Galaxy cluster formation from the large-scale structure: a case study of the Abell 2125 complex at z=0.247
C153 SW cD
2014/12/24
The structure of the universe is believed to have formed by clustering hierarchically from small to large scales. Much of this evolution occurs very slowly but at a few special times more rapid, viole...
A Deep Radio Survey of Abell 2125. II. Accelerated Galaxy Evolution during a Cluster-Cluster Merger
Abell galaxies
2014/12/24
Using our extensive radio, optical, near-IR, and X-ray imaging and spectroscopy, we consider the reason for the unusually large number of radio-detected galaxies, mostly found outside the cluster core...
A Deep Radio Survey of Abell 2125. III. The Cluster Core: Merging and Stripping
evolution starburst
2014/12/24
We use radio, near-IR, optical, and X-ray observations to examine dynamic processes in the central region of the rich galaxy cluster Abell 2125. In addition to the central triple of E and cD galaxies,...
Elliptical Weighted HOLICs for Weak Lensing Shear Measurement part2:PSF correction and application to Abell 370
Elliptical Weighted HOLICs for Weak Lensing Shear Measurement part2:PSF correction and application to Abell 370
2011/10/20
We have developed a new method(E-HOLICs) of estimating gravitational shear by adopting an elliptical weight function to measure background galaxy images in our previous paper. Following to the previou...
X-ray spectroscopy of Abell S1101 with Chandra, XMM-Newton and ROSAT: band-pass dependence of he temperature profile and soft excess emission
X-ray spectroscopy Chandra band-pass dependence temperature profile soft excess emission
2011/9/28
We present spatially-resolved spectroscopy of the galaxy cluster Abell S1101, also known as Sersic 159-03, with Chandra, XMM-Newton and ROSAT, and investigate the presence of soft X-ray excess emissio...
A shock front in the merging galaxy cluster Abell 754: X-ray and radio observations
the merging galaxy cluster Abell 754 X-ray radio observations
2011/1/11
We present new Chandra X-ray and Giant Meterwave Radio Telescope (GMRT) radio observations of the nearby merging galaxy cluster Abell 754. Our X-ray data confirm the presence of a shock front by obtai...
A2163: Merger events in the hottest Abell galaxy cluster II. Subcluster accretion with galaxy-gas separation
Galaxies clusters general – Galaxies intergalactic medium – X-rays galaxies clusters
2010/11/16
Located at z = 0.203, A2163 is a rich galaxy cluster with an intra-cluster medium (ICM) that exhibits extraordinary properties,including an exceptionally high X-ray luminosity, average temperature, an...
A Joint Chandra and XMM-Newton View of Abell 3158: Massive Off-Centre Cool Gas Clump As A Robust Diagnostic of Merger Stage
XMM-Newton Massive Off-Centre Cool Gas Clump Abell 3158
2010/3/8
By analysing the Chandra and XMM-Newton archived data of the nearby galaxy cluster Abell 3158, which was reported to possess a relatively regular, relaxed morphology in the X-ray band in previous work...
