In a U.S. National Science Foundation-funded study published in Nature Astronomy, an international team of researchers has presented a new, detailed look inside the "central engine" of a lar...
Fe-K line probing of material around the AGN central engine with Suzaku
galaxies active — galaxies Seyfert — X-rays galaxies
2010/11/11
We systematically analyzed the high-quality Suzaku data of 88 Seyfert galax-ies, about 31% of which are Compton-thick AGNs. We obtained a clear relation between the absorption column density and the e...
Instabilities in the Gamma Ray Burst central engine. What makes the jet variable?
High Energy Astrophysical Phenomena (astro-ph.HE)
