Studying the resolved stellar populations of the different structural components that build massive galaxies directly unveils their assembly history. We aim at...

PublicationA Tale of Two Disks: Mapping the Milky Way with the Final Data Release of APOGEE
We present new maps of the Milky Way disk showing the distribution of metallicity ([Fe/H]), α-element abundances ([Mg/Fe]), and stellar age, using a sample of...

PublicationDwarf Galaxies with Central Cores in Modified Newtonian Dynamics Gravity
Some dwarf galaxies are within the Mondian regime at all radii, i.e., the gravitational acceleration provided by the observed baryons is always below the...

PublicationEvolution of the Size–Mass Relation of Star-forming Galaxies Since z = 5.5 Revealed by CEERS
We combine deep imaging data from the CEERS early release JWST survey and Hubble Space Telescope imaging from CANDELS to examine the size–mass relation of star...

PublicationExploring the Galactic Warp through Asymmetries in the Kinematics of the Galactic Disk
Previous analyses of large databases of Milky Way stars have revealed the stellar disk of our Galaxy to be warped and that this imparts a strong signature on...

PublicationFirst Look at z > 1 Bars in the Rest-frame Near-infrared with JWST Early CEERS Imaging
Stellar bars are key drivers of secular evolution in galaxies and can be effectively studied using rest-frame near-infrared (NIR) images, which trace the...

PublicationFlares, Warps, Truncations, and Satellite: The Ultra-thin Galaxy UGC 11859
The structure of the outskirts of galaxies provides valuable information about their past and evolution. Due to their projected orientation, edge-on isolated...

PublicationGalaxies Going Bananas: Inferring the 3D Geometry of High-redshift Galaxies with JWST-CEERS
The 3D geometries of high-redshift galaxies remain poorly understood. We build a differentiable Bayesian model and use Hamiltonian Monte Carlo to efficiently...

PublicationObserving the Stellar Halo of Andromeda in Cosmological Simulations: The AURIGA2PANDAS Pipeline
We present a direct comparison of the Pan-Andromeda Archaeological Survey (PAndAS) observations of the stellar halo of M31 with the stellar halos of six...
