The Prevalence of Gas Outflows in Type 2 AGNs
TLDR
In this article, a detailed analysis on gas kinematics as manifested by the velocity dispersion and shift of the [O III] {\lambda}5007 emission line, using a large sample of ~39,000 type 2 AGNs at z < 0.3.Abstract:
To constrain the nature and fraction of the ionized gas outflows in AGNs, we perform a detailed analysis on gas kinematics as manifested by the velocity dispersion and shift of the [O III] {\lambda}5007 emission line, using a large sample of ~39,000 type 2 AGNs at z<0.3. First, we confirm a broad correlation between [O III] and stellar velocity dispersions, indicating that the bulge gravitational potential plays a main role in determining the [O III] kinematics. However, [O III] velocity dispersion is on average larger than stellar velocity dispersion by a factor of 1.3-1.4 for AGNs with double Gaussian [O III], suggesting that the non-gravitational component, i.e., outflows, is almost comparable to the gravitational component. Second, the increase of the [O III] velocity dispersion (after normalized by stellar velocity dispersion) with both AGN luminosity and Eddington ratio suggests that non-gravitational kinematics are clearly linked to AGN accretion. The distribution in the [O III] velocity - velocity dispersion diagram dramatically expands toward large values with increasing AGN luminosity, implying that the launching velocity of gas outflows increases with AGN luminosity. Third, the majority of luminous AGNs presents the non-gravitational kinematics in the [O III] profile. These results suggest that ionized gas outflows are prevalent among type 2 AGNs. On the other hand, we find no strong trend of the [O III] kinematics with radio luminosity, once we remove the effect of the bulge gravitational potential, indicating that ionized gas outflows are not directly related to radio activity for the majority of type 2 AGNs.read more

Star formation is boosted (and quenched) from the inside-out: radial star formation profiles from MaNGA

TL;DR: In this paper, the authors investigated the SFR profiles of 864 galaxies as a function of their position relative to the global star forming main sequence (Delta SFR), and found that for quiescent/passive galaxies that lie at least a factor of 10 below the global main sequence, there is an analogous deficit of star formation throughout the galaxy with the lowest values of Delta Sigma_SFR in the central 3 kpc.

Classification parameters for the emission-line spectra of extragalactic objects
TL;DR: In this paper, the merits of various emission-line intensity ratios for classifying the spectra of extragalactic objects were investigated and it was shown empirically that several combinations of easily-measured lines can be used to separate objects into one of four categories according to the principal excitation mechanism: normal H II regions, planetary nebulae, objects photoionized by a power-law continuum, and objects excited by shock-wave heating.

Energy input from quasars regulates the growth and activity of black holes and their host galaxies
TL;DR: Simulations that simultaneously follow star formation and the growth of black holes during galaxy–galaxy collisions find that, in addition to generating a burst of star formation, a merger leads to strong inflows that feed gas to the supermassive black hole and thereby power the quasar.
