description We suggest that “<math display="inline"><mi>G</mi></math> objects” recently discovered in the Galactic Center may be clouds of gas bound by the gravitational field of stellar-mass black holes produced in the interactions of sublunar primordial black holes with neutron stars. If dark matter is composed of primordial black holes with masses <math display="inline"><mo stretchy="false">(</mo><msup><mn>10</mn><mrow><mo>-</mo><mn>16</mn></mrow></msup><mi>–</mi><msup><mn>10</mn><mrow><mo>-</mo><mn>10</mn></mrow></msup><mo stretchy="false">)</mo><msub><mi>M</mi><mo stretchy="false">⊙</mo></msub></math>, these black holes can be captured by neutron stars in the Galactic Center, where the dark matter density is high. After the capture, the neutron star is consumed by the black hole, resulting in a population of <math display="inline"><mo stretchy="false">(</mo><mn>1</mn><mo>-</mo><mn>2</mn><mo stretchy="false">)</mo><msub><mi>M</mi><mo stretchy="false">⊙</mo></msub></math> black holes. These stellar-mass black holes, accompanied by gaseous atmospheres, can account for the observed properties of the <math display="inline"><mi>G</mi></math> objects, including their resilience to tidal disruption by the supermassive black hole in the Galactic Center, while also producing emission consistent with inferred luminosities.

If dark matter is composed of primordial black holes with masses $(10^{-16} - 10^{-10}) M_\odot$, these black holes can be captured by neutron stars in the Galactic Center, where the dark matter density is high. After the capture, the neutron star is consumed by the black hole, resulting in a population of $(1-2) M_\odot $ black holes. These stellar-mass black holes, accompanied by gaseous atmospheres, can account for the observed properties of the $G$ objects, including their resilience to tidal disruption by the supermassive black hole in the Galactic Center while also producing emission consistent with inferred luminosities.arXiv:2308.08623IPMU23-0026oai:cds.cern.ch:28751572023-08-16
