dust-Poor Type 1 Active Galactic Nuclei in the COSMOS Survey
Heng Hao, Martin Elvis, Francesca Civano +13
We report a sizable class of type 1 active galactic nuclei (AGNs) with unusually weak near-infrared (1-3μm) emission in the XMM-COSMOS type 1 AGN sample. The fraction of these "hot…
Demography of obscured and unobscured AGN: prospects for a Wide Field X-ray Telescope
R. Gilli, P. Tozzi, P. Rosati +7
We discuss some of the main open issues in the evolution of Active Galactic Nuclei which can be solved by the sensitive, wide area surveys to be performed by the proposed Wide Fiel…
Local non-Gaussianity in the Cosmic Microwave Background the Bayesian way
Franz Elsner, Benjamin D. Wandelt
We introduce an exact Bayesian approach to search for non-Gaussianity of local type in Cosmic Microwave Background (CMB) radiation data. Using simulated CMB temperature maps, the n…
Dust emission and star formation in Stephan's Quintet
G. Natale, R. J. Tuffs, C. K. Xu +11
We analyse a comprehensive set of MIR/FIR observations of Stephan's Quintet (SQ), taken with the Spitzer Space Observatory. Our study reveals the presence of a luminous (L_{IR}\app…
