Special Markowitz: Thermodynamic Formalism for the Joint Regularisation of Returns and Covariance
David Reinhardt
Special Markowitz (SM) regularises returns and covariance jointly, relative to a reference state (mu_ref, Sigma_ref). Each eigendirection of the whitened relative operator carries…

Determining our peculiar velocity from the aberration in the cosmic microwave background
Ralf Aurich, David Reinhardt
The motion of our solar system relative to the CMB rest frame leads to subtle distortions in the observed CMB sky map due to the aberration effect. Usually the corresponding peculi…
