Ring Asymmetry and Spin in M87*
Vadim Bernshteyn, Nicholas S. Conroy, Michi Bauböck +263
Event Horizon Telescope (EHT) images of the supermassive black hole M87* depict an asymmetric ring of emission. General relativistic magnetohydrodynamic (GRMHD) models of M87* and…
Probing jet base emission of M87* with the 2021 Event Horizon Telescope observations
Saurabh, Hendrik Müller, Sebastiano D. von Fellenberg +282
We investigate the presence and spatial characteristics of the jet base emission in M87* at 230 GHz, enabled by the enhanced uv coverage in the 2021 Event Horizon Telescope (EHT) o…
Optimizing the potential of KM3NeT in detecting core-collapse supernovae
KM3NeT Collaboration, O. Adriani, A. Albert +285
Core-collapse supernovae mark the end of life of massive stars. However, despite their importance in astrophysics, their underlying mechanisms remain unclear. Neutrinos that emerge…
Multi-messenger flare in the quasar PKS 0446+11
Y. Y. Kovalev, M. F. Aller, A. K. Erkenov +15
The physical mechanisms driving neutrino and electromagnetic flares in blazars remain poorly understood. We investigate a prominent multi-messenger flare in the quasar PKS 1424+240…
Dim cores of radio-bright AGN jets: VLBI and Gaia astrometry pinpoint different parsec-scale features
A. V. Popkov, Y. Y. Kovalev, A. V. Plavin +2
Astrometry with the very long baseline radio interferometry (VLBI) allows to determine the position of a point close to the source's brightest compact detail at milliarcsecond scal…
Looking into the Jet Cone of the Neutrino-Associated Very High Energy Blazar PKS 1424+240
Y. Y. Kovalev, A. B. Pushkarev, J. L. Gomez +7
The acceleration process of massive particles as well as the production of very high energy (VHE) photons and neutrinos remains a fundamental challenge in astrophysics. We investig…
