Discovery of a Radiation Component from the Vela Pulsar Reaching 20 Teraelectronvolts
The H. E. S. S. Collaboration, :, F. Aharonian +178
Gamma-ray observations have established energetic isolated pulsars as outstanding particle accelerators and antimatter factories in the Galaxy. There is, however, no consensus rega…
Neural Network Analysis of S-Star Dynamics: Implications for Modified Gravity
N. Galikyan, Sh. Khlghatyan, A. A. Kocharyan +1
We studied the dynamics of S-stars in the Galactic center using the physics-informed neural networks. The neural networks are considered for both, Keplerian and the General Relativ…
Joint searches by FACT, H.E.S.S., MAGIC and VERITAS for VHE gamma-ray emission associated with neutrinos detected by IceCube
Fabian Schüssler, Halim Ashkar, Elisa Bernardini +11
The sources of the astrophysical flux of high-energy neutrinos detected by IceCube are still largely unknown, but searches for temporal and spatial correlation between neutrinos an…
Cosmic voids and the kinetic analysis. III. Hubble tension and structure formation in the late Universe
V. G. Gurzadyan, N. N. Fimin, V. M. Chechetkin
We study structure formation in the late Universe within the Vlasov kinetic self-consistent field approach. Our work is principally focused on the use of the modified gravitational…
Line profile of nuclear de-excitation gamma-ray emission from very hot plasma
Hiroki Yoneda, Felix Aharonian, Paolo Coppi +2
De-excitation gamma-ray lines, produced by nuclei colliding with protons, provide information about astrophysical environments where particles have kinetic energies of MeV…
tilepy: rapid tiling strategies in mid/small FoV observatories
Fabian Schüssler, Halim Ashkar, Mathieu de Bony de Lavergne +1
The challenges inherent to time-domain multi-messenger astronomy require strategic actions so that adapted, optimized follow-up observations are performed efficiently. In particula…
