The effect of baryon cooling on the statistics of giant arcs and multiple quasars.

WAMBSGANSS J., OSTRIKER J.P. and BODE P.

Abstract (from CDS):

The statistics of giant arcs and large-separation lensed quasars provide powerful constraints for the parameters of the underlying cosmological model. So far, most investigations have been carried out using pure dark matter simulations. Here we present a recipe for including the effects of baryon cooling (i.e., large galaxy formation) in dark matter N-body simulations that is consistent with observations of massive galaxies. Then we quantitatively compare lensing with and without applying this baryon correction to the pure dark matter case. Including the baryon correction significantly increases the frequency of giant arcs and lensed quasars, particularly on scales of 10" and smaller: the overall frequency of multiple images with splittings larger than 3" increases by about 25% for source redshifts between zs=1.5 and 7.5. The baryon rearrangement also slightly increases the fraction of quadruple images over doubles.
