Euclid: Quick Data Release (Q1) -- Optical hotspots in powerful radio galaxies
M. J. Hardcastle, L. Bisigello, M. Bondi +154
The hotspots of powerful radio galaxies are the sites of high-energy particle acceleration, but radio observations give us limited information on the electron energy distributions…
HESS J1831098 -- Exploring a pulsar halo scenario with H.E.S.S. data
Karim Sabri, Yves Gallant, Justine Devin +1
Pulsar halos are a class of extended very-high-energy (VHE) sources highlighted by the HAWC observatory towards the Geminga pulsar and PSR B065614. These VHE sources are interpr…
Constraining gamma-ray burst parameters with the first ultra-high energy neutrino event KM3-230213A
KM3NeT Collaboration, O. Adriani, A. Albert +278
Context: The detection of the highest energy neutrino observed to date by KM3NeT, with an estimated energy of 220 PeV, opens up new possibilities for the study and identification o…
Multi-wavelength study of OT 081: broadband modelling of a transitional blazar
MAGIC Collaboration, H. Abe, S. Abe +270
OT 081 is a well-known, luminous blazar that is remarkably variable in many energy bands. We present the first broadband study of the source which includes very-high-energy (VHE, $…
Limit on intergalactic magnetic field from ultra-high-energy cosmic ray hotspot in Perseus-Pisces region
Andrii Neronov, Dmitri Semikoz, Oleg Kalashev
Telescope Array collaboration has reported an evidence for existence of a source of ultra-high-energy cosmic ray (UHECR) events in Perseus-Pisces supercluster. We show that the mer…
Researching of magnetic cutoff for local sources of charged particles in the halo of the Galaxy
M. Yu. Khlopov, A. O. Kirichenko, A. G. Mayorov
Models of highly inhomogeneous baryosynthesis of the baryonic asymmetric Universe allow for the existence of macroscopic domains of antimatter, which could evolve in a globular clu…
Southern African Large Telescope Spectroscopy of BL Lacs for the CTA project
E. Kasai, P. Goldoni, M. Backes +14
In the last two decades, very-high-energy gamma-ray astronomy has reached maturity: over 200 sources have been detected, both Galactic and extragalactic, by ground-based experiment…
Unidentified Gamma-Ray Sources as Ancient Pulsar Wind Nebulae
O. C. de Jager, S. E. S. Ferreira, A. Djannati-Ataï +6
In this paper we explore the evolution of a PWN while the pulsar is spinning down. An MHD approach is used to simulate the evolution of a composite remnant. Particular attention is…
