Séminaire – Junais (Instituto de Astrofísica de Canarias)
"Low surface brightness galaxies in the era of deep large-sky surveys and artificial intelligence" Low surface-brightness (LSB) galaxies, which are typically fainter than the night sky, contribute to the majority of the total number density of galaxies in the universe. Therefore, they are a...

Soutenance de thèse – Mei PALANQUE – 10h00
"New radiative transfer methods in numerical simulation of the epoch of reionisation" In current cosmological simulations, the radiative transfer modules generally rely on the M1 approximation, which has some glaring flaws related to its fluid-like behaviour, such as spurious pseudo-sources and...

Séminaire – Tristan Hoellinger (IAP) – 13h00
"Implicit Likelihood Cosmological Inference: Simulations & Diagnostics" Ongoing cosmological surveys map the large-scale structure of the Universe across immense volumes. Extracting robust cosmological information from these data requires fast, high-precision simulations of the survey...

Séminaire – Luc Blanchet (IAP)
"Dark matter and the MOND phenomenology in galaxies." We discuss the phenomenology of dark matter at galactic scales and the intriguing MOND (Modified Newtonian Dynamics) formula for the rotation curves of galaxies, the baryonic Tully-Fisher relation (BTFR) and the radial acceleration relation...

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...
