An article that will be published in the journal “Monthly Notices of the Royal Astronomical Society” describes a research on the origin of supermassive black holes. A team of Italian scientists led by Fabio Pacucci of Scuola Normale Superiore of Pisa used NASA’s space telescopes to identify two ancient objects that represent the best candidates black hole “seeds” found so far.
An article published in the journal “Astrophysical Journal Letters” describes the most precise measurement so far carried out of the mass of a supermassive black hole. A team led by astronomer Aaron Barth of the University of California, Irvine (UCI) used the ALMA radio telescope to examine the supermassive black hole at the center of the galaxy NGC 1332.
An article published in the journal “Nature” describes the discovery of one of the biggles black holes found so far. Using data collected from the Hubble Space Telescope and the Gemini North telescope in Hawaii, an international team of astronomers discovered a supermassive black hole with a mass estimated at around 17 billion times the Sun in the galaxy NGC 1600. It’s an extraordinary mass considering that it’s inside a galaxy very large but fairly isolated.
An article published in the journal “Monthly Notices of the Royal Astronomical Society” describes a research on the distribution of matter in the universe. According to the results 20% of ordinary matter is contained in the so-called cosmic voids and galaxies are only 1/500th of the volume of the universe. A team led by Dr Markus Haider of the Institute of Astro and Particle Physics at the University of Innsbruck in Austria, has used simulations of the Illustris project to reach these conclusions.
In Washington, D.C. a press conference was held to announce that the LIGO experiment found the gravitational waves predicted by Albert Einstein’s theory of general relativity. Two blacks holes about 1.3 billion light years from Earth merged as a result of a collision emitting those waves.
LIGO (Laser Interferometer Gravitational-Wave Observatory) is an instrument designed specifically to detect gravitational waves. It was created in a collaboration between Caltech (California Institute of Technology) and MIT (Massachusetts Institute of Technology) with funding from the American NFS (National Science Foundation).
