WebAccounting for complex density gradients and temperature profiles is critical for reliably estimating the fundamental properties of Hii regions and galaxies. Diffuse ionized gas can raise metallicity estimates, flatten metallicity gradients, and introduce scatter in ionization parameter measurements. WebRecent Chandra X-ray observations of many galaxy clusters find evidence for hot metal-rich outflows preferentially aligned with the large-scale axes of X-ray cavities with typical outflow masses of around - . Here we …
WebActive galactic nuclei (AGN) are powered by the accretion of material onto a supermassive black hole (SMBH) and are among the most luminous objects in the Universe. However, the huge radiative power of most AGN cannot be seen directly, as the accretion is hidden behind gas and dust that absorb many of the characteristic observational signatures. WebActive galactic nuclei (AGN) and ultraluminous infrared galaxies (ULIRGs) represent two categories of galactic systems whose evolution has been modified by an interaction event. Galaxy–galaxy interactions are known to disrupt the stellar component of galactic disks and enhance the star formation rate.
WebExisting star-forming vs. active galactic nucleus (AGN) classification schemes using optical emission-line diagnostics mostly fail for low-metallicity and/or highly star-forming … WebOct 24, 2024 · AGN photoionization, the process by which the AGN’s ionizing photons strike nearby atoms or molecules and strip them of their electron (s), has traditionally been suspected of producing ionized ultraviolet and optical emission lines near AGNs. On the other hand, shock waves have also been shown to play a critical role in this process.
