Using high-resolution spectra of 8 Active Galactic Nuclei (AGN) observed with INT we found that shapes of narrow emission lines indicate very complex structure...
The study of asteroids that present sporadic cometary activity, is of fundamental importance to address several astronomical problems like the end states of...
Sporadic cometary-like activity has been observed in three asteroids of the main belt (the Main Belt Comets, MBCs, Hsieh and Jewitt 2006, Science, 312, 561):...
The Nature of Dwarf Elliptical Galaxies: An Observing Project for OSIRIS
Although dwarf elliptical galaxies are the dominant galaxy population in nearby clusters, their origin and nature remain a mystery. The main aim of this project...
The Nature of Galactic Bulges from SAURON Absorption Line Strength Maps
We discuss SAURON absorption line strength maps of a sample of 24 early-type spirals, mostly Sa. From the Lick indices H$eta$, Mg b and Fe 5015 we derive SSP...
