Constraints on the VHE counterpart of two binary black hole mergers observed by the MAGIC and CTAO LST-1 telescopes
K. Abe, S. Abe, J. Abhir +358
We present very-high-energy gamma-ray observations of two binary black hole merger candidates, GW240615_113620 and GW241125_010116, performed with the Major Atmospheric Gamma Imagi…
SN 2022erq: A Superluminous Thermonuclear Supernova with Escalating Preexplosion Mass Loss
Qian Zhai, Jujia Zhang, Xiaofeng Wang +51
We present a photometric and spectroscopic study of the superluminous Type Ia supernova SN 2022erq. Its early spectra, dominated by iron-group elements with weak intermediate-mass…
Magnetospheric flows in X-ray pulsars II: Heating, cooling and ionization degree at sub-critical accretion
Alexander A. Mushtukov, Alexander Y. Potekhin, Valery F. Suleimanov +2
Magnetospheric accretion flows in X-ray pulsars shape their spectra, polarization, and variability. We model the thermal balance of the flow enveloping the neutron star magnetosphe…
X-Ray Polarization from the Atoll 4U 1735-44 Suggests a Low Inclination
M. A. Díaz Teodori, A. Bobrikova, A. Gnarini +17
X-ray polarimetry is a new tool capable of probing the geometry of accretion onto weakly magnetized neutron stars. Here we present the first X-ray spectropolarimetric results from…
A Ring of Fire Orphan γ-Ray Flare in the Neutrino Candidate 3C 120
E. Traianou, G. Bruni, J. Rodi +7
We present 43\,GHz VLBI observations of the radio galaxy 3C~120 during its brightest -ray outburst (March 2018), recently associated with the IceCube neutrino alert IC-180213A.…
Chasing Gamma-Ray Signals from Binary Neutron Star Coalescences with the Cherenkov Telescope Array: Prospects and Observing Strategies
S. Abe, J. Abhir, A. Abhishek +457
The detection of gravitational waves (GWs) from a binary neutron star (BNS) merger by Advanced LIGO and Advanced Virgo (GW170817), together with its electromagnetic counterpart, th…
