Recovering 21cm Monopole Signals Without Smoothness
We expect the monopole signal at the lowest frequencies below $100\,$MHz to be composed to two components: the deep Rayleigh-Jeans tail of the cosmic microwave background and two distinct features: the dark ages trough at $\sim 17\,$MHz and the cosmic dawn trough at $\sim 75\,$Mhz. These are hidden...
