Hello! I am Zachary Weaver, a third-year graduate student in the Boston University Department of Astronomy and Institute for Astrophysical Research. I study the most interesting objects in the entire Universe: Blazars! Blazars are the most luminous objects in the Universe, emitting light at all wavelengths, from radio waves to gamma rays. In one of the ironies of the Universe, these extremely bright objects are powered by a near-invisible central engine – a supermassive black hole containing the mass of hundreds of millions of Suns, whose gravity is so strong that not even light can escape. The main question I am trying to answer is how this irony occurs in the first place: How can black holes power the brightest objects in the Universe?
- I will be attending the 235th AAS Meeting in Honolulu, Hawaii, and presenting my work on the kinematics of parsec-scale jets of gamma-ray blazars at 43 GHz. If you will be there, swing by!
- I also will be attending the TESS Ninja, Part 3 Workshop, “Expanding the Science of TESS,” in February at the University of Sydney. We hope to use the Transiting Exoplanet Survey Satellite (TESS) to obtain high-time resolution observations of blazar variability.
- I had a paper, The June 2016 Optical and Gamma-Ray Outburst and Optical Micro-Variability of the Blazar 3C454.3, published in April 2019! See my Publications page for more details.
Every atom in your body came from a star that exploded. And, the atoms in your left hand probably came from a different star than your right hand. It really is the most poetic thing I know about physics: You are all stardust. – Lawrence Krauss
