We used the GMOS integral field unit on the Gemini South telescope to investigate the kinematics of the circum-nuclear ionized gas in two active galaxies: NGC...

Over the past years observations of young and populous star clusters have shown that the stellar initial mass function (IMF) can be conveniently described by a...

Tests of the concordance cold dark matter model on the scale of galaxies are so far inconclusive due to our poor understanding of the interplay between baryons...

In the last decade we have explored the cosmic depths and found a statistically significant number of galaxies well into the Epoch of Reionization. However, our...

The plan of the Iranian National Observatory (INO) is to build within the next 5 years an active 3 meter telescope with a possible adaptive secondary on a...

The Extreme Universe Space Observatory (EUSO) Space Program on the International Space Station (ISS) is the first space-based mission worldwide in the field of...

The Sloan Digital Sky Survey is currently the largest spectroscopic survey of extragalactic objects and one of the most ambitious observational programs ever...

All the elements from carbon to uranium present in the Solar System were produced by hundreds to thousands of stars belonging to different stellar generations...

The life cycle of baryonic matter in a galaxy is driven by the exchange of material between the interstellar medium (ISM) and stars, which are the agents of...
