The Fermi Bubble as a Source of Cosmic Rays in the Energy Range > 10E15 eV
K. S. Cheng, D. O. Chernyshov, V. A. Dogiel +3
The {\it Fermi} Large Area Telescope has recently discovered two giant gamma-ray bubbles which extend north and south of the Galactic center with diameters and heights of the order…
Spectra and Mass Composition of Ultrahigh-Energy Cosmic Rays from Point Sources
Nikolai N. Kalmykov, Olga P. Shustova, Anna V. Uryson
We present spectra and mass composition of cosmic rays incoming to the Earth in the energy range (0.5-2)10^20 eV. As their sources we consider Seyfert galaxies located at distances…
On the collective curvature radiation
Ya. N. Istomin, A. A. Philippov, V. S. Beskin
The paper deals with the one possible mechanism of the pulsar radio emission, i.e., with the collective curvature radiation of the relativistic particle stream moving along the cur…
Fine structure in the cosmic ray spectrum: Further analysis and the next step
A. D. Erlykin, A. W. Wolfendale
An analysis is made of the fine structure in the cosmic ray energy spectrum: new facets of present observations and their interpretation and the next step. It is argued that less t…
Absorption of Gamma-Ray Photons in a Vacuum Neutron Star Magnetosphere: II. The Formation of "Lightnings"
Ya. N. Istomin, D. N. Sob'yanin
The absorption of a high-energy photon from the external cosmic gamma-ray background in the inner neutron star magnetosphere triggers the generation of a secondary electron-positro…
Absorption of Gamma-Ray Photons in a Vacuum Neutron Star Magnetosphere: I. Electron-Positron Pair Production
Ya. N. Istomin, D. N. Sob'yanin
The production of electron-positron pairs in a vacuum neutron star magnetosphere is investigated for both low (compared to the Schwinger one) and high magnetic fields. The case of…
The July 2010 outburst of the NLS1 PMN J0948+0022
L. Foschini, G. Ghisellini, L. Maraschi +23
We report about the multiwavelength campaign on the Narrow-Line Seyfert 1 (NLS1) Galaxy PMN J0948+0022 (z = 0.5846) performed in 2010 July-September and triggered by high activity…
MAGIC and Multi-Wavelength Observations of Mrk 180 and 1ES 2344+514 in 2008
S. Rügamer, E. Angelakis, D. Bastieri +14
Simultaneous multi-wavelength (MW) campaigns are the most promising approaches to investigate the still unrevealed nature of blazars, active galactic nuclei which are variable on a…
On the mean profiles of radio pulsars I: Theory of the propagation effects
V. S. Beskin, A. A. Philippov
We study the influence of the propagation effects on the mean profiles of radio pulsars using the Kravtsov-Orlov method of the wave propagation in the inhomogeneous media. This app…
Fermi-LAT Observations of Markarian 421: the Missing Piece of its Spectral Energy Distribution
LAT collaboration, A. A. Abdo et al., the MAGIC collaboration +4
We report on the gamma-ray activity of the high-synchrotron-peaked BL Lacertae object Mrk 421 during the first 1.5 years of Fermi operation, from 2008 August 5 to 2010 March 12. We…
Formation of "Lightnings" in a Neutron Star Magnetosphere and the Nature of RRATs
Ya. N. Istomin, D. N. Sobyanin
The connection between the radio emission from "lightnings" produced by the absorption of high-energy photons from the cosmic gamma-ray background in a neutron star magnetosphere a…
Gamma-ray bursts from magnetized collisionally-heated jets
Indrek Vurm, Andrei M. Beloborodov, Juri Poutanen
Jets producing gamma-ray bursts (GRBs) are likely to carry a neutron component that drifts with respect to the proton component. The neutron-proton collisions strongly heat the jet…
A fully relativistic twisted disk around a slowly rotating Kerr black hole: derivation of dynamical equations and the shape of stationary configurations
V. Zhuravlev, P. Ivanov
(abbreviated) In this paper we derive equations describing dynamics and stationary configurations of a twisted fully relativistic thin accretion disc around a slowly rotating black…
PAMELA Measurements of Cosmic-ray Proton and Helium Spectra
O. Adriani, G. C. Barbarino, G. A. Bazilevskaya +62
Protons and helium nuclei are the most abundant components of the cosmic radiation. Precise measurements of their fluxes are needed to understand the acceleration and subsequent pr…
Magnetohydrodynamic models of astrophysical jets
V. S. Beskin
In this review, analytical results obtained for a wide class of stationary axisymmetric flows in the vicinity of compact astrophysical objects are analyzed, with an emphasis on qua…

PAMELA Collaboration, O. Adriani, G. C. Barbarino +64
Precision measurements of the electron component in the cosmic radiation provide important information about the origin and propagation of cosmic rays in the Galaxy. Here we presen…
