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. Martí +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…

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…

The physical properties of candidate neutrino-emitter blazars

Alessandra Azzollini, Sara Buson, Alexis Coleiro +5

The processes governing the production of astrophysical high-energy neutrinos are still debated, and the sources originating them remain an open question. Among the putative emitte…

Combined dark matter search towards dwarf spheroidal galaxies with Fermi-LAT, HAWC, H.E.S.S., MAGIC, and VERITAS

LAT Collaboration, S. Abdollahi, L. Baldini +586

Dwarf spheroidal galaxies (dSphs) are excellent targets for indirect dark matter (DM) searches using gamma-ray telescopes because they are thought to have high DM content and a low…

Dynamic and Radiative Implications of Jet-Star Interactions in AGN Jets

Gaëtan Fichet de Clairfontaine, Manel Perucho, José María Martí +1

The interactions between jets from active galactic nuclei (AGN) and their stellar environments significantly influence jet dynamics and emission characteristics. In low-power jets,…
