Dissecting the thermal Sunyaev-Zeldovich-gravitational lensing cross-correlation with hydrodynamical simulations
Alireza Hojjati, Ian G. McCarthy, Joachim Harnois-Deraps +4
We use the cosmo-OWLS suite of cosmological hydrodynamical simulations, which includes different galactic feedback models, to predict the cross-correlation signal between weak grav…
Next Generation Strong Lensing Time Delay Estimation with Gaussian Processes
Alireza Hojjati, Eric V. Linder
Strong gravitational lensing forms multiple, time delayed images of cosmological sources, with the "focal length" of the lens serving as a cosmological distance probe. Robust estim…
Strong Lens Time Delay Challenge: II. Results of TDC1
Kai Liao, Tommaso Treu, Phil Marshall +23
We present the results of the first strong lens time delay challenge. The motivation, experimental design, and entry level challenge are described in a companion paper. This paper…
Observable physical modes of modified gravity
Alireza Hojjati, Levon Pogosian, Alessandra Silvestri +1
At linear order in cosmological perturbations, departures from the growth in the cosmological standard model can be quantified in terms of two functions of redshift and Fourier…
