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…
