AT2025agpz in Rubin commissioning data: distinguishing a luminous interacting supernova from nuclear transients in compact galaxies

C. R. Angus, M. Quilt, H. F. Stevance +37

The Vera C. Rubin Observatory's Legacy Survey of Space and Time will discover unprecedented numbers of rare, long-lived optical transients, many of which will be too faint or too n…

Bayesian parameter study of the Seyfert-starburst composite galaxies NGC 1068 and NGC 7469

Björn Eichmann, Silvia Salvatore, Santiago del Palacio +4

Multimessenger observation of the Seyfert-starburst composite galaxies NGC 1068 and NGC 7469 indicate a characteristic feature in the radio band (the so-called mm-bump) as well as…

An Extremely Luminous Flare Recorded from a Supermassive Black Hole

Matthew J. Graham, Barry McKernan, K. E. Saavik Ford +17

Since their discovery more than 60 years ago, accreting supermassive black holes in active galactic nuclei (AGN) were recognized as highly variable sources, requiring an extremely…

Monte Carlo parameter study for Seyfert AGN-starburst composite galaxies NGC1068 and NGC7469

Silvia Salvatore, Björn Eichmann, Giacomo Sommani +3

Seyfert-starburst composite galaxies host two promising phenomena of non-thermal high-energy radiation. In this regard the IceCube observation of high-energy neutrinos from the dir…

The La Silla Schmidt Southern Survey

Adam A. Miller, Natasha S. Abrams, Greg Aldering +75

We present the La Silla Schmidt Southern Survey (LS4), a new wide-field, time-domain survey to be conducted with the 1 m ESO Schmidt telescope. The 268 megapixel LS4 camera mosaics…

Characterizing Candidate Blazar Counterparts of the Ultra-High-Energy Event KM3-230213A

KM3NeT Collaboration, MessMapp Group, LAT Collaboration +13

High-energy astrophysical neutrinos serve as crucial messengers for understanding hadronic acceleration processes and identifying the origins of cosmic rays, with blazars among the…

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…

Flaires: A Comprehensive Catalog of Dust-Echo-like Infrared Flares

Jannis Necker, Eleni Graikou, Marek Kowalski +5

Context: Observations of transient emission from extreme accretion events onto supermassive black holes can reveal conditions in the center of galaxies and the black hole itself. M…

European VLBI Network observations of the peculiar radio source 4C 35.06 overlapping with a compact group of nine galaxies

Patrik Milán Veres, Krisztina Éva Gabányi, Sándor Frey +8

Context. According to the hierarchical structure formation model, brightest cluster galaxies (BCGs) evolve into the most luminous and massive galaxies in the Universe through multi…

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…
