Limits on the Transverse Velocity of the Lensing Galaxy in Q2237+0305 from the Lack of Strong Microlensing Variability
Rodrigo Gil-Merino, Joachim Wambsganss, Luis J. Goicoechea +1
We present a method for the determination of upper limits on the transverse velocity of the lensing galaxy in the quadruple quasar system Q2237+0305, based on the lack of strong mi…
Size is Everything: Universal Features of Quasar Microlensing with Extended Sources
Michael J. Mortonson, Paul L. Schechter, Joachim Wambsganss
We examine the effect that the shape of the source brightness profile has on the magnitude fluctuations of images in quasar lens systems due to microlensing. We do this by convolvi…
Lensing Survey of the Most X-Ray Luminous Galaxy Clusters
W. Kausch, S. Schindler, T. Kronberger +4
We present the first three galaxy clusters of a larger sample of the most X-ray luminous galaxy clusters selected from the ROSAT Bright Survey. This project, which is a systematic…
Potential Direct Single-Star Mass Measurement
H. Ghosh
We analyze the lightcurve of the microlensing event OGLE-2003-BLG-175/MOA-2003-BLG-45 and show that it has two properties that, when combined with future high resolution astrometry…
Gravitational lensing in a concordance LCDM universe: The importance of secondary matter along the line of sight
Joachim Wambsganss, Paul Bode, Jeremiah P. Ostriker
To date, in almost all strong gravitational lensing analyses for modeling giant arc systems and multiple quasar images, it has been assumed that all the deflecting matter is concen…
OGLE-2003-BLG-238: Microlensing Mass Estimate of an Isolated Star
Guangfei Jiang, D. L. DePoy, A. Gal-Yam +38
Microlensing is the only known direct method to measure the masses of stars that lack visible companions. In terms of microlensing observables, the mass is given by M=(c^2/4G)\tild…
