Those weird blobs at the center of the galaxy might actually be 'zombie stars' being eaten from the inside out by tiny black holes.

The Takeaway
Astronomers have been puzzled by 'G-objects'—mysterious blobs that look like gas clouds but act like solid stars. This paper suggests they are actually neutron stars being hollowed out by microscopic black holes created during the Big Bang. This theory explains both their weird behavior and solves the decades-old mystery of why the 'normal' dead stars we expect to see at the galactic center are missing.
From the abstract
The nature of the so-called G objects orbiting the Galactic Center remains unresolved. These sources exhibit compact Br$\gamma$ emission, extreme infrared colors, and remarkable dynamical stability through close passages to the central supermassive black hole, challenging conventional interpretations as stars or unbound gas clouds. We investigate the hypothesis that G objects are the remnants of neutron stars that have been converted into low-mass black holes through the capture of primordial bl
