Gamma-ray sources and connection with Gravitational Waves

Talk

The detection of continuous gravitational waves is among the main targets of the LIGO and Virgo detectors. Such kind of signals, emitted e.g. by spinning neutron stars asymmetric with respect to the rotation axis, are very weak and their search poses challenging data analysis problems. In this talk I will discuss the main issues regarding the search of continuous gravitational waves in the...

Gamma-ray sources

Talk

The Fermi Large Area Telescope (LAT) has been scanning the gamma-ray sky since 2008. The number of pulsars detected by the LAT now exceeds 200, making them by far the largest class of Galactic gamma-ray emitters. I will present some of the latest pulsar discoveries made by the LAT, describe the properties that make some of these systems unique and discuss them in the context of current pulsar...

Gravitational Waves

Talk

Non-axisymmetric spinning Neutron Stars are expected to be sources of continuous gravitational waves. Only a small fraction of the total number of neutron stars believed to exist in the Galaxy is observed through their electromagnetic emission. This number steadily increasing recently, thanks to the Fermi-Large Area Telescope and to radio surveys. The Fermi-Large Area Telescope catalogue...

132. The black hole binary model of OJ 287 as witness of the validity of the General Relativity

Gamma-ray sources and connection with Gravitational Waves

Talk

A peculiar and controversial phenomenology is the periodicity of AGN. This can be related to the indirect search for close supermassive black holes (SMBHs) at sub-parsec separation. A representative case study with multifrequency radio-optical and X-ray data, for example by XMM-Newton, Kepler, and Swift, is presented; namely the X-ray and gamma-ray BL Lac object OJ 287. This is one of the best...

95. The empirical grounds of SN-GRB connection

Gamma-ray sources and connection with Gravitational Waves

Talk

I will review the status of the SN-GRB connection. Present data suggest that SNe associated with GRBs form a heterogeneous class of objects including both bright and faint Hypernovae. Finally I’ll discuss the empirical estimate of the ratio GRB/SNe-Ibc, to be in the range ∼0.4%-3%.
