Scale-dependent halo bias from scale-dependent growth
Kyle Parfrey, Lam Hui, Ravi K. Sheth
We derive a general expression for the large-scale halo bias, in theories with a scale-dependent linear growth, using the excursion set formalism. Such theories include modified gr…
Equivalence Principle Implications of Modified Gravity Models
Lam Hui, Alberto Nicolis, Christopher Stubbs
Theories that attempt to explain the observed cosmic acceleration by modifying general relativity all introduce a new scalar degree of freedom that is active on large scales, but i…
Lensing Bias in Cosmic Shear
Fabian Schmidt, Eduardo Rozo, Scott Dodelson +2
Only galaxies bright enough and large enough to be unambiguously identified and measured are included in galaxy surveys used to estimate cosmic shear. We demonstrate that because g…
Size Bias in Galaxy Surveys
Fabian Schmidt, Eduardo Rozo, Scott Dodelson +2
Only certain galaxies are included in surveys: those bright and large enough to be detectable as extended sources. Because gravitational lensing can make galaxies appear both brigh…
The Origin of the Universe as Revealed Through the Polarization of the Cosmic Microwave Background
S. Dodelson, R. Easther, S. Hanany +61
Modern cosmology has sharpened questions posed for millennia about the origin of our cosmic habitat. The age-old questions have been transformed into two pressing issues primed for…
