Astrocent becomes the new international institute of the Polish Academy of Sciences
On February 17, 2025, the Polish Academy of Sciences officially established the International Institute for Particle Astrophysics, which operates under the name Astrocent. Based in Warsaw, it is the first institute in Central and Eastern Europe entirely dedicated to particle astrophysics. The APC Laboratory, a partner of Astrocent, will play an important role in this project, whose development is supported by €30 million in European and national funding.

Svom Observes a Thermonuclear Explosion on a Neutron Star

Shortly after the start of its scientific operations, the SVOM space mission demonstrated its full potential by detecting a spectacular phenomenon: a thermonuclear X-ray burst from the celestial source 4U 0614+091. This observation marks an important milestone for the mission, showing its ability to study not only distant gamma-ray bursts, but also violent phenomena occurring within our own Galaxy.

Theses 2026: discover the topics proposed by the APC

The Astroparticle and Cosmology Laboratory (APC) is opening its doors to future doctoral students. Thesis topics for 2026, led by the laboratory's research teams, are now available here and cover a wide range of topics related to the physics of the two infinities: high-energy astrophysics, cosmology, particle physics, gravitational waves, and theoretical physics. Interested candidates are invited to contact the person listed for each proposal.

The Astroparticle & Cosmology Laboratory welcomes a Franco-Polish ministerial delegation
On December 3, 2025, the Astroparticle & Cosmology Laboratory welcomed a Polish delegation led by Prof. Andrzej Szeptycki, Undersecretary of State at the Polish Ministry of Science and Higher Education. This visit was part of the 8th Franco-Polish Forum for Science and Innovation. It comes at a pivotal moment: the signing of an agreement between the CNRS and the Polish Academy of Sciences, aimed at strengthening the partnership between the APC and the future International Institute for Particle Astrophysics (AstroCeNT).
