Research Proposals

Mediterranean upward-going-source geometry gives KM3NeT/ARCA substantially better OC sensitivity than IceCube. Primary neutrino instrument for this target.

Directional high-energy neutrino analysis at the Häberle IMBH candidate position. OC at declination −47° is a downward-going source for IceCube — higher atmospheric background than for northern-sky targets.

Gamma-ray technosignature search across accretion, jet, and beam-leakage scenarios. CTA-South provides Southern-hemisphere sensitivity above 100 GeV.

Pulsar-timing program to map OC's gravitational potential and constrain the IMBH mass profile via post-Keplerian timing residuals.

Deeper version of the MeerKAT mass-profile program: longer integrations, more pulsars, tighter constraints on the central potential.

Narrowband radio beacon search at L-band and S-band toward the cluster core. SETI-style spectral analysis.

IR spectroscopic search for chemical signatures of managed tidal disruption events versus a naturally gas-starved core. The two scenarios are electromagnetically degenerate; chemical fingerprints proposed as the discriminant.

Tightening photometric upper limits on accretion luminosity around the IMBH candidate. Builds on Chen et al. (2025) non-detection.

Continuous gravitational-wave search at the IMBH position combined with UHECR directional analysis from Pierre Auger.

Direct orbital constraints on the seven Häberle fast-moving stars from the next-generation 39 m European Extremely Large Telescope.

Multi-epoch astrometric monitoring of the seven Häberle stars to refine the IMBH mass and test for non-Keplerian motion.
