Se ha medido el gradiente de abundancia de Oxígeno en la galaxia M33 con muestras relativamente grandes de regiones HII y usando dos métodos diferentes: primero...
Black Hole lightning due to Particle acceleration at Subhorizon Scales.
Supermassive black holes with masses of millions to billions of solar masses are commonly found in the centers of galaxies. Astronomers seek to image jet...
Black holes modulate star formation in neighboring galaxies
Every massive galaxy hosts a black hole in its center. Both the size and the mass of these black holes is negligible compared to the host galaxy, millions of...
Black-hole-regulated star formation in massive galaxies
The centres of massive galaxies are among the most exotic regions in the Universe. They harbour supermassive black holes, with masses of at least one million...

The centres of massive galaxies are among the most exotic regions in the Universe. They harbour supermassive black holes, with masses of at least one million...
Calibrating the Rossby number, a key parameter to study the magnetic activity of stars
In a star like the Sun, surface magnetic activity results from the interaction between rotation, convection, and magnetic field. One of the key parameters to...
Carbon and oxygen gradient values in recombination lines in HII regions
The galactic gradient of C has been determined for the first time using recombination lines in HII regions. Results from these lines are more reliable than...
CARMENES finds a nearby Neptune in the temperate zone of an early-M dwarf
We report on the first star discovered to host a planet detected by radial velocity (RV) observations obtained within the CARMENES survey for exoplanets around...
Characterization of the host galaxy from gamma-ray blazars
The most extreme electromagnetic radiation that can be observed is known as very high energy gamma rays (VHE, E>100 GeV). It is the last window open to the...
