Warped Starlight Could Be The Signpost That Points to Dark Matter in The Milky Way

When we peer out into intergalactic space, evidence for dark matter is everywhere. It’s in the rotation of galaxies, which cannot be accounted for by observable matter alone. It’s in the way galaxies cluster together, and the path of light as it travels through the Universe. We can’t see dark matter directly, but the effects it has on other objects has allowed us to map it pretty comprehensively on large scales.

It was done some 20 or so years back for stars in the Large Magellanic Cloud. In order to detect dark matter in the Milk Way’s halo. IIRC, only two eclipses and one lensing event were detected. Far too few to account for a significant fraction of dark matter.

But feel free to search. You may spot something unexpected.

What if computers did the checking for gravitational lensing of each star in the milky way ?

or would it better if certain stars were only looked at ?
