Sub-GeV Gamma Rays from Nearby Seyfert Galaxies and Implications for Coronal Neutrino Emission
Kohta Murase, Christopher M. Karwin, Shigeo S. Kimura +2
Recent observations of high-energy neutrinos by IceCube and gamma rays by the Fermi Large Area Telescope (LAT) and the MAGIC telescope have suggested that neutrinos are produced in…
TELAMON: Effelsberg Monitoring of AGN Jets with Very-High-Energy Astroparticle Emissions -- Polarization properties
J. Heßdörfer, M. Kadler, P. Benke +33
We present recent results of the TELAMON program, which is using the Effelsberg 100-m telescope to monitor the radio spectra of active galactic nuclei (AGN) under scrutiny in astro…
Hadronic processes at work in 5BZB J0630-2406
Gaëtan Fichet de Clairfontaine, Sara Buson, Leonard Pfeiffer +6
Recent observations are shedding light on the important role that active galactic nuclei (AGN) play in the production of high-energy neutrinos. In this study, we focus on one objec…
Constraining the PG 1553+113 binary hypothesis: interpreting hints of a new, 22-year period
Sagar Adhikari, Pablo Penil, John Ryan Westernacher-Schneider +5
PG 1553+113 is a well-known blazar exhibiting evidence of a -yr quasi-periodic oscillation (QPO) in radio, optical, X-ray, and -ray bands. Since QPO mechanisms often…
Extragalactic neutrino factories
Sara Buson, Andrea Tramacere, Lenz Oswald +6
Identifying the astrophysical sources responsible for the high-energy cosmic neutrinos has been a longstanding challenge. In a previous work, we report evidence for a spatial corre…
Fermi-GBM Discovery of GRB 221009A: An Extraordinarily Bright GRB from Onset to Afterglow
S. Lesage, P. Veres, M. S. Briggs +136
We report the discovery of GRB 221009A, the highest flux gamma-ray burst ever observed by the Fermi Gamma-ray Burst Monitor (GBM). This GRB has continuous prompt emission lasting m…
