Chaotic accretion can (still) explain early supermassive black hole growth
Kastytis Zubovas, Matas Tartėnas
The origin of supermassive black holes (SMBHs) is still debated, with hypotheses ranging from massive seeds to super-Eddington growth to chaotic accretion. Recent discoveries of ve…
Low-power jet-ISM coupling and disk-plane perturbations in the edge-on Seyfert galaxy NGC 4388
M. Ceci, G. Venturi, C. Marconcini +26
Active galactic nuclei (AGN) may regulate galaxy evolution through radiatively driven winds and collimated jets, but their relative impact and coupling to the interstellar medium (…
MIRACLE III. JWST/MIRI expose the hidden role of the AGN outflow in NGC 1068
C. Marconcini, A. Marconi, M. Ceci +27
We present new JWST IFS observations of the active galaxy NGC 1068, combining Mid-IR and optical IFS data from MIRI and MUSE to characterize the multi-phase circumnuclear gas prope…
Simple relations from complex outflows: How the relation emerges in a multi-phase environment
Matas Tartėnas, Kastytis Zubovas, Eimantas Skuodas
The tight empirical relation between the mass of a SMBH) and the velocity dispersion of the host galaxy bulge is often interpreted as the result of self-regulation by AGN fee…
Active galactic nucleus outflows accelerate when they escape the bulge
Kastytis Zubovas, Matas Tartėnas
Large-scale outflows driven by AGNs are an important element of galaxy evolution. Detailed analysis of their properties allows us to probe the activity history of the galactic nucl…
The complex effect of gas cooling and turbulence on AGN-driven outflow properties
K. Zubovas, M. Tartėnas, M. A. Bourne
(abridged) Accretion onto supermassive black holes (SMBHs) at close to the Eddington rate can influence the host galaxy via powerful winds. Theoretical models of such winds can exp…
Slow and steady does the trick: Slow outflows enhance the fragmentation of molecular clouds
Martynas Laužikas, Kastytis Zubovas
Most massive galaxies host a supermassive black hole at their centre. Matter accretion creates an active galactic nucleus (AGN), forming a relativistic particle wind. The wind heat…
MUSE view of PDS 456: kpc-scale wind, extended ionized gas and close environment
A. Travascio, E. Piconcelli, M. Bischetti +23
PDS 456 is the most luminous RQQ at z<0.3 and can be regarded as a local counterpart of the powerful QSOs shining at Cosmic Noon. It hosts a strong nuclear X-ray ultra-fast outflow…
Life after AGN switchoff: evolution and properties of fossil galactic outflows
Kastytis Zubovas, Gediminas Maskeliūnas
Galaxy-wide outflows driven by active galactic nuclei (AGN) are an important ingredient in galaxy evolution. Analytical calculations suggest that such outflows have significant ine…
The fraction and kinematics of broad absorption line quasars across cosmic time
Manuela Bischetti, Fabrizio Fiore, Chiara Feruglio +17
Luminous quasars are powerful targets to investigate the role of feedback from supermassive black-holes (BHs) in regulating the growth phases of BHs themselves and of their host ga…
Improving Black Hole Accretion Treatment in Hydrodynamical Simulations
Matas Tartėnas, Kastytis Zubovas
The large galactic scales are connected to the many orders of magnitude smaller supermassive black hole (SMBH) scales by an episodic cycle of feeding and feedback. Active galactic…
Determining AGN luminosity histories using present-day outflow properties: a neural-network based approach
Kastytis Zubovas, Jonas Bialopetravičius, Monika Kazlauskaitė
Large-scale outflows driven by active galactic nuclei (AGN) can have a profound influence on their host galaxies. The outflow properties themselves depend sensitively on the histor…
High-redshift SMBHs can grow from stellar-mass seeds via chaotic accretion
Kastytis Zubovas, Andrew R. King
Extremely massive black holes, with masses , have been observed at ever higher redshifts. These results create ever tighter constraints on the formation…
Intermittent AGN episodes drive outflows with a large spread of observable loading factors
Kastytis Zubovas, Emanuele Nardini
The properties of large-scale galactic outflows, such as their kinetic energy and momentum rates, correlate with the luminosity of the active galactic nucleus (AGN). This is well e…
The case for the fundamental - relation
Christopher Marsden, Francesco Shankar, Michele Ginolfi +1
Strong scaling relations between host galaxy properties (such as stellar mass, bulge mass, luminosity, effective radius etc) and their nuclear supermassive black hole's mass point…
Evolution of dwarf galaxy observable parameters
Eimantas Ledinauskas, Kastytis Zubovas
We present a semi-analytic model of isolated dwarf galaxy evolution and use it to study the build-up of observed correlations between dwarf galaxy properties. We analyse the evolut…
Feeding of active galactic nuclei by dynamical perturbations
M. Tartėnas, K. Zubovas
There possibly was an AGN episode in the Galactic Centre about 6 Myr ago, powerful enough to produce the Fermi bubbles. We present numerical simulations of a possible scenario givi…
Slow and fat: low-spin SMBHs are more massive
Kastytis Zubovas, Andrew R. King
Active galactic nuclei (AGN) probably control the growth of their host galaxies via feedback in the form of wide-angle wind-driven outflows. These establish the observed correlatio…
The relation between supermassive black holes and their host galaxies
K. Zubovas, A. R. King
Supermassive black holes (SMBHs) are found in the centres of most galaxies. Their masses, and hence their gravitational potentials, are negligible compared with those of the host g…
Warm absorbers: supermassive black hole feeding, and Compton-thick AGN
Kastytis Zubovas, Andrew King
Warm absorbers are found in many AGN and consist of clouds moving at moderate radial velocities, showing complex ionization structures and having moderate to large column densities…
Tidal disruption events can power the observed AGN in dwarf galaxies
Kastytis Zubovas
In recent years, numerous active galactic nuclei have been discovered in ever smaller galaxies, questioning the paradigm that dwarf galaxies do not harbour central massive black ho…
AGN must be very efficient at powering outflows
Kastytis Zubovas
Galaxy evolution is affected by competing feedback processes. Stellar feedback dominates in low-mass galaxies, while AGN feedback predominantly affects massive ones. Recent observa…
Multi-phase outflows as probes of AGN accretion history
Emanuele Nardini, Kastytis Zubovas
Powerful outflows with a broad range of properties (such as velocity, ionization, radial scale and mass loss rate) represent a key feature of active galactic nuclei (AGN), even mor…
Sgr A envelope explosion and the young stars in the centre of the Milky Way
