The Filling of Neutron Star Magnetospheres with Plasma: Dynamics of the Motion of Electrons and Positrons

Ya. N. Istomin, D. N. Sobyanin

We consider the motion of charged particles in the vacuum magnetospheres of rotating neutron stars with a strong surface magnetic field, B>10^(12) G. The electrons and positrons fa…

Multiwavelength monitoring of the enigmatic Narrow-Line Seyfert 1 PMN J0948+0022 in March-July 2009

LAT Collaboration, E. Angelakis, C. Bailyn +39

Following the recent discovery of gamma rays from the radio-loud narrow-line Seyfert 1 galaxy PMN J0948+0022 (z=0.5846), we started a multiwavelength campaign from radio to gamma r…

Nuclear Interaction Gamma-Ray Lines from the Galactic Center Region

V. A. Dogiel, V. Tatischeff, K. S. Cheng +3

Aims. The accretion of stars onto the central supermassive black hole at the center of the Milky Way is predicted to generate large fluxes of subrelativistic ions in the Galactic c…

Collisional mechanism for GRB emission

Andrei M. Beloborodov

Nuclear and Coulomb collisions in GRB jets create a hot electron-positron plasma. This collisional heating starts when the jet is still opaque and extends to the transparent region…

Particle Propagation in the Galactic Center and Spatial Distribution of Non-Thermal X-rays

Vladimir Dogiel, Dmitrii Chernyshov, Takayuki Yuasa +9

We showed that if the non-thermal emission from the Galactic center in the range 14-40 keV is due to inverse bremsstrahlung emission of subrelativistic protons, their interactions…

Cosmic Rays in the Disk and Halo of Galaxies

V. Dogiel, D. Breitschwerdt

We give a review of cosmic ray propagation models. It is shown that the development of the theory of cosmic ray origin leads inevitably to the conclusion that cosmic ray propagatio…

The Eas Bursts - High Energy Extensive Air Showers Correlated in Time

T. T. Barnaveli, N. A. Eristavi, I. V. Khaldeeva +2

Bursts of high energy EAS intensity (the series of EAS), following each other in short intervals of time were observed by means of Tien-Shan high mountain installation. For the low…

Fermi Discovery of Gamma-Ray Emission from NGC 1275

LAT Collaboration, A. A. Abdo, H. D. Aller +6

We report the discovery of high-energy (E>100 MeV) gamma-ray emission from NGC 1275, a giant elliptical galaxy lying at the center of the Perseus cluster of galaxies, based on obse…

Spectral Analysis of the Accretion Flow in NGC 1052 with Suzaku

L. W. Brenneman, K. A. Weaver, M. Kadler +10

We present an analysis of the 101 ks, 2007 Suzaku spectrum of the LINER galaxy NGC 1052. The 0.5-10 keV continuum is well-modeled by a power-law modified by Galactic and intrinsic…

Multiwavelength Observations of Markarian 421 in 2005 - 2006

D. Horan, V. A. Acciari, S. M. Bradbury +71

Since September 2005, the Whipple 10m Gamma-ray Telescope has been operated primarily as a blazar monitor. The five Northern Hemisphere blazars that have already been detected at t…
