A radio continuum view of Stephan's Quintet: age, dynamics and origin of the shock
K. Rajpurohit, E. O'Sullivan, G. Schellenberger +10
We present a detailed, multi-band radio continuum study of the compact galaxy group Stephan's Quintet (HCG 92). We use a combination of new (MeerKAT, uGMRT) and archival (LOFAR, VL…
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…
Shock-Enhanced C+ Emission and the Detection of H2O from Stephan's Quintet's Group-Wide Shock using Herschel
P. N. Appleton, P. Guillard, F. Boulanger +20
We present the first Herschel spectroscopic detections of the [OI]63 and [CII]158 micron fine-structure transitions, and a single para-H2O line from the 35 x 15 kpc^2 shocked inter…
