"Galaxy metallicity measurements at high redshift: probing galaxy growth over the past 12 billion years" Abstract: The scaling of galaxy gas-phase metallicity with stellar mass and star-formation rate is a sensitive probe of the cycle of baryons and...

3D mapping of the dusty, magnetized ISM with starlight polarization The coming decade will mark a milestone in our understanding of interstellar magnetism: achieving a first reconstruction of the Galactic magnetic field in 3D. This will be crucial for...

"The Formation of Ultra-Diffuse Galaxies from Passive Evolution in the RomulusC Galaxy Cluster Simulation" Current cosmological simulations have so far been limited to studying the formation of ultra diffuse galaxies (UDGs) in isolation, or with...

"Learning Cosmology with the First Stars" I will describe how upcoming 21-cm measurements during cosmic dawn will provide a trove of new cosmological information. This era saw the formation of the first stars, which excited neutral hydrogen and allowed it...

Are long-term N-body simulations reliable? Abstract: Astrophysicists rely on solution for the N-body problem for a myriad of dynamics problems, from those in dark matter dynamics to those in planetary dynamics. Over 50 years ago, Miller found that errors...

LYRA: Galaxy formation with a multi-phase ISM, individual stars and resolved supernovae in a cosmological context Abstract: I will present the LYRA project: A high resolution galaxy formation model built within the cosmological hydro-dynamical framework...

“Dynamical Chaos near Corotation: Limits on cold radial migration” Abstract: After an initial epoch of assembly, spiral galaxies like the Milky Way evolve primarily under the influence of slow, internal processes. This secular evolution rearranges the...

"Sweating the small stuff: Or how I learned to START worrying and love the smallest galaxies" Abstract: The currently favored cosmological paradigm, Lambda Cold Dark Matter Theory (LCDM), has been widely successful in predicting the counts, clustering...
