Abstract

Hypervelocity stars are important for better understanding the nature of dark matter in the galaxy. By studying hypervelocity stars in the galaxy, we can gain a better understanding of the distribution of dark matter in the galaxy. However, finding hypervelocity stars in the Milky Way is difficult. My project utilized the Dark Energy Survey (DES) to develop a method for identifying hypervelocity stars in the DES database. To identify a hypervelocity star, I the clumping of the observation locations in the sky and compare the trend of the location over time. This method can be implemented in the future to search the DES database for new hypervelocity stars instead of just confirming the findings of other projects in this field.
