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…
Unified dark sector approaches to cosmological tensions
Sergio Sevillano Muñoz, Mark Trodden
We present an analytical study of minimal mass-varying dark matter models, in which a single scalar field controls the dark matter mass, focusing on their utility in simultaneously…
The Revised Evolutionary Volume Tolman Test: Cosmological Constraints from Galaxy Evolution
Christopher J. Conselice, Edmund J. Copeland, Sergio Sevillano Muñoz
In this study we adapt a classical cosmology measurement, the volume or number density test, to a modern synthesis of observed galaxy evolution. We do this by using measured galaxy…
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…
