Mitigating baryonic effects with a theoretical error covariance
Maria G. Moreira, Felipe Andrade-Oliveira, Xiao Fang +5
One of the primary sources of uncertainties in modeling the cosmic-shear power spectrum on small scales is the effect of baryonic physics. Accurate cosmology for Stage-IV surveys r…
Dark Energy Survey Year 1 Results: Constraining Baryonic Physics in the Universe
Hung-Jin Huang, Tim Eifler, Rachel Mandelbaum +74
Measurements of large-scale structure are interpreted using theoretical predictions for the matter distribution, including potential impacts of baryonic physics. We constrain the f…
Cosmology with the Wide-Field Infrared Survey Telescope -- Synergies with the Rubin Observatory Legacy Survey of Space and Time
Tim Eifler, Melanie Simet, Elisabeth Krause +27
We explore synergies between the space-based Wide-Field Infrared Survey Telescope (WFIRST) and the ground-based Rubin Observatory Legacy Survey of Space and Time (LSST). In particu…
Modeling baryonic physics in future weak lensing surveys
Hung-Jin Huang, Tim Eifler, Rachel Mandelbaum +1
Modifications of the matter power spectrum due to baryonic physics are one of the major theoretical uncertainties in cosmological weak lensing measurements. Developing robust mitig…
An Analysis Framework for Understanding the Origin of Nuclear Activity in Low-Power Radio Galaxies
Yen-Ting Lin, Hung-Jin Huang, Yen-Chi Chen
Using large samples containing nearly active galaxies of low radio luminosity (1.4 GHz luminosity between and W/Hz, essentially low-excit…
