Decoding the Cosmic Remnants of Black Hole Feasts

An international team of astronomers has discovered a new way to study the behavior of active black holes when they consume matter. The team found that active black holes in the center of galaxies emit microwave and X-ray light in a similar manner, regardless of their appetite for surrounding galactic matter. This finding challenges the current understanding of how black holes eat and suggests that these black holes may have more similarities than previously thought. The study could provide new insights into how galaxies evolve and offers a new method for estimating black hole masses.

"Groundbreaking Prediction Unveils Exciting New Property of Hydrogen"

Physicists from Kiel and Dresden have predicted a new property of hydrogen, revealing that under high pressure, hydrogen exhibits an unusual "roton-like behavior" similar to exotic Bose fluids. This behavior is observed when hydrogen is irradiated with X-ray light, causing electrons to come unusually close to each other and even form pairs, despite their repulsion. Computer simulations have provided exact predictions for observing this behavior, and now experimental physicists will work to confirm it.

Uncovering the Mysteries of the Milky Way's Supermassive Black Hole Flare.

NASA's IXPE spacecraft detected an eerie sound coming from the supermassive black hole, Sagittarius A*, at the center of the Milky Way. Scientists believe the sound is an echo of a violent outburst that occurred over 200 years ago when a mass of gas and dust got too close to the black hole, causing it to wake up from a state of dormancy and devour the materials. The X-ray light emitted during the outburst bounced and echoed, which was turned into sound waves. The discovery was made by astronomers at France's Astronomical Strasbourg Observatory.
