Description

I will present the Hubble Constant controversy, that is, the different direct or indirect measurements of the Hubble Constant and how some are in significant tension. Then I'll present our current work on astrophysical bias in Type Ia Supernova distance measurements and explain how such effect could explain the aforementioned tension.
