  Connecting Present-day Galaxies and their Progenitors with Stellar Population-Dynamics

  This talk will present my PhD project, which investigates the evolution of galaxy orbital components (cold, warm, hot, and counter-rotating orbits) fromz~1 to z~0 . By combining high signal-to-noise LEGA-C spectra of approximately 3,000 galaxies with Schwarzschild orbit-superposition models and simulations, the project aims to reconstruct galaxy assembly histories, uncovering the intrinsic properties and formation pathways of these orbital structures.

  Title: "A dynamical mass-map of the Fornax galaxy cluster"

  Abstract - The Fornax cluster provides an unparalleled opportunity to investigate the formation and evolution of early-type galaxies in a dense environment. Thanks to its proximity and building on a wealth of ancillary data, the Fornax cluster provides a unique chance to study the growth of galaxies and intracluster light in a dense environment in great detail. Using the spectroscopic observations from the Visible Multi-Object Spectrograph at Very Large Telescope (VLT/VIMOS) and mock HI observations of Fornax from TNG50 simulations allow us to learn about mass-assembly and intra-cluster environment. In this talk, I will present the kinematics of the GCs of the Fornax cluster core region and will discuss the distribution of baryonic and dark matter around NGC1399. I will discuss the kinematic substructure of the intra-cluster GCs, which indicates their accreted nature. In addition, I will also show that Fornax-like halos in TNG50 simulations hold a large amount of cold gas in their IC environment.
