Coronal heating, chromospheric heating, and the heating & acceleration of the solar wind, are well-known problems in solar physics. Additionally, knowledge of...

Despite stellar magnetic activity being present in most cool stars, its effects on spectroscopic observations are still not well understood. Several activity...

The origin and formation of the Milky Way bulge remains poorly understood, in part because high quality observations of the bulge have generally been restricted...

We observed EX Draconis in BV I colours for 40 nights, covering 3 outburst events, with the aim to study the disc evolution. Here, we present a preliminary...

We present a detailed spectrophotometric analysis of the blue compact dwarf galaxy Mrk5 (NGC353, Haro3), based on deep BVRIJHK broad-band and H α narrow-band...

We present optical integral field spectroscopy analysis of the main components, with the exception of the halo, as well as of the detected small-scale...

Blue Compact Dwarf (BCD) galaxies are metal-poor and gas-rich systems undergoing intense, spatially extended star-forming activity. These galaxies offer a...

We have constructed an instrument able to map the sky at 10 GHz using circular scans with an angular resolution of 1deg. This instrument consist of a spinning...
