Les rencontres TS2020+ (financées par le PNHE) rassemblent de manière régulière les chercheurs et les chercheuses de la communauté française d’étude multi-longueurs d’onde et multi-messagers du ciel variable et transitoire. In this talk, we will presen tthe GRANDMA kilonovae program with FINK,Īnd its application within the citizen science program with observations ![]() Specifically designed for the Rubin Observatory. This program is jointly operated with the Fink broker, Kilonovae candidates produced by public optical surveys such as the Zwicky The Multi-messenger Addicts (GRANDMA), to follow-up and characterize While the GW-detectors are off, we haveĭeveloped a program within the Global Rapid Advanced Network Devoted to Of the binary neutron star scenario, many open questions remain.Īnswering these questions requires early observations, well-sampled light curvesĪnd spectra of kilonovae. Gravitational waves led to groundbreaking results in our understanding The combination of electromagnetic and gravitational-wave data providesĪ unique opportunity to study the evolution of compact binary systems.Īlthough the kilonova detection AT2017gfo in association with A très basse énergie (MeV), le nouveau module optique segmenté permet à KM3NeT d’être un excellent détecteur de supernova (à effondrement de coeur), ce monitoring du ciel est déjà en operation depuis quelques années prêt pour la prochaine supernova galactique. La construction va continuer régulièrement dans les prochaines années. Dans quelques jours, des opérations en mer sont prévues sur les 2 sites pour doubler la taille des 2 détecteurs. Dans cette configuration réduite, on atteint une sensibilité instantanée similaire voir meilleure qu'ANTARES sur toute la gamme en énergie. A l’heure actuelle, 6 lignes de détection sont en operation sur les deux sites de KM3NeT. ![]() Aprés avoir fait un petit panorama des principaux résultats actuels, je vous montrerais ce qu’on peut faire avec KM3NeT, la prochaine génération de télescope à neutrino dans la Méditerranée. IceCube et ANTARES ont détectés le flux diffus de neutrinos de haute énergie et commencent à voir les premieres évidences des sources de ces neutrinos. Resulting consequences for compact star physics. In this talk I will concentrate on microphysicsĪnd present some examples of recent advances in the modeling and the Transport coefficients, neutrino reaction rates), or the influence of Open, among others on microphysics properties (equation of state, Understanding of these exciting observations will be achieved only Others the imprint of dense matter properties. Multi-messenger observations include the possibility of a galacticĬore-collapse supernova, where the GW and neutrino signal carry among Nuclear matter in neutron stars and the structure of these compact Network sensitivity will be further increased making this rapidlyĮvolving new astronomy challenge our understanding of hot and dense Star merger (GW170817) by the LIGO-Virgo collaboration together withĪn electromagnetic counterpart has brilliantly given birth to The first detection of gravitational waves (GWs) from a binary neutron Fink opens a new way of combining data from LSST and other time-domain surveys and will be key for analyses ranging from transient astrophysics to cosmology. Within minutes, Fink is able to communicate these candidates to teams and follow-up facilities. Fink enables the selection of promising transients by providing preliminary classifications and combining information from multiple channels (both surveys and catalogues). I will introduce Fink, a broker developed on high-end technology and designed for fast and efficient analysis of big data streams. The key to use this stream is to be able to select promising transients and to automatically connect with multi wavelength facilities. VRO public alert stream will communicate the detection of millions of potential transient objects every night. ![]() LSST is designed to address four science areas: probing dark energy and dark matter, taking an inventory of the solar system, exploring the transient optical sky and mapping the Milky Way. During the next decade, VRO will obtain high-resolution optical images of the Southern Sky at unprecedented depths. In this talk, I will present the Vera Rubin Observatory Legacy Survey of Space and Time (VRO LSST).
