An optimal filter for the detection of galaxy clusters through weak lensing
M. Maturi, M. Meneghetti, M. Bartelmann +2
We construct a linear filter optimised for detecting dark-matter halos in weak-lensing data. The filter assumes a mean radial profile of the halo shear pattern and modifies that sh…
High velocity features in the spectra of the Type Ia SN 1999ee: a property of the explosion or evidence of circumstellar interaction?
P. A. Mazzali, S. Benetti, M. Stehle +5
The near-maximum spectra of the Type Ia SN 1999ee are reviewed. Two narrow absorption features corresponding to the strongest component of the CaII IR triplet appear in the spectra…
Gravitational lensing of the CMB by galaxy clusters
M. Maturi, M. Bartelmann, M. Meneghetti +1
We adapt a non-linear filter proposed by Hu 2001 for detecting lensing of the CMB by large-scale structures to recover surface-density profiles of galaxy clusters from their locali…
Hard X-ray sky survey with the SIGMA telescope aboard GRANAT observatory
M. G. Revnivtsev, R. A. Sunyaev, M. R. Gilfanov +5
During the lifetime of GRANAT orbital observatory the SIGMA telescope collected X-ray images of more than 1/4 of the whole sky. Among these regions the Galactic Center had largest…
The 2D Continuum Radiative Transfer Problem: Benchmark Results for Disk Configurations
I. Pascucci, S. Wolf, J. Steinacker +5
We present benchmark problems and solutions for the continuum radiative transfer (RT) in a 2D disk configuration. The reliability of three Monte-Carlo and two grid-based codes is t…
