Spectral energy distributions (SEDs) of the central few tens of parsec region of some of the nearest active galactic nuclei (AGN) are presented. Peering into...

Early-type dwarfs (dEs) are by far the most abundant galaxy population in nearby clusters. Whether these objects are primordial, or recent end-products of the...

In the Λ-CDM galaxy formation paradigm, the star formation history of a galaxy is coupled to the total mass of its dark matter halo through processes like...

Gravitational lensing is a powerful astrophysical tool which allow us to studythe dark sector of the universe. Some of these applications include from thestudy...

Gamma Ray Bursts (GRBs) are among the most energetic transient phenomena frequently followed up by different observatories and yet several fundamental questions...

We propose ground-based monitoring system for atmospheric water vapor based on wide-range spectra at 20 – 30 GHz and 50 – 60 GHz ranges. It observes in these...

The window of very high energy (VHE) gamma-ray astronomy was only opened 20 years ago by the first observation of TeV gamma-rays from the CRAB nebula. Since...

One of the most puzzling questions in the field of galaxy evolution is how agalaxy manages to grow a supermassive black hole of 10^6-10^9 solar masses atits...
