The Music of the Sphere: Exploring a Simple Universe in a Box¶
How much information does the CMB temperature map, on the surface of last scattering at z=1100, provide on the potential throughout the volume?

Generate fake CMB data on a Healpix sphere.¶
In [6]:
reload(universe)
f = universe.FakeHealpixData()
f.show()
Define a 2d slice through our universe.¶
In [7]:
s = universe.SliceSurface()
Infer the minimum variance ϕ field on this 2d slice.¶
In [8]:
inf = universe.Inference(f, s)
inf.calculate_mv_phi()
inf.view_phi_mv_slice()
