Tenured professor of Physics at the University of Valencia (Spain). His research focuses on the study of relativistic fluids in different astrophysical scenarios using relativistic hydrodynamics and magnetohydrodynamics numerical simulations. Among the scenarios he studies, are the jets generated in active galactic nuclei or in binary X-ray or gamma-ray stars. He was the principal investigator on different supercomputer calculation projects as well as on an international observation project with the Russian space telescope Radioastron.
The Swedish Academy has awarded Roger Penrose, Reinhard Genzel, and Andrea Ghez the Nobel Prize in Physics. What is behind this shared award? When did the debate on black holes start? An analysis by Manel Perucho.
We see the sky and admire its regularity and stability, its apparent immutability. We have always done so; it does not come as a surprise, since humans have always been startled by any change in the sky, associating it with omens or the mood swings of gods. At that time, they might call these changes «new stars», even if they were, for example, a supernova explosion, as in the case of Tycho’s supernova in the sixteenth century.
