Changing look AGN
(LaMassa+2015)Optical type change (SDSS J0159+0033)
from Type 1 to Type 2
![Page 7: Miguel P´erez Torres on behalf of the CARS teammartescuantico.weebly.com/uploads/2/3/9/7/23970537/mrk...40 unobscured (Type 1) AGN from Hamburg/ESO survey with z < 0.06 Follow-up](https://reader034.fdocuments.net/reader034/viewer/2022050312/5f74422ae163c91a03255be2/html5/thumbnails/7.jpg)
Why do AGN change their typeObscuration by a cloud from the torusTidal Disruption Event (TDE)Change in accretion rate/flow
![Page 8: Miguel P´erez Torres on behalf of the CARS teammartescuantico.weebly.com/uploads/2/3/9/7/23970537/mrk...40 unobscured (Type 1) AGN from Hamburg/ESO survey with z < 0.06 Follow-up](https://reader034.fdocuments.net/reader034/viewer/2022050312/5f74422ae163c91a03255be2/html5/thumbnails/8.jpg)
Obscuration by a cloud from the torus⇒ Cloud event lasts hours to ∼month (e.g., NGC1356 - Maiolino+2010)
![Page 9: Miguel P´erez Torres on behalf of the CARS teammartescuantico.weebly.com/uploads/2/3/9/7/23970537/mrk...40 unobscured (Type 1) AGN from Hamburg/ESO survey with z < 0.06 Follow-up](https://reader034.fdocuments.net/reader034/viewer/2022050312/5f74422ae163c91a03255be2/html5/thumbnails/9.jpg)
Tidal Disruption Event (TDE)⇒ Bright flare with power-law decline (L ∝ t−5/3) decline
![Page 10: Miguel P´erez Torres on behalf of the CARS teammartescuantico.weebly.com/uploads/2/3/9/7/23970537/mrk...40 unobscured (Type 1) AGN from Hamburg/ESO survey with z < 0.06 Follow-up](https://reader034.fdocuments.net/reader034/viewer/2022050312/5f74422ae163c91a03255be2/html5/thumbnails/10.jpg)
Change in the accretion rate⇒ Long timescale (extrapolated from jetted X-ray binaries)

Motivation
(Di Matteo+2005, Nature)
Quasars regulate the growth and activity of BHs and their hostsGalaxy-galaxy collision → SF burst (+strong gas inflow to SMBH) →Quasar expels energy → (SF and BH growth) quenching

High-spatial radio observations of CARS galaxies
Imaging the neutral atomic gas of CARSVLA-H I maps PI: Perez-TorresVery deep H I images (MHI. 1.2× 109M�)Obtain H I maps at same angular resolution as CO maps ⇒ Total gascontent, H2/HI ratio, large scale inflow vs. outflow
Imaging the radio synchrotron emission of CARSMulti-frequency VLA continuum PI: Perez-Torres⇒ Trace compact SF and jet activity in the central ∼500 pc.

Mrk1018: The light curve in the past 15 yr
TDE very unlikely due to persistent activity over ∼30 yr(McElroy+PT+2016)

Mrk1018: X-ray spectra (Chanda + NuStar)
X-ray spectra consistent with no absorption⇒ Accretion disc luminosity is declining (Husemann+PT+2016)
![Page 24: Miguel P´erez Torres on behalf of the CARS teammartescuantico.weebly.com/uploads/2/3/9/7/23970537/mrk...40 unobscured (Type 1) AGN from Hamburg/ESO survey with z < 0.06 Follow-up](https://reader034.fdocuments.net/reader034/viewer/2022050312/5f74422ae163c91a03255be2/html5/thumbnails/24.jpg)
Mrk1018: Optical to X-ray SED
Peak luminosity shifts by a factor of ∼ 2 in wavelengthRoughly consistent with L ∝ T 4 relation⇒ Support for intrinsic changes in accretion

What is causing the change in accretion rate?
Ignition of an outflow? Binary SMBH?
