Fuzzy Dark Matter Halo Mass Functions at Cosmic Dawn
Raghunath Ghara, Adam Lidz, Daniel Grin +1
In fuzzy dark matter (FDM) cosmological models, wave effects impact astrophysical length scales, suppressing the abundance of small mass dark matter halos, and delaying the earlies…

Fuzzy Dark Matter Constraints from the Hubble Frontier Fields
Jackson Sipple, Adam Lidz, Daniel Grin +1
In fuzzy dark matter (FDM) cosmologies, the dark matter consists of ultralight bosons ( eV). The astrophysically large de Broglie wavelengths of such particles h…

Using HI observations of low-mass galaxies to test ultra-light axion dark matter
James T. Garland, Karen L. Masters, Daniel Grin
We evaluate recent and upcoming low-redshift neutral hydrogen (HI) surveys as a cosmological probe of small scale structure with a goal of determining the survey criteria necessary…
