Constraining Galaxy Cluster Triaxiality via Weak Lensing --- I. Preparation for the Rubin Data Beyond Leading Order
Shenming Fu, Radhakrishnan Srinivasan, Tae-hyeon Shin +13
The 3D mass distributions of galaxy clusters are generally triaxial, a geometry that is difficult to constrain from projected observations. In this work, we measure the projected h…
Cluster Catalog Validation with Multiwavelength Data
Ethan K. Steelberg, Tesla E. Jeltema, Jackson H. O'Donnell +2
The Legacy Survey of Space and Time (LSST) will provide a ground-breaking data set for cosmology, but to achieve the precision needed, the data, data reduction, and algorithms meas…
High Redshift CDM Cosmology: To Bin or not to Bin?
Eoin Ó Colgáin, M. M. Sheikh-Jabbari, Rance Solomon
We construct observational Hubble and angular diameter distance mock data with baseline Planck CDM input values, before fitting the CDM model to study evolu…
Putting Flat CDM In The (Redshift) Bin
Eoin Ó Colgáin, M. M. Sheikh-Jabbari, Rance Solomon +2
Flat CDM cosmology is specified by two constant fitting parameters at the background level in the late Universe, the Hubble constant and matter density (today) . Math…
Revealing Intrinsic Flat CDM Biases with Standardizable Candles
Eoin Ó Colgáin, M. M. Sheikh-Jabbari, Rance Solomon +4
Emerging high redshift cosmological probes, in particular quasars (QSOs), show a preference for larger matter densities, , within the flat CDM framework. Here,…
Variability in Quasar Light Curves: using quasars as standard candles
Rance Solomon, Dejan Stojkovic
A relation between the variational slope, , and the mean absolute magnitude, , in the light curves of 58 spectroscopically confirmed quasars is measured wi…
