Radio pulsars with expected gamma radiation and gamma pulsars as pulsating radio emitters
I. F. Malov, M. A. Timirkeeva
Pulsars play a crucial astrophysical role as the highly energetic compact radio, X-ray, and gamma-ray sources. Our previous works show that the radio pulsars found as the pulsing g…
Targeted millisecond pulsar surveys of Fermi gamma-ray sources with LOFAR
C. G. Bassa, Z. Pleunis, J. W. T. Hessels +7
We have used LOFAR to perform targeted millisecond pulsar surveys of Fermi gamma-ray sources. Operating at a center frequency of 135 MHz, the surveys use a novel semi-coherent dedi…
Study of cosmic ray sources using data on extragalactic diffuse gamma-ray emission
A. Uryson
We discuss ultra-high energy (UHE) cosmic rays (CR) from minor sources and their possible contribution to the extragalactic diffuse gamma-ray emission. As an illustration of minor…
On the internal structure of the current sheet in the pulsar wind
V. V. Prokofev, L. I. Arzamasskiy, V. S. Beskin
We investigate the internal structure of the current sheet in the pulsar wind within force-free and two-fluid MHD approximations. Within the force-free approximation we obtain gene…
Detectability of dark matter subhalos by means of the GAMMA-400 telescope
A. E. Egorov, A. M. Galper, N. P. Topchiev +4
We investigated the detectability of Galactic subhalos with masses formed by annihilating WIMP dark matter by the planned GAMMA-400 gamma-ray telescope. The…
Resolving the emission regions of the Crab pulsar's giant pulses
Robert Main, Rebecca Lin, Marten H. van Kerkwijk +5
The Crab pulsar has striking radio emission properties, with the two dominant pulse components -- the main pulse and the interpulse -- consisting entirely of giant pulses. The emis…
Jet in jet in M87
Denis Nikolaevich Sob'yanin
New high-resolution Very Long Baseline Interferometer observations of the prominent jet in the M87 radio galaxy show a persistent triple-ridge structure of the transverse 15-GHz pr…
The Possibility of Investigating Ultra-High-Energy Cosmic-Ray Sources Using Data on the Extragalactic Diffuse Gamma-Ray Emission
A. V. Uryson
We provide our estimates of the intensity of the gamma-ray emission with an energy near 0.1 TeV generated in inrergalactic space in the interactions of cosmic rays with background…
On the radiation beaming of bright X-ray pulsars and constraints on neutron star mass-radius relation
Alexander A. Mushtukov, Patrick A. Verhagen, Sergey S. Tsygankov +3
The luminosity of accreting magnetised neutron stars can largely exceed the Eddington value due to appearance of accretion columns. The height of the columns can be comparable to t…
MOJAVE - XIV. Shapes and opening angles of AGN jets
A. B. Pushkarev, Y. Y. Kovalev, M. L. Lister +1
We present 15 GHz stacked VLBA images of 373 jets associated with active galactic nuclei (AGN) having at least five observing epochs within a 20 yr time interval 1994-2015 from the…
On the acceleration and deceleration of relativistic jets in active galactic nuclei - II. Mass-loading
E. E. Nokhrina, V. S. Beskin
The effect of a mass-loading of the magnetohydrodynamic (MHD) flow in a relativistic jet from active galactic nuclei (AGN) due to conversion is considered an…
On the mean profiles of radio pulsars II: Reconstruction of complex pulsar light-curves and other new propagation effects
Hayk Hakobyan, Vasily Beskin, Alexander Philippov
Our previous paper outlined the general aspects of the theory of radio light curve and polarization formation for pulsars. We predicted the one-to-one correspondence between the ti…
Observational consequences of optical band milliarcsecond-scale structure in active galactic nuclei discovered by Gaia
Leonid Petrov, Yuri Y. Kovalev
We interpret the recent discovery of a preferable VLBI/Gaia offset direction for radio-loud active galactic nuclei (AGNs) along the parsec-scale radio jets as a manifestation of th…
Secondary positrons and electrons measured by PAMELA experiment
V. V. Mikhailov, O. Adriani, G. Barbarino +55
We present a measurements of electron and positron fluxes below the geomagnetic cutoff rigidity in wide energy range from 50 MeV to several GeV by the PAMELA magnetic spectrometer.…
Origin of X-ray and gamma-ray emission from the Galactic central region
D. O. Chernyshov, K. -S. Cheng, V. A. Dogiel +1
We study a possible connection between different non-thermal emissions from the inner few parsecs of the Galaxy. We analyze the origin of the gamma-ray source 2FGL J1745.6-2858 (or…
A Search for Fast Radio Bursts with the GBNCC Pulsar Survey
P. Chawla, V. M. Kaspi, A. Josephy +17
We report on a search for Fast Radio Bursts (FRBs) with the Green Bank Northern Celestial Cap (GBNCC) Pulsar Survey at 350 MHz. Pointings amounting to a total on-sky time of 61 day…
Parsec-scale Faraday rotation and polarization of 20 active galactic nuclei jets
E. V. Kravchenko, Y. Y. Kovalev, K. V. Sokolovsky
We perform polarimetry analysis of 20 active galactic nuclei (AGN) jets using the Very Long Baseline Array (VLBA) at 1.4, 1.6, 2.2, 2.4, 4.6, 5.0, 8.1, 8.4, and 15.4 GHz. The study…
