A MeerKAT view of the Neutral Atomic Gas in Stephan's Quintet
K. Rajpurohit, E. O'Sullivan, G. Schellenberger +7
We present new MeerKAT 21cm spectral line observations of the neutral hydrogen gas in the compact galaxy group Stephan's Quintet (HCG 92). These data provide a significantly improv…
SQ-A: A Collision Triggered Starburst in Intra-Group Medium of Stephan's Quintet
C. K. Xu, C. Cheng, M. S. Yun +12
We present new observational evidence supporting the hypothesis that SQ-A, a starburst in the intra-group medium (IGrM) of Stephan's Quintet (SQ), is triggered by a high-speed coll…
HCG 57: Evidence for shock-heated intergalactic gas from X-rays and optical emission line spectroscopy
Ewan O'Sullivan, P. N. Appleton, B. A. Joshi +5
We present Chandra and XMM-Newton X-ray observations of the compact group HCG 57, and optical integral field spectroscopy of the interacting galaxy pair HCG 57A/D. These two spiral…
Bird's-eye View of Molecular Gas across Stephan's Quintet Galaxy Group and Intra-group Medium
B. H. C. Emonts, P. N. Appleton, U. Lisenfeld +15
We present the large-scale distribution and kinematics of cold molecular gas across the compact galaxy group Stephan's Quintet, based on CO(2-1) observations performed with the Ata…
