Progress in Multi-Wavelength and Multi-Messenger Observations of Blazars and Theoretical Challenges [PDF]

Galaxies, 2019
This review provides an overview of recent advances in multi-wavelength and multi-messenger observations of blazars, the current status of theoretical models for blazar emission, and prospects for future facilities.

Did IceCube discover dark matter around blazars?

Physical Review D
Models of blazar jets, that explain observations of their photon spectra, typically predict too few neutrinos to be possibly seen by existing telescopes.

Microvariability in Blazars

Astrophysics and Space Science, 1997
Optically violent variable quasars and BL Lac objects, which form a subclass of active galactic nuclei are termed as Blazars. Blazars show high degree variation in their flux and polarization in a relatively shorter period of time. They are strong radio sources with a non-stellar continuum.

Blazars and INTEGRAL

Chinese Journal of Astronomy and Astrophysics, 2006
We refer to analysis of the ESA INTEGRAL satellite data for specific class of active galactic nuclei - blazars. These objects represent promising sources to be observed by INTEGRAL, especially during their active states. Suitable strategy for the future analysis is proposed and discussed.

Flares in Blazars

2009
Blazars are active galactic nuclei characterized by strong, nearly pure non-thermal radiations; these extend across the electromagnetic spectrum, from radio frequencies to the most energetics γ rays observed, in some cases up to TeV energies.

Blazar periodico

2014
Un gruppo di ricerca di astrofisica italiano ha recentemente confermato una scoperta intrigante riguardo ad uno dei più noti e studiati blazar: l’oggetto denominato PKS2155-304. Tramite osservazioni ottenute con il telescopio INAF REM ed osservazioni ad alta energia ottenute con il satellite NASA Fermi, si è determinata l’esistenza di una periodicità ...
