Supernova microlensing as a probe of ultracompact minihalos and primordial cosmology
Djuna Croon, Sergio Sevillano Muñoz, Miguel Zumalacarregui
We propose using supernova microlensing to search for ultracompact minihalos and other extended dark structures seeded by enhanced primordial small-scale power. Unlike conventional…
Caustic crossings in giant arcs with extended dark matter objects
Djuna Croon, Benedict Crossey, Jose Maria Diego +2
Caustic-crossing stars observed in giant arcs behind galaxy clusters provide a powerful probe of dark matter substructure. While previous work has focused on point-like lenses such…
Dark Classification Matters: Searching for Primordial Black Holes with LSST
Miguel Crispim Romao, Djuna Croon, Benedict Crossey +1
We present projected constraints on the abundance of primordial black holes (PBHs) as a constituent of dark matter, based on microlensing observations from the upcoming Legacy Surv…
Updated constraints on the primordial power spectrum at sub-Mpc scales
Torsten Bringmann, Djuna Croon, Sergio Sevillano Muñoz
The primordial power spectrum of matter density perturbations contains highly valuable information about new fundamental physics, in particular cosmological inflation, but is only…
Repository for extended dark matter object constraints
Djuna Croon, Sergio Sevillano Muñoz
Extended dark matter objects (EDOs) are popular dark matter candidates that interact gravitationally with the Standard Model. These gravitational interactions can be used to constr…
Cosmic microwave background constraints on extended dark matter objects
Djuna Croon, Sergio Sevillano Muñoz
Primordially formed extended dark objects would accrete baryonic matter and impact the ionisation history of the Universe. Insisting on consistency with the anisotropies of the cos…
