The study of transient phenomena in a multimessenger framework will remain a major driver of astrophysical discovery in the coming decades. Supernovae, Kilonovae, compact-object formation, Novae, Gamma-ray Bursts, and tidal disruption events connect electromagnetic emission with gravitational waves and neutrinos. The key physics unfolds within minutes to hours, yet most surveys return to the...

64. Astrophysical transient search in Euclid fields

The Euclid mission, though primarily designed for cosmology, offers wide-field, high-resolution, deep, multi-wavelength imaging that makes it a powerful asset for time-domain astronomy.
While its observing strategy is not optimized for transient searches, several fields are revisited multiple times over the mission lifetime.
In these regions, difference imaging enables the discovery of...

34. Tidal disruption of a magnetized star

Tidal disruptions of stars by supermassive black holes in galactic centers (TDEs) are now being actively studied both theoretically and observationally. They are observed throughout the electromagnetic spectrum, from radio to gamma-rays. It is still unclear how the emission is produced and, in particular, what is the role of the magnetic field of the disrupted star. There are many ways how...
