Dark energy remains among the greatest puzzles in our understanding of the cosmos. In the standard model of cosmology called the Lambda-CDM, it is accounted for by adding a cosmological constant term in Einstein’s field equation first introduced by Einstein himself. This constant is very small and positive and lacks a complete theoretical understanding of why it has such a tiny value. Moreover, dark energy has some peculiar features, such as negative pressure and does not dilute with cosmic expansion, which makes at least some of us uncomfortable.

Many celestial bodies in the Universe are rotating, It is thus of great astrophysical interest to find exact metrics describing rotating, axially symmetric, isolated bodies. In the literature, many methods have been developed (see for example [

A discrepancy between mathematics and physics has plagued astrophysicists’ understanding of how supermassive black holes merge, but dark matter may have the answer.

The dense peaks in the wavelength distribution graph observed in a Lyman-Alpha forest indeed resemble many small trees. Each of those peaks represents a sudden drop in “light” at a specific and narrow wavelength, effectively mapping the matter that light has encountered on its journey to us.

Have you ever wondered what the universe looked like after the Big Bang when it was still in its infancy, a mere billion years old? With NASA’s new Nancy Grace Roman Space Telescope, we’re about to get a glimpse of the cosmic dawn.

This cosmic time machine is set to explore an era known as the cosmic dawn, a significant transition when the universe went from a foggy opacity to the stunning, star-filled expanse we observe today.

Behind this ambitious project is the esteemed astrophysicist Michelle Thaller from NASA’s Goddard Space Flight Center in Greenbelt, Maryland.

A team of astrophysicists led by Caltech has managed for the first time to simulate the journey of primordial gas dating from the early universe to the stage at which it becomes swept up in a disk of material fueling a single supermassive black hole. The new computer simulation upends ideas about such disks that astronomers have held since the 1970s and paves the way for new discoveries about how black holes and galaxies grow and evolve.

“Our new simulation marks the culmination of several years of work from two large collaborations started here at Caltech,” says Phil Hopkins, the Ira S. Bowen Professor of Theoretical Astrophysics.

The first collaboration, nicknamed has focused on the larger scales in the universe, studying questions such as how galaxies form and what happens when galaxies collide. The other, dubbed STARFORGE, was designed to examine much smaller scales, including how stars form in individual clouds of gas.

Astronomers have uncovered the secrets behind an epic collision of two massive galaxy clusters, showing that dark matter and regular matter can actually separate during these huge events.

Located billions of light-years away, these clusters are home to thousands of galaxies and provide deep insights into the complexities of our universe.
