    [Abriged] Supermassive black holes (SMBH) lurk in the nuclei of most massive galaxies, perhaps in all of them. The tight observed scaling relations between SMBH masses and structural properties of their host spheroids likely indicate that the processes fostering the growth of both components are physically linked, despite the many orders of magnitude difference in their physical size.

    An active galactic nucleus (AGN) is a compact region at the center of a galaxy that has a much-higher-than-normal luminosity over at least some portion of the electromagnetic spectrum with characteristics indicating that the luminosity is not produced by stars.

    Their growth as active galactic nuclei (AGN) produces a significant fraction of the luminosity in the universe. Moreover, the masses of galactic bulges and SMBHs appear to correlated, which suggests the importance of the AGN in galaxy evolution (e.g., via AGN feedback). However, we face a basic limitation.

    Apr 06,  · What are Active Galactic Nuclei (AGN)? In some galaxies, known as "active galactic nuclei" (AGN), the nucleus (or central core) produces more radiation than the entire rest of the galaxy! Quasars are very distant AGN - the most distant quasars mark an epoch when the universe was less than a billion years old and a sixth of its current size.

    Jan 11,  · Models of active galaxies also include a region of cold gas and dust, thought to be in the shape of a giant donut with the black hole and accretion disk nestled in the donut's vermotideslyanatacharvajibepa.xyzinfo about one out of ten AGN, the black hole and accretion disk produce narrow beams of energetic particles and ejects them outward in opposite directions away from the disk.
