BUILDING BLOCKS FOR BLAZARS

 

Abstract: We begin by building up the concept of scale in the universe through the lens of light travel time for the purpose of defining blazar size and distance between galaxies. Then, we will explore the structure and characteristics of active galaxies before diving into the physics of blazar jets, how it is studied and some key findings about the importance of particle acceleration and the limitations of current multiwavelength observations. We will then examine a suggested direction for the field of astrophysics and some thoughts on programmatic balance among the suite of missions NASA will solicit over the coming decades.


Bio: Dr. Tiffany Lewis received her PhD in Physics from George Mason University, while studying high-energy astrophysical theory and active galactic nuclei. She spent time in Israel as a Zuckerman Postdoctoral Fellow between Haifa and Tel Aviv Universities. Dr. Lewis is currently a NASA Postdoctoral Program Fellow at Goddard Space Flight Center, where she has been recognized for her leadership and advocacy in high-energy and multimessenger astrophysics through the Snowmass Community Planning Process.
