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...
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...
Scientific results with the QUIJOTE-MFI wide survey: The anomalous microwave emission in our Galaxy and M31
In the 90s, the COBE satellite discovered that not all the microwave emission from our Galaxy behaved as expected. Part of this signal was later assigned to a...
Solving the enigma of the brightest planetary nebulae
Planetary nebulae (PNe) are the ejecta of evolved low-intermediate mass stars present in all stellar systems. Perhaps the easiest thing to do when studying PNe...
Solving the paradox of the enigmatic solar sodium D1 line polarization
In 1998 the journal Nature published a seminal letter concluding that the mysterious polarization (a particular property of light) that had been recently...
Temperature inhomogeneities cause the abundance discrepancy in H II regions
H II regions are ionized nebulae associated with the formation of massive stars. They exhibit a wealth of emission lines in their spectra that form the basis...
