High-Energy Astrophysics studies astronomical objects that release electromagnetic radiation at highly energetic wavelengths that is X-rays and gamma-rays. These wavelengths come from matter with very high temperatures revealing a hot and energetic Universe! AHEAD2020 (Activities in the High Energy Astrophysics Read More …
The covid-19 situation suspended all the visits on site, though the visits in EGO and Virgo will be LIVE BROADCASTED from the time beeing! Stay tuned! Galileo’s telescope opened the door to the stars, EGO and Virgo opened a new Read More …
The first massive galaxy groups in the Universe are predicted to have formed when the Universe was less than 4 billions years old (redshift > 2). Baryonic physics, like stellar and active galactic nuclei (AGN) feedback in this very active Read More …
For a long time astronomers have puzzled over the lack of observations of compact objects with masses ranging from 2.5 up to 5 solar masses. This mysterious grey area is known as the ‘mass gap’: a range of masses apparently Read More …
As most people stayed at home due to the coronavirus pandemic, we have prepared some educational presentations for children with ages below 14 to dive in-depth into astronomy topics. These series of presentations include videos, interactive games and a lot Read More …
In #AthenaNuggets 40, Jorge Sanz talks about the relationship between the emission of X-rays by a star and its exoplanets. The role of the X-rays is fundamental to understand the phenomena of erosion in exoplanet’s atmospheres. The sensitivity of Athena Read More …
#AthenaNuggets 42 proposes the study of quasars as new cosmic tracers. These astronomical objects will allow the measurement of the expansion rate of the Universe up to z~10, i.e., when the Universe was less than 500 million years old. The role Read More …
Ultraluminous X-ray sources (ULXs), the most extreme among binary stars, can aid us to face the following question: how many black holes managed to grow up to 10 billion Solar masses in less than a billion years after the Big Read More …
