Report by the ESA-ESO Working Group on Extra-Solar Planets
M. Perryman, O. Hainaut, D. Dravins +14
Various techniques are being used to search for extra-solar planetary signatures, including accurate measurement of radial velocity and positional (astrometric) displacements, grav…
The dark matter content of lensing galaxies at 1.5 R_e
Paul L. Schechter, Joachim Wambsganss
Many gravitationally lensed quasars exhibit flux ratio "anomalies" that cannot be explained under the hypothesis that the lensing potential is smooth on scales smaller than one kpc…
PLANET II: A Microlensing and Transit Search for Extrasolar Planets
Penny D. Sackett, M. D. Albrow, J. -P. Beaulieu +16
Due to their extremely small luminosity compared to the stars they orbit, planets outside our own Solar System are extraordinarily difficult to detect directly in optical light. Ca…
The Search for Matter with Gravitational Lensing
Joachim Wambsganss
Gravitational lensing is a powerful tool to detect compact matter on very different mass scales. Of particular importance is the fact that lensing is sensitive to both luminous and…
Gravitational Lensing - A brief review
Joachim Wambsganss
Gravitational lensing has established itself as a valuable tool in many astrophysical fields in the roughly 20 years of its existence as an observational science. In this brief rev…
Microlensing results from APO monitoring of the double quasar Q0957+561A,B between 1995 and 1998
Joachim Wambsganss, Robert W. Schmidt, Wesley N. Colley +2
If the halo of the lensing galaxy 0957+561 is made of massive compact objects (MACHOs), they must affect the lightcurves of the quasar images Q0957+561 A and B differently. We sear…
