One of the most widely researched topics in Extragalactic Astrophysics in the last decades is how early-type galaxies have formed their stars and assembled. In...

With imaging at 3.6 and 4.5 microns where the light in nearby galaxies is dominated by old stars, the Spitzer Survey of Nearby Galaxies (S4G) stands poised for...

We present a detailed study of the lenticular galaxy NGC 1023 kinematics. To perform this analysis we use planetary nebulae (PNe). which can be observed in the...

Red supergiant stars (RSGs) are among brightest stars in the Universe. Their extreme luminosities and young ages make them excellent candidates to probe young...

Common wisdom identifies hydrogen lines in photoionized region with recombination lines. However, these lines can also be excited by different atomic mechanisms...

The epoch of reionization has been predicted to leave an imprint on the star formation histories of dwarf galaxies. I will briefly review theoretical ideas and...
