RAEGE-Az apresenta as primeiras observações do seu programa astrofísico com o Radiotelescópio de Santa Maria

A Associação RAEGE Açores – Rede Atlântica de Estações Geodinâmicas e Espaciais (RAEGE-Az) – apresentou hoje as primeiras observações do seu programa astrofísico utilizando o Radiotelescópio de Santa Maria. Incluindo imagens e espectros em radiofrequências de galáxias ativas, zonas de formação de estrelas, e remanescentes de supernova, as observações demonstram a capacidade do Radiotelescópio Colombo, …

C6.2 class flare parameters inferred with a 3D geometry of flare database

We analysed a GOES C6.2 class solar flare that occurred on 27 October 2003 at the heliographic position S20E29. Utilising a database developed from a simplified 3D magnetic loop model, we inferred a set of geometric and physical parameters to characterise the flare.This model, based on general properties of known solar flares and adjusted for …

Solar Radio Burst Monitoring Using GNSS Receivers in the Azores Archipelago

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 …

On The Selection And Exploration Of Radio Powerful Active Galactic Nuclei

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 …

Single-dish observations of methanol masers at 6.67 and 12.2 GHz with a 13.2 m VGOS radio telescope in the Mid-Atlantic

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 …

Assessing The Consistency Of The Conventional Reference Frames (Terrestrial And Celestial) And Their Impact On Estimated EOP Using VLBI-Based Data

The conventional International Terrestrial Reference Frame (ITRF) is based on the combination of solutions from several space geodetic techniques, including observations until the end of 2020, and incorporates updated data and models. In contrast, the Celestial Reference Frame (CRF) is a VLBI-only solution based on data until 2015. These differing approaches could potentially lead to …
