SNe and their impact during the early evolution of Type I Globular Clusters
Santiago Jiménez, Guillermo Tenorio-Tagle, Sergiy Silich
The iron composition of globular clusters (GCs) is homogeneous in all but a few massive clusters, despite the presence of multiple stellar populations. Hence, most if not all the s…

On the early evolution of massive star clusters: the case of cloud D1 and its embedded cluster in NGC 5253
Sergiy Silich, Guillermo Tenorio-Tagle, Sergio Martinez-Gonzalez +1
We discuss a theoretical model for the early evolution of massive star clusters and confront it with the ALMA, radio and infrared observations of the young stellar cluster highly o…
Supersonic turbulence in Giant HII Regions: clues from 30 Doradus
Jorge Melnick, Guillermo Tenorio-Tagle, Eduardo Telles
The tight correlation between turbulence and luminosity in Giant HII Regions is not well understood. While the luminosity is due to the UV radiation from the massive stars in the i…
Supernovae within Pre-existing Wind-Blown Bubbles: Dust Injection vs. Ambient Dust Destruction
Sergio Martínez-González, Richard Wünsch, Sergiy Silich +3
By means of 3-D hydrodynamical simulations, here we evaluate the impact that supernova explosions occurring within wind-driven bubbles have on the survival or destruction of dust g…
The full evolution of supernova remnants in low and high density ambient media
Santiago Jimenez, Guillermo Tenorio-Tagle, Sergiy Silich
Supernova explosions and their remnants (SNRs) drive important feedback mechanisms that impact considerably the galaxies that host them. Then, the knowledge of the SNRs evolution i…
