Optical Strong Line Ratios Cannot Distinguish Between Stellar Populations and Accreting Black Holes at High Ionization Parameters and Low Metallicities

Nikko J. Cleri, Grace M. Olivier, Bren E. Backhaus +24

High-redshift observations from JWST indicate that optical strong line ratios do not carry the same constraining power as they do at low redshifts. Critically, this prevents a sepa…

A giant galaxy in the young Universe with a massive ring

Tiantian Yuan, Ahmed Elagali, Ivo Labbe +12

In the local (redshift z~0) Universe, collisional ring galaxies make up only ~0.01% of galaxies and are formed by head-on galactic collisions that trigger radially propagating dens…
