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…
matvis: A matrix-based visibility simulator for fast forward modelling of many-element 21 cm arrays
Piyanat Kittiwisit, Steven G. Murray, Hugh Garsden +95
Detection of the faint 21 cm line emission from the Cosmic Dawn and Epoch of Reionisation will require not only exquisite control over instrumental calibration and systematics to a…
Bayesian estimation of cross-coupling and reflection systematics in 21cm array visibility data
Geoff G. Murphy, Philip Bull, Mario G. Santos +76
Observations with radio arrays that target the 21-cm signal originating from the early Universe suffer from a variety of systematic effects. An important class of these are reflect…
