A new physical model within the popular 21cmFAST simulation code that allows for the efficient generation of discrete galaxy populations and their associated radiation fields, over …
We re-analyze the same EDGES data that sparked a rush of interest in exotic dark matter models and excess radio backgrounds, finding that accounting for both the possibility of …
We introduce matvis, a GPU-accelerated matrix-based visibility simulator for many-element 21 cm arrays that allows simulation of mock observations on unprecedented scales.
A new method for computing the power of 21cm experiments to detect the cosmological 21cm signal.
We present 21cmEMU, a machine learning-based emulator of the popular 21cmFAST simulation code. 21cmEMU can rapidly generate predictions for summary observables like the global 21 …
I gave an invited scientific overview of EoR, Cosmic Dawn, and Italy's involvement in the SKA.
I wrote this memo quite a while back, trying to get some power spectrum noise calculations correct. I’ve shared it a few times with different folks, so I thought I’d put it up here …
Cosmic Dawn refers to the time in the Universe’s past when the first stars and galaxies burst into life. We know such a time exists, simply because we know there was a time without …
