The role of the tropopause layer altitude on the infrared quality of astronomical sites
The infrared sky quality is an important parameter to take into account for the evaluation of astronomical sites. The traditional idea of considering higher...
The Role of Tidal Interactions in Driving Galaxy Evolution
We carry out a statistical analysis of galaxy pairs selected from chemical hydrodynamical simulations with the aim at assessing the capability of hierarchical...
How the stellar mass of early-type galaxies is assembled remains an open question. Are the stars formed in situ, possibly triggered by merger events, or do they...
