Its field of view of 1.77 deg 2 is the largest among current 8m-class telescopes, which makes the Subaru/HSC the most efficient instrument for the optical survey. We, Japanese Collaboration for Gravitational-Wave Electro-Magnetic Follow-up (J-GEM), had performed follow-up surveys for gravitational wave events using Subauru/HSC in the past LIGO-Virgo-KAGRA (LVK) observing runs. We summarize our follow-up surveys. In particular, the follow-up survey for an optical counterpart of a binary neutron star coalescence GW170817 covered 56% credible region and reaches the 50% completeness magnitude of 20.6 mag on average. We found 60 candidates of extragalactic transients and evaluated the probability that these candidates are located inside of the 3D skymap. As a result, we concluded that AT2017gfo is the most-likely and distinguished candidate as the optical counterpart of GW170817 and demonstrated the uniqueness of AT2017gfo. We also conducted the follow-up surveys for binary black hole coalescences, GW151226, S190510g, and GW200224_222234. Although we could not identify promising candidates of their optical counterparts, we put upper limits of optical luminosity of possible counterparts. We also introduce our strategy and the status of follow-up surveys using Subaru/HSC in the LVK O4 run.","PeriodicalId":448458,"journal":{"name":"Proceedings of 38th International Cosmic Ray Conference — PoS(ICRC2023)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115730697","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To address this issue, we are redeploying the Haleakala Neutron Monitor (HLEA) on the island of Maui. HLEA was established in 1991 but was subsequently decommissioned in 2006 due to funding constraints. Its strategic location at a high altitude on Haleakala mountain, situated in the middle of the Pacific Ocean, offers unique advantages for SNP detection. The reinstatement of HLEA represents an invaluable opportunity to extend ground coverage for SNP and GCR detection, enhance the global NM network, and contribute to a deeper understanding of high-energy particle interactions. By harnessing the potential of this revitalized NM station, we aim to enrich space weather research and improve the efficacy of space weather monitoring systems, thereby enhancing our preparedness and resilience against space weather hazards.","PeriodicalId":448458,"journal":{"name":"Proceedings of 38th International Cosmic Ray Conference — PoS(ICRC2023)","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126137220","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These results on cosmic-ray electrons in the energy range from 1 GeV to 2 TeV reveal new features that are crucial for providing insights into their origins. Comparing the behavior of the electron spectrum with the spectrum of positrons measured by AMS, we found that at lower energies below few hundred GeV these two spectra have distinctly different magnitudes and energy dependences. This shows that at lower energies these two species of cosmic ray particles have very different origins. At high energies we observe that the source of high energy positrons, which has either particle or astrophysical origin, also manifests itself in the electron spectrum. This is the first indication of the existence of identical charge symmetric source term both in the positron and in the electron spectra and, as a consequence, the existence of new physics.","PeriodicalId":448458,"journal":{"name":"Proceedings of 38th International Cosmic Ray Conference — PoS(ICRC2023)","volume":"2012 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129230275","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Its primary scientific goal is the search for light antinuclei in cosmic rays at kinetic energies below 0.25 GeV/ 𝑛 . This energy region is especially of interest for beyond-the-standard model dark matter searches and is still mostly uncharted. Searches for light antimatter nuclei with energies below 0.25 GeV/ 𝑛 are a novel approach to the search for dark matter because wide range of dark matter models proposes annihilation or decay into matter-antimatter pairs. GAPS will yield unprecedented sensitivity to low-energy antideuterons and will measure the low-energy antiproton spectrum with high statistics and precision. To reach the required sensitivity, the GAPS detector incorporates a new approach for antimatter detection, utilizing a tracker with custom, lithium-drifted silicon detectors, designed to measure the X-ray cascade expected from antimatter capture and charged particles from the subsequent annihilation. It also utilizes a fast time-of-flight system, allowing for a high-precision beta measurement. This proceeding highlights GAPS scientific goals.","PeriodicalId":448458,"journal":{"name":"Proceedings of 38th International Cosmic Ray Conference — PoS(ICRC2023)","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121799941","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The isotropic diffusion model requires a feasible way of generating strong turbulence in the ambient interstellar medium. The streaming instability driven by escaping electron/positron pairs is not sufficient, but it might work with certain pre-amplification of the turbulence. The anisotropic diffusion model predicts many pulsar halos with elongated morphology, which are currently not detected. We demonstrate that those elongated halos are difficult for detection, but long-term exposure of LHAASO may discover some of them, which may serve as a critical test of the model. Finally, we show that pulsar halos, with either model, may have important contribution to the diffuse Galactic gamma-ray emission (DGE).","PeriodicalId":448458,"journal":{"name":"Proceedings of 38th International Cosmic Ray Conference — PoS(ICRC2023)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133636090","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The wide use of FFA is motivated by the fact that the modulation strength can be described, with reasonable accuracy, using a single variable parameter 𝜙 , which is called the solar modulation potential. While FFA does not allow us to study the solar modulation process in detail, the one-parameter feature is useful, especially in the context of energy-and particle-integrating detectors, such as neutron monitors and cosmogenic isotopes, which allows for studies of solar modulation on timescales beyond the direct measurements. New daily data on proton and helium fluxes measured by cosmic-ray experiment AMS-02 for the period from 2011 to 2019 open new opportunities in the verification of the FFA of the solar modulation equation on a daily basis and in a systematic comparison of the solar modulation deduced from different detectors (including energy-integrating ones). In this work, we reconstruct the solar modulation potential from daily AMS-02 data, compare it to daily solar modulation potential values reconstructed from NM data, and discuss the proper way to evaluate the solar modulation potential from different detectors to make them comparable.","PeriodicalId":448458,"journal":{"name":"Proceedings of 38th International Cosmic Ray Conference — PoS(ICRC2023)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130070680","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
