SOFIA observations of far-IR fine-structure lines in galaxies to measure metallicity

Luigi Spinoglio, Juan Antonio Fernandez-Ontiveros, Matthew A. Malkan +8

We present new and archival SOFIA FIFI-LS far-IR spectroscopic observations of 25 local galaxies of either the [OIII]52um and/or the [NIII]57um lines. Including other 31 galaxies f…

MUSEQuBES: Physical conditions, origins, and multi-element abundances of the circumgalactic medium of an isolated, star-forming dwarf galaxy at z=0.57

Sean D. Johnson, Nishant Mishra, Sowgat Muzahid +13

In dwarf galaxy models, outflows expel metal-enriched interstellar medium (ISM) into the circumgalactic medium (CGM) to reproduce their observed low metallicities, but measurements…

Non-equilibrium ionization in the multiphase circumgalactic medium -- impact on quasar absorption-line analyses

Suyash Kumar, Hsiao-Wen Chen

This paper presents an updated framework for studying the ionizing conditions and elemental abundances of photoionized, metal-enriched quasar absorption systems. The standard assum…
