Formation of extragalactic Star Clusters
Gerhard Hensler, Yannick Hein, Alessandro Boselli +1
The outskirts of galaxies show their beauty by an assembly of Globular Clusters and satellite galaxies, but also by interactions with their environment. Galaxies in clusters experi…
A Virgo Environmental Survey Tracing Ionised Gas Emission (VESTIGE) XX. Star formation in the tidal tail of NGC 4254
A. Boselli, A. Lupi, P. Serra +26
ALMA 12CO(1-0) observations of 42 star-forming regions located outside the disc of the Virgo Cluster galaxy NGC4254 within an HI gas tail produced during the galaxy's interaction w…
A Virgo Environmental Survey Tracing Ionised Gas Emission (VESTIGE). XXI. Statistical properties of individual HII regions in perturbed galaxies
A. Boselli, M. Fossati, Y. Roehlly +8
We use narrow-band Halpha+[NII] imaging data gathered during VESTIGE, a blind survey of the Virgo cluster carried out with MegaCam at the CFHT, to identify HII regions in 385 galax…
Self-regulated galaxy evolution within a self-consistently varying galaxy-wide IMF
Lukas Hof, Pavel Kroupa, Gerhard Hensler +1
Semi-analytical evolution models of galaxies are a useful and computationally inexpensive tool for fast assessment of individual properties and their evolution. In this work, speci…
Glance: A Comprehensive Framework for Galactic Archaeology
Iris Breda, Glenn van de Ven, Sabine Thater +8
A central topic in extragalactic astronomy is understanding the formation and evolutionary histories of galaxies. These systems often comprise multiple structural components with d…
