Measuring the ISM Content of Nearby, Luminous, Type 1 and Type 2 QSOs through CO and [C II]
Yuanze Luo, A. O. Petric, R. M. J. Janssen +18
We present observations of CO(1--0) and CO(2--1) lines from the Institut de radioastronomie millimétrique (IRAM) 30m telescope toward 20 nearby, optically luminous type 2 quasars (…
Joint Optical and Infrared Observations of N and O Reveal the Dust-Obscured Gas in Haro 3
Yuguang Chen, Tucker Jones, Ryan L. Sanders +22
Accurate chemical compositions of star-forming regions are a critical diagnostic tool to characterize the star formation history and gas flows which regulate galaxy formation. Howe…
Reply to: Effects of density and temperature variations on the metallicity of Mrk 71
Yuguang Chen, Tucker Jones, Ryan Sanders +9
In Chen et al., 2023 (C23; arXiv:2304.09898), we introduced a new method to directly measure temperature fluctuations and applied it to a nearby dwarf galaxy, Mrk 71, finding a tem…
Shock enhanced [CII] emission from the infalling galaxy Arp 25
Dario Fadda, Jessica S. Sutter, Robert Minchin +1
We present SOFIA observations with HAWC+ and FIFI-LS of the peculiar galaxy Arp 25, also known as NGC 2276 or UGC 3740, whose morphology is deformed by its impact with the intra-gr…
Characterization and Absolute Calibration of the Far Infrared Field Integral Line Spectrometer for SOFIA
Dario Fadda, Sebastian Colditz, Christian Fischer +7
We present the characterization and definitive flux calibration of the Far-Infrared Field Integral Line Spectrometer (FIFI-LS) instrument on-board SOFIA. The work is based on measu…
