Searching ETI: possibility of follow-up observations of microlensing events with the radio telescopes

Sohrab Rahvar

Physics Department Sharif University of Technology

 

Abstract: In this talk, I will give a brief review of gravitational microlensing and history of detecting exoplanets with the microlensing method. Then, we discuss the theoretical basis of caustic crossing in the binary lenses. Assuming the extraterrestrial intelligence (ETI) uses the same radio stations on his/her planet as we have on the Earth, we study the possibility of follow-up microlensing observation as the natural amplifiers to magnify the radio signals from the ETIs. We investigate wave optics effects in the magnification factor for the radio waves. Finally, we will discuss the feasibility of this observation with the present radio telescope surveys.

NOTE: Professor Sohrab Rahvar is invited by  the research center of “The Search for Extraterrestrial Intelligence (SETI) At UC Berkeley” for the seminar.
