"A Calibration of the Stellar-mass Fundamental Plane at
So-called "stellar" masses for early type galaxies are almost always
determined by one of two methods: either they are estimated from
spectra (and sometimes only broad band colors) or they are deduced by
subtracting the contribution of an assumed dark matter profile from a
combined mass inferred from kinematic (and sometimes macro-lensing)
measurements. Both methods have shortcomings. We describe a third
method: the analysis of flux ratio anomalies caused by the
micro-lensing of quadruply imaged quasars by the stellar graininess of
the lensing galaxy (Schechter and Wambsganss 2004). We use X-ray
observations from the Chandra Observatory (Pooley et al 2012) to
measure flux ratio anomalies and the "stellar mass fundamental plane"
of Hyde and Bernardi (2009) to average results obtained at
different radii from galaxies of different sizes and at different
redshifts. We infer limits on the underlying stellar intial mass
function. Massachusetts Institute of Technology host: Pawan Kumar |
