Geometry of obscurer from X-ray spectra
Luminosity function
Heavily obscured AGN
Obscured, CTK fraction
f(L,z)
Obscured, CTK fraction
by galaxy gas f(M*,z)
SMBH occupation f(M*,z)
Hierarchical Bayesian Models
Nested Sampling & PyMultiNest
Cosmological Sims
Spectral fitting with low counts (BXA)
Multi-wavelength Association NWAY
Bayes factor
Angular separation
Positional uncertainties
Weighting term (mag, colors,etc)
posterior probability for match between X-ray source i & a potential counterpart j
depends on
counterpart sky number density ρs and expected counterpart fraction ηx
