100. Baryon Pasting Project

Daisuke Nagai (Yale University)

28/06/2023 09:00

In this talk, I will present the Baryon Pasting project, which aims to develop a physically-motivated, computationally efficient model for large multi-wavelength cosmological surveys (including microwave, X-ray and optical skies). I will discuss the current status, challenges, and future prospects of forward-modeling multi-wavelength cosmological surveys and enabling cross-survey,...

80. Towards accurate millimeter-wave sky maps from gravity-only simulations

Florian Kéruzoré (Argonne National Laboratory)

Galaxy cluster-based cosmology is at a crossroads, with the current and next-generation surveys delivering deep sky surveys and large cluster catalogs. In this framework, the use of simulations to calibrate systematics in cosmological analyses is crucial. As a large proportion of cosmological simulations are gravity-only (effectively only evolving dark matter particles), the exploitation of...

75. The high-resolution 300 clusters

Weiguang Cui (UAM)

28/06/2023 09:55

Building upon the success of the300 galaxy cluster project, I will present our current efforts on simulating the same clusters but with an order of magnitude higher resolution, which is crucial to (1) understand the galaxy cluster evolution in detail; (2) match the capability of the upcoming telescopes.
With the updated SIMBA-C model which has improvements in several aspects, especially a...

9. The Cluster XMM-Heritage project CHEX-MATE: current results and future prospects

Stefano Ettori (INAF-Osservatorio di Astrofisica e Scienza dello Spazio in Bologna)

28/06/2023 11:00

The Cluster HEritage project with XMM-Newton – Mass Assembly and Thermodynamics at the Endpoint of structure formation (CHEX-MATE)
is a three-mega-second Multi-Year Heritage Programme to obtain X-ray observations of a minimally-biased, signal-to-noise-limited sample of 118 galaxy clusters detected by Planck through the Sunyaev–Zeldovich effect. The program aims to study the ultimate products...

72. X-ray absorption and molecular content of the interstellar medium toward CHEX-MATE galaxy clusters

Herve Bourdin (University of Rome "Tor vergata")

28/06/2023 11:30

The X-ray spectrum of extragalactic sources, such as galaxy clusters, is affected by the photo-absorption of various components of the Galactic InterStellar Medium (ISM). The resulting spectral distortion contributes to the systematics of cluster temperature measurements. It essentially depends on the total (atomic+molecular) Galactic hydrogen density column, N_H, which remains challenging to...
