3 Occur in Active Galactic Nuclei (AGN): fundamental phase in galaxy evolution Madau & Dickinson 2014: Why? SMBH growth connected to galaxy growth -> How? Feeding and feedback of SMBH needed to reproduce gal. lum. function Black: SFR Red: SMBH growth x 3,300 J. Silk:

5 Gemini NIFS survey of feeding and feedback in nearby active galaxies: Brazilian LLP2 29 AGN - with log(lx)>41.5 and closer than z=0.015 (Riffel+18) Ionised gas kinematics in local active galaxies using GMOS-IFU: local sample of 24 AGN (Ruschel- Dutra+18; poster by Gabriel Souza dos Santos); Follow up of MaNGA SDSS-IV AGN studies (Riffel+18, Wylezalek+17): presentation by Janaina Nascimento

7 HST F606W images of inner kpc (Simões Lopes+07, Malkan 98) : Dusty nuclear spirals in all earlytype AGN; But in only 25% of control sample; -> Nuclear spirals correlated with AGN: channels to feed the SMBH (Maciejewski 04, van de Ven & Fathi 10; Piñol-Ferrer+12; Hopkins+Quataert 10) active non-active active nonactive
8 Sa, LINER/Seyfert kpc x 1 kpc Nuclear spiral 0.6 =60 pc
9 Stellar kinematics from absorption spectra (ppxf, Cappellari & Emsellem2004) Gas kinematics from emission lines
10 Gas kinematics Stellar velocity field: rotation Stellar kinematics Gas velocity field: rotation + distortions correlated to spiral arms in structure map: blueshifts in the far side and redshifts in the near side -> inflow if gas in the plane Mass inflow rate: 0.4 M yr -1 ; similar case: NGC1667: 2.4 M yr -1 (Schnorr-Müller+17)
11 SO, Sy 2 FOV= 450 pc x 450 pc 0.1 =15 pc Gas kinematics: H2 Stellar kinematics: CO
12 Stellar velocity field: rotation H2 velocity field: rotation + inflows + compact outflow Warm (2000K) H2 mass 1400 M ; Far Warm H2: heated skin of cold gas; Cold H2 mass (Dale+05, Mazzalay +12) ~ M Near Warm H2 mass inflow rate 4 x 10-4 M yr -1 ; estimated cold: > 1 M yr -1
13 NGC1097 nuclear spiral: Fathi+06 NGC6951 nuclear spiral: Storchi-Bergmann+07 NGC4051 nuclear spiral: Riffel+08 NGC7582 inflow from nuclear ring: Riffel+09 M81 nuclear spiral: Schnorr Müller+11 Mrk1066 nuclear spiral + compact disk: Riffel+11 Mrk79 nuclear spiral + compact disk: Riffel+13 Mrk766 compact H2 disk: Shönell+14 NGC3081 nuclear bar: Schorr Müller+16 NGC1358 nuclear spiral: Schnorr Müller+18
14 Ionised gas HII: HII more concentrated near the nucleus and along ionization axis: HI rapidly absorbs ionizing photons HII masses: ( )x10 6 M ; surface density ΣHII= M pc -2 Warm molecular gas H2: H2: more uniform and extended: X-rays penetrate the galactic plane in all directions -> heat molecular gas H2 masses: (0.05-3)x10 3 M ; surface density ΣH2=(0.2-14)x10-3 M pc -2
15 Inflows in nuclear spirals, bars and disks, observed in H + and H2; capture of dwarf companion (Fischer+15); Inflow velocities: ~ km/s; Inflow rates: ~0.1 few M yr -1 : times the AGN accretion rate; Total H + masses in inner kpc ~ M Warm H2 masses: ~10 3 M ; in cold H2: estimated M (e.g. ALMA) Øco-evolution: SMBH at 10-3 M yr -1 and galaxy at 1 M yr -1
16
17 NLRG, Sy = 700 pc Extended [OIII] emission not aligned with radio jet (45deg)
18 High σ around the nucleus: 2 kinematic components: (1) Broad, perp. to radio jet -> outflow: lateral expansion? (1) Narrow, extended -> rotation Total gas mass: 4.1 ± 1.7 x 10 8 M Mass outflow rate: ~0.1 M yr -1 Outflow power: ~0.1% LAGN
19 [Fe II] flux [Fe II] σ Sab pec, Sy 2, 2 radio blobs 1 = 175 pc High σ perp. radio axis: double lines; also in two radio blobs Lower sigma elsewhere Gas counter rotating relative to the stars
20 Outflow Rotation + equatorial outflow Lateral expansion due to radio jet? Mass outflow rate:~ 0.4 M yr -1 HII mass: 1.3 ± 0.2 x 10 6 M Warm H2 mass: 471 ± 58 M rotation
21 HST [OIII] Sb, Seyfert pc x 500 pc 0.1 = 7 pc Das et al [FeII], J and H-band: bipolar (bicome) H2: 100 pc off-centered ring
22 [Fe II] and H 2 N Far side E [Fe II]: patchy outflow Velocities up to 800 km/s Mass outflow rate: 4± 1 M yr Outflow power: ~0.1% LAGN H2 ring: rotation+ expansion in the plane -200 km/s < v < +200 km/s
23 NGC4151: Storchi-Bergmann+10 hollow conical Mrk1066: Riffel+10 Mrk1157: Riffel+11 Mrk79: Riffel+13 Arp102B: Couto+13 NGC2110: Schnorr-Müller+14 NGC1386: Lena+15 NGC5548: Schönell+16 NGC1667: Schnorr-Müller+16
24 Outflows mapped via W80 (high. vel. wings): v=w80/1.3
25 ~60% have non-circular motions (mostly outflows) Mean outflow rate: ~0.3 M yr -1 (range: M yr -1 ) Mean outflow power: P~10 41 erg/s (range erg/s) Only 1/3 sample have P>1% LAGN-> meaning effective feedback on galaxy
26 Outflows with velocities: 200 (most) 800 (few) km s -1 and mass outflow rates of tenths to a few M yr -1 Geometry: (1) Unresolved compact (inner pc): need of better angular resolution (2) Extended perpendicularly to ionization/jet axis: lateral expansion of gas as jet progresses through it? (3) Resolved bi-polar (Fisher+13: ~ 1/3 of AGN) In all cases most extended emission does not originate in outflowing gas but in gas rotating in the galaxy disk ionized by the AGN Outflow power: <1% LAGN in 2/3 of the sample -> little effect on the galaxy On-going: study of farther and more luminous AGN (MaNGA, GMOS-IFU, NIFS)
