GW250114: testing Hawking's area law and the Kerr nature of black holes
The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1785
The gravitational-wave signal GW250114 was observed by the two LIGO detectors with a network matched-filter signal-to-noise ratio of 80. The signal was emitted by the coalescence o…
Digitization of Weather Records of Seungjeongwon Ilgi: A Historical Weather Dynamics Dataset of the Korean Peninsula in 1623-1910
Zeyu Lyu, Kohei Ichikawa, Yongchao Cheng +2
Historical weather records from Europe indicate that the Earth experienced substantial climate variability, which caused, for instance, the Little Ice Age and the global crisis in…
Relationship of peak fluxes of solar radio bursts and X-ray class of solar flares: Application to early great solar flares
Keitarou Matsumoto, Satoshi Masuda, Masumi Shimojo +1
Large solar flares occasionally trigger significant space-weather disturbances that affect the technological infrastructures of modern civilization, and therefore require further i…
A Review for Japanese auroral records on the three extreme space weather events around the International Geophysical Year (1957 -- 1958)
Hisashi Hayakawa, Yusuke Ebihara, Hidetoshi Hata
Solar Cycle 19 was probably the greatest solar cycle over the last four centuries and significantly disrupted the solar-terrestrial environments with a number of solar eruptions an…
Records of sunspot and aurora activity during 581-959 CE in Chinese official histories in the periods of Suí, Táng, and the Five Dynasties and Ten Kingdoms
Harufumi Tamazawa, Akito Davis Kawamura, Hisashi Hayakawa +3
Recent studies of radioisotopes in tree rings or ice cores suggest that extreme space weather events occurred in the pre-telescope age. Observational records of naked-eye sunspots…
