Astronomers have discovered a huge reservoir of cold molecular gas, the direct fuel for star formation, in REBELS-25, a massive, star-forming galaxy. The team, led from Leiden University, focused on REBELS-25, seen when the universe was only about 700 million years...
GaN-based vertical-cavity surface-emitting lasers (VCSELs) are promising for displays, sensing and optical communication, but improving efficiency remains challenging. Researchers have now shown that “cavity tuning,” which controls resonance wavelength,...
We may not know what dark matter is, but we keep getting whiffs of it. “We are reaching a point where the observational evidence for dark matter is simply undeniable,” said Mayank Sharma, a Virginia Tech graduate student in physics. Go to...
In a quest to build the most accurate quantum sensors in the world, scientists are constantly improving their performance, making them more precise, more stable and more reliable. But eventually, physical constraints will prevent further improvements. Go to...
