Multi-instrument observations of ionospheric super plasma bubbles in the European longitude sector during the 23–24 April 2023 severe geomagnetic storm

open access: yesJournal of Space Weather and Space Climate
This study’s objective is to better specify the rare occurrence of super equatorial plasma bubbles in particular to the European longitude sector, detailing their spatio-temporal evolution, and better understanding pre-conditions for their development ...

Effects of a Cloth Panel Containing a Specific Ore Powder on Patients with Chamaecyparis obtusa (Cypress) Pollen Allergy

open access: yesThe Scientific World Journal, 2021
Pollen allergy to Japanese cedar and cypress is a serious illness that impairs daily life and sleep, especially during pollen season. We have reported that placing a cloth panel containing a specific natural ore powder (CCSNOP) in a room may alleviate ...

Galactic Center Observations with CTAO LST-1 [PDF]

open access: yesEPJ Web of Conferences
Very-high-energy gamma-ray observations of the central part of the Milky Way Galaxy allow for morphological study of cosmic-ray propagation around the supermassive black hole Sgr A*. An interpretation of the diffuse gamma-ray component, which spans a few

Templates for Fitting Photometry of Ultra-high-redshift Galaxies

open access: yesThe Astrophysical Journal Letters, 2023
Recent data from the James Webb Space Telescope allow a first glimpse of galaxies at z ≳ 11. The most successful tool for identifying ultra-high-redshift candidates and inferring their properties is photometric template fitting.

The Persistent Ionospheric Responses Over Japan After the Impact of the 2011 Tohoku Earthquake

open access: yesSpace Weather, 2020
In this study, we report the persistent impacts of the 2011 Tohoku earthquake/tsunami on the ionosphere using the ground‐based Global Navigation Satellite System and FORMOSAT‐3/COSMIC total electron content.

Is non-particle dark matter equation of state parameter evolving with time?

open access: yesEuropean Physical Journal C: Particles and Fields, 2021
Recently, the so-called Hubble Tension, i.e. the mismatch between the local and the cosmological measurements of the Hubble parameter, has been resolved when non-particle dark matter is considered which has a negative equation of state parameter ...

Case study on complex sporadic E layers observed by GPS radio occultations [PDF]

open access: yesAtmospheric Measurement Techniques, 2015
The occurrence of sporadic E (Es) layers has been a hot scientific topic for a long time. The GNSS (global navigation satellite system)-based radio occultation (RO) has proven to be a powerful technique for detecting the global Es layers.

GOLD plasma bubble observations comparison with geolocation of plasma irregularities by back propagation of the high-rate FORMOSA7/COSMIC 2 scintillation data

open access: yesFrontiers in Astronomy and Space Sciences
Using the high-rate phase and amplitude scintillation data from FORMOSA7/COSMIC two mission and back-propagation method, we geolocate plasma irregularities that cause scintillations.

Reducing representativeness and sampling errors in radio occultation–radiosonde comparisons [PDF]

open access: yesAtmospheric Measurement Techniques, 2018
Radio occultation (RO) and radiosonde (RS) comparisons provide a means of analyzing errors associated with both observational systems. Since RO and RS observations are not taken at the exact same time or location, temporal and spatial sampling errors ...
