Spectral imaging of X-COP galaxy clusters with the Sunyaev-Zel'dovich effect
Anna Silvia Baldi, Hervé Bourdin, Pasquale Mazzotta
The Sunyaev-Zel'dovich effect is the ideal probe for investigating the outskirts of galaxy clusters. To map this signal, we apply a spectral imaging technique which combines parame…
Detection of anti-correlation of hot and cold baryons in galaxy clusters
Arya Farahi, Sarah L. Mulroy, August E. Evrard +10
The largest clusters of galaxies in the Universe contain vast amounts of dark matter, plus baryonic matter in two principal phases, a majority hot gas component and a minority cold…
Spectral imaging of the thermal Sunyaev-Zel'dovich effect in X-COP galaxy clusters: method and validation
Anna Silvia Baldi, Hervé Bourdin, Pasquale Mazzotta +4
The imaging of galaxy clusters through the Sunyaev--Zel'dovich effect is a valuable tool to probe the thermal pressure of the intra-cluster gas, especially in the outermost regions…
Optical validation and characterization of \Planck\ PSZ2 sources at the Canary Islands observatories. I. First year of LP15 observations
A. Streblyanska, A. Aguado-Barahona, A. Ferragamo +5
Using telescopes at the Canary Island observatories, we conducted the long-term observational programme 128-MULTIPLE-16/15B (LP15), a large and complete optical follow-up campaign…
LoCuSS: Scaling relations between galaxy cluster mass, gas, and stellar content
Sarah L. Mulroy, Arya Farahi, August E. Evrard +13
We present a simultaneous analysis of galaxy cluster scaling relations between weak-lensing mass and multiple cluster observables, across a wide range of wavelengths, that probe bo…
