ZacharyWeaverHello! I am Zachary Weaver, a fifth-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?

Recent News:

  • I am currently writing up my next paper, tracking the radio-emitting knots of blazars down their jets. Look for it hitting the ArXiv soon!
  • I had a paper accepted in the Astrophysical Journal this summer, focused on our monitoring effort of BL Lacertae last fall. You can find the paper here. We used Fermi, NuSTAR, Swift, TESS, and WEBT data to obtain time resolution down to minutes!
  • Several of my collaborators have had recently accepted papers, such as this one one 3C 454.3 and this one on 3C 279.

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
