Cosmic Ray Production of Li by Virialization Shocks in the Early Milky Way
Takeru K. Suzuki, Susumu Inoue
The energy dissipated by virialization shocks during hierarchical structure formation of the Galaxy can exceed that injected by concomitant supernova (SN) explosions. Cosmic rays (…
A Catalog of Compact Groups of Galaxies in the SDSS Commissioning Data
B. C. Lee, S. S. Allam, D. L. Tucker +20
Compact groups (CGs) of galaxies -- relatively poor groups of galaxies in which the typical separations between members is of the order of a galaxy diameter -- offer an exceptional…
Excess mid-IR emission in Cataclysmic Variables
G. Dubus, R. Campbell, B. Kern +2
We present a search for excess mid-IR emission due to circumbinary material in the orbital plane of cataclysmic variables (CVs). Our motivation stems from the fact that the strong…
Newly Discovered Globular Clusters in the Outer Halo of M31
A. Huxor, N. R. Tanvir, M. Irwin +4
We present nine newly discovered globular clusters in the outer halo of M31, found by a semi-automated procedure from a INT Wide Field Camera survey of the region. The sample inclu…
CMB Observations and the Production of Chemical Elements at the End of the Dark Ages
K. Basu, C. Hernandez-Monteagudo, R. Sunyaev
The metallicity evolution and ionization history of the universe must leave its imprint on the Cosmic Microwave Background through resonant scattering of CMB photons by atoms, ions…
The Cellular Burning Regime in Type Ia Supernova Explosions - II. Flame Propagation into Vortical Fuel
F. K. Roepke, W. Hillebrandt, J. C. Niemeyer
We investigate the interaction of thermonuclear flames in Type Ia supernova explosions with vortical flows by means of numerical simulations. In our study, we focus on small scales…
The Cellular Burning Regime in Type Ia Supernova Explosions - I. Flame Propagation into Quiescent Fuel
F. K. Roepke, W. Hillebrandt, J. C. Niemeyer
We present a numerical investigation of the cellular burning regime in Type Ia supernova explosions. This regime holds at small scales (i.e. below the Gibson scale), which are unre…
Comparing AMR and SPH Cosmological Simulations: I. Dark Matter & Adiabatic Simulations
Brian W. O'Shea, Kentaro Nagamine, Volker Springel +2
We compare two cosmological hydrodynamic simulation codes in the context of hierarchical galaxy formation: The SPH code GADGET, and the Eulerian AMR code ENZO. Both codes represent…
Statistical properties of the combined emission of a population of discrete sources: astrophysical implications
M. Gilfanov, H-J. Grimm, R. Sunyaev
We study the statistical properties of the combined emission of a population of discrete sources (e.g. X-ray emission of a galaxy due to its X-ray binaries population). Namely, we…
Early Formation and Late Merging of the Giant Galaxies
Liang Gao, Abraham Loeb, P. J. E. Peebles +2
The most luminous galaxies in the present Universe are found at the centers of the most massive dark matter haloes, rich galaxy clusters. In the LCDM cosmology, such massive halo c…
Star formation history and dust attenuation in galaxies drawn from ultraviolet surveys
X. Kong, S. Charlot, J. Brinchmann +1
We compile a new sample of 115 nearby, non-Seyfert galaxies spanning a wide range of star formation activities, from starburst to nearly dormant, based on ultraviolet (UV) observat…
Local redshift surveys and galaxy evolution
Roberto De Propris, Matthew Colless, Darren Croton
We present observations of galaxy environmental dependencies using data from the 2dF Galaxy Redshift Survey. From a combined analysis of the luminosity function, Butcher-Oemler eff…
Early results from the VIMOS VLT Deep Survey
O. Le Fèvre, G. Vettolani, D. Maccagni +40
The VIMOS VLT Deep Survey (VVDS) is underway to study the evolution of galaxies, large scale structures and AGNs, from the measurement of more than 100000 spectra of faint objects.…
Optical and Infrared Photometry of the Nearby Type Ia Supernovae 1999ee, 2000bh, 2000ca, and 2001ba
Kevin Krisciunas, Mark M. Phillips, Nicholas B. Suntzeff +20
We present near infrared photometry of the Type Ia supernova 1999ee; also, optical and infrared photometry of the Type Ia SNe 2000bh, 2000ca, and 2001ba. For SNe 1999ee and 2000bh…
XMM-Newton Witness of M86 X-ray Metamorphosis
A. Finoguenov, W. Pietsch, B. Aschenbach +1
The environmental influence of cluster media on its member galaxies, known as Butcher--Oemler effect, has recently been subject to revision due to numerous observations of strong m…
The Three-point Correlation Function of Galaxies Determined from the 2dF Galaxy Redshift Survey
Y. P. Jing, G. Boerner
In a detailed analysis of the three point correlation function (3PCF) for the 2dF Galaxy Redshift Survey we have accurately measured the 3PCF for galaxies of different luminosity.…
Photometric Properties of Lyman-break Galaxies at z=3 in Cosmological SPH Simulations
Kentaro Nagamine, Volker Springel, Lars Hernquist +1
We study the photometric properties of Lyman-break galaxies (LBGs) formed by redshift z=3 in a set of large cosmological smoothed-particle hydrodynamics simulations of the Lambda c…
Is There a Missing Galaxy Problem at High Redshift?
Kentaro Nagamine, Renyue Cen, Lars Hernquist +2
We study the evolution of the global stellar mass density in a Lambda cold dark matter universe using two different types of hydrodynamical simulations (Eulerian TVD and SPH) and t…
The Inner Structure of LambdaCDM Halos III: Universality and Asymptotic Slopes
Julio F. Navarro, Eric Hayashi, Chris Power +6
We investigate the mass profile of LambdaCDM halos using a suite of numerical simulations spanning five decades in halo mass, from dwarf galaxies to rich galaxy clusters. Our analy…
Galactic winds and the Lya forest
Vincent Desjacques, Adi Nusser, Martin G. Haehnelt +1
We study the effect of galactic outflows on the Lya forest. The winds are modelled as fully ionised spherical bubbles centered around galactic haloes. The observed flux probability…

A Test for the Origin of Quasar Redshifts
Piotr Popowski, Wolfgang Weinzierl
It is commonly accepted that quasar redshifts have a cosmological character and that most of the quasars are at Gigaparsec distances. However, there are some cases where several qu…
