Unveiling galaxy chemical enrichment mechanisms out to z~8 from direct determination of O & Ar abundances from JWST/NIRSPEC spectroscopy

Souradeep Bhattacharya, Magda Arnaboldi, Ortwin Gerhard +2

Galaxy chemical enrichment mechanisms have primarily been constrained by [α/Fe] and [Fe/H] measurements of individual stars and integrated light from stellar populations. However…

Testing kinematic distances under a realistic Galactic potential

Glen H. Hunter, Mattia C. Sormani, Jan P. Beckmann +15

Obtaining reliable distance estimates to gas clouds within the Milky Way is challenging in the absence of certain tracers. The kinematic distance approach has been used as an alter…
