A Proliferated Space Architecture for Time-Domain Astrophysics

Daniel Kocevski, Eric Burns, Thomas Barclay +58

Time-Domain and Multi-Messenger Astrophysics (TDAMM) is entering a discovery-rich but follow-up-limited era, creating an urgent need for responsive, multiwavelength space-based cap…

The most distant -ray flare to date: a multiwavelength campaign on the blazar GB6 B1428+4217

Andrea Gokus, Manel Errando, Ivan Agudo +12

In November 2023, the Fermi Large Area Telescope detected a -ray flare from the high-redshift blazar GB6 B1428+4217 (). We initiated a multi-wavelength follow-up campai…

A Radio-quiet AGN as a candidate counterpart to neutrino event IceCube-200615A

F. McBride, N. Schettino, J. D. O'Brien +13

Follow-up observations of neutrino events have been a promising method for identifying sources of very-high-energy cosmic rays. Neutrinos are unambiguous tracers of hadronic intera…

A gamma-ray flare from TXS 1508+572: characterizing the jet of a blazar in the early Universe

Andrea Gokus, Markus Böttcher, Manel Errando +13

Blazars can be detected from very large distances due to their high luminosity. However, the detection of -ray emission of blazars beyond has only been confirmed for a sma…

Rapid Variability of Mrk 421 During Extreme Flaring as Seen Through the Eyes of XMM-Newton

A. Gokus, J. Wilms, M. Kadler +31

By studying the variability of blazars across the electromagnetic spectrum, it is possible to resolve the underlying processes responsible for rapid flux increases, so-called flare…

The High Energy X-ray Probe (HEX-P): the most powerful jets through the lens of a superb X-ray eye

Lea Marcotulli, Marco Ajello, Markus Böttcher +20

A fraction of the active supermassive black holes at the centers of galaxies in our Universe are capable of launching extreme kiloparsec-long relativistic jets. These jets are know…

VLBI Probes of Jet Physics in Neutrino-Candidate Blazars

F. Eppel, M. Kadler, E. Ros +5

In recent years, evidence has accumulated that some high-energy cosmic neutrinos can be associated with blazars. The strongest evidence for an individual association was found in t…

The peculiar variable X-ray spectrum of the active galactic nucleus PKS 2005-489

Owen Chase, Felicia McBride, Andrea Gokus +4

PKS 2005-489 is a well-known, bright southern BL Lac object that has been detected up to TeV energies. In a low-flux state it exhibits the expected multiwavelength double-peaked sp…

Search for Gamma-Ray and Neutrino Coincidences Using HAWC and ANTARES Data

H. A. Ayala Solares, S. Coutu, D. Cowen +228

In the quest for high-energy neutrino sources, the Astrophysical Multimessenger Observatory Network (AMON) has implemented a new search by combining data from the High Altitude Wat…
