Open research on Omega Centauri and its candidate IMBH: papers, tools and observing proposals.

The Milky Way's largest globular cluster may host an intermediate-mass black hole. Measurements here carry their citations, and the Macro Transcension Hypothesis is labeled as speculation wherever it appears.

Research

Papers

Working papers on the IMBH evidence, the mass tension between kinematics and pulsar timing, inward-migration economics and the technosignature campaign.

Read the papers → Interactive

Tools

Browser calculators, staged workflows and chained scenarios that read the same measurement file, so every number traces to a source.

Open the tools → Observation

Proposals

Drafted observing proposals across radio, infrared, gamma-ray, neutrino and gravitational-wave channels, each tied to a falsification criterion.
