Interstellar extinction: a parametrical study by using laboratory data.
Mennella, V.; Colangeli, L.; Rotundi, A. +2 more
The authors present a comparative study between laboratory data, astronomical observations and theoretical models in order to provide a contribution to the characterization of cosmic-dust properties. In particular, they propose a parametrization of the amorphous-carbon extinction curve. The laboratory extinction measurements, performed in the extr…
How robust are the EGRET AGN gamma-ray identifications?
Bignami, G. F.; Caraveo, P.; Ciliegi, P.
Several AGNs have been proposed as identifications of gamma-ray sources discovered by CGRO. Using the NED database, the authors show that these AGNs are not the only extragalactic objects within the error boxes of the sources. Therefore, an in-depth study is needed on a case-by-case basis to access the most probable counterparts of the gamma-ray s…
