Dark Energy and Neutrino Mass – the Latest Hints from DESI Using Baryon Acoustic Oscillations
The DESI collaboration (Dark Energy Spectroscopic Instrument) confirmed its groundbreaking results on dynamical dark energy through the largest 3-dimensional Universe map it observed. This talk highlights how DESI’s Baryon Acoustic Oscillation (BAO) measurements from Data Release 2 further challenge the ΛCDM paradigm, the standard cosmology for the past 30 years. The second part of this talk ...

4MOST-Cosmology Redshift Survey: Overview
In this talk, I will present the 4-metre Multi-Object Spectroscopic telescope as well as the recent news related to the on-going Science Phase Verification which aims to make different tests for all 4MOST science cases. I will in a second time present in more details the Cosmology Redshift Survey, especially the Bright Galaxies and Luminous Red Galaxies samples, as well as the quality checks an...

Simulating Accretion and Early Light Curve in Tidal Disruption Event (TDE)
The tidal disruption of a star by a supermassive black hole and consequent accretion can lead to a transient electromagnetic flare in multiple bands. However, the origin of the detected emission from such tidal disruption events (TDEs) remains an open question. In this talk, I will discuss the potential emission mechanisms in TDEs during accretion disk formation, implied by series of 3D radiati...
