New Telescopes to Study the Aftermath of the Big Bang
The NSF just awarded researchers at UChicago to start developing the CMB-S4 experiment, which will map the earliest moments of…
A Black Hole Switched On in the Blink of an Eye
A new study describes how astronomers discovered a supermassive black hole that suddenly "switched on" and became
Gravitational Waves Can Be Gravitationally Lensed, and This Could Provide Another Way to Measure the Expansion of the Universe
Astronomers can never have enough ways to measure the expansion in the Universe, from nearby stars to distant quasars. A…
Next Generation Gravitational Wave Detectors Could Pin Down Dark Matter
Gravitational astronomy is a relatively new discipline that has opened many doors for astronomers to understand how the huge and…
Early Black Holes Were Bigger Than We Thought
Every large galaxy in the nearby universe contains a supermassive black hole at its core. The mass of those black…
Astronomers Have Never Detected Merging Supermassive Black Holes. That Might Be About to Change
A new study suggests that pulsars could act as natural gravitational wave sensors, setting limits on supermassive black hole mergers…
We Might Soon Detect the Gravitational Waves from Dying Stars
Researchers have discovered an exciting new source of gravitational waves. They are the remnants left over from a supernova explosion,…
When Black Holes Merge, They'll Ring Like a Bell
How a merged black hole rings as it settles into a stable form holds clues to a better understanding of…
LISA Will Be a Remarkable Gravitational-Wave Observatory. But There’s a Way to Make it 100 Times More Powerful
A team of researchers with the ESA propose an upgrade for the LISA mission (LISAMax), which could revolutionize gravitational wave…
Gravitational Waves From Colliding Neutron Stars Matched to a Fast Radio Burst
A recent study by an Australian-American team has provided compelling evidence that FRBs may be caused by merging neutron stars.
