The X-ray Properties of Moderate-redshift Galaxy Groups Selected by Association with Gravitational Lenses
C. D. Fassnacht, D. D. Kocevski, M. W. Auger +5
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…

Mass Along the Line of Sight to the Gravitational Lens B1608+656: Galaxy Groups and Implications for H_0
C. D. Fassnacht, R. R. Gal, L. M. Lubin +3
We report the discovery of four groups of galaxies along the line of sight to the B1608+656 gravitational lens system. One group is at the redshift of the primary lensing galaxy (z…
