Gas sloshing and cold fronts in pre-merging galaxy cluster Abell 98
Arnab Sarkar, Scott Randall, Yuanyuan Su +10
We present deep Chandra observations of the pre-merger galaxy cluster Abell 98. Abell 98 is a complex merging system. While the northern (A98N) and central subclusters (A98S) are m…
Discovery of a pre-merger shock in an intercluster filament in Abell 98
Arnab Sarkar, Scott Randall, Yuanyuan Su +11
We report the first unambiguous detection of an axial merger shock in the early-stage merging cluster Abell 98 using deep (227 ks) Chandra observations. The shock is about 420 kpc…
Suzaku Observations of the Cluster Outskirts and Intercluster Filament in the Triple Merger Cluster Abell 98
Gabriella E. Alvarez, Scott W. Randall, Yuanyuan Su +5
We present Suzaku observations of the Abell 98 (A98) triple galaxy cluster system and the purported intercluster filament. The three subclusters are expected to lie along a large s…
Probing Macro-Scale Gas Motions and Turbulence in Diffuse Cosmic Plasmas
Esra Bulbul, Massimo Gaspari, Gabriella Alvarez +31
Clusters of galaxies, the largest collapsed structures in the Universe, are located at the intersection of extended filaments of baryons and dark matter. Cosmological accretion ont…
Chandra and XMM-Newton Observations of the Abell 3391/Abell 3395 Intercluster Filament
Gabriella E. Alvarez, Scott W. Randall, Herve Bourdin +2
We present Chandra and XMM-Newton X-ray observations of the Abell 3391/Abell 3395 intercluster filament. It has been suggested that the galaxy clusters Abell 3395, Abell 3391, and…
Orbital Solutions and Absolute Elements of the W UMa Binary MW Pavonis
Gabriella E. Alvarez, James R. Sowell, Richard M. Williamon +1
We present differential photoelectric photometry obtained by Williamon of the short-period A-type W~UMa binary MW~Pav. With the Wilson-Devinney analysis program we obtained a…
