Blazar spectral variability as explained by a twisting inhomogeneous jet
C. M. Raiteri, M. Villata
Blazar emission is dominated by non-thermal radiation from a relativistic jet pointing toward us, therefore undergoing Doppler beaming. This is responsible for flux enhancement and…
Dissecting the long-term emission behaviour of the BL Lac object Mrk 421
M. I. Carnerero, C. M. Raiteri, M. Villata +4
We report on long-term multi-wavelength monitoring of blazar Mrk 421 by the GASP-WEBT collaboration and Steward Observatory, and by the Swift and Fermi satellites. We study the sou…
MAGIC observations of variable very-high-energy gamma-ray emission from PKS1510-089 during May 2015 outburst
Julian Sitarek, Josefa Becerra González, Vandad Fallah Ramazani Elina Lindfors +11
PKS1510-089 is a flat spectrum radio quasar located at a redshift of 0.36. It is one of only a few such sources detected in very-high-energy (VHE, >100 GeV) gamma rays. Though PKS1…
Uncovering the host galaxy of the -ray-emitting narrow-line Seyfert 1 galaxy FBQS J1644+2619
Filippo D'Ammando, Jose A. Acosta-Pulido, Alessandro Capetti +4
The discovery of -ray emission from radio-loud narrow-line Seyfert 1 (NLSy1) galaxies has questioned the need for large black hole masses (> 10 M) to launch relati…
Gamma-ray and Optical Oscillations of 0716+714, MRK 421, and BL Lac
A. Sandrinelli, S. Covino, A. Treves +12
We examine the 2008-2016 -ray and optical light curves of three bright BL Lac objects, 0716+714, MRK 421, BL Lac, which exhibit large structured variability. We searched for per…
