SZ-X-ray Surface Brightness Fluctuations in the SPT-XMM clusters
Charles Romero, Massimo Gaspari, Gerrit Schellenberger +10
The hot plasma in galaxy clusters, the intracluster medium (ICM), is expected to be shaped by subsonic turbulent motions, which are key for heating, cooling, and transport mechanis…
Probing the high frequency variability of NGC 5044: the key to AGN feedback
Gerrit Schellenberger, Ewan O'Sullivan, Laurence David +10
The active galactic nucleus (AGN) feeding and feedback process in the centers of galaxy clusters and groups is still not well understood. NGC 5044 is the ideal system in which to s…
A Deep Dive into the NGC 741 Galaxy Group: Insights into a Spectacular Head-Tail Radio Galaxy from VLA, MeerKAT, uGMRT and LOFAR
K. Rajpurohit, E. O'Sullivan, G. Schellenberger +17
We present deep, wideband multifrequency radio observations (144 MHz8 GHz) of the remarkable galaxy group NGC 741, which yield crucial insights into the interaction between the…
Examining the local Universe isotropy with galaxy cluster velocity dispersion scaling relations
A. Pandya, K. Migkas, T. H. Reiprich +7
In standard cosmology, the late Universe is assumed to be statistically homogeneous and isotropic. However, a recent study based on galaxy clusters by Migkas et al. (2021, arXiv:21…
Closing Pandora's Box -- The deepest X-ray observations of Abell 2744 and a multi-wavelength merger picture
Urmila Chadayammuri, Ákos Bogdán, Gerrit Schellenberger +1
Abell 2744, also known as Pandora's Cluster, is a complex merging galaxy cluster. While a major merger is clear along the north-south axis, the dynamical state of the northwest sub…
Active Galaxy Science with the Line Emission Mapper: The Case for High-Resolution Soft X-ray Spectroscopy
Kimberly A. Weaver, Jenna M. Cann, Ryan W. Pfeifle +11
This white paper discusses the breadth of science related to active galactic nuclei (AGN) and associated phenomena to be enabled by a mission with microcalorimeter energy resolutio…
