Stars originate by the gravitational collapse of a turbulent molecular cloud of a diffuse medium, and are often observed to form clusters. Stellar clusters...

Teleportation of physical objects, transferring from one place to another without passing through intermediate locations, is not possible. However...

The evidence for the existence of dark energy is conclusive, but its nature remains one of the most puzzling mysteries in all of physics. Astronomical surveys...

In the local universe, galaxies fall into one of two populations: a star-forming blue cloud and a red sequence lacking star formation. At redshift z ~ 1.5...

For the beginning of my presentation, I would like to briefly present the astronomy program at the Faculty of Mathematics, Physics and Informatics of Comenius...

The disc of galaxies is made of the superposition of a thin and a thick disc. Thick discs are seen in edge-on galaxies as excesses of light a few thin disc...

Milky Way and most spiral galaxies present some features in the outer part of its disk such as S-warping or U-warping, flaring, lopsidedness, truncation/non...

Modern imaging surveys provide a fundamental tool in order to study the morphologicalproperties of galaxy populations in the nearby and the distant Universe. In...

It has been thirty years since the seminal work of Alan Dressler on the density-morphology relation, which established environment as a driving mechanism for...
