CMBX Science Working Group updates

Carlo Baccigalupi, Giulio Fabbian, Stéphane Ilic

Introductory Remarks

The Cosmic Microwave Background Cross-Correlation Working Group (CMBXC WG) in Euclid has achieved significant milestones since the previous Consortium Meeting in Oslo. The team is now getting ready for analysis, starting with Data Release 1 (DR1). The group plans to exploit existing CMB Datasets – Planck in particular – and to provide support to the Consortium in connecting  with operating and future CMB observational campaigns. The activities of the group progress towards completion of the planned papers within the Key Projects (KPs) on (1) Simulations & Covariances, (2) Estimators, (3) Likelihood, and (4) Extended Forecasts, as described in the following. As the post-launch phase approaches, the group has been increasing its efforts in interfacing with the activities of the rest of the Consortium, in particular with regards to the Inter-Science Working Group Taskforce Likelihood (ISTL), as well as the Science Ground Segment (SGS).

The Euclid Science Performance Verification 3 meeting, March 2023

Authors: F. Bernardeau, P.-A. Frugier and H. Aussel (SPV3 leads)

From March 20 to March 23, a meeting dedicated to the third Science Performance Verification exercise (SPV3) took place at the Institut d’Astrophysique de Paris, France. Since the online kick-off meeting of the exercise, that took place in Feb. 17 2021, that was the first opportunity for key EC members of the SPV3 project to meet face to face. Unfortunately, in person participation was a bit hampered by the strike movements that affected Paris at that moment, but it was nonetheless a very lively meeting with up to 30 in person participants and about 10 to 20 online.

Euclid Consortium Galaxy Clustering Science Working Group meeting, Milan, February 2023

Authors: L. Guzzo, W. Percival & Y. Wang (GC-SWG leads)

Introduction & motivation

During the week of February 20-24, a meeting dedicated to the Galaxy Clustering (GC) measurements to be made by Euclid was held at the “Universitá Statale”, in Milan. This was the first in-person meeting focussed on galaxy clustering after 3 years of the pandemic break, and gathered together all units constituting the spectroscopic pipeline of Euclid, from the raw data to the cosmological parameter measurements. Participation was strong, with 90 people attending in person and an average of 20 connected remotely. Having an in-person joint meeting bringing together all steps along the data analysis chain, was a natural extension of the series of online meetings, which are now held every 2 weeks, bringing together managers and key personnel for the GC pipeline. There was much to review and to plan for, following a busy 2022, which included the Mission Key Point (MKP) review, and a focussed meeting on Observational Systematics organised at IFPU in Trieste.
