We present a description of the new complex installation for the study of extensive air showers which was created at the Tien Shan mountain cosmic ray station, as well as the resul…
Underground neutron events at Tien Shan and the properties of the eV EAS muonic component
A. Shepetov, A. Chubenko, O. Kryakunova +13
The events of multiple neutron production under 2000g/cm thick rock absorber were studied at the Tien~Shan mountain cosmic ray station, at the altitude of 3340m above the sea l…
Measurements of the low energy neutron and gamma ray accompaniment of extensive air showers in the knee region of primary cosmic ray spectrum
A. Shepetov, A. Chubenko, B. Iskhakov +12
Purposeful investigation of radiation fluxes strongly delayed in relation to the main particles front of extensive air shower (EAS) was undertaken at the Tien Shan Mountain Cosmic…
On the Radio Image of Relativistic Jets -- I. Internal Structure, Doppler Boosting, and Polarization Maps
A. V. Chernoglazov, V. S. Beskin, V. I. Pariev
In this first paper from forthcoming series of works devoted to radio image of relativistic jets from active galactic nuclei the role of internal structure of a flow is discussed.…
Identifying nearby sources of ultra-high-energy cosmic rays with deep learning
Oleg Kalashev, Maxim Pshirkov, Mikhail Zotov
We present a method to analyse arrival directions of ultra-high-energy cosmic rays (UHECRs) using a classifier defined by a deep convolutional neural network trained on a HEALPix g…
Consequences of Energetic Magnetar-Like Outbursts of Nearby Neutron Stars: C Events and the Cosmic Electron Spectrum
F. Y. Wang, Xinyu Li, D. O. Chernyshov +3
Four significant events of rapid C increase have taken place within the past several thousand years. The physical origin of these rapid increases is still a mystery but must…
Deep XMM-Newton observations of the northern disk of M31 II: Tracing the hot interstellar medium
Patrick J. Kavanagh, Manami Sasaki, Dieter Breitschwerdt +10
Aims: We use new deep XMM-Newton observations of the northern disk of M 31 to trace the hot interstellar medium (ISM) in unprecedented detail and to characterise the physical prope…
A LOFAR census of non-recycled pulsars: extending below 80 MHz
A. V. Bilous, L. Bondonneau, V. I. Kondratiev +9
We present the results from the low-frequency (40--78 MHz) extension of the first LOFAR pulsar census of non-recycled pulsars. We have used the Low-Band Antennas of the LOFAR core…
The Green Bank North Celestial Cap Pulsar Survey. V. Pulsar Census and Survey Sensitivity
Alexander McEwen, Renee Spiewak, Joseph Swiggum +23
The Green Bank North Celestial Cap (GBNCC) pulsar survey will cover the entire northern sky () at 350 MHz, and is one of the most uniform and sensitive all-sky pulsar…
Relativistic polytrope from the collimation and acceleration profiles of the M87 jet at subparsec scales and thermodynamic evidence for the Blandford-Znajek mechanism
Denis Nikolaevich Sob'yanin
Recent Very Long Baseline Interferometry observations of the relativistic jet in the M87 radio galaxy at 43 GHz show gradual relativistic acceleration of the plasma and suggest a l…
Progressive steepening of the SNR RX J1713.7-3946 X-ray spectrum from XMM-Newton to INTEGRAL
Ekaterina Kuznetsova, Roman Krivonos, Eugene Churazov +2
In this work, we present the first detailed analysis of the supernova remnant RX J1713.7-3946 in the hard X-ray energy range with the IBIS coded-mask telescope on board the INTEGRA…
Origin of gamma-ray families accompanied by halos and detected in experiments with x-ray emulsion chambers
V. S. Puchkov, S. E. Pyatovsky
The phenomenon of gamma-ray families featuring halos that is observed in an experiment with x-ray emulsion chambers (XREC) in the Pamir experiment and in other XREC experiments is…
Extragalactic cosmic ray sources with very small contribution in the particle flux on the Earth and their study
A. Uryson
Possible existence of extragalactic ultra-high energy cosmic ray sources giving a very small particle flux on the Earth is considered. Accretion discs around supermassive black hol…
Penetrating component in cosmic rays
Sergey Shaulov
We present a study of the high energy spectra of hadrons in cores of extensive air showers. These data were obtained for the first time in the hybrid {\it HADRON} experiment (Tien-…
Search for isolated Galactic Centre stellar mass black holes in the IR and sub-mm range

We investigate a possibility to find an accreting isolated black hole (IBH) with mass within Central Galactic Molecular Zone (CMZ) in the submillimetre a…
M87 black hole mass and spin estimate through the position of the jet boundary shape break
E. E. Nokhrina, L. I. Gurvits, V. S. Beskin +3
We propose a new method of estimating a mass of a super massive black hole residing in the center of an active galaxy. The active galaxy M87 offers a convenient test case for the m…
