CharlaGRB 101225A: a stellar murder on Christmas Day
Long Gamma-Ray Bursts (GRBs) are the most dramatic examples of massive stellar deaths, usually associated with supernovae ( Woosley et al. 2006). They release...

CharlaGrowing black holes: from the first seeds to active galactic nuclei
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...

CharlaGTC spectroscopic study of stellar clusters in M81
The nearby spiral galaxy M81 contains a population of 3 kinds of stellar clusters - super star clusters, globular clusters and fuzzy clusters. Over the past few...

CharlaHerMES HFLS3: A dust-obscured massive maximum-starburst galaxy at a redshift of 6.34
How do the first galaxies form and evolve? Optical and near-infrared deep surveys are now finding galaxies at very high redshifts. However, they are typically...
