Bookmark or Share- NASA’s IXPE Fires Up Astronomers With New Blazar FindingsJul 18, 2023. Article. An international team of astrophysicists, using new data from NASA’s Imaging X-ray Polarimetry Explorer (IXPE), published findings about the blazar called Markarian 421 – which offered some surprising results. The universe is full of powerful supermassive black holes that create powerful jets of high-energy particles ...
- NASA's Fermi Discovers the Most Extreme Blazars Yet - NASANASA’s Fermi Gamma-ray Space Telescope has identified the farthest gamma-ray blazars, a type of galaxy whose intense emissions are powered by supersized black holes. Light from the most distant object began its journey to us when the universe was 1.4 billion years old, or nearly 10 percent of its present age.
- NASA’s IXPE Helps Solve Black Hole Jet Mystery - NASANov 23, 2022. Article. Some of the brightest objects in the sky are called blazars. They consist of a supermassive black hole feeding off material swirling around it in a disk, which can create two powerful jets perpendicular to the disk on each side. A blazar is especially bright because one of its powerful jets of high-speed particles points ...
- Blazar - WikipediaBlazars are powerful sources of emission across the electromagnetic spectrum and are observed to be sources of high-energy gamma ray photons. Blazars are highly variable sources, often undergoing rapid and dramatic fluctuations in brightness on short timescales (hours to days).
- What exactly are blazars and quasars? How are they different?A blazar and quasar are essentially the same thing, with the former just tilted differently to our line of site. Both are the active centers of galaxies, feeding off nearby material. Astronomy ...
