"However, not all scientists are convinced by the new results. Several groups have previously ruled out GCE contributions by dark matter particles that are less massive than 400 gigaelectron volts. Other skeptics argue that the excess light is from undiscovered stars, as the light distribution maps closely to where stellar populations should be."
Some words of caution near the end of the article. Here are some other reports on DM in the center of the Milky Way. Study rules out dark matter destruction as origin of extra radiation in galaxy center,

Astrophysicist probes cosmic 'dark matter detector',
https://phys.org/news/2020-09-astrophysicist-probes-cosmic-dark-detector.html, September 2020. "In two recent studies, Jeremy Darling, a professor in the Department of Astrophysical and Planetary Sciences, has taken a deep look at PSR J1745-2900. This body is a magnetar, or a type of collapsed star that generates an incredibly strong magnetic field. "It's the best natural dark matter detector we know about," said Darling, also of the Center for Astrophysics and Space Astronomy (CASA) at CU Boulder..."
There are many published reports looking for DM using various DM theoretical particles. Many reports show null results. Where is the website tracking all of these reports for the public? Example, the exoplanet sites now posted like
http://exoplanet.eu/ or
https://exoplanetarchive.ipac.caltech.edu/index.html
I think more transparency is needed here concerning DM reporting and a full disclosure similar to the exoplanet reporting model now in use.
