Light bridges are elongated and bright structures protruding into the umbra of sunspots. The presence of light bridges has a significant role in the evolution...

Early-type galaxies (ETGs) were historically considered as ‘boring’ objects by astronomers. This galaxy category encompasses lenticular and elliptical galaxies...

Umbral flashes are sudden brightenings commonly visible in the core of some chromospheric lines. Theoretical and numerical modeling suggests that they are...

During the final stages of their lives, stars with masses between one and eight times the mass of the Sun evolve along the asymptotic giant branch (AGB). AGB...

The black holes at the centres of galaxies are the most mysterious objects in the Universe, not only because of the huge quantities of material within them...

Red dwarfs are the most common stars in the galaxy. In recent years they have become key targets in the search for exoplanets. These stars are usually...

The transient Swift J1727.8-162 is the latest member of the X-ray binary black hole family to be discovered. They are formed by a black hole and a low-mass star...

We present the results of our spatially resolved investigation into the interplay between the ages of the stellar populations and the kinematics of the warm...
