Seminar 
Title: Black Hole Mimickers in Quadratic Gravity 
Speaker: Dr. Ufuk Aydemir (IHEP, CAS) 
Time: 2:00 PM, Sep. 5th (Thursday), 2019 
Place: R319, Theoretical Physics Division 

Abstract:
In this talk, the speaker will focus on ultracompact horizonless objects arising as a class of solutions in quadratic gravity, recently dubbed as 2-2 holes. He will review features of these objects and discuss them in the context of dark matter in similarity to primordial black holes.
