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…

Quasar standardization: Overcoming Selection Biases and Redshift Evolution

Maria Giovanna Dainotti, Giada Bardiacchi, Aleksander Lukasz Lenart +5

Quasars (QSOs) are extremely luminous active galatic nuclei currently observed up to redshift . As such, they have the potential to be the next rung of the cosmic distance…

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,…
