High Energy Emission from Black Widows and Redbacks
Zorawar Wadiasingh, Alice K. Harding, Christo Venter +1
A large number of new black widow and redback energetic millisecond pulsars with irradiated stellar companions have been discovered through radio searches of unidentified \emph{Fer…
Polarization Signatures of Relativistic Magnetohydrodynamic Shocks in the Blazar Emission Region - I. Force-free Helical Magnetic Fields
Haocheng Zhang, Wei Deng, Hui Li +1
The optical radiation and polarization signatures in blazars are known to be highly variable during flaring activities. It is frequently argued that shocks are the main driver of t…
Role of the disk environment in the gamma-ray emission from the binary system PSR B1259-63/LS 2883
Iurii Sushch, Markus Böttcher
PSR B1259-63/LS 2883 is a very high energy (VHE; E > 100 GeV) gamma-ray emitting binary consisting of a 48 ms pulsar orbiting around a Be star with a period of 3.4 years. The Be st…
Violent Hard X-ray Variability of Mrk 421 Observed by NuSTAR in 2013 April
Vaidehi S. Paliya, Markus Bottcher, Chris Diltz +3
The well studied blazar Markarian 421 (Mrk 421, =0.031) was the subject of an intensive multi-wavelength campaign when it flared in 2013 April. The recorded X-ray and very high…
Multi-wavelength study of flaring activity in BL Lac object S5 0716+714 during 2015 outburst
Sunil Chandra, Haocheng Zhang, Pankaj Kushwaha +4
We present a detailed investigation of the flaring activity observed from a BL Lac object, S5 0716+714 , during its brightest ever optical state in the second half of January 2015.…
Discovery of variable VHE gamma-ray emission from the binary system 1FGL J1018.6-5856
H. E. S. S. Collaboration, :, A. Abramowski +230
Re-observations with the H.E.S.S. telescope array of the very-high-energy (VHE) source HESS J1018-589 A coincident with the Fermi-LAT -ray binary 1FGL J1018.6-5856 have resulted…
Studies of Relativistic Jets in Active Galactic Nuclei with SKA
Ivan Agudo, Markus Boettcher, Heino Falcke +19
Relativistic jets in active galactic nuclei (AGN) are among the most powerful astrophysical objects discovered to date. Indeed, jetted AGN studies have been considered a prominent…
Hadronic models of blazars require a change of the accretion paradigm
Andrzej A. Zdziarski, Markus Boettcher
We study hadronic models of broad-band emission of jets in radio-loud active galactic nuclei, and their implications for the accretion in those sources. We show that the models tha…
