Solar radio bursts are characterised by intense electromagnetic radiation emitted from the Sun’s atmosphere releasing huge amounts of energy in the order of ∼ 10 32 ergs and are crucial indicators of solar activity. These burst events might drive extreme space weather phenomena such as geomagnetic storms, ionospheric disturbances, and communications disruptions. Real-time prediction of …

One of the fundamental questions in astronomy is how galaxies form and evolve through cosmic time. For the past few decades, various teams have been trying to answer this question through the construction of computational models for simulated galaxies and their associated active galactic nuclei (AGN). With the next generation of telescopes currently developing survey …

The RAEGE network (Portuguese/Spanish acronym for Atlantic Network of Geodynamic and Space Stations) is a cooperation project between the National Geographic Institute of Spain and the Regional Government of the Azores. The project will build and operate four geodetic stations: two in the Azores archipelago, in Portugal (Santa Maria and Flores islands), and two in …

The Global Geodetic Observing System (GGOS) of the International Association of Geodesy (IAG) envisages stringent goals for the International Terrestrial Reference Frame (ITRF) realization in terms of accuracy (1 mm) and precision (0.1 mm/year). These requirements entail that the Earth Orientation Parameters (EOP) should be estimated with similar accuracy. The conventional International Terrestrial Reference Frame …
