About
Christopher W. Morgan is an astrophysicist renowned for his pioneering work in gravitational lensing and accretion disk astrophysics. His research centers on using microlensing—the gravitational deflection of light by compact objects—to probe the inner regions of quasars, particularly the structure and size of their accretion disks. In his landmark 2013 study, "Time Delay and Accretion Disk Size Measurements in the Lensed Quasar SBS 0909+532 from Multiwavelength Microlensing Analysis" (38 citations), Morgan and his team analyzed three seasons of SDSS r-band photometry from the U.S. Naval Observatory and two seasons of g- and r-band data from the Liverpool Robotic Telescope. This work provided critical measurements of the time delay between lensed images and constrained the accretion disk size, offering direct evidence for the standard thin-disk model. By combining multiwavelength monitoring with sophisticated microlensing models, Morgan has advanced our understanding of quasar structure and the distribution of dark matter in lensing galaxies. His contributions have been instrumental in establishing microlensing as a powerful tool for extragalactic astronomy, inspiring a generation of researchers to explore the cosmos through gravitational lenses.
