TL;DR: The last decade has brought about a profound transformation in multimessenger science as discussed by the authors , with the discovery of the diffuse astrophysical neutrino flux, the first observation of gravitational waves by LIGO and the first joint detections in gravitational waves and photons and in neutrinos and photons.

TL;DR: In this article , the authors search for time clustering of the cosmic ray events collected with a small sea-level extensive air shower array at the University of Adelaide and find that the overall time distributions are as expected for random events.

TL;DR: In this paper, the authors used wavelet transforms to amplify distinctive image features and obtained a very good recognition ratio of almost 99% for both signal and artefacts. But the adverse effect of gamification is that the number of artefacts, i.e., signals unrelated to cosmic ray detection or openly related to cheating, substantially increases.

TL;DR: In this article, the fitness of several feature-based statistical classifiers for the classification of particle candidate hits in four categories: spots, tracks, worms and artefacts is analyzed.

TL;DR: In this article , the authors apply the method developed previously for identifying pairs of mutually remote extensive air showers, the ancestor particles of which arose, possibly, in a single process, to the data on the observation times and directions of the motion of extensive air shower, which are observed at two stations of the GELATICA network, for the first time.
