The largest-ever survey of physicists from around the world—released today—shows a distinct lack of consensus across many of physics's most important questions, from the nature of black holes and dark matter, to the still-incomplete ...
Cornell astronomers are deploying a new instrument that grants them, for the first time, a better view of the universe's earliest galaxies, which can't be observed individually with traditional ground- or space-based telescopes.
Supermassive black holes lurk at the centers of massive galaxies, including our own Milky Way. Puzzlingly, supermassive black holes more than a billion times the mass of the sun appear to exist just a few hundred million ...
An international team led by researchers at the Institute of Cosmos Sciences of the University of Barcelona (ICCUB) has developed a new method that could significantly improve our understanding of the expansion of the universe ...
Understanding the universe as a whole requires simulations on cosmic scales. An international team of astrophysicists, with a leading role for researchers at Leiden University, Netherlands, has now released one of the largest ...
Ultra-faint dwarf galaxies—tiny satellite galaxies orbiting the Milky Way—have long been seen as cosmic fossils. Now, a new study published today in Monthly Notices of the Royal Astronomical Society uses an unprecedented ...
The cosmological constant is the mathematical description of the energy that drives the ever-accelerating expansion of the cosmos. It's also the source of one of the most enduring and confounding problems in modern physics.
The Dark Energy Spectroscopic Instrument (DESI) has successfully completed the largest high-resolution 3D map of the universe ever made, a major milestone in understanding the force driving cosmic expansion. The milestone ...
In the era of precision cosmology, research often means big science: large observatories, highly complex instruments, international collaborations and substantial funding. Yet even in such an advanced field, progress is still ...
Gravity, as most people understand it, is the familiar force that pulls a falling apple toward Earth. But for astronomers and theoretical physicists, it is also a vexing invisible architect that guides the shape and evolution ...
