Recent Results and Status of TA/TALE/TA $$\times$$ 4 Experiment

The Telescope Array (TA) experiment is a largest cosmic-ray observatory in the northern hemisphere, which aimed to study the origin of the ultrahigh energy cosmic rays (UHECRs). UHECRs with energies above $$10^{18}$$ eV are expected to remember where they came from, despite deflections by galactic and extragalactic magnetic fields. TA consists of two types of detectors, an atmospheric fluorescence telescope and a surface detector array, enabling hybrid observations of air shower phenomena. The detector is located in the western desert of Utah, USA, at an altitude of 1400 m. The TA Low-energy Extension (TALE) experiment is located in the north of the site, which consits of also the fluorescence telescope and dense array, to observe the cosmic rays with energies above $$10^{16}$$ eV. Furthermore, another extended experiment TA $$\times$$ 4 which aimed to quadruple the detection area of TA is started. TA $$\times$$ 4 started stable operation with fluorescence telescopes and the array of a half of planned area, and continue to expand the other half. We present the rescent results of TA/TALE/TA $$\times$$ 4 experiment, including energy spectrum, anisotropy and mass composition in this report.
