A Suzaku Observation of MCG-2-58-22: Constraining the Geometry of the Circumnuclear Material
Galaxies: active – X-rays galaxies – Galaxies Individual
2011/8/24
We have analyzed a Suzaku long-look of the active galactic nucleus MCG-2-58-22, a type 1.5 Seyfert with very little X-ray absorption in the line of sight and prominent features arising from reflection...
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...

I review multiwavelength observations of material seen around different types of evolved massive stars (i.e. red supergiants, yellow hypergiants, luminous blue variables, B[e] supergiants, and Wolf-Ra...
A team of astronomers based in Europe has obtained a three-dimensional view of the innermost material released by a supernova – something never before seen. The researchers discovered a turbulent envi...
