Spectroscopic Redshifts for Seven Lens Galaxies
Eran O. Ofek, Dan Maoz, Hans-Walter Rix +2
We report VLT observations of 11 lensed quasars, designed to measure the redshifts of their lens galaxies. We successfully determined the redshifts for seven systems, five of which…
The Lensed Arc Production Efficiency of Galaxy Clusters: A Comparison of Matched Observed and Simulated Samples
Assaf Horesh, Eran O. Ofek, Dan Maoz +3
We compare the statistical properties of giant gravitationally lensed arcs produced in matched simulated and observed cluster samples. The observed sample consists of 10 X-ray sele…
Discovery of Multiply Imaged Galaxies behind the Cluster and Lensed Quasar SDSS J1004+4112
Keren Sharon, Eran O. Ofek, Graham P. Smith +7
We have identified three multiply imaged galaxies in Hubble Space Telescope images of the redshift z=0.68 cluster responsible for the large-separation quadruply lensed quasar, SDSS…
The Remnants of Intergalactic Supernovae
Dan Maoz, Eli Waxman, Abraham Loeb
Intergalactic type-Ia supernovae (SNe-Ia) have been discovered recently in rich galaxy clusters, likely the descendants of an intergalactic stellar population found in recent years…
Multiwavelength Monitoring of the Dwarf Seyfert 1 Galaxy NGC 4395. I. A Reverberation-Based Measurement of the Black Hole Mass
Bradley M. Peterson, Misty C. Bentz, Louis-Benoit Desroches +8
A reverberation-mapping program on NGC 4395, the least-luminous known Seyfert 1 galaxy, undertaken with the Space Telescope Imaging Spectrograph on the Hubble Space Telescope, yiel…
Determination of stellar shape in microlensing event MOA 2002-BLG-33
N. J. Rattenbury, F. Abe, D. P. Bennett +30
We report a measurement of the shape of the source star in microlensing event MOA 2002-BLG-33. The lens for this event was a close binary whose centre-of-mass passed almost directl…
