The ‘triple’ quasar, PG1115 +08 (which actually contains at least four objects: A1, A2, B and C) was the second gravitational lens object to be found1. But because of its small angular scale (<2.5 arc s separation between components) and lack of detectable radio emission, which precludes the use of high-resolution interferometric radio techniques, not much is known about this object. In particular, the lensing object(s) have not been identified. Here we report imaging observations made on a… Expand
The quadruple gravitational lens PG 1115+080: Time delays and models
Optical photometry is presented for the quadruple gravitational lens PG 1115+080. A preliminary reduction of data taken from 1995 November to 1996 June gives component C leading component B by 23.7 ?Expand
The Microlensing Properties of a Sample of 87 Lensed Quasars
Gravitational microlensing is a powerful tool for probing the physical properties of quasar accretion disks and properties of the lens galaxy such as its dark matter fraction and mean stellar mass.Expand
An Infrared Einstein Ring in the Gravitational Lens PG 1115+080*
Hubble Space Telescope observations of the gravitational lens PG 1115+080 in the infrared show the known zl = 0.310 lens galaxy and reveal the zs = 1.722 quasar host galaxy. The main lens galaxy G isExpand
PG 1115+080: variations of the A2/A1 flux ratio and new values of the time delays
We report the results of our multicolor observations of PG 1115+080 with the 1.5-m telescope of the Maidanak Observatory (Uzbekistan, Central Asia) in 2001-2006. Monitoring data in filter R spanningExpand
A SHARP view of H0LiCOW: H0 from three time-delay gravitational lens systems with adaptive optics imaging
We present the measurement of the Hubble constant, H0, with three strong gravitational lens systems. We describe a blind analysis of both PG 1115+080 and HE 0435−1223 as well as an extension of ourExpand
Gravitational Lenses as Tools in Observational Cosmology
The study of gravitational lenses is intimately tied to observational cosmology. When we observe a gravitationally lensed quasar, we are viewing a single object along two or more neighboring pathsExpand
A spectroscopic study of the environments of gravitational lens galaxies
We present the first results from our spectroscopic survey of strong gravitational lens environments. Six of the eight lens galaxies in our sample belong to a poor group of galaxies, three of whichExpand
Determining the Hubble constant from the gravitational lens PG-1115+080
For the quadruple gravitational lens PG 1115+080, we combine recent measurements of the time delays with new lens models to determine the Hubble constant H_0. We explore the effects of systematicExpand
Determining the time delays in the gravitational lens PG 1115+080
A statistical analysis of published long-term photometric monitoring observations of the gravitationally lensed quasar PG 1115+080 in the optical is presented. This goal of this study is determiningExpand
The X-Ray Properties of Moderate-Redshift Galaxy Groups Selected by Association with Gravitational Lenses
We present results from a systematic investigation of the X-ray properties of a sample of moderate-redshift (0:3 < z < 0:6) galaxy groups. These groups were selected not by traditional X-ray orExpand
