A unified linear intrinsic alignment model for elliptical and disc galaxies and the resulting ellipticity spectra
Basundhara Ghosh, Kai Nussbaumer, Eileen Sophie Giesel +1
Alignments of spiral galaxies were thought to result from tidal torquing, where tidal field of the cosmic large-scale structure exert torquing moments onto dark matter haloes, dete…
Etherington duality breaking: gravitational lensing in non-metric spacetimes versus intrinsic alignments
Eileen Sophie Giesel, Basundhara Ghosh, Björn Malte Schäfer
The Etherington distance duality relation is well-established for metric theories of gravity, and confirms the duality between the luminosity distance and the angular diameter dist…
Intrinsic and extrinsic gravitational flexions
Eileen Sophie Giesel, Basundhara Ghosh, Bjoern Malte Schaefer
The topic of this paper is a generalisation of the linear model for intrinsic alignments of galaxies to intrinsic flexions: In this model, third moments of the brightness distribut…
Information geometry in cosmological inference problems
Eileen Giesel, Robert Reischke, Björn Malte Schäfer +1
Statistical inference more often than not involves models which are non-linear in the parameters thus leading to non-Gaussian posteriors. Many computational and analytical tools ex…
