In a groundbreaking discovery, scientists at Case Western Reserve University have uncovered new evidence that could fundamentally reshape our understanding of the universe. Tobias Mistele, a post-doctoral scholar in the Department of Astronomy at Case Western Reserve’s College of Arts and Sciences, has utilized a novel approach involving “gravitational lensing” to explore the elusive realm … Read more
Contrary to the prevailing assumptions of the standard model, recent research suggests that dark matter may indeed be self-interacting. This groundbreaking study, published in Astronomy & Astrophysics and led by Riccardo Valdarnini of SISSA’s Astrophysics and Cosmology group, used numerical simulations to explore the dynamics within “El Gordo” (Spanish for “The Fat One”), a colossal … Read more
Astronomers from India and South Africa have made significant strides in understanding the massive galaxy cluster known as Abell 2566 through data analysis from NASA’s Chandra X-ray Observatory. Their research, reported in a paper published on May 17 on the preprint server arXiv, reveals the presence of sloshing cold fronts within the intracluster medium (ICM) … Read more
Nearly every massive galaxy hosts a supermassive black hole at its center. When two galaxies merge, their black holes can form a binary pair, meaning they are in a bound orbit with one another. It’s hypothesized that these binaries are fated to eventually merge, but this has never been observed. The question of whether such … Read more
An extraordinary scientific endeavor led by astronomers at Ben-Gurion University of the Negev, spearheaded by Dr. Lukas Furtak and Prof. Adi Zitrin, has unveiled a remarkable discovery utilizing data from the James Webb Space Telescope (JWST). Their findings, published in Nature, shed light on an exceptionally red, gravitationally lensed supermassive black hole lurking in the … Read more
We now have a standard model of cosmology, the current version of the Big Bang theory. Although it has proved very successful, its consequences are staggering. We know only 5% of the content of the universe, which is normal matter. The remaining 95% is made up of two exotic entities that have never been produced … Read more
Astronomers have discovered one of the most powerful eruptions from a black hole ever recorded. This mega-explosion billions of years ago may help explain the formation of a striking pattern of star clusters around two massive galaxies, resembling beads on a string. This discovery was made in the system known as SDSS J1531+3414 (SDSS J1531 … Read more
