The discovery of high-energy astrophysical neutrinos and the first hints of coincident
electromagnetic and neutrino emissions opened new opportunities in multi-messenger …

The detection of an astrophysical flux of neutrinos in the TeV–PeV energy range by the
IceCube Neutrino Observatory has opened new possibilities for the study of extreme cosmic …

We report on multiwavelength target-of-opportunity observations of the blazar PKS 0735+
178, located 2 fdg 2 away from the best-fit position of the IceCube neutrino event IceCube …

Abstract The Zwicky Transient Facility follow-up campaign of alerts released by the IceCube
Neutrino Observatory has led to the likely identification of the transient AT2019fdr as the …

Mounting evidence suggests that luminous fast blue optical transients (LFBOTs) are
powered by a compact object, launching an asymmetric and fast outflow responsible for the …

Active galactic nuclei (AGN) with relativistic jets are the most powerful persistent
astrophysical sources of electromagnetic radiation in the Universe. Blazars are the most …

The exact sources of high-energy neutrinos detected by the IceCube neutrino observatory
still remain a mystery. For the first time, this work explores the hypothesis that galaxy …

With the advent of time-domain astronomy and the game-changing next generation of
telescopes, we have unprecedented opportunities to explore the most energetic events in …

The observation of electromagnetic counterparts to both high energy neutrinos and
gravitational waves marked the beginning of a new era in astrophysics. The multi …

The detection of a diffuse background of astrophysical neutrinos with the IceCube Neutrino
Observatory in 2013 opened a new window to the sky [1, 2]. Neutrinos are unambiguous …
