Dark and Luminous Matter in the Coma Cluster: Probing Galaxy Cluster Assembly Through Filaments with Weak Lensing and Multiwavelength Observations
K. HyeongHan, K. Finner, M. James Jee +11
The Coma cluster (Abell 1656; ) is a nearby rich galaxy cluster and a key laboratory for studying cluster assembly in the Cosmic Web. We characterize its projected dark ma…
Non-thermal filaments and AGN recurrent activity in the galaxy group Nest200047: a LOFAR, uGMRT, MeerKAT, VLA radio spectral analysis
M. Brienza, K. Rajpurohit, E. Churazov +15
Nest200047 is a clear example of multiple radio bubbles from an Active Galactic Nucleus (AGN) in a galaxy group, featuring non-thermal filaments likely shaped by buoyancy, gas moti…
Radio-continuum spectra of ram pressure stripped galaxies in the Coma Cluster
I. D. Roberts, R. J. van Weeren, D. V. Lal +7
We used the nearby Coma Cluster as a laboratory in order to probe the impact of ram pressure on star formation as well as to constrain the characteristic timescales and vel…
ComPACT: ACT+Planck galaxy cluster catalogue
S. Voskresenskaia, A. Meshcheryakov, N. Lyskova
Galaxy clusters are the most massive gravitationally bound systems consisting of dark matter, hot baryonic gas and stars. They play an important role in observational cosmology and…
High-resolution, High-sensitivity, Low-frequency uGMRT View of Coma Cluster of Galaxies
D. V. Lal, N. Lyskova, C. Zhang +12
We present high-resolution, high-sensitivity upgraded Giant Metrewave Radio Telescope observations of the Coma cluster (A1656) at 250-500 MHz and 550-850 MHz. At 250-500 MHz, 135 s…
Runaway Merger Shocks in Galaxy Cluster Outskirts and Radio Relics
Congyao Zhang, Eugene Churazov, William R. Forman +1
Moderately strong shocks arise naturally when two subclusters merge. For instance, when a smaller subcluster falls into the gravitational potential of a more massive cluster, a bow…
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…
