Compact objects

The discovery of fast radio bursts (FRBs) is one of the most intriguing radio astronomical discoveries of our times. FRBs are radio spikes of millisecond duration originating from cosmological distances. The nature of FRBs remains elusive, but their short duration implies a compact origin.

Active Galactic Nuclei

Supermassive accreting black holes at the center of galaxies, called Active Galactic Nuclei (AGN) are the more powerful non-transient objects in the Universe, emitting from the radio to the gamma-rays. Among them, an extreme class of AGN with a jet are the brightest one.

Combined analysis CTA plus KM3NeT

The current analysis demonstrates the successful use of multi-messenger astronomy in combination of data from two different experiments CTA and KM3NeT. There are two possible scenarios for the emission of high-energy gamma-ray sources: hadronic and leptonic. The addition of neutrino data allows us to distinguish them significantly.

Multimessenger Astronomy

Multi-messenger astronomy is astronomy based on the coordinated observation and interpretation of disparate signals. These four messengers are electromagnetic radiation, gravitational waves, neutrinos, and cosmic rays. They are created by different astrophysical processes, and thus reveal different information about their sources.
