Recent advances toward mesoscopic quantum optomechanics
We present a number of approaches, currently in experimental development in our research groups, toward the general problem of macroscopic quantum mechanics, i.e., manifestations of quantum noise and quantum fluctations…
New CUPID-Mo results
The CUPID-Mo experiment has measured the two-neutrino double beta decay of the isotope Mo-100 with the highest precision ever in any double beta decay isotope. This results were presented at…
GRANDMA and HXMT Observations of GRB 221009A — the Standard-Luminosity Afterglow of a Hyper-Luminous Gamma-Ray Burst
GRB 221009A is the brightest Gamma-Ray Burst (GRB) detected in more than 50 years of study. In this paper, we present observations in the X-ray and optical domains after the…
Virgo Detector Characterization and Data Quality: results from the O3 run
The Advanced Virgo detector has contributed with its data to the rapid growth of the number of detected gravitational-wave (GW) signals in the past few years, alongside the two Advanced…
Virgo Detector Characterization and Data Quality: tools
Detector characterization and data quality studies -- collectively referred to as {\em DetChar} activities in this article -- are paramount to the scientific exploitation of the joint dataset collected by…
Analysis methods to localize and characterize X-ray sources with the Micro-channel X-ray Telescope on board the SVOM satellite
SVOM is a Sino-French space mission targeting high-energy transient astrophysical objects such as gamma-ray bursts. The soft X-ray part of the spectrum is covered by the Micro-channel X-ray Telescope (MXT)…
The gamma emission of a nova predicted in great detail
On August 8, 2021, a "new" star appeared in the constellation of Ophiuchus and remained visible to the naked eye for several days. In fact, it had already been observed…
Vincent Tatischeff: Silver CNRS medal 2022
Vincent Tatischeff, research director (A2C pole, Astrophysics & Cosmochemistry), was rewarded with the CNRS silver medal, given by Vincent Poireau (IN2P3 DAS), in the presence of Sophie Henrot-Versillé, A2C director.…
