Tidal features in the outskirts of galaxies yield unique information about their past interactions and are a key prediction hierarchical structure formation paradigm. The Vera C. Rubin Observatory is poised to deliver deep observations for potentially millions objects with visible tidal features, but inference galaxy interaction histories from such not straightforward. Utilising automated techniques human visual classification conjunction realistic mock images produced using NEWHORIZON...
We present an overview of the Middle Ages Galaxy Properties with Integral Field Spectroscopy (MAGPI) survey, a Large Program on ESO/VLT. MAGPI is designed to study physical drivers galaxy transformation at lookback time 3-4 Gyr, during which dynamical, morphological, and chemical properties galaxies are predicted evolve significantly. The survey uses new medium-deep adaptive optics aided MUSE observations fields selected from GAMA providing wealth publicly available ancillary...
ABSTRACT Tidal features provide signatures of recent mergers and offer a unique insight into the assembly history galaxies. The Vera C. Rubin Observatory’s Legacy Survey Space Time (LSST) will enable an unprecedentedly large survey tidal around millions To decipher contributions to galaxy evolution it be necessary compare observed with theoretical predictions. Therefore, we use cosmological hydrodynamical simulations NewHorizon, eagle, IllustrisTNG, Magneticum produce LSST-like mock images z...
ABSTRACT We use comparisons between the Sydney-AAO Multi-object Integral Field Spectrograph (SAMI) Galaxy Survey and equilibrium galaxy models to infer importance of disc fading in transition spirals into lenticular (S0) galaxies. The local S0 population has both higher photometric concentration lower stellar spin than spiral galaxies comparable mass we test whether this separation can be accounted for by passive aging alone. construct a suite dynamically self-consistent models, with bulge,...
ABSTRACT We use the ‘Middle Ages Galaxy Properties with Integral field spectroscopy’ (MAGPI) survey to investigate whether galaxies have evolved in distribution of their stellar angular momentum past 3–4 Gyr, as probed by observational proxy for spin, λR. 2D kinematics measure λR along detailed photometric models estimate galaxy ellipticity. The combination these measurements quantifies kinematic classes ‘fast rotators’ and rarer ‘slow rotators’, which show no regular rotation line-of-sight...

We use the `Middle Ages Galaxy Properties with Integral field spectroscopy' (MAGPI) survey to investigate whether galaxies have evolved in distribution of their stellar angular momentum past 3-4 Gyr, as probed by observational proxy for spin, $\lambda_{R}$. 2D kinematics measure $\lambda_{R}$ along detailed photometric models estimate galaxy ellipticity. The combination these measurements quantifies kinematic classes `fast rotators' and rarer `slow rotators', which show no regular rotation...
