Those are called massive compact halo objects (MACHOs). From &quot;Dark Matter: A Primer&quot; (https://arxiv.org/abs/1006.2483): To hunt for these objects two collaborations, the MACHO Collaboration and the EROS-2 Survey, searched for gravitational microlensing (the changing brightness of a distant object due to the interference of a nearby object) caused by possible MACHOs in the Milky Way halo. (Other collaborations have studied this as well, such as MOA, OGLE, and SuperMACHO.) The MACHO Collaboration painstakingly observed and statistically analyzed the skies for such lensing; 11.9…</p><p><a href="https://hackerpaper.kaipfister.de/p/1006.2483/">Paper and discussion history</a>.
