Impact of inhomogeneous reionization on post-reionization 21 cm intensity mapping measurement of cosmological parameters
Heyang Long, Catalina Morales-Gutiérrez, Paulo Montero-Camacho +1
21 cm intensity mapping (IM) has the potential to be a strong and unique probe of cosmology from redshift of order unity to redshift potentially as high as 30. For post-reionizatio…
Probing Large Scale Ionizing Background Fluctuation with Lyman Forest and Galaxy Cross-correlation at z=2.4
Heyang Long, Christopher M. Hirata
The amplitude of the metagalactic ultraviolet background (UVB) at large-scales is impacted by two factors. First, it naturally attenuates at scales larger than mean-free-path of UV…
A Synthetic Roman Space Telescope High-Latitude Time-Domain Survey: Supernovae in the Deep Field
Kevin X. Wang, Dan Scolnic, M. A. Troxel +14
NASA will launch the Nancy Grace Roman Space Telescope (Roman) in the second half of this decade, which will allow for a generation-defining measurement of dark energy through mult…
Weak Gravitational Lensing Shear Estimation with Metacalibration for the Roman High-Latitude Imaging Survey
Masaya Yamamoto, M. A. Troxel, Mike Jarvis +5
We investigate the performance of the Metacalibration shear calibration framework using simulated imaging data for the Nancy Grace Roman Space Telescope (Roman) reference High-Lati…
