The rest of the universe appears to be made of a mysterious, invisible substance called dark matter (25 percent) and a force that repels gravity known as dark energy (70 percent). Scientists have ...

The first dark matter search using the WINERED spectrograph on a large telescope in Chile has set new constraints on the lifetime of dark matter particles with masses between 1.8 and 2.7 eV.

"Most of them are solitary. In this new work, we show how to effectively double the number of pulsars we can use to constrain dark matter in the galaxy by rigorously using solitary pulsars to ...
