Geochemistry, Geophysics, Geosystems, 2014 We undertake a petrologically driven approach to jointly model magnetotelluric (MT) and seismic surface wave dispersion (SW) data from central Tibet, constrained by topographic height. The approach derives realistic temperature and pressure distributions

Galactic Center Observations with CTAO LST-1 [PDF]
EPJ Web of ConferencesVery-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

COSMO-97, 1998 The current cosmological constraints on a dark matter axion are reviewed. We describe the basic mechanisms by which axions are created in the early universe, both in the standard thermal scenario in which axion strings form and in inflationary models. In the thermal scenario, the dominant process for axion production is through the radiative decay of ...

Space WeatherThe space weather event on 10–11 May 2024 was a high‐impact geomagnetic storm, resulting in a SYM‐H index decrease to −518 nT, the lowest level registered in several decades. We investigated the response of the Earth's ionosphere during the main phase of

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

Sun-to-Mud observations of the May and October storms of 2024: impacts on Ireland’s Space Weather
Journal of Space Weather and Space ClimateNear the peak of Solar Cycle 25 in 2024, Earth was impacted by two major solar eruptive events which triggered dramatic geomagnetic storm activity. In May 2024, multiple solar eruptive events generated the largest geomagnetic storm since the early 2000s;
