Disks in spiral galaxies consist of stars and gas. The stellar disks show radially an exponential surface brightness distribution (and vertically one resembling...

The amount of data available in image guided medical interventions and surgeries is growing at a rapid rate. More data per device and more devices present...

The Twinkle Space Mission is a space-based observatory that has been conceived to measure the atmospheric composition of exoplanets, stars and solar system...

We review some ideas and facts and disputes related to the research about the stellar density distribution in the Galactic bulge in the last decades: the...

While ultraluminous supersoft X-ray sources (ULSs) bear features for intermediate mass black holes or very massive white dwarfs possibly close to Chandrasekhar...

Large-scale outflows from galaxies are a crucially important yet poorly understood aspect of galaxy evolution. They redistribute gas and metals into the IGM...

An analysis of the impact of seismic and volcanic activity was carried out at selected astronomical sites, namely the observatories of El Teide (Tenerife...

The interaction of galaxies with their environment is a crucial issue to understand their formation and evolution. A huge effort has been devoted, from...

The fueling of black holes occurring in active galactic nuclei (AGN) is fundamental to the evolution of galaxies. AGN themselves are largely explained in the...
