TORUS 2022 Workshop
Smoke and Mirrors
Leiden 13-15 December


In the last few years the "central parsec" community for AGN studies has seen a fast development thanks to observations with infrared and sub-millimeter interferometers like ALMA, GRAVITY, and MATISSE, that can achieve parsec-scale resolution in nearby AGNs. These observations have stimulated the further developments of more complete "Torus" models. In this workshop we would like to share the latest developments in the field from both multi-wavelength observations and theoretical works. We also anticipate the opportunities that new instruments will bring in the near future. The topics we intend to focus on are:

  • Imaging and spectroscopy of AGN tori at infrared,
  • (Sub-)mm observations,
  • Future X-ray imaging and spectroscopy,
  • Polarimetry,
  • Reverberation and time variability, and
  • The physics of accretion disks and winds.

The Torus Workshops are organized roughly every three years to share most recent advancements concerning the physics of the centers of Active Galactic Nuclei. The last torus workshop, Torus2018, was in Puerto Varas Chile. This year the torus workshop will take place in Leiden, Netherlands on 13-15 December. We expect to accommodate about 70 in-person participants, limited to active researchers in the field. You can register your interest, and submit an abstract for a talk or poster Here

Covid Policy

Dutch Government and Leiden University policies do not require masking or distancing at meetings, and we shall follow these policies. If circumstances change, and the Government changes its policy, we will follow them. However we encourage participants to wear masks where the density is high.

Code of Conduct

Participants in the TORUS2022 workshop must conduct themselves professionally during activities connected with the workshop, and treat each other with respect. By taking part in the workshop, the participants agree to follow a code of conduct modelled on that of the European Astronomical Society, which is detailed here: Code


We have reserved a set of rooms at two Leiden hotels which offer discounts to University events:
  • Hotel IBIS -- Stationsplein 240-242 -- 2312 AR Leiden Netherlands. You can request a room by sending an email to and mention the booking code TORUS2022
  • Hotel Golden Tulip/Tulip Inn. You can register Here. Specify the blockcode TORUS2022
    If you have problems with the site, as some have, contact the hotel directly: +31714083500/

There are many other hotels in Leiden near the Venue that you can try, but we have not made special reservations or arranged discounts. Some are listed below and they have attractive prices. The conference organizers take no responsibility with regard to the availability, quality, price, or management of these hotels:
