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…

OzDES Reverberation Mapping of Active Galactic Nuclei: Final Data Release, Black-Hole Mass Results, & Scaling Relations

H. McDougall, T. M. Davis, Z. Yu +53

Over the last decade, the Australian Dark Energy (OzDES) collaboration has used Reverberation Mapping to measure the masses of high redshift supermassive black holes. Here we prese…

Accurate modeling for 32pt analyses in Roman and Rubin: a study of model approximations

Junzhou Zhang, Chihway Chang, Jiachuan Xu +6

One of the pillars of modern cosmology is the use of galaxy imaging surveys to extract information from the large-scale structure. In recent surveys, this measurement is typically…

Calibrating optical galaxy cluster projection effects with sparse spectroscopic samples: A clustering redshift approach

Lei Yang, Hao-Yi Wu, Tesla Jeltema +3

Wide-field optical imaging surveys are efficient at identifying galaxy clusters, but optically identified clusters suffer from projection effects--physically unassociated galaxies…

Impact of projection-induced optical selection bias on the weak lensing mass calibration of galaxy clusters

Titus Nyarko Nde, Hao-Yi Wu, Shulei Cao +4

Weak gravitational lensing signals of optically identified clusters are impacted by a selection bias -- halo triaxiality and large-scale structure along the line of sight simultane…
