Missing thermal energy of the intracluster medium
, 2007 The Sunyaev-Zel'dovich (SZ) effect is a direct probe of thermal energy content of the Universe, induced in the cosmic microwave background (CMB) sky through scattering of CMB photons off hot electrons in the intracluster medium (ICM). We report a 9-sigma

Intracluster medium of the merging cluster Abell 3395
, 2011 We present a detailed imaging and spectral analysis of the merging environment of the bimodal cluster A3395 using X-ray and radio observations. X-ray images of the cluster show five main constituents of diffuse emission : A3395 NE, A3395 SW, A3395 NW ...

EDA Complex-Driven Desaturation of Heterocyclic Carbonyl Compounds Enabled by HFIP. [PDF]
Angew Chem Int Ed EnglIn this work, we report a novel light‐mediated desaturation strategy enabled by electron donor–acceptor complex formation. DFT and mechanistic studies reveal that the reaction proceeds via single‐electron transfer, hydrogen atom transfer, and base‐mediated deprotonation sequentially with pyridinium salt serving dually as oxidant and base, and ...

Witnessing the intracluster medium assembly at the cosmic noon in JKCS 041 [PDF]
Monthly notices of the Royal Astronomical Society, 2023 In this work we study the intracluster medium of a galaxy cluster at the cosmic noon: JKCS 041 at z = 1.803. A 28h long Sunyaev-Zel’dovich (SZ) observation using MUSTANG-2 allows us to detect JKCS 041 , even if intrinsically extremely faint compared to

Life cycle of cosmic-ray electrons in the intracluster medium [PDF]
Astronomy & Astrophysics, 2022 We simulate the evolution of relativistic electrons injected into the medium of a small galaxy cluster by a central radio galaxy, studying how the initial jet power affects the dispersal and the emission properties of radio plasma.

Simulating the transport of relativistic electrons and magnetic fields injected by radio galaxies in the intracluster medium [PDF]
Astronomy & Astrophysics, 2021 Radio galaxies play an important role in the seeding of cosmic rays and magnetic fields in galaxy clusters. Here, we simulate the evolution of relativistic electrons injected into the intracluster medium by radio galaxies.

On the Small-scale Turbulent Dynamo in the Intracluster Medium: A Comparison to Dynamo Theory [PDF]
Astrophysical Journal, 2021 We present non-radiative, cosmological zoom-in simulations of galaxy-cluster formation with magnetic fields and (anisotropic) thermal conduction of one massive galaxy cluster with M vir ∼ 2 × 1015 M ⊙ at z ∼ 0.

Turbulence in stratified atmospheres: implications for the intracluster medium [PDF]
Monthly notices of the Royal Astronomical Society, 2020 The gas motions in the intracluster medium (ICM) are governed by turbulence. However, since the ICM has a radial profile with the centre being denser than the outskirts, ICM turbulence is stratified.
