Abstract We estimate the Einstein-radius-enclosed total mass for 177 cluster-scale strong gravitational lenses identified by ChicagO Optically selected Lenses Located At Margins of Public Surveys (COOL-LAMPS) collaboration with lens redshifts ranging from 0.2 ⪅ z 1.0 using brightest-cluster-galaxy (BCG) redshift and an observable proxy Einstein radius. constrain luminosity stellar fitting parametric spectral energy distributions to aperture photometry Dark Energy Camera Legacy Survey...
Abstract We report the discovery of COOL J0335−1927, a quasar at z = 3.27 lensed into three images with maximum separation 23.″3 by galaxy cluster 0.4178. To date, this is highest redshift wide-separation known. In addition, J0335−1927 shows several strong intervening absorbers visible in spectra all varying equivalent widths. The also mini-broad line absorption. construct parametric gravitational lens model using ground-based imaging, constrained and positions as well other multiply imaged...
We compute parametric measurements of the Einstein-radius-enclosed total mass for 177 cluster-scale strong gravitational lenses identified by ChicagO Optically-selected Lenses Located At Margins Public Surveys (COOL-LAMPS) collaboration with lens redshifts ranging from $0.2 \lessapprox z 1.0$ using only two measured parameters in each lensing system: Einstein radius, and brightest-cluster-galaxy (BCG) redshift. then constrain luminosity stellar fitting spectral energy distributions (SEDs)...
In this work we use simulated qubit data to quantify the rate at which jumps are found using point by jump finding code as a function of size. We then efficiencies adjust our rates and add uncertainties. also calculate efficiency correlated error for qubits 1 2 3 4.
Wide-separation lensed quasars (WSLQs) are a rare class of strongly quasars, magnified by foreground massive galaxy clusters, with typically large magnifications the multiple quasar images. They relatively unexplored opportunity for detailed study host galaxies. The current small sample known WSLQs has median redshift $z\approx 2.1$, larger than most other samples galaxies studied to date. Here, we derive precise constraints on properties six and their galaxies, using parametric surface...
