The EDGES measurement disfavors an excess radio background during the cosmic dawn

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 …

Effect of Snapshot Integration

I was recently wondering what the effect of snapshot integration is on the power spectrum. I think I have a good handle on it now, but I wanted to write it down for posterity.

FORWARD featured image

FORWARD

FORWARD is the name of my Marie Sklodowska-Curie Fellowship. It's not an acronym: it is short for "Forward-Models of Cosmic Dawn: connecting 21cm simulations to the real world". …

matvis featured image

matvis

`matvis` is a visibility simulator: it computes what an interferometer (like [HERA](/projects/hera)) would measure given a model of the sky. This process is incredibly …
