IAP: Gravitational Mirages (Paul Schechter, MKI)

Tuesday January 13, 2015 2:30 pm
Marlar Lounge (37-252)

According to Einstein’s theory, gravity produces what is, in effect, an index of refraction.¬† Light passing in the vicinity of an astronomical object will be delayed, deflected and distorted by the variations in this index of refraction, in a manner exactly analogous to terrestrial mirages. ¬†Such cosmic mirages are a major tool for the study of dark matter in galaxies and clusters of galaxies.

No enrollment limit, no advance sign up.
