Bars drive gas inflow. As the gas flows inward, shocks and shear occur along the bar dust lanes. Such shocks and shear can affect the star formation (SF) and change the gas properties. For four barred galaxies, we present H α velocity gradient maps

We explore the chemodynamical properties of the Galaxy in the azimuthal velocity V _ϕ and metallicity [Fe/H] space using red giant stars from Gaia Data Release 3. The row-normalized V _ϕ –[Fe/H] maps form a coherent sequence from the bulge to the

We study bulge formation in MW/M31-like galaxies in a $\Lambda$-cold dark matter scenario, focusing on the origin of high- and low-Sersic index bulges. For this purpose we use TNG50, a simulation of the IllustrisTNG project that combines a resolution

Feedback from active galactic nuclei (AGN) has become established as a fundamental process in the evolution of the most massive galaxies. Its impact on Milky Way (MW)-mass systems, however, remains comparatively unexplored. In this work, we use the A

Galactic bars can drive cold gas inflows towards the centres of galaxies. The gas transport happens primarily through the so-called bar ``dust lanes'', which connect the galactic disc at kpc scales to the nuclear rings at hundreds of pc scales much l

We employ our Bayesian Machine Learning framework BINGO (Bayesian INference for Galactic archaeOlogy) to obtain high-quality stellar age estimates for 68,360 red giant and red clump stars present in the 17th data release of the Sloan Digital Sky Surv

We identify and characterise a Milky Way-like realisation from the Auriga simulations with two consecutive massive mergers $\sim2\,$Gyr apart at high redshift, comparable to the reported Kraken and Gaia-Sausage-Enceladus. The Kraken-like merger ($z=1

Understanding galaxy evolution requires investigating which physical processes dominate in different cosmic epochs. In the early Universe, these are primarily caused by interactions and violent processes, but, since at least z ~ 1-2, bar-driven secul

In this talk I will report the results on bulge formation in MW- and M31 like-galaxies obtained from state-of-the-art high-resolution cosmological magneto-hydrodynamical simulations: the Auriga suite and TNG50. We characterise photometric bulges by a
