Using the Hubble Space Telescope 🔭, a team of astronomers have discovered a starless, gas-laden dark matter cloud believed to be a relic from the dawn of galaxy formation - the first verified discovery of its kind anywhere in the Universe ☁️. Check it out: https://ow.ly/e0WV50XT9Og #astronomy

It moves! We can watch as the Kepler supernova remnant changes over a quarter of century in X-rays from Chandra. #aas247

Congratulations to John Clarke, Michel H. Devoret and John M. Martinis! Very good news for quantum sensor based dark matter experiments :)
🎖️ The Nobel Prize in Physics is awarded to John Clarke, Michel H. Devoret and John M. Martinis!
The laureates used a series of experiments to demonstrate that the bizarre properties of the quantum world can be made concrete in a system big enough to be held in the hand.

With XENONnT we reached a very low radon level, equivalent to about 430 222-Rn atoms per tonne of xenon. For the first time, the radon induced background rate is similar to the event rate due to solar neutrinos (via neutrino-electron scattering): link.aps.org/doi/10.1103/...
Radon Removal in XENONnT down to the Solar Neutrino Level
Using advanced cryogenic distillation, the XENONnT experiment cuts radon levels in its 10-tonne liquid xenon detector to just 430 atoms per tonne, enabling ultrapure conditions for detecting faint dar...

Very nice result from a combined analysis of the data from the ANAIS and COSINE experiments: no annual modulation in their NaI(Tl) detectors is observed
New test of DAMA/LIBRA result available: No modulation observed by ANAIS and COSINE collaborations.
Our combined results, published in Physical Review Letters, have been highlighted as editor's suggestion and featured in the Physics Magazine:

True then, and now “Dr. Gaillard’s appointment showed that physicists did not have to be arrogant or aggressive to succeed, said Marjorie Shapiro, who was then a physics graduate student at Berkeley and who in 2004 became the first woman to chair the physics department at Berkeley.”
