The evolution of the content of heavy elements in galaxies, the relative chemical
abundances, their spatial distribution, and how these scale with various galactic properties …

Numerical simulations predict that metal-poor gas accretion from the cosmic web fuels the
formation of disk galaxies. This paper discusses how cosmic gas accretion controls star …

Diffuse ionized gas (DIG) is prevalent in star-forming galaxies. Using a sample of 365 nearly
face-on star-forming galaxies observed by Mapping Nearby Galaxies at APO, we …

The last seven years have seen an explosion in the number of Integral Field galaxy surveys,
obtaining resolved 2D spectroscopy, especially at high-redshift. These have taken …

We have initiated a new survey for local extremely metal-poor galaxies (EMPGs) with
Subaru/Hyper Suprime-Cam (HSC) large-area (∼ 500 deg 2) optical images reaching a 5σ …

Context. The study of large and representative samples of low-metallicity star-forming
galaxies at different cosmic epochs is of great interest to the detailed understanding of the …

Using integral field spectroscopic data of 24 nearby spiral galaxies obtained with the Multi
Unit Spectroscopic Explorer, we derive empirical calibrations to determine the metallicity of …

Context. Tracing the molecular gas-phase in low-mass star-forming galaxies becomes
extremely challenging due to significant UV photo-dissociation of CO molecules in their low …

Gas inflow feeds galaxies with low-metallicity gas from the cosmic web, sustaining star
formation across the Hubble time. We make a connection between these inflows and …

Models of galaxy formation predict that gas accretion from the cosmic web is a primary driver
of star formation over cosmic history. Except in very dense environments where galaxy …
