An international team of astronomers, led by SRON, has observed a sudden outburst of matter near the supermassive black hole NGC 3783 at speeds reaching up to 20% of the speed of light. During a 10-day observation, mainly ...
A new study by researchers at the University of Amsterdam shows how gravitational waves from black holes can be used to reveal the presence of dark matter and help determine its properties. The key is a new model, based on ...
In a study published in Physical Review Letters, physicists have demonstrated that black holes satisfy the third law of thermodynamics, which states that entropy remains positive and vanishes at extremely low temperatures, ...
An international research team led by PD Dr. Florian Peissker at the University of Cologne has used the new observation instrument ERIS (Enhanced Resolution Imager and Spectrograph) at the Very Large Telescope (VLT) facility ...
Astronomers from the University of Hawaiʻi Institute for Astronomy (IfA) have uncovered the turbulent past of a distant red giant by listening to its celestial "song." Subtle variations in the star's brightness suggest that ...
Primordial black holes (PBHs) are black holes theorized to have formed shortly after the Big Bang. Compared to black holes emerging from collapsing stars, PBHs could have very different masses, ranging from very small to ...
Tracking down black holes at the center of dwarf galaxies has proven difficult. In part it is because they have a tendency to "wander" and are not located at the galaxy's center. There are plenty of galaxies that might contain ...
Researchers using the NASA/ESA/CSA James Webb Space Telescope have confirmed an actively growing supermassive black hole within a galaxy just 570 million years after the Big Bang. Part of a class of small, very distant galaxies ...
An international collaboration of physicists including researchers at Washington University in St. Louis has made measurements to better understand how matter falls into black holes and how enormous amounts of energy and ...
Milestone results released by the Large High Altitude Air Shower Observatory (LHAASO) on November 16 have solved a decades-old mystery about the cosmic ray energy spectrum—which shows a sharp decrease in cosmic rays above ...
