Proton acceleration in thermonuclear nova explosions revealed by gamma rays
Classical novae are cataclysmic binary star systems in which the matter of a companion star is accreted on a white dwarf. Accumulation of hydrogen in a layer...
RAFFAELLA MORGANTI: "The first image of a black hole was an important milestone for astrophysics"
Radioastronomy is one of the branches of observational astrophysics which has experienced considerable growth in recent years. To study the universe at radio...
Rapid quasi-periodic oscillations in a relativistic jet
Active galactic nuclei (AGN) consist of a supermassive black hole fed by the circumnuclear material close to the galaxy center. Around 10% of the AGNs develop a...

Relativistic jets blowing bubbles in the central region of the Teacup Galaxy
When matter falls into supermassive black holes in the centres of galaxies, it unleashes enormous amounts of energy and is called active galactic nuclei (or AGN...
Researchers from the IAC have discovered that dark matter experiences forces beyond gravity
The existence of dark matter is likely one of the most perplexing problems facing the scientific community, and unraveling its nature has become one of the...
