recommendations! Published in 2019 at "Astronomy and Astrophysics"

DOI: 10.1051/0004-6361/201936919

Abstract: The Planck collaboration has extensively used the six Planck HFI frequency maps to detect the Sunyaev-Zel'dovich (SZ) effect with dedicated methods, e.g., by applying (i) component separation to construct a full sky map of the… read more here.

DOI: 10.1093/mnras/staa3782

Abstract: A complete census of baryons in the late Universe is a long-standing challenge due to the intermediate temperate and rarefied character of the majority of cosmic gas. To gain insight into this problem, we extract… read more here.

DOI: 10.1093/mnras/stab2720

Abstract: Gas infalling into the gravitational potential wells of massive galaxy clusters is expected to experience one or more shocks on its journey to becoming part of the intracluster medium (ICM). These shocks are important for… read more here.

DOI: 10.1093/mnras/stx3362

Abstract: We present the measurement of the kinematic Sunyaev-Zel'dovich (kSZ) effect in Fourier space, rather than in real space. We measure the density-weighted pairwise kSZ power spectrum, the first use of this promising approach, by cross-correlating… read more here.

DOI: 10.1103/kclp-x5j1

Abstract: Recent advances in cosmological observations have provided an unprecedented opportunity to investigate the distribution of baryons relative to the underlying matter. In this work, we show that the gas is more extended than the dark… read more here.

DOI: 10.1103/lqbj-wcqj

Abstract: The gas density profile around galaxies, shaped by feedback and affecting the galaxy lensing signal, is imprinted on the cosmic microwave background (CMB) by the kinematic Sunyaev-Zel'dovich effect (kSZ). We precisely measure this effect ($S/N\approx… read more here.

DOI: 10.1103/physrevd.100.083522

Abstract: Observational cosmology has become an important laboratory for testing General Relativity, with searches for modified gravity forming a significant portion of the science case for existing and future surveys. In this paper, we illustrate how… read more here.

recommendations! Published in 2022 at "Physical Review D"

DOI: 10.1103/physrevd.105.083503

Abstract: Recent measurements from the CMB and from high-redshift galaxy observations have placed rough constraints on the midpoint and duration of the Epoch of Reionization. Detailed measurements of the ionization history remain elusive, although two proposed… read more here.

DOI: 10.1103/physrevd.109.123525

Abstract: We demonstrate that pairwise peculiar velocity correlations for galaxy clusters can be directly reconstructed from the kinematic Sunyaev-Zel'dovich (kSZ) signature imprinted in the CMB using a machine learning model with a gradient boosting algorithm trained… read more here.
