Combining Rubin and Roman photometry and its implications for photometric redshift estimation
Tae-hyeon Shin, Rachel Mandelbaum, Chun-Hao To +14
We perform a joint Roman--Rubin photometry analysis using the LSST Science Pipelines (LSP) on simulated images, by using the Roman F158 band as the reference band and applying forc…
Weak-Lensing Shear Response for Photometric Redshift-Based Tomographic Binning
Xiangchong Li, Tianqing Zhang, Rachel Mandelbaum +1
Dividing source galaxies into tomographic redshift bins is a cornerstone of modern weak gravitational lensing analyses, enabling measurements of the growth of cosmic structure and…
An LSST-DESC Precursor Project: Hyper Suprime-Cam Year 1 pt in Harmonic Space
D. Sanchez-Cid, J. Sanchez, I. Sevilla-Noarbe +19
We present the first fully photometric joint analysis of weak gravitational lensing and galaxy clustering (32pt) in harmonic space with LSST-DESC analysis pipelines applied…
Robust Photometry for Roman High-Latitude Imaging Survey Cosmology Using Roman and Rubin Imaging
Chun-Hao To, Tae-Hyeon Shin, Chihway Chang +18
Accurate and precise photometry is essential for Roman cosmology because it affects photometric-redshift performance, galaxy and cluster selection, tomographic binning, and redshif…
The Galaxy Luminosity Functions in ASTRID: Predictions for LSST
Fatemeh Hafezianzadeh, Tianqing Zhang, Paul Rogozenski +6
We present validated and forward-modelled galaxy luminosity functions and photometric predictions for the Vera C. Rubin Observatory Legacy Survey of Space and Time using the ASTRID…
cosmo-numba: B-modes and COSEBIs computations accelerated by Numba
Axel Guinot, Rachel Mandelbaum
Weak gravitational lensing is a widely used probe in cosmological analysis. It allows astrophysists to understand the content and evolution of the Universe. We are entering an era…
Optimizing the Roman Space Telescope High-Latitude Wide Area Survey for mitigating chromatic PSF effects on shear measurement
Federico Berlfein, Rachel Mandelbaum, Jiachuan Xu +1
Chromatic point-spread-function (PSF) effects arise from differences between the spectral energy distributions (SEDs) of stars, used to model the PSF, and galaxies, used to measure…
Diagnosing the Effects of Spectroscopic Training Set Imperfection on Photometric Redshift Performance
Alice Crafford, Alex I. Malz, Tianqing Zhang +11
Most LSST extragalactic science will rely on photometric redshifts (photo-) to extract distance information for the galaxies. However, an incomplete or non-representative traini…
