Probing the innermost regions of AGN jets and their magnetic fields with RadioAstron. V. Space and ground millimeter-VLBI imaging of OJ 287
Jose L. Gómez, Efthalia Traianou, Thomas P. Krichbaum +27
We present the first polarimetric space VLBI observations of OJ 287, observed with RadioAstron at 22 GHz during a perigee session on 2014 April 4 and five near-in-time snapshots, t…
Scaling violation in interaction of cosmic ray hadrons and the nature of the 3 PeV knee in the spectrum of primary cosmic rays
S. Shaulov, A. Shepetov, E. Kupriyanova +2
Energy spectra of the most energetic hadrons in the core region of extensive air showers (EAS) were studied in dependence on the EAS energy in the hybrid experiment HADRON at…
RadioAstron discovery of a mini-cocoon around the restarted parsec-scale jet in 3C 84
T. Savolainen, G. Giovannini, Y. Y. Kovalev +19
We present RadioAstron space-based very long baseline interferometry (VLBI) observations of the nearby radio galaxy 3C84 (NGC1275) at the centre of the Perseus cluster. The observa…
Outflows in the presence of cosmic rays and waves with cooling
C. M. Ko, B. Ramzan, D. O. Chernyshov
Plasma outflow from a gravitational potential well with cosmic rays and self-excited Alfvén waves with cooling and wave damping is studied in the hydrodynamics regime. We study out…
MOJAVE XIX: Brightness Temperatures and Intrinsic Properties of Blazar Jets
D. C. Homan, M. H. Cohen, T. Hovatta +7
We present multi-epoch, parsec-scale core brightness temperature observations of 447 AGN jets from the MOJAVE and 2cm Survey programs at 15 GHz from 1994 to 2019. The brightness te…
Photon-axion mixing in thermal emission of isolated neutron stars
Aleksei Zhuravlev, Sergei Popov, Maxim Pshirkov
Thermally emitting neutron stars represent a promising environment for probing the properties of axion-like particles. Due to the strong magnetic fields of these sources, surface p…
The rise of muon content in extensive air showers after the 3 PeV knee of the primary cosmic ray spectrum according to data of the Tien Shan mountain installation
A. Shepetov, S. Shaulov, O. Likiy +4
We put together the experimental results on muon component of extensive air showers (EAS) which were gained with various techniques at the detector complex of the Tien Shan mountai…
On a possible origin of the gamma-ray excess around the Galactic Center
Dmitry O. Chernyshov, Andrei E. Egorov, Vladimir A. Dogiel +1
Recent observations of gamma-rays with the Fermi Large Area Telescope (LAT) in the direction of the inner Galaxy revealed a mysterious GeV excess. Its intensity is significantly ab…
Magnetic fields in the accretion disks for various inner boundary conditions
Daniela V. Boneva, Evgeny A. Mikhailov, Maria V. Pashentseva +1
The magnetic fields of accretion disks play an important role in studying their evolution. We may assume that its generation is connected to the dynamo mechanism, which is similar…
A decade of joint MOJAVE-Fermi AGN monitoring: localisation of the gamma-ray emission region
I. G. Kramarenko, A. B. Pushkarev, Y. Y. Kovalev +3
Within the MOJAVE VLBA program (Monitoring of Jets in AGN with VLBA Experiments), we have accumulated observational data at 15 GHz for hundreds of jets in -ray bright active gal…
The peculiar short-duration GRB 200826A and its supernova
A. Rossi, B. Rothberg, E. Palazzi +31
Gamma-ray bursts (GRBs) are classified as long and short events. Long GRBs (LGRBs) are associated with the end states of very massive stars, while short GRBs (SGRBs) are linked to…
Study of the 27-day variations in GCR fluxes during 2007-2008 based on PAMELA and ARINA observations
R. Modzelewska, G. A. Bazilevskaya, M. Boezio +11
Using measurements from the PAMELA and ARINA spectrometers onboard the RESURS DK-1 satellite, we have examined the 27-day intensity variations in galactic cosmic ray (GCR) proton f…
