The QUBIC Collaboration welcomes Haochen Jiang and Noah Orazi, new members in the French group.

Haochen Jiang is a first year Masters student at Sorbonne University in Fundamental Physics. He’s originally from Tsing Tao in China. He did his Bachelor’s at Université Paris Cité and he will complete his Masters diploma this summer for the M1 Masters and go on next year with the M2, also at Sorbonne University, in the program of “Astronomy, Astrophysics, and Space Engineering”. He hopes to continue with a PhD after that. For his internship, he is working on QUBIC map making simulations, and in particular Haochen has made an important contribution in debugging the high frequency simulations for QUBIC.

Noah Orazi is master’s student in theoretical physics at Université Paris Cité and ENS Paris, focusing on cosmology and data analysis. He is currently doing an internship at the APC laboratory, working on reducing instrumental noise for the QUBIC telescope project. Outside his studies, he enjoy trail running, hiking, and playing the guitar.

Celestial Attraction (the 3-channel documentary ) and Ex Nihilo (exhibition)  were part of the Agathe Simon presentation between April and June 2026, with a premiere at the L’Estrade art space. QUBIC Collaboration was part of these creations, a bridge between art and science,

Agathe Simon’s exhibition Ex Nihilo presents the visions of three women on creation: an artist, a cosmologist, and a llama breeder. It unfolds around an immersive video installation that connects two contrasting territories: the hedged farmland of the Orne region and the Andean highlands. During her residency at L’esTRAde, Agathe Simon developed new pieces that revolve around this multi-screen installation. Inspired by the Athis-de-l’Orne region, she explores, through her philagnostic method, a dual approach to creation: the origins of the universe and the artistic process.

In March 2026 the Q-U Bolometer Interferometric for cosmology is giving his first steps to scan the Moon, the Galactic Plane and other objects of interest from Alto Chorrillos. The instrument is operating remotely, which is the result of the collaborative effort along 2025.

QUBIC is making progress on the calibration source, which will be installed in the tower in Alto Chorrillos in the coming days. A significant group of QUBIC Collaboration members are currently in Salta to complete this task with part of the staff of QUBIC in that city. The photo shows, from left to right, Hernán Ocampo and Alejandro Soliz (Argentina), Youssef Moulane (Morocco), Mattia Bianchessi (Italy), Aoife Flood and Sabrina Marwerde (Ireland) and Fabricio Rodíguez (at the bottom, Argentina). Weather permitting, they will be traveling up to Alto Chorrillos next week..

The cable carrier, designed and fabricated in Argentina, was recently installed in QUBIC. This represents a significant improvement for the operation of the instrument, which is nearly ready to begin data acquisition at Alto Chorrillos. The project was carried out by ITeDA staff members Luciano Ferreyra, Juan Geria, Daniel Gorbeña, and Lucía Sucunza, under the supervision of Pablo Strazzeri.

The School of Applied and Engineering Physics is an academic and research institute focused on physical sciences and innovation, affiliated with the Mohammed VI Polytechnic University (UM6P) in Morocco, and it is a formal member of QUBIC experiment, since September of 2025. Youssef Moulane (in the images with Jean-Christophe Hamilton), a research scientist in astronomy and astrophysics at the UM6P, will be Morocco’s representative.

UM6P is a forward-looking university committed to applied research and addressing African challenges, aiming to be a global leader in science and technology. Central to the School’s agenda is Cosmology: exploring the universe’s origin, structure, and evolution. By studying the Cosmic Microwave Background (CMB), dark matter, and gravitational waves, researchers tackle cutting-edge questions.

The team contributes with expertise in CMB data analysis, scan strategy optimization, and foreground modeling. The School benefits from highly skilled staff, robust computational infrastructure, and international collaborations. By combining theory, simulation, and instrumental innovation, the UM6P School aims to advance the scientific frontier and empower African researchers to answer the universe’s most fundamental questions.

Doctor en Física por el MIT, profesor de Física en la Universidad de Berkeley en California, galardonado, junto con John Mather, con el Premio Nobel de Física en octubre de 2006, falleció el 18 septiembre de 2025 en París. Su contribución al estudio de la radiación de fondo de microondas mediante el satélite artificial COBE demostró que poco después del Big Bang existían en el Universo irregularidades que fueron la base para la formación de las galaxias.

Jean-Christophe Hamilton was named to be the new director of APC (Astroparticles and Cosmology) Laboratory located at Université Paris-Diderot. With this new responsibility,
he hands over his duties as Spokesperson of QUBIC to Michel Piat, who was unanimously voted in for this position by the QUBIC Collaboration Board.

Jean-Christophe keeps the collaboration motivated, he has brought significant funding to the project, and he is a major contributor to development efforts for data analysis, simulations, and
also for running the instrument and he has been the Principle Investigator/Spokesperson for QUBIC since the creation of the collaboration in 2008 which brought together the BRAIN and MBI collaborations. In his future role as director of APC, he will continue to support and promote QUBIC.

This project, supported by “Orillas Nuevas ~ Nouveaux Rivages” a program for Argentina’s cultural and creative industries (ICC), promoted by the Institut français d’Argentine, thanks to the exceptional support of the French Ministry of Europe and Foreign Affairs, takes as its trigger one of the biggest problems in physics: the reconciliation between general relativity, which answers questions of astronomical dimensions and masses, and quantum mechanics, which solves problems at the subatomic level, giving rise to what is known as “The Problem of the Two Infinite.”.

C’est avec une profonde tristesse que nous disons adieu à notre collègue Yannick Giraud-Héraud, décédé le 13 juin 2025. Depuis 1999, il a œuvré sans relâche à la création du laboratoire Astroparticules et Cosmologie (APC), dont il était l’un des fondateurs. En janvier 2005, il a pris la tête du groupe Cosmologie et Gravitation. Il a largement contribué à positionner l’APC comme un acteur majeur, notamment par sa participation à la mission spatiale Planck de l’ESA, qu’il a coordonnée pour l’IN2P3.
