Lensing is Low: Cosmology, Galaxy Formation, or New Physics?
Alexie Leauthaud, Shun Saito, Stefan Hilbert +19
We present high signal-to-noise galaxy-galaxy lensing measurements of the BOSS CMASS sample using 250 square degrees of weak lensing data from CFHTLenS and CS82. We compare this si…
Weak lensing by galaxy troughs with modified gravity
Alexandre Barreira, Sownak Bose, Baojiu Li +1
We study the imprints that theories of gravity beyond GR can leave on the lensing signal around line of sight directions that are predominantly halo-underdense (called troughs) and…
Validating estimates of the growth rate of structure with modified gravity simulations
Alexandre Barreira, Ariel G. Sánchez, Fabian Schmidt
We perform a validation of estimates of the growth rate of structure, described by the parameter combination , in modified gravity cosmologies. We consider an analysis pipeli…
RAY-RAMSES: a code for ray tracing on the fly in N-body simulations
Alexandre Barreira, Claudio Llinares, Sownak Bose +1
We present a ray tracing code to compute integrated cosmological observables on the fly in AMR N-body simulations. Unlike conventional ray tracing techniques, our code takes full a…
