QUBIC Observatory inaugurated in Argentina

On Wednesday 23 November 2022, the QUBIC Observatory was inaugurated in Argentina. Located in Alto Chorrilos, at an altitude of 5000m, this observatory will allow the observation of the Cosmic Microwave Background (CMB) and in particular the polarisation of its B modes.

The main actors of this project were present for this inauguration: the national and provincial authorities of Argentina, many members of the international collaboration QUBIC including those of the APC.
Our laboratory was represented by Jean-Christophe Hamilton (spokesman for the QUBIC collaboration), Antoine Kouchner and Florence Ardellier (management team), Michel Piat (QUBIC Instrument Scientist), Fabrice Voisin and Damien Prêle (cryogenic electronics development), Steve Torchinsky (Calibration manager and vice-operation manager), Stéphane Dheilly (mechanical engineering) Pierre Chanial (data analysis), Mathias Régnier (PhD student).

The instrument will be cooled and commissioned in the coming weeks, before taking data from the sky. During this data collection, an increase in the sensitivity of the instrument will be prepared (addition of bolometric detectors).
