Tiny Galaxies, Mighty Nitrogen: Linking Chemical Anomalies to Compact Galaxies at High Redshift using JWST/JADES

Urvi Thakurdesai, Xihan Ji, Yuki Isobe +18

The origin of anomalous chemical enrichment in high-redshift galaxies discovered by JWST remains a key question in galaxy evolution. Enhanced nitrogen abundances have been identifi…

Introducing $Δ V_{⋆- g}$ : a new universal kinematic disturbance parameter

Jonah M. Powley, Rebecca J. Smethurst, Chris J. Lintott +1

We introduce a new kinematic disturbance parameter, $Δ V_{⋆- g}$ (pronounced `DVSG'), which takes advantage of integral field spectroscopy (IFS) to quantify differences between a…
