Soutenance de thèse – Lucie Correia

"Analyzing the millimeter to centimeter emission of nearby galaxies" Compared to the well-studied infrared and radio domains, galaxy emission in the millimeter–centimeter range (300–30 GHz) has been far less explored. This domain is challenging to study due to faint signals, overlapping...

Séminaire – Bernardo Cervantes Sodi (UNAM)

"Faint but not forgotten: what simulations reveal about Low Surface Brightness Galaxies" Low Surface Brightness Galaxies (LSBGs) constitute a substantial fraction of galaxies in the local Universe, being primarily bulge-less, late-type galaxies, bluer and more gas-rich than their high surface...

Soutenance de thèse – Srikanth Nagesh

"Dynamics of galaxies as probes to constrain gravity models" In this thesis, we test cosmological and gravitational models (ΛCDM and MOND) using idealized galaxy simulations. Ultra-diffuse galaxies (UDGs) in the Coma cluster exhibit higher velocity dispersions than MOND predicts. Our MOND...

Séminaire – Prachi Prajapati (University of Cologne)

"Vz-GAL: Probing Cold Molecular Gas in Dusty Star-forming Galaxies at z=1-6." Reconstructing the physical mechanisms that have shaped present-day galaxies remains a primary goal in observational cosmology. I will introduce the Vz-GAL VLA CO(1–0) Survey, a comprehensive endeavor targeting...

Séminaire – Michal Bilek (Astronomical Observatory Belgrade)

"Formation of Fornax dwarf spheroidal and the survival of its globular clusters " The presence of globular clusters (GCs) in the Fornax dwarf spheroidal is an important test of the theories aiming to address the missing mass problem. The problem is that in most of them, the GCs are expected to...

Séminaire – Jean-Baptiste Jolly (MPE)

"NOEMA3D: Inflowing Gas at Subgalactic Scales in Massive Star Forming Galaxies at z~1-2" How is gas transported within galaxies at cosmic noon? What is the role of bars and spiral arms in the build-up of galactic structures? To try to answer these questions I will present NOEMA3D, an ongoing...

Séminaire – Elena Asencio (University of Bonn)

"Do the stellar streams of the Milky Way point to a past Milky Way-Andromeda interaction?"Stellar streams around the Milky Way (MW) can provide valuable insights into its history and substructure formation. Previous studies suggested that several MW streams could have a correlated origin with the...
