Over the past decade, increasingly robust estimates of the dense molecular gas content in
galaxy populations between redshift z= 0 and the peak of cosmic galaxy/star formation (z∼ …

We develop a hybrid model of galactic chemical evolution that combines a multiring
computation of chemical enrichment with a prescription for stellar migration and the vertical …

Context. The second Gaia data release (Gaia DR2) contains high-precision positions,
parallaxes, and proper motions for 1.3 billion sources as well as line-of-sight velocities for …

Several lines of evidence suggest that the Milky Way underwent a major merger at z∼ 2 with
the Gaia-Sausage-Enceladus (GSE) galaxy. Here we use H3 Survey data to argue that GSE …

As they grow, galaxies can transition from irregular/spheroidal with 'bursty'star formation
histories (SFHs), to discy with smooth SFHs. But even in simulations, the direct physical …

We present the KMOS 3D survey, a new integral field survey of over 600 galaxies at 0.7< z<
2.7 using KMOS at the Very Large Telescope. The KMOS 3D survey utilizes synergies with …

We use cosmological simulations to study a characteristic evolution pattern of high-redshift
galaxies. Early, stream-fed, highly perturbed, gas-rich discs undergo phases of dissipative …

We introduce a new model for the structure and evolution of the gas in galactic discs. In the
model the gas is in vertical pressure and energy balance. Star formation feedback injects …

We analyze a sample of solar neighborhood stars that have high-quality abundance
determinations and show that there are two distinct regimes of [α/Fe] versus age, which we …

We study the origin of high-redshift, compact, quenched spheroids (red nuggets) through the
dissipative shrinkage of gaseous discs into compact star-forming systems (blue nuggets) …
