Candidate detection of GRB221009A by Yangbajing muon telescope
Nozzoli, F.
Long gamma-ray bursts (GRBs) can be generated by the collapse of a rapidly rotating massive star into a black hole and are the brightest known explosive events in the Universe. GRB221009A is the most energetic gamma-ray burst ever recorded, providing delayed detection of very high energy photons that challenge the standard propagation mechanisms, …
Dual MeV gamma-ray and dark matter observatory - GRAMS Project
Odaka, Hirokazu; Aramaki, Tsuguo; Karagiorgi, Georgia +1 more
GRAMS (Gamma-Ray and AntiMatter Survey) is a novel project that can simultaneously target both astrophysical observations with MeV gamma rays and an indirect dark matter search with antimatter. The GRAMS instrument is designed with a cost-effective, large-scale LArTPC (Liquid Argon Time Projection Chamber) detector surrounded by plastic scintillat…
Measuring the Galactic Cosmic Ray flux with the LISA Pathfinder radiation monitor
Mendes, L.; Russano, G.; Lloro, I. +76 more
Test mass charging caused by cosmic rays will be a significant source of acceleration noise for space-based gravitational wave detectors like LISA. Operating between December 2015 and July 2017, the technology demonstration mission LISA Pathfinder included a bespoke monitor to help characterise the relationship between test mass charging and the l…
Borexino's search for low-energy neutrino and antineutrino signals correlated with gamma-ray bursts
Wang, H.; Meyer, M.; Smirnov, O. +98 more
A search for neutrino and antineutrino events correlated with 2350 gamma-ray bursts (GRBs) is performed with Borexino data collected between December 2007 and November 2015. No statistically significant excess over background is observed. We look for electron antineutrinos (νbare) that inverse beta decay on protons with energies from 1.…
A new limit on Planck scale Lorentz violation from γ-ray burst polarization
Stecker, Floyd W.
Constraints on possible Lorentz invariance violation (LIV) to first order in E/ MPlanck for photons in the framework of effective field theory (EFT) are discussed, taking cosmological factors into account. Then, using the reported detection of polarized soft γ-ray emission from the γ-ray burst GRB041219a that is indicative of an absence…
