A team led by Tokyo Metropolitan University has made significant strides in the search for dark matter. Using advanced spectrographic technology and the Magellan Clay Telescope, they observed galaxies. With just four hours of observations in the infrared range, they set new limits on the lifetime of dark matter. Their findings demonstrate the power of their technology and expand the search to less explored parts of the spectrum.
For decades, cosmologists have noticed that galaxies rotate in a way that suggests there is more mass than we can see, dubbed “dark matter.” This elusive substance is challenging to study because it is invisible and has unclear properties.
