The Topology of the IRAS Point Source Catalogue Redshift Survey
A. Canavezes, V. Springel, S. J. Oliver +10
We investigate the topology of the new Point Source Catalogue Redshift Survey (PSCz) of IRAS galaxies by means of the genus statistic. The survey maps the local Universe with appro…
Survival of Substructure within Dark Matter Haloes
Giuseppe Tormen, Antonaldo Diaferio, David Syer
Using high resolution cosmological N-body simulations, we investigate the survival of dark matter satellites falling into larger haloes. Satellites preserve their identity for some…
The colours of z=2 QSO host galaxies
I. Aretxaga, R. J. Terlevich, B. J. Boyle
Three high-redshift (z=2) and high luminosity (M_B < -28 mag for Ho = 50, qo=0.5) QSOs, two radio-quiet one radio-loud, were imaged in R, I and K bands. The luminosities, colours a…
Effects of Disks on Gravitational Lensing by Spiral Galaxies
Matthias Bartelmann, Abraham Loeb
Gravitational lensing of a quasar by a spiral galaxy should often be accompanied by damped Lyman-alpha absorption and dust extinction due to the intervening gaseous disk. In nearly…
A Minihalo Model for the Lyman Limit Absorption Systems at High Redshift
Tom Abel, H. J. Mo
We propose that a large fraction of the QSO Lyman limit absorption systems (LLS) observed at high redshift (z > 3) originate from gas trapped in small objects, such as minihalos, t…
A dynamical model for the penumbral fine structure and the Evershed effect in sunspots
R. Schlichenmaier, K. Jahn, H. U. Schmidt
Relying on the assumption that the interchange convection of magnetic flux tubes is the physical cause for the existence of sunspot penumbrae, we propose a model in which the dynam…
Quasars around the Seyfert Galaxy NGC3516
Y. Chu, J. Wei, J. Hu +2
We report redshift measurements of 5 X-ray emitting blue stellar objects (BSO's) located less than 12 arc min from the X-ray Seyfert galaxy, NGC 3516. We find these quasars to be d…
A global descriptor of spatial pattern interaction in the galaxy distribution
Martin Kerscher, Maria Jesus Pons-Borderia, Jens Schmalzing +4
We present the function J as a morphological descriptor for point patterns formed by the distribution of galaxies in the Universe. This function was recently introduced in the fiel…
The Evolution of Surface Parameters of Rotating Massive Stars
Norbert Langer, Alexander Heger
We summarize the present status of the predictions of massive star models for the evolution of their surface properties. After discussing luminosity, temperature and chemical compo…
R-Process in Collapsing O/Ne/Mg Cores
J. Craig Wheeler, John J. Cowan, Wolfgang Hillebrandt
Several circumstantial arguments point to the formation of the third r-process peak at A about 190, near platinum, in stars of mass of about 8-10 solar masses: 1) The delayed produ…
Light Nuclei near Neutron and Proton Drip Lines in the Relativistic Mean-Field Theory
G. A. Lalazissis, A. R. Farhan, M. M. Sharma
We have made a detailed study of the ground-state properties of nuclei in the light mass region with atomic numbers Z=10-22 in the framework of the relativistic mean-field (RMF) th…
Bolometric light curves of supernovae and post-explosion magnetic fields
P. Ruiz-Lapuente, H. Spruit
The various effects leading to diversity in the bolometric light curves of supernovae are examined: nucleosynthesis, kinematic differences, ejected mass, degree of mixing, and conf…
Expansions for nearly Gaussian distributions
S. Blinnikov, R. Moessner
Various types of expansions in series of Chebyshev-Hermite polynomials currently used in astrophysics for weakly non-normal distributions are compared, namely the Gram-Charlier, Ga…
Tidal Disruption Eddington Envelopes around Massive Black Holes
Andrew Ulmer, Bohdan Paczynski, Jeremy Goodman
Optically-thick envelopes may form following the tidal disruption of a star by a massive black hole. Such envelopes would reprocess hard radiation from accretion close to the black…
Photon Dispersion in a Supernova Core
A. Kopf, G. Raffelt
While the photon forward-scattering amplitude on free magnetic dipoles (e.g. free neutrons) vanishes, the nucleon magnetic moments still contribute significantly to the photon disp…
Multicolour imaging of z= 2 QSO hosts
I. Aretxaga, R. J. Terlevich, B. J. Boyle
We present multicolour images of the hosts of three z=2 QSOs previously detected in R-band by our group. The luminosities, colours and sizes of the hosts overlap with those of acti…
Simulations of non-axisymmetric rotational core collapse
M. Rampp, E. Mueller, M. Ruffert
We report on the first three-dimensional hydrodynamic simulations of secular and dynamical non-axisymmetric instabilities in collapsing, rapidly rotating stellar cores which extend…
A comparative modeling of supernova 1993J
S. I. Blinnikov, R. Eastman, O. S. Bartunov +2
The light curve of Supernova (SN) 1993J is calculated using two approaches to radiation transport as exemplified by the two computer codes, STELLA and EDDINGTON. Particular attenti…
Linking Cluster Formation to Large Scale Structure
J. M. Colberg, S. D. M. White, A. Jenkins +1
We use two high resolution CDM simulations to show that (i) when clusters of galaxies form the infall pattern of matter is not random but shows clear features which are correlated…
Genus Statistics of the Virgo N-body simulations and the 1.2-Jy Redshift Survey
V. Springel, S. D. M. White, J. M. Colberg +8
We study the topology of the Virgo N-body simulations and compare it to the 1.2-Jy redshift survey of IRAS galaxies by means of the genus statistic. Four high-resolution simulation…
Scale dependence of the bias investigated by weak lensing
Ludovic Van Waerbeke
The statistical analysis of the lensing effects coupled with the statistical analysis of the number counts is a tool to probe directly the relation between the mass and the light.…
The "Tip" of the Red Giant Branch as a distance indicator: theoretical calibration and the value of H_0
S. Cassisi, M. Salaris
Updated theoretical relations for the run of the bolometric and I magnitude of the Tip of the Red Giant Branch (TRGB) with respect to the metallicity are provided. An analogous rel…
Cosmological Vorticity in a Gravity with Quadratic Order Curvature Couplings
J. Hwang, H. Noh
We analyse the evolution of the rotational type cosmological perturbation in a gravity with general quadratic order gravitational coupling terms. The result is expressed independen…
The cosmological parameters from supernovae
P. Ruiz-Lapuente
Supernovae are bright luminous stellar objects observable up to redshifts close to z~1. They are used to probe the geometry of the Universe and its expansion rate by applying diffe…
