Estimation of model parameters in the selected double imaged quasars

This article presents the results of modeling based on observations of the gravitationally lensed quasars SDSS J0806+2006 and SDSS J2124+1632 observed at the Maidanak Observatory in 2017-2022 and 2018-2022. The value of the Hubble constant H0= 61.4±7 for the SDSS J0806+2006 GLK is estimated, and the redshift of the lensing galaxy for the SDSS J2124+1632 GLK is found Zg = 0.245 ±0.071.

Abstract

This article presents the results of modeling based on observations of the gravitationally lensed quasars SDSS J0806+2006 and SDSS J2124+1632 observed at the Maidanak Observatory in 2017-2022 and 2018-2022. The value of the Hubble constant H0= 61.4±7 for the SDSS J0806+2006 GLK is estimated, and the redshift of the lensing galaxy for the SDSS J2124+1632 GLK is found Zg = 0.245 ±0.071.
