Whilst looking for axion-mass DM candidates, the XENON1T experiment has indeed seen a surplus of events; but this does not necessarily mean the detection of a DM particle.

Protoplanetary discs- discs of gas and dust around young stars, in which planets are forming- could be used to probe for very-low-mass axion DM candidate particles.

Correlation between the distributions of the diffuse gamma-ray glow across the sky and matter throughout the universe may help throw light on the search for gamma-ray emission from dark matter particle annihilation.

Observations by the Hubble Space Telescope of gravitationally-lensed quasars have been used to detect the smallest clumps of dark matter found thus far.
