    Invited Talk

    Over the recent years there has been a concerted effort to directly measure the s process neutron source cross section in the deep-underground environment of the Gran Sasso National Laboratory as part of the LUNA collaboration's experimental program. Using the 400 kV LUNA II accelerator and exploiting the ultra-low background conditions, the main s process neutron source $^{13}$C$(\alpha,...

    Invited Talk

    The Jinping Underground experiment for Nuclear Astrophysics (JUNA) takes advantage of the ultra-low background of the CJPL to conduct experiments for directly studying crucial reactions at stellar energies in the evolution of stars. In 2020, JUNA commissioned an mA level high current accelerator based on an ECR source, as well as high efficiency BGO and $^{3}$He detectors. These combination...

    Invited Talk

    The study of many reactions of astrophysical relevance can benefit greatly from direct cross section measurements in a deep underground environment, where the low cosmic-ray background of these sites can be exploited to achieve excellent sensitivity. In this talk I will give an overview of recent results from the LUNA collaboration with a focus on $^{14}$N(p,$\gamma$)$^{15}$O.

    Invited Talk

    The Jiangmen Underground Neutrino Observatory~(JUNO) is a 20-kiloton liquid scintillator (LS) detector under construction in south China. It is designed to precisely measure the oscillation of reactor antineutrinos from two commercial nuclear power plants 53km away, with the goal of determining the neutrino mass ordering and measuring three oscillation parameters to sub-percent precisions. ...

    Invited Talk

    The goal of nuclear astrophysics is to measure cross sections of nuclear physics reactions of interest in astrophysics and to evaluate reaction rates for improvement knowledge of stellar evolution and synthesis of elements. At typical temperatures of stellar cores, the energy region of interest, the so-called Gamow window, is of the order of hundred keV and cross sections are very low due to...

    Underground Nuclear Astrophysics
    Invited Talk

    The origin of calcium production in the first stars (Pop III stars), which formed out of the primordial matter of the Big Bang, and their fates, remain most fascinating mysteries in astrophysics. Advanced nuclear burning and supernovae were thought to be the dominant source of the Ca production seen in all stars. Here we report on a qualitatively different path to Ca production through...

    Oral Talk

    Dark matter and neutrinos are essential ingredients in the evolution of the Universe. The PandaX collaboration has built a series of xenon-based time projection chambers (XeTPC) to search for dark matter particles, neutrinoless double beta decay, and astrophysical neutrino signals. PandaX-4T is currently running, and we released the second dataset in summer 2024. This talk highlights recent...
