If stop talking about Wallen is just "a small change." What are the bigger changes you want to see?

Absolutely, it's his favourite way to relax in the evening ❤️

...which we didn't expect! We plan further work to understand it better.

What does this all mean? We should model Fourier coefficients of the GWB, not PSDs! By modelling PSDs, we assume Gaussianity, which we have shown to mismodel the statistics of the astrophysical GWB.

Happy reading! 📖 (4/4)

...under-estimate the tails of the distribution.

Additionally, we found that finite observation introduces a covariance term in our statistics. While small, it may be significant enough at the lowest frequencies for high amplitude sources. This is also a source of non-Gaussianity... (3/4)

At low frequencies, the Gaussian approximation is fine. But at frequencies with few sources, we really need to stop assuming Gaussianity!

We find that Poisson variance (aka "shot noise") drives non-Gaussianity when there are very few sources. Modelling this region as Gaussian can... (2/4)

Welp, don’t you dare shill on astrobites…
