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...
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)...
ABSTRACT Two decades on, the study of hypervelocity stars is still in its infancy. These can provide novel constraints on total mass Galaxy and dark matter distribution. However how these are accelerated to such high velocities unclear. Various proposed production mechanisms for be distinguished using chemo-dynamic tagging. The advent Gaia other large surveys have provided hundreds candidate hyper velocity objects target ground-based high-resolution follow-up observations. We conduct...
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...
