The impact of our peculiar motion on primordial non-Gaussianity measurements using the LIGER4GAL framework
Bartolomeo Bottazzi Baldi, Mohamed Yousry Elkhashab, Daniele Bertacca +1
Current and forthcoming galaxy surveys will map the observable Universe with unprecedented depth, sky coverage, and precision. These maps are affected by relativistic redshift-spac…
Environmental Quenching of High-Redshift Galaxies: Interpreting JWST Observations with Simulations
Aleyna Döven, Aleyna Döven, Mohammadreza Ayromlou +1
Recent observations of the high-redshift Universe, particularly with JWST, have revealed a population of quenched galaxies that challenges current galaxy formation models, which sy…
Coverage is not enough: Frequentist tests of simulation-based inference for primordial non-Gaussianity
Toka Alokda, Cristiano Porciani, Alexander Eggemeier
(Abridged) Simulation-based inference (SBI) has emerged as a powerful framework for extracting cosmological information from complex, non-linear data where analytical likelihoods a…
Probing the warm dark matter mass with [C II] intensity mapping
Elena Marcuzzo, Cristiano Porciani, Emilio Romano-DÃaz +3
The nature of dark matter (DM) is still debated. While cold DM (CDM) is the standard paradigm, warm DM (WDM) may ease some small-scale tensions in the CDM framework. Line-inten…
Euclid Quick Data Release (Q1): Euclid spectroscopy of quasars. 1. Identification and redshift determination of 3500 bright quasars
Euclid Collaboration, Y. Fu, R. Bouwens +354
The slitless spectroscopy mode of the NISP onboard Euclid has enabled efficient spectroscopy of objects within a large FoV. We present a large and homogeneous sample of bright quas…
Euclid preparation. Galaxy 2-point correlation function modelling in redshift space
Euclid Collaboration, M. Kärcher, M. -A. Breton +309
The Euclid satellite will measure spectroscopic redshifts for tens of millions of emission-line galaxies. In the context of Stage-IV surveys, the 3-dimensional clustering of galaxi…
