Deep multimessenger search for compact binary mergers in LIGO, Virgo and Fermi/GBM data from 2016-2017
GW170817 - GRB 170817A provided the first observation of gravitational waves from a neutron star merger with associated transient counterparts across the entire electromagnetic spectrum. This discovery demonstrated the long-hypothesized…

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…
