Event Details & Abstract: 

Tentative Topic: The recent second data release from the ESA satellite Gaia gives us the opportunity to search for extremely high velocity stars in the largest stellar catalogue ever produced. In this talk I will focus on 
the high velocity tail of the distribution of total velocities, to search for objects whose velocity exceeds the escape speed from the Milky Way: hypervelocity stars and hyper-runaway stars.
