NGC 7469 is a well known Luminous IR Galaxy, with circumnuclear star formation ring ($\sim 830$ pc radius) surrounding Seyfert 1 AGN. Nuclear unresolved winds were previously detected in X-rays and UV, as an extended biconical outflow coronal lines. We search for outflows by measuring the kinematics of $\mathrm{H\beta}$ [O III] $\lambda 5007$ optical emission lines, data VLT/MUSE integral field spectrograph. find evidence two kinematic regimes: one slower regime extending across most --...
Abstract Using Sloan Digital Sky Survey (SDSS) spectra, we applied an automatic method to search for outflows (OFs) in three large samples of narrow-line active galactic nuclei (AGN) at low redshifts ( z < 0.4), separated into spectral activity classes: radio-loud galaxies (RGs), 15,793; radio-quiet Seyfert 2 AGN (Sy2), 18,585; and LINERs, 25,656. In general, the probability detecting OF decreases along sequence Sy1→Sy2→LINER/RG independently class, wind velocity, traced by W 80,...

This paper reports on NOEMA observations addressed to constrain spatial scale CO emission in outflow. molecular outflowing gas resolved five components tracing approaching and receding gas, all located at distance 2-3~kpc West East side active nucleus. high velocity (up v_out=~1900 km/s) not coincident with rotation pattern host galaxy disk. estimated mass rate...
We explore the effects of tidal interactions on star formation (SF) by analysing a sample CALIFA survey galaxies. The consists tidally and non-tidally perturbed galaxies, paired at closest stellar mass densities for same galaxy type between subsamples. They are then compared, both resolved Star Formation Main Sequence (SFMS) plane in annular property profiles. Star-forming regions galaxies exhibit flatter SFMS slopes compared to star-forming Despite that profiles show as being mostly older,...
ABSTRACT The narrow-line Seyfert 1 galaxy IRAS 17020+4544 is one of the few sources where both an X-ray ultrafast outflow and a molecular were observed to be consistent with energy conservation. However, less massive has much more modest active galactic nucleus (AGN) luminosity than other examples. Using recent CO(1–0) observations NOrthern Extended Millimeter Array, we characterized gas content host for first time. We found that distributed into apparent central disc 1.1 × 109 M⊙, northern...

Using these adopted considering sensitivity grating device, we establish thresholds reliability that allow us to select reliable...

The bar is oval-shaped with semi-major axis length 3.23\arcsec\($\sim$2.09~kpc), almost flat light distribution along it. bulge round (ellipticity=0.21) an effective radius 1.62\arcsec\ ($\sim$1.05~kpc) Sersic index 0.99, parameters typical...
The optical spectra of 3,896 Seyfert~1 (Sy1) galaxies detected with WISE at z < 0.4 were analyzed for evidence outflows. In 37% the Sy1s outflows appear as broad, blue-shifted, [OIII]5007, a mean maximum velocity V_max ~1014 km/s$, consistent AGN winds. For each Sy1 we deduced that black hole (BH) mass, bolometric luminosity, Eddington ratio and power-law index continuum, which compared star formation rate (SFR) host morphology. Having separated our sample in two spectroscopic subgroups,...
In accordance with the AGN Unified Model, observed polarization can be related to orientation of line sight respect torus. X-ray emission arises from central region and carries imprints obscuring material. We aim test a unified scheme based on optical using absorption. Using XMM-Newton data 19, optically polarized Seyfert 1 sources, we develop systematic analysis by fitting baseline model presence neutral or ionized (warm) find that 100% polar-polarized sources show absorption, 70% favoring...

In general, the probability detecting OF decreases along sequence Sy1->Sy2->LINER/RG and, independently class, wind velocity, traced by W80, increases with luminosity. Moreover W80 is systematically higher RG or any other class when detected...
Galaxy evolution is generally affected by tidal interactions. Firstly, in this series, we reported several effects which suggest that interactions contribute to regulating star formation (SF). To confirm so, now compare stellar mass assembly histories and SF look-back time annular profiles between CALIFA survey tidally non-tidally perturbed galaxies. We pair their respective star-forming regions at the closest surface densities reduce influence of mass. The show statistically significant...

Abstract Using WISE data, we calibrated the W2-W3 colors in terms of star formation rates (SFRs) and applied this calibration to a sample 1285 QSOs with highest flux quality, covering range redshift from z ˜ 0.3 3.8. According our calibration, SFR increases continuously, reaching value at 3.8 about 3 times higher on average than lower redshift. This increase is accompanied by an BH mass factor 100 gradual mean Eddington ratio 0.1 up 1.5 – 2.0, above which stays constant, despite significant...
