A Very-High-Energy Gamma-Ray View of the Transient Sky
DOI: 10.3390/universe10040163 Bibcode: 2024Univ...10..163C

Carosi, Alessandro; López-Oramas, Alicia

The development of the latest generation of Imaging Atmospheric Cherenkov Telescopes (IACTs) over recent decades has led to the discovery of new extreme astrophysical phenomena in the very-high-energy (VHE, E > 100 GeV) gamma-ray regime. Time-domain and multi-messenger astronomy are inevitably connected to the physics of transient VHE emitters,…

High-Energy Spectra of Black Hole and Neutron Star Low-Mass X-Ray Binaries
DOI: 10.3390/universe10120446 Bibcode: 2024Univ...10..446P

Pszota, Gábor

In the case of low-mass X-ray binaries, the companion star is often too faint for detection; therefore, there is no chance for dynamical studies to independently determine the mass of the compact object. In the absence of a mass estimate, one cannot make a distinction as to whether the binary hosts a black hole or neutron star. Therefore, the ques…

3C 120 Disk/Corona vs. Jet Variability in X-rays
DOI: 10.3390/universe9050212 Bibcode: 2023Univ....9..212F

Fedorova, Elena; Del Popolo, Antonio

The 3C120 (Mrk 1506, UGC 03087, Mrk 9014) is a type 1 Seyfert (Sy1)/broad-line radio galaxy (BLRG) with intriguing variable jet activity featuring "dip" and "outburst" phases. Significant X-ray observational datasets have been collected for 3C120 by INTEGRAL, XMM-Newton, SWIFT, Suzaku, and other X-ray observational facilities. The overall X-ray sp…

Multiwavelength Observations of Fast Radio Bursts
DOI: 10.3390/universe7030076 Bibcode: 2021Univ....7...76N

Zampieri, Luca; Turatto, Massimo; Nicastro, Luciano +3 more

The origin and phenomenology of the Fast Radio Burst (FRB) remains unknown despite more than a decade of efforts. Though several models have been proposed to explain the observed data, none is able to explain alone the variety of events so far recorded. The leading models consider magnetars as potential FRB sources. The recent detection of FRBs fr…

INTEGRAL View of TeV Sources: A Legacy for the CTA Project
DOI: 10.3390/universe7050135 Bibcode: 2021Univ....7..135M

Ubertini, Pietro; Bazzano, Angela; Bird, Antony J. +7 more

Investigations that were carried out over the last two decades with novel and more sensitive instrumentation have dramatically improved our knowledge of the more violent physical processes taking place in galactic and extra-galactic Black-Holes, Neutron Stars, Supernova Remnants/Pulsar Wind Nebulae, and other regions of the Universe where relativi…
