Shining a Light on the Connections between Galactic Outflows Seen in Absorption and Emission Lines

The Astrophysical Journal
Galactic outflows provide important feedback effects to regulate the evolution of host galaxies. Two primary diagnostics of outflows are broad and/or blueshifted emission and absorption lines.

Spectrophotometry of three emission-line galaxies.

The Astrophysical Journal, 1973
Spectrophotometric data concerning three blue emission-line galaxies were obtained from image-tube spectrograms secured with the 84-inch reflector of the Kitt Peak National Observatory. Analysis of these data indicated a level of excitation similar to that of low- or moderate-excitation galactic H II regions.

Predicting CO and dust emission of star-forming galaxies

Astronomy & Astrophysics
In this work, we investigate whether dwarf galaxies differ from spirals and whether star formation produces radio and far-infrared (FIR) emission in the same way as it does for spiral galaxies.

Extremely Metal-poor Galaxies in DESI DR1: Connections to Galaxies in the Early Universe

The Astronomical Journal
Extremely metal-poor galaxies (XMPGs), defined as having metallicities below 10% of the solar value, are considered possible local analogs to primordial systems and offer a unique window into early galaxy evolution.
