Witt’s hyperbola is both predicted and observed to pass close to the lensing galaxies in quadruple quasars

Kavli Affiliate: Paul Schechter | Summary:When a rectangular hyperbola is constructed from the image positions of a quadruply lensed quasar, as proposed by Witt (1996), it passes very close to the the lensing galaxy. The median measured perpendicular offset between the observed light center of the lens and Witt’s hyperbola is 0.013" for a sample […]

Galaxies lensing quadruply imaged quasars lie close to the centers of their lensing potentials

Kavli Affiliate: Paul L. Schechter | First 5 Authors: Paul L. Schechter, Richard Luhtaru, , , | Summary: In modeling the potentials of quadruply lensed quasars, investigators often employ models for the stellar surface brightness profile of the lensing galaxy for the sole purpose of eliminating its contamination of the light from the quasar images […]

Impact of baryonic feedback on HSC Y1 weak lensing non-Gaussian statistics

Kavli Affiliate: Jia Liu | First 5 Authors: Daniela Grandón, Gabriela A. Marques, Leander Thiele, Sihao Cheng, Masato Shirasaki | Summary: Baryonic feedback is a major systematic in weak lensing cosmology. Its most studied effect is the suppression of the lensing power spectrum, a second-order statistic, on small scales. Motivated by the growing interest in […]
