Redshift evolution of the X-ray and UV luminosity relation of quasars: calibrated results from SNe Ia
Xiaolei Li, Ryan E. Keeley, Arman Shafieloo
Quasars could serve as standard candles if the relation between their ultraviolet and X-ray luminosities can be accurately calibrated. Previously, we developed a model-independent…
Litmus tests of the flat CDM model and model-independent measurement of with LSST and DESI
Benjamin L'Huillier, Ayan Mitra, Arman Shafieloo +2
In this analysis we apply a model-independent framework to test the flat CDM cosmology using simulated SNIa data from the upcoming Legacy Survey of Space and Time (LSST) and com…
JWST Lensed quasar dark matter survey II: Strongest gravitational lensing limit on the dark matter free streaming length to date
Ryan E. Keeley, Anna M. Nierenberg, Daniel Gilman +20
This is the second in a series of papers in which we use JWST MIRI multiband imaging to measure the warm dust emission in a sample of 31 multiply imaged quasars, to be used as a pr…
