IN BRIEF Mass: between 0.3 and 1.4 times that of the Sun Volume: similar to that of the Earth Density: very high, resulting in intense gravitational forces Mass-size relation: the greater the mass, the smaller the size Electrons: exert a dominant quantum pressure within these celestial bodies Compactness: makes these celestial bodies sensitive to gravitational … Read more
IN BRIEF Supercomputers: essential tools for research in astrophysics. Used for complex simulations of cosmic phenomena. Collaboration of researchers through supercomputers like Frontera and Jean Zay. Computational capacities exceeding quadrillions of operations per second. Ongoing projects to create the largest 3D map of the universe. Impact on the understanding of the evolution of the universe … Read more
IN BRIEF Gravitational singularity: a region of spacetime where the laws of physics become imprecise. Involves mathematical limits according to the Einstein theory. References to the Penrose theorems and Hawking regarding black holes. Singularities are points where certain physical parameters reach infinity. The hidden singularity implies that physical laws break down. Interest in cosmology to … Read more
IN BRIEF Definition: Celestial objects in an intense gravitational field. Formation: Collapse of a massive star at the end of its life. Singularity: Central point where mass is concentrated. Dark matter and dark energy: Mysteries related to their presence around black holes. General relativity: Theoretical framework to study the properties of black holes. X-ray telescopes: … Read more
IN BRIEF Detection of dark matter: innovative approach based on Josephson junctions. Exploration of gravitational waves to identify dark matter. Search for axions, potential candidates for dark matter, via their conversion into photons. Clear strategies: to do, see oneself undone, or look for its shakes. Study of neutron stars, potential keys in the detection of … Read more
IN BRIEF Definition: Celestial objects with intense gravitational fields. Composition: Very compact, high mass/size ratio. Role: Impact on the growth of galaxies. Event horizon: Limit beyond which nothing can escape. Time travel: The gravity of a black hole allows for time dilation. Environment: Influence on galactic structures and their dynamics. Scientific research: Studies conducted to … Read more
IN BRIEF Star formation: Formation from the gravitational contraction of a nebula. Protostars: Clouds of gas that continue to contract to develop a star. Composition: Balls of gas mainly composed of hydrogen and helium. Process: Gravitational collapse of interstellar clouds. Stellar evolution: Life cycle encompassing the birth, evolution, and death of stars. Ongoing formation: About … Read more
