The Chandra detection of two luminous (L = 1.5 × 10 and 3.8 × 10 erg cm s ), unresolved nuclei in Mrk 463 indicates that this galaxy hosts a binary active galactic nucleus (AGN), with a projected separation of ≃3.8 kpc (3.83 ± 0.01 arcsec).

Mar 25, 2016 · Binary active galactic nuclei (AGNs) provide clues to how gas-rich mergers trigger and fuel AGNs and how supermassive black hole (SMBH) pairs evolve in a gas-rich environment. While significant...

May 20, 2016 · Binary active galactic nuclei (AGNs) provide clues to how gas-rich mergers trigger and fuel AGNs and how supermassive black hole (SMBH) pairs evolve in a gas-rich environment. While significant effort has been invested in their identification, the detailed properties of binary AGNs and their host galaxies are still poorly constrained. In a companion paper, we examined the nature of ionizing ...

Jan 10, 2025 · Iron Lines in X-ray have been detected from a well-known binary black hole system in the radio galaxy 4C+37.11 750 million light years away from the Earth, making way for study of the properties of the system.

May 1, 2008 · The Chandra detection of two luminous (L2–10 keV= 1.5 × 1043 and 3.8 × 1042 erg cm−2 s−1), unresolved nuclei in Mrk 463 indicates that this galaxy hosts a binary active galactic nucleus...

We present Chandra and XMM-Newton observations of the composite starforming/Seyfert galaxy IRAS20051-1117. The X-ray imaging and spectral properties reveal the presence of an active nucleus. The Chandra image shows a strong nuclear point source (L(2 − …

Oct 27, 2014 · A new study of 209 galaxies in the early universe with X-ray bright supermassive black holes reveals that more modest active galactic nuclei (AGN) tend to peak later in cosmic history, and that obscured and unobscured AGN evolve in similar ways.

Mar 19, 2008 · The Chandra detection of two luminous (L 2–10 keV = 1.5 × 10 43 and 3.8 × 10 42 erg cm −2 s −1), unresolved nuclei in Mrk 463 indicates that this galaxy hosts a binary active galactic nucleus (AGN), with a projected separation of ≃3.8 kpc (3.83 ± 0.01 arcsec).

Dec 20, 2012 · We critically examine and confirm the binary-AGN scenario for two of the four targets, by combining high angular resolution X-ray imaging spectroscopy with Chandra ACIS-S, better nuclear...
