Title: Satellites in MW-like Hosts: Accretion history and Pairs

Abstract:
Using cosmological dark matter simulations we study in detail the accretion history of subhalos 
in MW-like hosts.
We identify subhalos accreted through filaments, and we found they have longer lifetimes when 
compared with all subhalos at fixed masses. 

In addition, following Gonzalez et al. 2013 results, we explore the orbits of bound subhalos 
pairs, their stability, life times and comparison with dynamical friction times. Results indicate if 
the Magellanic Clouds are a bound pair, then there is a 90% chance they where accreted in the 
last 3.8Gyr and 50% in the last 1.6Gyr, supporting a first infall scenario for the MCs.
