AGN Jets from Formation to Dissipation
A. -K. Baczko, Eleni Vardoulaki, Etienne Bonnassieux +26
Active Galactic Nuclei (AGN) are among the most energetic phenomena in the Universe, capable of launching powerful relativistic jets that extend from sub-parsec to megaparsec scale…
Stellar mass loading drives dissipation and reacceleration in AGN jets: Explaining VLBI-Gaia offsets and constraining jet power
G. Fichet de Clairfontaine, M. Perucho, J. M. Martà +1
Recent Very Long Baseline Interferometry (VLBI) and Gaia astrometry reveal systematic milliarcsecond-scale offsets between the radio and optical centroids of active galactic nuclei…
Jet-red giant interactions as a source of extragalactic neutrinos: Insights from KM3-230213A
G. Fichet de Clairfontaine, M. Perucho, J. M. MartÃ
The production sites of high-energy astrophysical neutrinos remain uncertain, though growing evidence suggests a connection to relativistic jets in active galactic nuclei (AGN). We…
Relativistic hydrodynamics simulations of supernova explosions within extragalactic jets
B. Longo, M. Perucho, V. Bosch-Ramon +2
Jets in active galactic nuclei have to cross significant distances within their host galaxies, meeting large numbers of stars of different masses and evolution stages in their path…
AGN hosting jets. I: A semi-analytical model for the evolution of radio galaxies
Pau Beltrán-Palau, Manel Perucho, José MarÃa MartÃ
Three-dimensional simulations of relativistic jets are a useful tool to understand the evolution of jets and radio galaxies in detail. However, computationally demanding as they ar…
Unprecedentedly bright X-ray flaring in Cygnus X-1 observed by INTEGRAL
P. Thalhammer, T. Bouchet, J. Rodriguez +15
We study three extraordinarily bright X-ray flares originating from Cyg X-1 seen on 2023 July 10 detected with INTEGRAL. The flares had a duration on the order of only ten minutes…
