Forecasting Super-Sample Covariance in Future Weak Lensing Surveys with SuperSCRAM
Matthew C. Digman, Joseph E. McEwen, Christopher M. Hirata
The observable universe contains density perturbations on scales larger than any finite volume survey. Perturbations on scales larger than a survey can measure degrade its power to…
The clustering of the SDSS-IV extended Baryon Oscillation Spectroscopic Survey DR14 quasar sample: First measurement of Baryon Acoustic Oscillations between redshift 0.8 and 2.2
Metin Ata, Falk Baumgarten, Julian Bautista +60
We present measurements of the Baryon Acoustic Oscillation (BAO) scale in redshift-space using the clustering of quasars. We consider a sample of 147,000 quasars from the extended…
FAST-PT II: an algorithm to calculate convolution integrals of general tensor quantities in cosmological perturbation theory
Xiao Fang, Jonathan A. Blazek, Joseph E. McEwen +1
Cosmological perturbation theory is a powerful tool to predict the statistics of large-scale structure in the weakly non-linear regime, but even at 1-loop order it results in compu…
FAST-PT: a novel algorithm to calculate convolution integrals in cosmological perturbation theory
Joseph E. McEwen, Xiao Fang, Christopher M. Hirata +1
We present a novel algorithm, FAST-PT, for performing convolution or mode-coupling integrals that appear in nonlinear cosmological perturbation theory. The algorithm uses several p…
The effects of assembly bias on cosmological inference from galaxy-galaxy lensing and galaxy clusters
Joseph E. McEwen, David H. Weinberg
The combination of galaxy-galaxy lensing (GGL) and galaxy clustering is a promising route to measuring the amplitude of matter clustering and testing modified gravity theories of c…
Streaming velocities and the baryon-acoustic oscillation scale
Jonathan Blazek, Joseph E. McEwen, Christopher M. Hirata
At the epoch of decoupling, cosmic baryons had supersonic velocities relative to the dark matter that were coherent on large scales. These velocities subsequently slow the growth o…
The Photon Underproduction Crisis
Juna A. Kollmeier, David H. Weinberg, Benjamin D. Oppenheimer +9
We examine the statistics of the low-redshift Lyman-alpha forest from smoothed particle hydrodynamic simulations in light of recent improvements in the estimated evolution of the c…
The fishbone potential revisited
J. P. Day, J. E. McEwen, M. Elhanafy +3
The fishbone potential of composite particles simulates the Pauli effect by nonlocal terms. We determine the fishbone potential by simultaneously fitting to two- resonance…
Treatment of confinement in the Faddeev approach to three-quark problems
J. McEwen, J. Day, A. Gonzalez +2
A method is presented that allows to solve the Faddeev integral equations of the semirelativistic constituent quark model. In such a model the quark-quark interaction is modeled by…
Two-body problems with confining potentials
Joseph Day, Joseph McEwen, Zoltan Papp
A formalism is presented that allows an asymptotically exact solution of non-relativistic and semi-relativistic two-body problems with infinitely rising confining potentials. We co…
