How the cool-core population transitions from galaxy groups to massive clusters: A comparison of the largest Magneticum simulation with eROSITA, XMM-Newton, Chandra and LOFAR observations
Justo Antonio Gonzalez Villalba, Klaus Dolag, Veronica Biffi
Our aim is to understand how the interplay between AGN feedback and merge processes can effectively turn cool-core galaxy clusters into hot-core clusters in the modern universe. Ad…
Euclid: Field-level inference of primordial non-Gaussianity and cosmic initial conditions
A. Andrews, J. Jasche, G. Lavaux +147
A primary target of the \Euclid space mission is to constrain early-universe physics by searching for deviations from a primordial Gaussian random field. A significant detection of…
Hydrogen intensity mapping with MeerKAT: Preserving cosmological signal by optimising contaminant separation
Isabella P. Carucci, José L. Bernal, Steven Cunnington +9
Removing contaminants is a delicate, yet crucial step in neutral hydrogen (HI) intensity mapping and often considered the technique's greatest challenge. Here, we address this chal…
Measuring our peculiar velocity from spectroscopic redshift surveys
Mohamed Yousry Elkhashab, Cristiano Porciani, Daniele Bertacca
Our peculiar velocity imprints a dipole on galaxy density maps derived from redshift surveys. The dipole gives rise to an oscillatory signal in the multipole moments of the observe…

We present the samples of galaxies and quasars used for DESI 2024 cosmological analyses, drawn from the DESI Data Release 1 (DR1). We describe the construction of large-scale struc…
DESI 2024 V: Full-Shape Galaxy Clustering from Galaxies and Quasars
A. G. Adame, J. Aguilar, S. Ahlen +195
We present the measurements and cosmological implications of the galaxy two-point clustering using over 4.7 million unique galaxy and quasar redshifts in the range divi…
Spherical bias on the 3D reconstruction of the ICM density profile in galaxy clusters
I. Veronesi, I. Bartalucci, E. Rasia +9
X-ray observations of galaxy clusters are routinely used to derive radial distributions of ICM thermdynamical properties such as density and temperature. However, observations allo…
CLASH-VLT: Galaxy cluster MACS J0329-0211 and its surroundings using galaxies as kinematic tracers
M. Girardi, W. Boschin, A. Mercurio +9
We aim to gain new insights into the controversial dynamical status of MACS J0329-0211 (MACS0329), a massive cluster at z=0.4503, with a new analysis using a large sample of member…
CHEX-MATE: the intracluster medium entropy distribution in the gravity-dominated regime
G. Riva, G. W. Pratt, M. Rossetti +26
We characterise the entropy profiles of 32 very high mass () galaxy clusters (HIGHMz), selected from the CHEX-MATE sample, to study the intracl…
Gravothermalizing into primordial black holes, boson stars, and cannibal stars
Pranjal Ralegankar, Daniele Perri, Takeshi Kobayashi
Very little is known about the cosmological history from after the end of inflation until Big Bang Nucleosynthesis. Various well-motivated models predict that the universe could ha…
The galaxy-IGM connection in THESAN: the physics connecting the IGM Lyman- opacity and galaxy density in the reionization epoch
Enrico Garaldi, Verena Bellscheidt, A. Smith +1
The relation between the Lyman- effective optical depth of quasar sightlines () and the distribution of galaxies around them is an emerging probe of the connecti…
Matter power spectrum induced by primordial magnetic fields: from the linear to the non-linear regime
Pranjal Ralegankar, Enrico Garaldi, Matteo Viel
Linear theory predicts that primordial magnetic fields (PMFs) enhance the matter power spectrum on small scales. However, the linear approximation breaks down on sufficiently small…
