Mass of BL Lacs from the Velocity Dispersion of the Host Galaxy
A. Treves, N. Carangelo, R. Falomo +1
We report on new measurements of the stellar velocity dispersion of 4 BL Lac objects for which optical spectroscopy was gathered at the ESO 3.6m using EFOSC2. Assuming the M(BH)--(…
Young compact objects in the Solar vicinity
S. B. Popov, M. E. Prokhorov, M. Colpi +2
We present Log N -- Log S distribution for close-by young isolated neutron stars. On the basis of this distribution it is shown that the seven ROSAT isolated neutron stars (if they…
Black hole masses of BL Lac objects
J. K. Kotilainen, R. Falomo, A. Treves
The correlation between black hole mass M(BH) and the central stellar velocity dispersion sigma in nearby elliptical galaxies affords a novel way to determine M(BH) in active galax…
Young close isolated compact objects
S. B. Popov, M. E. Prokhorov, M. Colpi +2
We suggest that the seven radio-quiet isolated neutron stars observed with ROSAT are young cooling objects associated to recent near-by supernova explosions which formed runaway st…
Isolated Neutron Stars in the Galaxy
S. B. Popov, M. E. Prokhorov, M. Colpi +3
In this article we briefly review our recent results on evolution and properties of isolated neutron stars (INSs) in the Galaxy. As the first step we calculate a {\it census} of IN…
Two BeppoSAX observations of BL Lac
G. Tagliaferri, G. Ghisellini, M. Ravasio +14
We present the results of two ToO BeppoSAX observations of BL Lac. During the first observation we detected both the synchrotron and the Compton components. Fast time variability w…
