Intrinsic Physical Conditions and Structure of Relativistic Jets in Active Galactic Nuclei
E. E. Nokhrina, V. S. Beskin, Y. Y. Kovalev +1
The analysis of the frequency dependence of the observed shift of the cores of relativistic jets in active galactic nuclei (AGN) allows us to evaluate the number density of the out…
Rotation Measures in AGN jets seen by VLA at 21 cm to 6 mm
E. V. Kravchenko, W. D. Cotton, Y. Y. Kovalev
We present Faraday Rotation Measure (RM) properties of seven active galactic nuclei (AGN), observed with the NRAO VLA at three epochs in 2012-2014. Data was taken at 1.4, 2.2, 5.0,…
The Shapes of Pulsar Radio Pulses in the Plane of the Sky
H. L. Hakobyan, V. S. Beskin
The sizes of pulsar radio pulses in the plane of the sky are determined. This is important not only in relation to the possibility of directly resolving the radio pulses spatially,…
Properties of flat-spectrum radio-loud Narrow-Line Seyfert 1 Galaxies
L. Foschini, M. Berton, A. Caccianiga +27
We have conducted a multiwavelength survey of 42 radio loud narrow-1ine Seyfert 1 galaxies (RLNLS1s), selected by searching among all the known sources of this type and omitting th…
Measurement of boron and carbon fluxes in cosmic rays with the PAMELA experiment
O. Adriani, G. C. Barbarino, G. A. Bazilevskaya +61
The propagation of cosmic rays inside our galaxy plays a fundamental role in shaping their injection spectra into those observed at Earth. One of the best tools to investigate this…
Chandra detection of a new diffuse X-ray component from the globular cluster 47 Tucanae
E. M. H. Wu, C. Y. Hui, A. K. H. Kong +3
In re-analyzing the archival Chandra data of the globular cluster 47 Tucanae, we have detected a new diffuse X-ray emission feature within the half-mass radius of the cluster. The…
Cosmic rays and changes in atmospheric infra-red transmission
A. D. Erlykin, T. Sloan, A. W. Wolfendale
Recent work by Aplin and Lockwood [1] was interpreted by them as showing that there is a multiplying ratio of order 10 for the infra-red energy absorbed in the ionization pr…
Effects of the Angular Momentum of Accreting Matter on the Flow Structure in the Subsonic Settling and Bondi-Hoyle Accretion Regimes
L. I. Arzamasskiy, V. S. Beskin
Previously unexplored accretion regimes associated with the rotation of accreting matter, namely the perturbations of a quasi-spherical subsonic settling flow and Bondi-Hoyle accre…
Emission from the Galaxy NGC 1275 at High and Very High Energies and its Origin
V. G. Sinitsyna, V. Yu. Sinitsyna
The Seyfert galaxy NGC 1275 is the central, dominant galaxy in the Perseus cluster of galaxies. NGC1275 is known as a powerful source of radio and X-ray emission. The well-known ex…
Two active states of the narrow-line gamma-ray-loud AGN GB 1310+487
K. V. Sokolovsky, F. K. Schinzel, Y. T. Tanaka +49
Previously unremarkable, the extragalactic radio source GB 1310+487 showed a gamma-ray flare on 2009 November 18, reaching a daily flux of ~10^-6 photons/cm^2/s at energies E>100 M…
