The Blazar PG 1553+113 as a Binary System of Supermassive Black Holes
Marco Tavani, Alfonso Cavaliere, Pere Munar-Adrover +1
The BL Lac PG 1553+113 has been continuously monitored in gamma rays with Fermi-LAT for over 9 years. Its updated light curve now includes 5 iterations of a main pattern comprising…
The Intragroup versus the Intracluster Medium
A. Cavaliere, R. Fusco-Femiano, A. Lapi
Galaxy groups differ from clusters primarily by way of their lower masses, M~10^14 M_sun vs. M~10^15 M_sun. We discuss how mass affects the thermal state of the intracluster or the…
Structure and History of Dark Matter Halos Probed with Gravitational Lensing
A. Lapi, A. Cavaliere
We test with gravitational lensing data the dark matter (DM) halos embedding the luminous baryonic component of galaxy clusters; our benchmark is provided by their two-stage cosmog…
The Optical-Radio Mapping: the kinetic efficiency of Radio-Loud AGNs
Francesco Shankar, Alfonso Cavaliere, Michele Cirasuolo +1
We constrain the mean kinetic efficiency of radio-loud active galactic nuclei by using an optically selected sample for which both the optical and the radio luminosity functions (L…
X-ray spectral evolution of TeV BL Lac objects: eleven years of observations with BeppoSAX, XMM-Newton and SWIFT satellites
F. Massaro, A. Tramacere, A. Cavaliere +2
Many of the extragalactic sources detected in rays at TeV energies are BL Lac objects. In particular, they belong to the subclass of ``high frequency peaked BL Lacs" (HBLs), as…
Missing Baryons, from Clusters to Groups of Galaxies
A. Cavaliere, A. Lapi
From clusters to groups of galaxies, the powerful bremsstrahlung radiation L_X emitted in X rays by the intracluster plasma is observed to decline sharply with lowering virial temp…
