4. The ESA Euclid mission: from dreams to reality

Dr Pablo Fosalba (Institute of Space Sciences (ICE-CSIC, IEEC))

Oral Talk

I shall describe the ESA Euclid mission, from its adoption by ESA in 2011 to its current status. I will provide an overview of its capabilites, scientific goals and the coordinated effort undertaken by the collaboration to deliver the upcoming first Data Release (DR1).

86. Cosmology Likelihood for Observables in Euclid

Prof. Shahab Joudaki (CIEMAT, Spain), Shahab Joudaki (CIEMAT)

Oral Talk

I will provide a description of the code implementation and structure of Cosmology Likelihood for Observables in Euclid (CLOE), developed by members of the Euclid Consortium. CLOE is a modular Python code for computing the theoretical predictions of cosmological observables and evaluating them against state-of-the-art data from galaxy surveys such as Euclid in a unified likelihood. This...

68. Detecting gravitational wave-galaxy cross-correlations

Oral Talk

Gravitational waves (GWs) are emerging as a potentially powerful probe of the Universe on large scales. Notably, they may contribute in the coming years to addressing the Hubble tension, as both the number of observed GW events increases and the capacity of current detectors to localise their sources improves. In this talk, I will discuss a new method for measuring the Hubble constant using...

41. Cosmology with LVK Dark Sirens and Euclid latest catalogs available

Sarah FERRAIUOLO (AMY&Sapienza)

11/09/2026, 17:15

Oral Talk

We present a study aimed at using the galaxy catalog released by Euclid for Gravitational-wave (GW) cosmology. I will firstly present an overview of the galaxy catalogs released and planned to be released with Euclid, focusing on their overlap with current GW detections. We identified six candidate events with significant spatial overlap with Euclid. I then focus on presenting the...

83. Cosmological and astrophysical aspects of 21 cm intensity mapping surveys

Camila Novaes (Instituto Nacional de Pesquisas Espaciais)

11/09/2026, 17:30

Oral Talk

Intensity mapping (IM) of the redshifted 21 cm line emission from neutral hydrogen is an efficient technique for surveying the large-scale structure of the Universe. In this talk, I discuss cosmological and astrophysical aspects of 21 cm IM, addressing instrumental limitations that affect clustering measurements, the role of cross-correlations between radio and photometric galaxy surveys, and...
