Simple Models for the Distribution of Dark Matter

Jin H. An, N. Wyn Evans

We introduce a simple family of models for representing the dark matter in galaxies. The potential and phase space distribution function are all elementary, while the density is cu…

Thermal and non-thermal energies in solar flares

Pascal Saint-Hilaire, Arnold O. Benz

The energy of the thermal flare plasma and the kinetic energy of the non-thermal electrons in 14 hard X-ray peaks from 9 medium-sized solar flares have been determined from RHESSI…

Continuous star formation in gas-rich dwarf galaxies

S. Recchi, G. Hensler

Blue Compact Dwarf and Dwarf Irregular galaxies are generally believed to be unevolved objects, due to their blue colors, compact appearance and large gas fractions. Many of these…

Photometric Variability in the Faint Sky Variability Survey

L. Morales-Rueda, P. J. Groot, T. Augusteijn +3

The Faint Sky Variability Survey (FSVS) is aimed at finding photometric and/or astrometric variable objects between 16th and 24th mag on time-scales between tens of minutes and yea…

Gravitational lens under perturbations: Symmetry of perturbing potentials with invariant caustics

Jin H. An

When the gravitational lensing potential can be approximated by that of circularly symmetric system affected by weak perturbations, it is found that the shape of the resulting (tan…

A Matched Catalogue i-dropout galaxies at z~6 in the Hubble Ultra Deep Field

Andrew J Bunker, Elizabeth R. Stanway

A recent preprint by Yan & Windhorst (astro-ph/0407493) independently repeats our selection of candidate z~6 galaxies in the Hubble Ultra Deep Field (astro-ph/0403223). The agreeme…
