Study of Polarized Emission in Radio Halos and Filaments in the SKA Telescopes Era

Valentina Vacca, Federica Govoni, Matteo Murgia +12

Synchrotron diffuse emission in merging galaxy clusters and along filaments connecting them demonstrates the presence of relativistic particles and magnetic fields in these environ…

The Atacama Cosmology Telescope: A Test of the Gravitational Force Law on Cosmological Scales Using the Kinematic Sunyaev-Zeldovich Effect

Patricio A. Gallardo, Kris Pardo, Oliver H. E. Philcox +38

The mean pairwise velocity of massive halos reflects the gravitational force law on cosmic scales. We combine cosmic microwave background intensity maps from the Atacama Cosmology…

Intracluster Medium Fluctuations on Scales up to 1 Mpc: A Combined eROSITA and SPT/Planck Analysis of Abell 3266

H. Saxena, A. Heinrich, J. Sayers +22

Galaxy clusters form through hierarchical assembly, where smaller substructures merge to build the largest gravitationally bound objects in the universe. These mergers, combined wi…

The thermal and kinematic Sunyaev-Zeldovich effect in galaxy clusters and filaments using multifrequency temperature maps of the cosmic microwave background: Abell 399--Abell 401 cluster pair case study

Ajay S. Gill, Yilun Guan, Adam D. Hincks +19

We present a multifrequency and multi-instrument methodology to study the physical properties of galaxy clusters and cosmic filaments using cosmic microwave background observations…

The Atacama Cosmology Telescope: Quantifying Atmospheric Emission above Cerro Toco

Thomas W. Morris, Elia Battistelli, Ricardo Bustos +17

At frequencies below 1 Hz, fluctuations in atmospheric emission in the Chajnantor region in northern Chile are the primary source of interference for bolometric millimeter-wave obs…
