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…
On the Nature of the C IV-bearing Circumgalactic Medium at z~1
Suyash Kumar, Hsiao-Wen Chen, Zhijie Qu +5
This paper presents a detailed study of the physical properties of seven C IV absorbers identified at z_abs = 0.68-1.28 along the line of sight toward QSO PG 1522+101 (z_QSO = 1.33…
