The first astrophysical result of HISAKI: a search for the EUV He I lines a massive cool core cluster at z=0.7
Yuanyuan Su, Tomoki Kimura, Ralph Kraft +6
Molecular cold gas and star formation have been observed at centers of cool-core clusters, albeit at a level much smaller than expected from the classic cooling model. Feedback fro…
Characterisation of the Particle-Induced Background of XMM-Newton EPIC-pn: Short and Long Term Variability
Esra Bulbul, Ralph Kraft, Paul Nulsen +16
The particle-induced background of X-ray observatories is produced by Galactic Cosmic Ray (GCR) primary protons, electrons, and He ions. Events due to direct interaction with the d…
Detection of Superluminal Motion in the X-Ray Jet of M87
Bradford Snios, Paul E. J. Nulsen, Ralph P. Kraft +5
Chandra HRC observations are investigated for evidence of proper motion and brightness changes in the X-ray jet of the nearby radio galaxy M87. Using images spanning 5 yr, proper m…
Extended X-ray study of M49: the frontier of the Virgo Cluster
Y. Su, R. P. Kraft, P. E. J. Nulsen +10
The M49 group, resident outside the virial radius of the Virgo cluster, is falling onto the cluster from the south. We report results from deep {\sl XMM-Newton} mosaic observations…
Astro2020 Science White Paper: A Unification of the Micro and Macro Physics in the Intracluster Medium of Nearby Clusters
Y. Su, R. Kraft, E. Roediger +9
Clusters of galaxies are the most massive virialized structures in the Universe. The microphysical properties of the intracluster plasma can affect dynamical processes over an enor…
Evidence for a TDE origin of the radio transient Cygnus A-2
Martijn N. de Vries, Michael W. Wise, Paul E. J. Nulsen +3
In 2015, a radio transient named Cygnus A-2 was discovered in Cygnus A with the Very Large Array. Because of its radio brightness ( erg s), th…
Supermassive Black Hole Feedback
Mateusz Ruszkowski, Daisuke Nagai, Irina Zhuravleva +23
Understanding the processes that drive galaxy formation and shape the observed properties of galaxies is one of the most interesting and challenging frontier problems of modern ast…
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…
Unveiling the Galaxy Cluster - Cosmic Web Connection with X-ray observations in the Next Decade
Stephen A. Walker, Daisuke Nagai, A. Simionescu +35
In recent years, the outskirts of galaxy clusters have emerged as one of the new frontiers and unique laboratories for studying the growth of large scale structure in the universe.…
Powerful AGN jets and unbalanced cooling in the hot atmosphere of IC 4296
R. Grossová, N. Werner, K. Rajpurohit +13
We present new Karl G. Jansky Very Large Array (VLA, 1.5 GHz) radio data for the giant elliptical galaxy IC 4296, supported by archival radio, X-ray (Chandra, XMM-Newton) and optic…
A New Class of X-Ray Tails of Early-Type Galaxies and Subclusters in Galaxy Clusters - Slingshot Tails vs Ram Pressure Stripped Tails
Alex Sheardown, Thomas M. Fish, Elke Roediger +11
We show that there is a new class of gas tails - slingshot tails - which form as a subhalo (i.e. a subcluster or early-type cluster galaxy) moves away from the cluster center towar…
Driving massive molecular gas flows in central cluster galaxies with AGN feedback
H. R. Russell, B. R. McNamara, A. C. Fabian +7
We present an analysis of new and archival ALMA observations of molecular gas in twelve central cluster galaxies. We examine emerging trends in molecular filament morphology and ga…
Variability and Proper Motion of X-ray Knots in the Jet of Centaurus A
Bradford Snios, Sarka Wykes, Paul E. J. Nulsen +8
We report results from Chandra observations analyzed for evidence of variability and proper motion in the X-ray jet of Centaurus A. Using data spanning 15 years, collective proper…
