Weak Gravitational Lensing
Matthias Bartelmann, Peter Schneider
We review theory and applications of weak gravitational lensing. After summarising Friedmann-Lemaitre cosmological models, we present the formalism of gravitational lensing and lig…
Mass loss from a magnetically driven wind emitted by a disk orbiting a stellar mass black hole
Frederic Daigne, Robert Mochkovitch
The source of cosmic gamma-ray bursts (hereafter GRBs) is usually believed to be a stellar mass black hole accreting material from a thick disk. The mechanism for the production of…
Statistics of Weak Lensing at Small Angular Scales: Analytical Predictions for Lower Order Moments
Dipak Munshi, Bhuvnesh Jain
Weak lensing surveys are expected to provide direct measurements of the statistics of the projected dark matter distribution. Most analytical studies of weak lensing statistics hav…
Experimental Cosmic Statistics II: Distribution
István Szapudi, Stéphane Colombi, Adrian Jenkins +1
Colombi et al. 1999 (paper I) investigated the counts-in-cells statistics and their respective errors in the CDM Virgo Hubble Volume simulation. This extremely large -body ex…
Experimental Cosmic Statistics I: Variance
Stéphane Colombi, István Szapudi, Adrian Jenkins +1
Counts-in-cells are measured in the CDM Virgo Hubble Volume simulation. This large N-body experiment has 10^9 particles in a cubic box of size 2000 h^{-1} Mpc. The unprecedented…
The IRAS PSCz Dipole
M. Rowan-Robinson, J. Sharpe, S. J. Oliver +12
We use the PSCz IRAS galaxy redshift survey to analyze the cosmological galaxy dipole out to a distance 300 h Mpc. The masked area is filled in three different ways, firstly…
Redshift-Distance Survey of Early-type Galaxies. I. Sample Selection, Properties and Completeness
L. N. da Costa, M. Bernardi, M. V. Alonso +5
This is the first in a series of papers describing the recently completed all-sky redshift-distance survey of nearby early-type galaxies (ENEAR) carried out for peculiar velocity a…
Early planet formation as a trigger for further planet formation
Philip J. Armitage, Brad M. S. Hansen
Recent discoveries of extrasolar planets at small orbital radii, or with significant eccentricities, indicate that interactions between massive planets and the disks of gas and dus…
Radio galaxies with a `double-double' morphology: II - The evolution of double-double radio galaxies and implications for the alignment effect in FRII sources
Christian R. Kaiser, A. P. Schoenmakers, H. J. A. Rottgering
A Double-Double Radio Galaxy (DDRG) is defined as consisting of a pair of double radio sources with a common centre. In this paper we present an analytical model in which the pecul…
Radio galaxies with a `double-double' morphology: I - Analysis of the radio properties and evidence for interrupted activity in active galactic nuclei
Arno P. Schoenmakers, A. G. de Bruyn, H. J. A. Rottgering +2
We present four Mpc-sized radio galaxies which consist of a pair of double-lobed radio sources, aligned along the same axis, and with a coinciding radio core. We have called these…
Non-Voigt Lyman-alpha absorption line profiles
P. J. Outram, R. F. Carswell, T. Theuns
Recent numerical simulations have lead to a paradigm shift in our understanding of the intergalactic medium, and the loss of a physical justification for Voigt profile fitting of t…
Non-linear Stochastic Galaxy Biasing in Cosmological Simulations
R. S. Somerville, G. Lemson, Y. Sigad +3
We study the biasing relation between dark-matter halos or galaxies and the underlying mass distribution, using cosmological -body simulations in which galaxies are modelled via…
The thermal history of the intergalactic medium
Joop Schaye, Tom Theuns, Michael Rauch +2
At redshifts z >~ 2, most of the baryons reside in the smooth intergalactic medium which is responsible for the low column density Lyman-alpha forest. This photoheated gas follows…
Backward asymmetry of the Compton scattering by an isotropic distribution of relativistic electrons: astrophysical implications
Sergei Y. Sazonov, Rashid A. Sunyaev
The angular distribution of low-frequency radiation after single scattering by an isotropic distribution of relativistic electrons considerably differs from the Rayleigh angular fu…
Age-luminosity relations for low-mass metal-poor stars
Achim Weiss, Helmut Schlattl
We present a grid of evolutionary calculations for metal-poor low-mass stars for a variety of initial helium and metal abundances. The intention is mainly to provide a database for…
Electron-, Mu-, and Tau-Number Conservation in a Supernova Core
S. Hannestad, H. -T. Janka, G. G. Raffelt +1
We study if the neutrino mixing parameters suggested by the atmospheric neutrino anomaly imply chemical equilibrium between mu- and tau-flavored leptons in a supernova (SN) core. T…
Redshift-Distance Survey of Early-Type Galaxies. IV. Dipoles of the Velocity Field
L. N. da Costa, M. Bernardi, M. V. Alonso +5
We use the recently completed redshift-distance survey of nearby early-type galaxies (ENEAR) to measure the dipole component of the peculiar velocity field to a depth of cz ~ 6000…
Large scale motions in superclusters: their imprint in the CMB
Antonaldo Diaferio, Rashid A. Sunyaev, Adi Nusser
We identify high density regions of supercluster size in high resolution N-body simulations of a representative volume of three Cold Dark Matter Universes. By assuming that (1) the…
The formation and evolution of supermassive black holes and their host galaxies
Martin G. Haehnelt, Guinevere Kauffmann
We discuss constraints on the assembly history of supermassive black holes from the observed remnant black holes in nearby galaxies and from the emission caused by accretion onto t…
The Statistics of Weak Lensing at Small Angular Scales: Probability Distribution Function
Dipak Munshi, Bhuvnesh Jain
Weak gravitational lensing surveys have the potential to directly probe mass density fluctuation in the universe. Recent studies have shown that it is possible to model the statist…
Probing Solar Convection
M. Brüggen
In the solar convection zone acoustic waves are scattered by turbulent sound speed fluctuations. In this paper the scattering of waves by convective cells is treated using Rytov's…
