The fate of the Universe depends on the balance between matter and dark energy, the fundamental ingredient that drives its accelerating expansion.

Physical Review Letters magazine has published a paper by Nicolás Sanchis Gual (UV), Juan Calderón Bustillo (IGFAE), and Adrián del Río (UC3M-UV) which analyses the possible asymmetry of black hole fusions. A paper led by researchers from the Universitat de València (UV), the Galician Institute of High Energy Physics (IGFAE), and Charles III University of Madrid (UC3M) researches the possible existence of asymmetries in the universe through the analysis of the direction of rotation in black hole fusions.

Traditional black holes, as predicted by Albert Einstein's theory of General Relativity, contain what are known as singularities , i.e. points where the laws of physics break down. Identifying how singularities are resolved in the context of quantum gravity is one of the fundamental problems in theoretical physics.

Researchers from the Institute of Corpuscular Physics (IFIC, UV-CSIC) achieve to measure at the laboratory the formation of a key element in the evolution of chemical make-up of the heavy elements. An isotope of this element, Lead-204, is produced in giant red stars, responsible for the creation of half of the elements which are heavier than iron in nature.

These images allow scientists to search for wandering planets, study dark matter using lensed galaxies and explore the evolution of the universe.

An international scientific team, led by the Center for Astrobiology (CAB), CSIC-INTA and including Cristina Cabello, postdoctoral researcher at the Institute of Particle Physics and Cosmos of the Complutense University of Madrid (IPARCOS-UCM), has discovered the most distant Milky Way-like barred galaxy known to date.

University of Valencia researchers propose a theoretical model that explains the interior of a blazar, the most powerful source of radiation in the Universe José María Martí and Manel Perucho, researchers at the University of Valencia, are the authors of the theoretical model that has made it possible to interpret the image with the highest resolution and sensitivity ever achieved of a blazar, the jet of matter that emerges from the nucleus of a galaxy, in this case 3C 279, at a speed close to that of light.

Astronomers from the Universitat de València captured the detailed image of the first radiation belt detected around a brown dwarf outside our solar system. The image, taken last January and now published in the Science journal, evokes the well-known belts of Earth and Jupiter, reveals a magnetic field ten times greater than that of the largest planet in the solar system, and unlocks new secrets of these ultracool substellar objects of very low mass and very powerful radiation.

Researchers from the Universidad Carlos III de Madrid (UC3M), Polytechnic University of Milan and the company GMV have developed a new methodology for detecting and estimating satellite manoeuvres that improves the operation of the systems currently in use. This development, which is already being tested in operational environments, may help reduce the problem of space debris.

Recerca Space travel has always tested the human body by the effects of the new conditions of altered gravity on biological systems. It has long been known that continuous exposure to microgravity conditions human physiology and causes effects that compromise muscular, sensory, endocrine and cardiovascular functions.

An international research team led by the University of Valencia manages to automatically identify the most relevant changes that have occurred on planet Earth in the last 10 years and determine whether their causes are natural or anthropogenic. The results of the work, published in National Science Review, are obtained by combining a new statistical method with data from ESA-s SMOS satellite, which regularly provides global maps of soil and vegetation water content.

An international research team with the participation of the University of Valencia has just discovered a population of 6 massive and red galaxies, candidates to form part of the early universe. They are galaxies even older and more massive than most previously identified at those distances. The observations, made using NASA's JWST telescope, confirm the effectiveness of this space observatory and augur new insights into the beginnings of galaxy formation.

LIFU's advantage comes from the large amount of information contained in each observation. Using small displacements of the pointer, the WEAVE spectrograph has produced, in two hours, spectra for 31,500 regions in and around these galaxies. The total light intensity of each of the fibres is used to form the image of the galaxies shown in the centre.

An international research team led by the University of Valencia has just measured a time delay of 6.73 years -the longest ever detected for a gravitational lens- between multiple images of a quasar. The result, obtained after 14.5 years of observation at the FLWO observatory of the Harvard-Smithsonian Center for Astrophysics (USA), will improve knowledge about galaxy clusters and the dark matter they contain.

An international team, with the participation of the Universitat de València, has identified the signal of a bubble of hot gas orbiting in the vicinity of Sagittarius A* (the supermassive black hole at the centre of our galaxy). The observation was made with the ALMA telescope (Atacama large mm/submm Array).

A team from the Institute of Corpuscular Physics (IFIC, UV/CSIC) predicts that supernovae can be a source for determining the mass of neutrinos. This is explained by a theoretical study published in the journal Physical Review Letters. The experimental confirmation of the proposal is carried out within the framework of the international collaboration DUNE (Deep Underground Neutrino Experiment), whose future detector will observe, for this work, neutrinos from supernova explosions.

A team of international experts, renowned for having debunked several black hole discoveries, identified a stellar-mass black hole in the Large Magellanic Cloud, a galaxy near the Milky Way. The discovery is now published in an article on Nature Astronomy , which includes the participation of Mark Gieles, from the Faculty of Physics, the Institute of Cosmos Sciences of the UB (ICCUB) and the Institute of Space Studies of Catalonia (IEEC).

An international collaboration, involving the Stellar Astrophysics group of the Complutense University, has discovered two new super-Earths orbiting a bright red dwarf star located only 33 light-years away, making them the closest rocky planets ever found outside our solar system. Neither of the two worlds can harbor life.

A study by the Institute of Corpuscular Physics (CSIC-UV) and Harvard University shows for the first time the production of a type of neutrinos originating from extreme phenomena. The work, featured in the journal Physical Review Letters, represents a change for the models on which future Physics experiments looking for these elementary particles are based.
