A search for minute-time-scale flares from the transient AT\,2024wpp
Eran O. Ofek, Lior Ozer, Ruslan Konno +21
The AT 2018cow-like fast blue optical transient AT2022tsd showed a large number of few-minute-duration, high-luminosity (~10^43 erg/s) flares. We present an intensive search for su…
Leptohadronic Multimessenger Modeling of 324 Gamma-Ray Blazars
Xavier Rodrigues, Vaidehi S. Paliya, Simone Garrappa +3
The origin of the diffuse astrophysical neutrino flux observed by the IceCube experiment is still under debate. In recent years there have been associations of neutrino events with…
Candidate Tidal Disruption Event AT2019fdr Coincident with a High-Energy Neutrino
Simeon Reusch, Robert Stein, Marek Kowalski +46
The origins of the high-energy cosmic neutrino flux remain largely unknown. Recently, one high-energy neutrino was associated with a tidal disruption event (TDE). Here we present A…
Back from the dead: AT2019aalc as a candidate repeating TDE in an AGN
Patrik Milán Veres, Anna Franckowiak, Sjoert van Velzen +15
Context. To date, three nuclear transients have been associated with high-energy neutrino events. These transients are generally thought to be powered by tidal disruptions of stars…
Incremental Fermi Large Area Telescope Fourth Source Catalog
LAT collaboration, Soheila Abdollahi, Fabio Acero +137
We present an incremental version (4FGL-DR3, for Data Release 3) of the fourth Fermi-LAT catalog of gamma-ray sources. Based on the first twelve years of science data in the energy…
The Fourth Catalog of Active Galactic Nuclei Detected by the Fermi Large Area Telescope -- Data Release 3
LAT collaboration, Marco Ajello, Luca Baldini +100
An incremental version of the fourth catalog of active galactic nuclei (AGNs) detected by the Fermi-Large Area Telescope is presented. This version (4LAC-DR3) derives from the thir…
Observing the inner parsec-scale region of candidate neutrino-emitting blazars
Cristina Nanci, Marcello Giroletti, Monica Orienti +14
Context. Many questions on the nature of astrophysical counterparts of high-energy neutrinos remain unanswered. There is increasing evidence of a connection between blazar jets and…
A tidal disruption event coincident with a high-energy neutrino
Robert Stein, Sjoert van Velzen, Marek Kowalski +55
Cosmic neutrinos provide a unique window into the otherwise-hidden mechanism of particle acceleration in astrophysical objects. A flux of high-energy neutrinos was discovered in 20…
DmpIRFs and DmpST: DAMPE Instrument Response Functions and Science Tools for Gamma-Ray Data Analysis
Kai-Kai Duan, Wei Jiang, Yun-Feng Liang +15
GeV gamma ray is an important observation target of DArk Matter Particle Explorer (DAMPE) for indirect dark matter searching and high energy astrophysics. We present in this work a…
Multi-wavelength and neutrino emission from blazar PKS 1502+106
Xavier Rodrigues, Simone Garrappa, Shan Gao +3
In July of 2019, the IceCube experiment detected a high-energy neutrino from the direction of the powerful blazar PKS 1502+106. We perform multi-wavelength and multi-messenger mode…
Establishing accretion flares from massive black holes as a source of high-energy neutrinos
Sjoert van Velzen, Robert Stein, Marat Gilfanov +26
The origin of cosmic high-energy neutrinos remains largely unexplained. For high-energy neutrino alerts from IceCube, a coincidence with time-variable emission has been seen for th…
