Restrictions on the parameters of boundary layer and accretion disk of X-ray bursters in the low state
M. Revnivtsev, M. Gilfanov, E. Churazov +1
Using ASCA observations of several X-ray bursters in the low spectral state Lx~1-5x10^{36} erg/s) restrictions on the parameters of the accretion disk and the boundary layer were o…
Intergalactic H_2 Photodissociation and the Soft UV Background Produced by Population III Objects
Benedetta Ciardi, Andrea Ferrara, Tom Abel
We study the effects of the ionizing and dissociating photons produced by PopIII objects on the surrounding intergalactic medium. We find that the typical size of a H_2 photodissoc…
Natural Polarization Modes in Pulsar Magnetospheres
Alexis von Hoensbroech, Harald Lesch, Thomas Kunzl
We present a comprehensive investigation of the radio polarization properties within the theory of natural electromagnetic wave modes in pulsar magnetospheres. Taking into account…
High resolution imaging of the X-ray afterglow of GRB970228 with ROSAT
F. Frontera, J. Greiner, L. A. Antonelli +6
We report results of a ROSAT High-Resolution Imager (HRI) observation of the X-ray error box given by the BeppoSAX Wide Field Camera for the gamma-ray burst that occurred on 1997 F…
Entropy-regularized Maximum-Likelihood cluster mass reconstruction
Stella Seitz, Peter Schneider, Matthias Bartelmann
We present a new method for reconstructing two-dimensional mass maps of galaxy clusters from the image distortion of background galaxies. In contrast to most previous approaches, w…
A new finite-field mass reconstruction algorithm
Stella Seitz, Peter Schneider
A new method for the reconstruction of the projected mass distribution of clusters of galaxies from the image distortion of background galaxies is discussed. This method is essenti…
