Cosmological constraints from the Planck cluster catalogue with DES shear profiles and Chandra observations

G. Aymerich, S. Grandis, M. Douspis +50

We present cosmological constraints from the Planck PSZ2 cosmological cluster sample, using weak-lensing shear profiles from Dark Energy Survey (DES) data and X-ray observations fr…

Probing cluster magnetism with embedded and background radio sources in Planck clusters

Erik Osinga, Reinout J. van Weeren, Lawrence Rudnick +6

Magnetic fields remain an enigmatic part of the content of galaxy clusters. Faraday rotation and depolarisation of extragalactic radio sources are useful probes, but the limited av…

A complex node of the cosmic web associated with the massive galaxy cluster MACS J0600.1-2008

Lukas J. Furtak, Adi Zitrin, Johan P. Richard +18

MACS J0600.1-2008 (MACS0600) is an X-ray luminous, massive galaxy cluster at , studied previously by the REionization LensIng Cluster Survey (RELICS) and ALMA…

Cosmological constraints from the Chandra-Planck galaxy cluster sample

G. Aymerich, M. Douspis, G. W. Pratt +8

We provide a new scaling relation between , the integrated Sunyaev-Zeldovich signal and , the cluster mass derived from X-ray observations, u…

On the Particle Acceleration Mechanisms in a Double Radio Relic Galaxy Cluster, Abell 1240

Arnab Sarkar, Felipe Andrade-Santos, Reinout J. van Weeren +12

We present a 368 ks deep Chandra observation of Abell~1240, a binary merging galaxy cluster at a redshift of 0.195 with two Brightest Cluster Galaxies (BCGs) may have passed each o…

Reaching for the stars -- JWST/NIRSpec spectroscopy of a lensed star candidate at

Lukas J. Furtak, Ashish K. Meena, Erik Zackrisson +31

We present JWST/NIRSpec observations of a highly magnified star candidate at a photometric redshift of , previously detected in JWST/NIRCam imaging of t…
