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...
Recommendations to Keep Dark and Quiet Skies for Science and Society. Summary
This report analyses all types of artificial interference that may have a negative impact on the visibility of the night sky and astronomical science. The...
The “Lambda Cold Dark Matter” (CDM) cosmological model is the current theory credited for reproducing the physics responsible for the formation and evolution of...
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 have observed the heating produced in the Sun by magnetic waves
An international team in which researchers from the Instituto de Astrofísica de Canarias (IAC) and the Universidad de La Laguna (ULL) are participating...
Researchers show that the shape of the Whirlpool galaxy has been molded by the repeated passage through its disc of a satellite galaxy
An international research team, with participation by the Instituto de Astrofísica de Canarias (IAC) shows that the satellite galaxy NGC 5195 has passed twice...
Rocky exoplanets and their host stars may have similar composition
Newly formed stars have protoplanetary discs around them. A fraction of the material in the disc condenses into planet-forming chunks, and the rest finally...
Rotation found in three galaxies satellites of the Milky Way
An international team of astrophysicists from the Instituto de Astrofísica de Canarias (IAC), the University of La Laguna (ULL) and the Space Telescope Science...
Rough, dense with boulders and low albedo surface of Bennu revealed through images of NASA OSIRIS-REx mission
The first results on the analysis of the images of Bennu obtained using OCAMS, OVIRS, and OTES instruments on-board NASA’s OSIRIS-REx spacecraft have been...
