Hot accretion flows in low-luminosity active galactic nuclei in NGC 4258 and NGC 7213
Michal Szanecki, Andrzej Niedzwiecki, Rafal Wojaczynski
We study the high energy emission of two active galactic nuclei (AGN), NGC 4258 and NGC 7213. We directly apply the general-relativistic (GR) hot flow model, kerrflow, to the archi…
KM3NeT/ARCA expectations in view of a novel multimessenger study of starburst galaxies
Antonio Marinelli, Antonio Ambrosone, Walid Idrissi Ibnsalih +4
Starburst galaxies (SBGs) and more in general starforming galaxies represent a class of galaxies with a high star formation rate (up to 100 solar masses/year). Despite their low lu…
The X/gamma-ray correlation in NGC 4945 and the nature of its gamma-ray source
Rafal Wojaczynski, Andrzej Niedzwiecki
We report hints for the correlation between the X-ray and gamma-ray emission in the nearby galaxy NGC 4945, which harbors both an active galactic nucleus and a nuclear starburst re…
Fermi-LAT Upper Limit for NGC 4151 and its Implications for Physics of Hot Accretion Flow
Rafal Wojaczynski, Andrzej Niedzwiecki, Fu-Guo Xie
We present preliminary results of our analysis of the {\it Fermi}-LAT data from the direction of NGC 4151. We find a new gamma-ray source with a statistical significance sigma > 5,…
