A census of Dark Energy Survey Year 3 redMaPPer galaxy clusters in a high exposure eROSITA All Sky Survey region

P. A. Giles, A. K. Romer, J. Pilling +64

We present the cross-match of galaxy clusters detected by redMaPPer using the first three years of Dark Energy Survey (DESY3RM) operations, and the first release of the eROSITA-All…

Active galactic nucleus activity in brightest cluster galaxies at intermediate redshifts in Sunyaev-Zel'dovich--selected clusters

N. Hatamkhani, R. E. Skelton, J. Delhaize +4

Context. Brightest cluster galaxies (BCGs) host powerful active galactic nuclei (AGNs) and help regulate the heating--cooling balance of the intracluster medium. While radio-mode f…

The MeerKAT Massive Distant Clusters Survey: a search for diffuse radio emission in 30 massive SZ-selected clusters at

Dakalo G. Phuravhathu, M. Hilton, S. P. Sikhosana +10

We present the results of a search for diffuse radio emission in a uniformly selected sample of 30 of the most massive Sunyaev-Zel'dovich selected galaxy clusters at , provi…

A high-dynamic-range view of the growth of structure and the warm/hot Universe

Luca Di Mascolo, Tony Mroczkowski, Joshiwa van Marrewijk +23

Baryons heat to temperatures above as they accrete onto massive overdensities -- galaxies, groups, clusters, and filaments -- where they ionize and become o…

Weak Lensing Mass Calibration of the ACT DR5 Galaxy Clusters with the DES Year 3 Weak Lensing Data

T. Shin, E. J. Baxter, E. Lee +93

We use weak gravitational lensing measurements from Year 3 Dark Energy Survey data to calibrate the masses of 443 galaxy clusters selected via the Sunyaev-Zel'dovich effect from At…

An independent estimate of H(z) at z = 0.5 from the stellar ages of brightest cluster galaxies

S. Ilani Loubser, Adebusola B. Alabi, Matt Hilton +6

Several cosmological observations (e.g., Cosmic Microwave Background (CMB), Supernovae Type Ia, and local distance ladder measurements such as Cepheids) have been used to measure t…

The MeerKAT Massive Distant Clusters Survey: A Radio Halo in a Massive Galaxy Cluster at z = 1.23

S. P. Sikhosana, M. Hilton, G. Bernardi +9

In the current paradigm, high redshift radio halos are expected to be scarce due to inverse Compton energy losses and redshift dimming, which cause them to be intrinsically faint.…

A full reconstruction of two galaxy clusters intra-cluster medium with strong gravitational lensing

Joseph F. V. Allingham, Céline Bœhm, Dominique Eckert +6

Whilst X-rays and Sunyaev-Zel'dovich observations allow to study the properties of the intra-cluster medium (ICM) of galaxy clusters, their gravitational potential may be constrain…
