SLOW IV: Not all that is Close will Merge in the End. Superclusters and their Lagrangian collapse regions
B. A. Seidel, K. Dolag, R. -S. Remus +4
Superclusters are the most massive structures in the universe. To what degree they are actually bound against an accelerating expansion of the background is of significant cosmolog…
The Thermal Sunyaev-Zel'dovich Effect from the Epoch of Reionization
Ilian T. Iliev, Azizah R. Hosein, Jens Chluba +11
The thermal Sunyaev-Zel'dovich (tSZ) effect arises from inverse Compton scattering of low energy photons onto thermal electrons, proportional to the integrated electron pressure, a…
Dispersion Measures of Fast Radio Bursts through the Epoch of Reionization
Joshua J. Ziegler, Paul R. Shapiro, Taha Dawoodbhoy +13
Dispersion measures (DM) of fast radio bursts (FRBs) probe the density of electrons in the intergalactic medium (IGM) along their lines-of-sight, including the average density vers…
Constraining Reionization with Lyα Damping-Wing Absorption in Galaxy Spectra: A Machine Learning Model Based on Reionization Simulations
Hyunbae Park, Intae Jung, Hidenobu Yajima +8
Recently, NIRSpec PRISM/CLEAR observations by JWST have begun providing rest-frame UV continuum measurements of galaxies at , revealing signatures of Ly damping-wing…
Dust-UV offsets in high-redshift galaxies in the Cosmic Dawn III simulation
Pierre Ocvirk, Joseph S. W. Lewis, Luke Conaboy +13
Recent observations have revealed puzzling spatial disparities between ALMA dust continuum and UV emission as seen by HST and JWST in galaxies at (e.g. ALPINE and REBELS su…
The Glow of Axion Quark Nugget Dark Matter: (II) Galaxy Clusters
Julian S. Sommer, Klaus Dolag, Ludwig M. Böss +8
(abridged) We analyze the emission of axion quark nuggets in a large sample of 161 simulated galaxy clusters using the SLOW simulation. These clusters are divided into a sub-sample…
Revisiting the large-scale CMB anomalies: The impact of the SZ signal from the Local Universe
Gabriel Jung, Nabila Aghanim, Jenny Sorce +3
The full sky measurements of the Cosmic Microwave Background (CMB) temperature anisotropies by and have highlighted the presence of several unexpe…
Euclid: Early Release Observations -- Dwarf galaxies in the Perseus galaxy cluster
F. R. Marleau, J. -C. Cuillandre, M. Cantiello +193
We make use of the unprecedented depth, spatial resolution, and field of view of the Euclid Early Release Observations of the Perseus galaxy cluster to detect and characterise the…
Euclid: Early Release Observations -- Overview of the Perseus cluster and analysis of its luminosity and stellar mass functions
J. -C. Cuillandre, M. Bolzonella, A. Boselli +199
The Euclid ERO programme targeted the Perseus cluster of galaxies, gathering deep data in the central region of the cluster over 0.7 square degree, corresponding to approximately 0…
Euclid: Early Release Observations -- Programme overview and pipeline for compact- and diffuse-emission photometry
J. -C. Cuillandre, E. Bertin, M. Bolzonella +260
The Euclid ERO showcase Euclid's capabilities in advance of its main mission, targeting 17 astronomical objects, from galaxy clusters, nearby galaxies, globular clusters, to star-f…
Euclid: Early Release Observations -- The intracluster light and intracluster globular clusters of the Perseus cluster
M. Kluge, N. A. Hatch, M. Montes +185
We study the intracluster light (ICL) and intracluster globular clusters (ICGCs) in the nearby Perseus galaxy cluster using Euclid's EROs. By modelling the isophotal and iso-densit…
Can the splashback radius be an observable boundary of galaxy clusters?
Théo Lebeau, Stefano Ettori, Nabila Aghanim +1
The splashback radius was proposed as a physically motivated boundary of clusters as it sets the limit between the infalling and the orbitally dominated regions. However, galaxy cl…
Simulating the LOcal Web (SLOW) II: Properties of local galaxy clusters
Elena Hernández-Martínez, Klaus Dolag, Benjamin Seidel +6
This is the second paper in a series presenting the results from a 500 Mpc large constrained hydro-dynamical simulation of the local Universe (SLOW). The initial conditions…
