The Simons Observatory: forecasted constraints on primordial gravitational waves with the expanded array of Small Aperture Telescopes
The Simons Observatory Collaboration, I. Abril-Cabezas, S. Adachi +479
We present updated forecasts for the scientific performance of the degree-scale (0.5 deg FWHM at 93 GHz), deep-field survey to be conducted by the Simons Observatory (SO). By 2027,…
CHEX-MATE: towards a consistent universal pressure profile and cluster mass reconstruction
M. Muñoz-Echeverría, E. Pointecouteau, G. W. Pratt +31
In a self-similar paradigm of structure formation, the thermal pressure of the hot intra-cluster gas follows a universal distribution once the profile of each cluster is normalised…
Deriving accurate galaxy cluster masses using X-ray thermodynamic profiles and graph neural networks
Asif Iqbal, Subhabrata Majumdar, Elena Rasia +4
Precise determination of galaxy cluster masses is crucial for establishing reliable mass-observable scaling relations in cluster cosmology. We employ graph neural networks (GNNs) t…
Thermal Sunyaev-Zel'dovich effect at the core of CL J1226.9+3332 revealed by NOEMA
M. Muñoz-Echeverría, J. -F. Macías-Pérez, R. Neri +58
We present first detailed maps of the thermal Sunyaev-Zel'dovich (tSZ) effect on a cluster with the NOrthern Extended Millimeter Array (NOEMA). The high sensitivity of t…
NIKA2 Cosmological Legacy Survey: Blind detection of galaxy clusters in the COSMOS field via the Sunyaev-Zel'dovich effect
D. Chérouvrier, J. F. Macias-Perez, F. X. Désert +59
(Abridged) Clusters of galaxies, formed in the latest stages of structure formation, are unique cosmological probes. With the advent of large CMB surveys like those from the Planck…
Euclid Quick Data Release (Q1) -- Data release overview
Euclid Collaboration, H. Aussel, I. Tereno +407
The first Euclid Quick Data Release, Q1, comprises 63.1 sq deg of the Euclid Deep Fields (EDFs) to nominal wide-survey depth. It encompasses visible and near-infrared space-based i…
