** STEPHEN HAWKING WAS RIGHT ** Using a very strong black-hole merger signal, the @LIGO-@ego_virgo-@KAGRA_PR Collaboration has shown the 2nd law of black hole mechanics, Hawking's area law (A_final > A_initial), to hold with high credibility. PRL: go.aps.org/3VarXHA #open

Results from the first part of our fourth LIGO @ego_virgo @KAGRA_PR observing run are out today! We're pleased to share the largest catalog of gravitational-wave observations with more discoveries of black holes and neutron stars 📰 arxiv.org/abs/2508.18082 #O4IsHere #GWTC4

Exciting #GravitationalWave candidate from yesterday #S250114ax If real, the source is probably a binary black hole False alarm rate 1 in 7.7×10^18 yr GraceDB gracedb.ligo.org/superevents/S2… GCN gcn.nasa.gov/circulars/38932 Rating 🖤🪿🤝 #O4IsHere

Je finis avec une pensée de mon cher Hubert Reeves "L'homme mène un combat contre la nature, s'il le gagne, il est perdu". Menons donc un combat pour les faits... et ailleurs. Ce compte fermera le 20 janvier. Merci tout le monde

[MÉDAILLES D’HONNEUR] Mardi 19 novembre, Sylvain Di Giorgio, délégué régional de @CNRS Délégation Côte d’Azur, remettait les médailles d’honneur au personnel parti à la retraite ces dernières années, aux côtés des représentants des 18 laboratoires.

Artemis researcher contributed to the search for a GW signal emitted by #SN2023ixf in the @LIGO @ego_virgo @KAGRA_PR data. See arxiv.org/abs/2410.16565

It’s several folks from @ObsCoteAzur at the GdR for #GravitationalWaves talking about some of the cool science being done at @lab_artemis and in the LVK! It was great to mingle and chat science with the GW community in France 🇫🇷 @ego_virgo @LIGO @KAGRA_PR

Congratulations to @OMinazzoli who succesfully defended his Habilitation last week at the @ObsCoteAzur

Here are some folks from @ObsCoteAzur @lab_artemis with their posters at the LVK meeting this week! 🤩 Some cool science by Hugo Einsle and Marco Rivera (@MIBRivera) @ego_virgo @LIGO @KAGRA_PR #GravitationalWaves

On september 20th, Marco @MIBRivera and Rhida @ridha_mm_ have successfully graduated from the Erasmus Master in Astrophysics and Space Science (MASS) of the @Univ_CotedAzur. Congratulations! x.com/MIBRivera/stat…

Weizmann Kiendrebeogo successfully defended his PhD yesterday. Congrats Weizmann! @Univ_CotedAzur @Universite_JKZ @ObsCoteAzur

Kamiel Janssens et al paper on correlated and Newtonian noise impact on third generation GW detectors is published in PhysRevD journals.aps.org/prd/abstract/1…

Virgo is getting ready to join LIGO detectors for the second part of the O4 observing run! @ego_virgo @LIGOWA @LIGOLA

@OMinazzoli @scholarpedia ah ah!

Just realized my colleagues at @lab_artemis published an article on GW detectors on @scholarpedia last year without me knowing—even though I’m an editor there! 🤣😅 Been a bit inactive lately; might be time to resume my duties. scholarpedia.org/article/Gravit…
