X-ray polarization is a unique new probe of the particle acceleration in astrophysical jets made possible through the Imaging X-ray Polarimetry Explorer. Here we report on the firs…
A new method of reconstructing images of gamma-ray telescopes applied to the LST-1 of CTAO
CTA-LST Project, :, K. Abe +305
Imaging atmospheric Cherenkov telescopes (IACTs) are used to observe very high-energy photons from the ground. Gamma rays are indirectly detected through the Cherenkov light emitte…
Insights from the first flaring activity of a high-synchrotron-peaked blazar with X-ray polarization and VHE gamma rays
MAGIC Collaboration, K. Abe, S. Abe +250
We study a flaring activity of the HSP Mrk421 that was characterized from radio to very-high-energy (VHE; E TeV) gamma rays with MAGIC, Fermi-LAT, Swift, XMM-Newton and sever…
Ultralight Black Holes as Sources of High-Energy Particles
Michael Zantedeschi, Luca Visinelli
The \textit{memory burden} effect, the idea that the amount of information stored within a system contributes to its stabilization, is particularly relevant for systems with a larg…
Long-lived neutron-star remnants from asymmetric binary neutron star mergers: element formation, kilonova signals and gravitational waves
Sebastiano Bernuzzi, Fabio Magistrelli, Maximilian Jacobi +3
We present 3D general-relativistic neutrino-radiation hydrodynamics simulations of two asymmetric binary neutron star mergers producing long-lived neutron stars remnants and spanni…
Combined search in dwarf spheroidal galaxies for branon dark matter annihilation signatures with the MAGIC telescopes
MAGIC Collaboration
Massive brane fluctuations, called branons, behave as weakly interacting massive particles, which is one of the most favored class of candidates to fulfill the role of the dark mat…
Enhancing gravitational-wave host localization with SKYFAST: rapid volume and inclination angle reconstruction
Gabriele Demasi, Giulia Capurri, Angelo Ricciardone +3
The scientific impact of GW170817 strongly supports the need for an efficient electromagnetic follow-up campaign to gravitational-wave event candidates. The success of such campaig…
General relativistic hydrodynamic simulations of binary strange star mergers
Francesco Grippa, Aviral Prakash, Domenico Logoteta +2
We perform fully general-relativistic simulations of binary strange star mergers considering two different approaches for thermal effects. The first uses a cold equation of state (…
Probing the polarized emission from SMC X-1: the brightest X-ray pulsar observed by IXPE
Sofia V. Forsblom, Sergey S. Tsygankov, Juri Poutanen +101
Recent observations of X-ray pulsars (XRPs) performed by the Imaging X-ray Polarimetry Explorer (IXPE) have made it possible to investigate the intricate details of these objects i…
Constraints on Lorentz invariance violation from the extraordinary Mrk 421 flare of 2014 using a novel analysis method
MAGIC Collaboration, S. Abe, J. Abhir +214
The Lorentz Invariance Violation (LIV), a proposed consequence of certain quantum gravity (QG) scenarios, could instigate an energy-dependent group velocity for ultra-relativistic…
Discovery of a shock-compressed magnetic field in the north-western rim of the young supernova remnant RX J1713.7-3946 with X-ray polarimetry
Riccardo Ferrazzoli, Dmitry Prokhorov, Niccolò Bucciantini +99
Supernova remnants (SNRs) provide insights into cosmic-ray acceleration and magnetic field dynamics at shock fronts. Recent X-ray polarimetric measurements by the Imaging X-ray Pol…
Exploring non-radial oscillation modes in dark matter admixed neutron stars
Pratik Thakur, Anil Kumar, Vivek Baruah Thapa +2
Because of their extreme densities and consequently, gravitational potential, compact objects such as neutron stars can prove to be excellent captors of dark matter particles. Cons…
Dark matter admixed neutron stars with a realistic nuclear equation of state from chiral nuclear interactions
Domenico Scordino, Ignazio Bombaci
We study the effects of dark matter on the structural properties of neutron stars. In particular we investigate how the presence of a dark matter component influences the mass-radi…

Juri Poutanen, Sergey S. Tsygankov, Victor Doroshenko +108
Discovery of pulsations from a number of ULXs proved that accretion onto neutron stars can produce luminosities exceeding the Eddington limit by several orders of magnitude. The co…
