HI-bearing dark galaxies predictions from constrained Local Group simulations: how many and where to find them
Guacimara GarcÃa-Bethencourt, Arianna Di Cintio, Sébastien Comerón +7
Dark galaxies are small, DM-dominated halos whose gas remains in hydrostatic and thermal equilibrium and has never formed stars. They are of particular interest because they repres…
Why the Northern Hemisphere Needs a 30-40 m Telescope and the Science at Stake: Mapping formation pathways of nuclear star clusters across galaxies
Francesca Pinna, Isabel Pérez, Anna Ferré-Mateu +21
Nuclear star clusters (NSCs) are dense, compact stellar systems only a few parsecs across, located at galaxy centers. Their small sizes make them difficult to resolve spatially. NS…
NASIM: Revealing the low surface brightness Universe from legacy VISTA data
Elham Saremi, Ignacio Trujillo, Mohammad Akhlaghi +5
Near-infrared imaging is a powerful technique in observational astronomy, but the bright background, primarily from the EarthÅ atmosphere, makes the detection of faint features pa…
Relatively young thick disks in star-forming late-type galaxies
Natascha Sattler, Francesca Pinna, Sebastien Comerón +4
We trace the evolution of eight edge-on star-forming disk galaxies by analyzing stellar population properties of their thin and thick disks. These galaxies have relatively low stel…
Spatially resolved circumnuclear coronal emission in nearby Seyfert galaxies
S. Comerón, A. Prieto, P. Dabhade
Coronal lines are forbidden emission lines with a ionisation potential . They are linked to energetic phenomena triggered by AGNs in the circumnuclear mediu…
Assessing the accuracy of the star formation rate measurements by direct star count in molecular clouds
Sami Dib, Jian Wen Zhou, Sébastien Comerón +8
Star formation estimates based on the counting of YSOs is commonly applied to nearby star-forming regions in the Galaxy. With this method, the SFRs are measured using the counts of…
