Extending SOMPZ beyond Spectroscopic Coverage for Roman Weak Lensing
Yufei Zhen, Chun-Hao To, Boyan Yin +7
Precision weak lensing cosmology requires accurate galaxy redshift distributions. However, the spectroscopic samples used to characterize these distributions do not fully span the…
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…
Highly Efficient Selection of High-Redshift Emission-Line Galaxies for future DESI-like surveys with Deep Multi-band Imaging
Yoquelbin Salcedo Hernandez, Jeffrey A. Newman, Brett. H. Andrews +53
Emission-line galaxies (ELGs) are an important tracer of baryon acoustic oscillations (BAO) and large-scale structure (LSS) at . In this work, we investigate the feasibility…
Optimizing Deep Learning Photometric Redshifts for the Roman Space Telescope with HST/CANDELS
Ashod Khederlarian, Brett H. Andrews, Jeffrey A. Newman +2
Photometric redshifts (photo-'s) will be crucial for studies of galaxy evolution, large-scale structure, and transients with the Nancy Grace Roman Space Telescope. Deep learning…
Modeling Redshift Uncertainties in Roman Weak Lensing Cosmology
Diogo H. F. de Souza, Boyan Yin, Tim Eifler +7
Cosmological constraints using weak gravitational lensing measurements from the Roman Space Telescope will require a powerful method for modelling uncertainties in the galaxy redsh…
Electron temperature relations and the direct N, O, Ne, S and Ar abundances of 49959 star-forming galaxies in DESI Data Release 2
D. Scholte, F. Cullen, J. Moustakas +42
We present the largest direct-method abundance catalogue of galaxies to date, containing measurements of 49959 star-forming galaxies at z < 0.96 from DESI Data Release 2. By direct…
