EISily looking for distant galaxy clusters
Catarina Lobo, Davide Lazzati, Angela Iovino +2
We present a new algorithm to search for distant clusters of galaxies on catalogues deriving from imaging data, as those of the ESO Imaging Survey. We discuss the advantages of our…
Redshift determination in the X-ray band of gamma-ray bursts
G. Ghisellini, F. Haardt, S. Campana +2
If gamma-ray bursts originate in dense stellar forming regions, the interstellar material can imprint detectable absorption features on the observed X-ray spectrum. Such features c…
On the location of X-ray peaks and dominant galaxies in clusters
Davide Lazzati, Guido Chincarini
We analyze the structure of the X-ray emission of a sample of 22 Abell clusters of galaxies with a cD in their centre, observed with the ROSAT PSPC. Utilizing the multi-scale power…
