How to observe a ‘black hole symphony’ using gravitational wave astronomy

NOVEMBER 18, 2019 by Vanderbilt University Shrouded in mystery since their discovery, the phenomenon of black holes continues to be one of the most mind-boggling enigmas in our universe. In recent years, many researchers have made strides in understanding black holes using observational astronomy and an emerging field known as gravitational wave astronomy, first hypothesized by Albert […]

Could the mysteries of antimatter and dark matter be linked?

The BASE group collaborators wondered whether the lack of antimatter might be because it interacts differently with dark matter, and set out to test this.  NOVEMBER 13, 2019 by RIKEN Could the profound mysteries of antimatter and dark matter be linked? Thinking that they might be, scientists from the international BASE collaboration, led by Stefan Ulmer […]

New research on giant radio galaxies defies conventional wisdom

Conventional wisdom tells us that large objects appear smaller as they get farther from us, but this fundamental law of classical physics is reversed when we observe the distant universe. OCTOBER 25, 2019 by Michelle Ulyatt, University of Kent Astrophysicists at the University of Kent simulated the development of the biggest objects in the universe to […]

Gravity crystals: A new method for exploring the physics of white dwarf stars

OCTOBER 21, 2019 by American Physical Society Grab a mixing bowl from your kitchen, throw in a handful of aluminum balls, apply some high voltage, and watch an elegant dance unfold where particles re-arrange themselves into a distinct “crystal” pattern. This curious behavior belongs to the phenomenon known as Wigner crystallization, where particles with the same […]

Stormy cluster weather could unleash black hole power and explain lack of cosmic cooling

This so-called “cooling flow” puzzle has plagued astrophysicists for more than 25 years. OCTOBER 17, 2019 by Dr Robert Massey, Royal Astronomical Society “Weather” in clusters of galaxies may explain a longstanding puzzle, according to a team of researchers at the University of Cambridge. The scientists used sophisticated simulations to show how powerful jets from supermassive […]

Astronomers use giant galaxy cluster as X-ray magnifying lens

New lens technique spots tiny dwarf galaxy in the first, super-energetic stages of star formation. Jennifer Chu | MIT News OfficeOctober 14, 2019 Astronomers at MIT and elsewhere have used a massive cluster of galaxies as an X-ray magnifying glass to peer back in time, to nearly 9.4 billion years ago. In the process, they […]

For newborn planets, solar systems are naturally baby-proof

OCTOBER 10, 2019 by Max Planck Society Numerical simulations by a group of astronomers, led by Mario Flock from the Max Planck Institute for Astronomy, have shown that young planetary systems are naturally “baby-proof”: Physical mechanisms combine to keep young planets in the inner regions from taking a fatal plunge into the star. Similar processes also […]

First exoplanet found around a Sun-like star

October 8, 2019 Kepler Space Telescope’s 1st Exoplanet Candidate Finally Confirmed In 1995, astronomers detected a blisteringly hot Jupiter-mass planet orbiting closer to its host star than Mercury is to the Sun. This discovery recast our thinking of how planets form and led to a new era of exoplanetary exploration. Anyone over the age of […]
