A starless dark matter halo finally found?
Artistic representation of the underlying gas distribution traced by the observed emission at the location of Cloud-9. Recent observations with the Five-hundred-meter Aperture Spherical Telescope (FAST) detected marginally-resolved extended gas emission near the M94 galaxy without an optical counterpart down to very faint limits (surface brightness ~29.15 mag/arcsec2 in the g band). In a recent work published in…
