Could such dead matter account for any of the missing mass attributed to Dark Matter? Very vaguely, the dead matter distribution looks vaguely like a DM halo around the galaxy.
If they exist we would expect to detect them as they pass between another star and earth creating a gravitational lens. You can estimate the number of these MACHOs by looking at a bunch of stars for a long period of time and counting the number of microlensing events you see.
A team did this in 2000 and found that while there were some events, there weren't enough to explain all of the dark matter around the Milky Way. https://arxiv.org/abs/astro-ph/0001272
The "kicks" are just tranforming the galactic orbital path from the typical "visible star path" to a different set of paths. The objects still would pass through the visible layer at some point, so the lensing events would still occur.
You know, assuming the described calculated results are true.
Now consider that according to the paper 30% is going to leave the Galaxy. Those after the initial travel will never contribute to anything.
The title is very misleading - I'd say deliberately so.
