Accounting for Baryons in Cosmological Constraints from Cosmic Shear
Andrew R. Zentner, Elisabetta Semboloni, Scott Dodelson +3
One of the most pernicious theoretical systematics facing upcoming gravitational lensing surveys is the uncertainty introduced by the effects of baryons on the power spectrum of th…
The Weight of Emptiness: The Gravitational Lensing Signal of Stacked Voids
Elisabeth Krause, Tzu-Ching Chang, Olivier Doré +1
The upcoming new generation of spectroscopic galaxy redshift surveys will provide large samples of cosmic voids, the distinct, large underdense structures in the universe. Combinin…
Halo Occupation Distribution Modeling of Green Valley Galaxies
Elisabeth Krause, Christopher M. Hirata, Christopher Martin +2
We present a clustering analysis of near ultraviolet (NUV) - optical color selected luminosity bin samples of green valley galaxies. These galaxy samples are constructed by matchin…
A new third-order cosmic shear statistics: Separating E/B-mode correlations on a finite interval
Elisabeth Krause, Peter Schneider, Tim Eifler
Decomposing the shear signal into E and B-modes properly, i.e. without leakage of B-modes into the E-mode signal and vice versa, has been a long-standing problem in weak gravitatio…
