You can share your workshop contribution on this Zenodo web page.

There are no official proceedings, but if you wish to share your research, consider the Universe Special Issue "A Multimessenger View of Supermassive Black Holes and the Quasar Main Sequence", edited by Paola Marziani and Ascensión del Olmo. The topic greatly overlaps with that of the workshop, and as Paola mentioned there is a reasonable amount of publication fee waivers. Please, contact either Paola or Ascensión for more information.


In the last two decades, the unified models of active galactic nuclei (AGN) have been able to explain several of their observational properties. Whereas the simple orientation-based unification model works as a first-degree approximation, the reality is more complicated, and there is a host of different parameters at play. Statistical methods, aimed at simplifying multidimensional data, and in particular the so-called eigenvector 1 (EV1), have proven to be a useful tool in studying AGN grand unification. The position of a source on the EV1 is believed to be a combination of observational (mainly inclination) and physical properties, with the Eddington ratio acting as the main driver. However, different stages of AGN evolution can also appear as different classes of sources. Indeed, mounting evidence shows that the AGN life-cycle, that is, how AGN are born, how they grow, and how they interact with their closest environment, likely plays an essential role in this grand unification scenario. The main purpose of this workshop is to present the current status of the research on the life-cycle of active galactic nuclei, to discuss its future direction, and prepare for the advent of the new space- and ground-based observational facilities (e.g., JWST, Athena, ELT, Euclid).


We invite contributed talks and posters to be submitted for the workshop "Panchromatic view of the life-cycle of AGN". Our main topics are:

Narrow-line Seyfert 1 galaxies
Early-stage AGN
Intermittent activity
Duty cycle of AGN
Quasar main sequence
Multifrequency observations

We have reached the maximum number of participants, and the registration is closed.

in-person registration with ABSTRACT SUBMISSION

Registration form with abstract submission can be found here, and will remain open until 24.7.2022. Since one of the main goals of this workshop is to encourage discussion, which has proven to be challenging in hybrid/online meetings, all the talks will be given in-person.


The registration form will remain open until 26.8.2022 and can be found here. There is no registration fee. We can not provide financial support for any other expenses, such as, lunch, dinner, accommodation, or flights.

Please be informed that due to the continuously evolving situation of the pandemic, the COVID policy at ESAC might change in the coming months and more or less restrictions may apply during the workshop. We will be keeping you updated, if this would be the case.

As the Organising Committee of the workshop, we assume that all participants share our commitment to create a meeting environment that values diversity and inclusion and therefore is free from harassment. We want to promote a diverse environment with respectful and courteous behaviour and therefore we expect all participants to adhere to our Code of Conduct.

ONLINE participation

The workshop talks will be streamed online, and you can find the links below:


The online participants will be able to ask questions using the YouTube live chat.



ESAC is located some 30 km west of Madrid and it will thus be best to search for a hotel in the western parts of Madrid.

Please note that ESA does not offer hotel reservation services, nor has authorised any third party to do so on its behalf.

We will not block hotel rooms for the conference in any particular hotel, but a list of recommended hotels in this area together with useful links is posted below:

Other useful links to find budget hotels:


A shuttle bus service will be provided free of charge for transport between Madrid and ESAC, via Hotel Majadahonda (and same route back) for the three days of the meeting. In Madrid, the bus will pick you up (and drop you off) in front of the Hotel Exe Moncloa (C. Arcipreste de Hita, n. 10, 28015 Madrid), situated right next to the Moncloa bus and metro station.

The bus departs Madrid at the following times:

Wednesday 12:30
Thursday 08:00
Friday 08:30

and will reach Hotel Majadahonda in 15-25min. The bus will depart ESAC each day after the program has finished. On Friday, in case your flight leaves early, it will be possible to arrange transportation to Hotel Majadahonda / Madrid / Airport using smaller shuttles or shared taxis. These can be organised during the workshop, so there is no need to let us know of it in advance.


If you will be arriving late and can't use the workshop bus, or will be arriving by car, you can follow these instructions to reach ESAC and find the workshop room.

Reaching ESAC using public transportation

There are no public buses to ESAC after ~8am, so if you don't make it to the workshop bus, the best option is to take train C10 to Majadahonda (takes about an hour from the airport), and take a taxi to ESAC (~15mins). Cabify and FreeNow work the best in Spain, and the taxi trip should be 15-20€. If you arrive to Terminal 4, you can catch the C10 directly from there. If you arrive to Terminal 1/2/3, you can take the metro to Nuevos Ministerios, and change to C10 there. Upon arriving to ESAC you need to collect your badge from the gate security (building  "A" in the map below), and they'll also check your ID.

Reaching ESAC by car

1) You will arrive to ESAC from the direction of M-503. 
2) When you reach ESAC there is a roundabout, that you can exit to park your car outside the gate (the parking spots are situated right above the "A" in the map.)
3) Next you need to enter the gate security building ("A") to show your ID and get your badge. You can ask them where to park the car (i.e. outside or inside the fence.)

Entering ESAC

Once you have your badge, you can enter ESAC. The workshop is organised in building B (also "B" in the map) that you can enter through the main doors without special clearance. The workshop room is the first one on the left (B003/B005) when you enter the lobby. The ESAC canteen, where you can get lunch, is in building "C".



The workshop will be held in person in ESAC, Villanueva de la Cañada, Madrid, Spain. We will follow closely the development of the pandemic and travelling restrictions in the next months. Changes and updates will be announced on this page and via email to the registered participants.
