A5 2 Survivability of Andromeda Evolving into a Blazar

Abstract

We consider the case that Andromeda evolves into a blazar, an active galaxy with a powerful jet pointing in the direction of the observer. We find that this scenario would pose little threat to life as we know it at the current distance of Andromeda when using lower bounds to calculate the received flux (5.71 x 10^-5 erg s^-1 cm^-2) and fluence (14.8 erg cm^-2) of the jet. In the case of upper bounds, there is also little threat unless a flare were to last approximately ten days.
