Dark matter may be in the form of non-baryonic structures such as compact subhalos and boson stars. Structures weighing between asteroid and solar masses may be discovered via gravitational microlensing, an astronomical probe that has in the past helped constrain the population of primordial black holes and baryonic MACHOs. We investigate the non-trivial effect of the size of and density distribution within these structures on the microlensing signal, and constrain their populations using the EROS-2 and OGLE-IV surveys. Structures larger than a solar radius are generally constrained more weakly than point-like lenses, but stronger constraints may be obtained for structures with mass distributions that give rise to caustic crossings or produce larger magnifications.

  1. Gravitational Waves From Dark Binaries With Finite-Range Dark Forces

    gr-qc 2024-12 conditional novelty 7.0 of 10

    A finite-range dark force between dark-matter binaries sharpens and enhances the predicted gravitational wave background, adding knee features tied to the mediator mass.

  2. Constraining Dark Photon Dark Matter with Radio Silence from Soliton Mergers around Supermassive Black Holes

    hep-ph 2025-09 conditional novelty 6.0 of 10

    Non-observation of radio bursts from soliton mergers around supermassive black holes constrains dark photon solitons to make up less than about 1% of dark matter, with future surveys reaching 0.2%.

  3. Wide binaries in ultra-faint dwarf galaxies as a probe of extended dark objects

    hep-ph 2026-07 conditional novelty 5.0 of 10

    Wide binaries in Boötes I exclude dark-matter fractions down to ~10^-3 to 10^-2 for extended dark objects between 0.1 and 3000 solar masses with radii up to 10^7 solar radii, implying P_R ≲ 5×10^-6 at k ≈ 4×10^2-3×10^...
