Characterizing galaxies at “cosmic noon”
Astronomers studied 3 galaxies that formed 2 to 3 billion years after the Big Bang to calculate how much gas, stars, and dark matter they…

What lies between the stars?
Astronomers simulated the clouds of material between stars. They found that regions of space with more heavy elements tend to be cooler and…
The fate of massive rotating stars
Researchers showed that massive stars at the end of their lives are more likely to collapse into black holes than to explode into…
Astronomers model early star clusters
Scientists used computer simulations to determine how ancient star clusters formed. Their results were similar to real clusters found with…
Do black holes come in pairs?
Astronomers modeled how black holes merge and found that most converged black holes started as large stars in a binary system. They also…
How did supermassive black holes form?
An astronomer analyzed ancient supermassive black holes with mathematical models and found they likely grew exponentially after light,…
Why do galaxies shrink?
An astronomer studying the 3 main processes that cause galaxies to lose mass found that the dominant process depends on the size and age of…
Energetic winds from a distant X-ray source
A team of astronomers were studying GRS 1716-249, an object believed to host a black hole. A wind of gas flowing out of it can be seen in…
Two Black Holes Made a Mega Black Hole!
1.76 billion light years away, two black holes smashed into one another, bearing one huge black hole the size of 53 suns. The explosion from…
