About the Collaboration
The EREBUS Collaboration has been a long journey in the making, beginning with our first JWST workshop on Santa Barbara Street in February 2017, and continuing through the memorable Ringberg Black Hole meeting in March 2020. This collaboration was officially formed in August 2022 by merging teams from two JWST Cycle 1 medium-size programs: Quasar Frontier (GO 1764) and ASPIRE (GO 2078).
We got our first JWST data in August 2022 and initiated five dedicated working groups, each focused on a specific research area, with the five PIs of the two JWST programs serving as the steering committee. These working groups coordinate discussions on projects and papers. Each steering committee member has committed to overseeing the activities of one of these five working groups:
- Black Hole Mass and AGN Physics (Coordinator: Eduardo Bañados)
- Galaxies and Ancillary Science (Coordinator: Xiaohui Fan)
- Quasar Environment and Large-Scale Structure (Coordinator: Feige Wang)
- Quasar Host Galaxies (Coordinator: Jinyi Yang)
- Reionization and the Intergalactic Medium (Coordinator: Joseph Hennawi)
We have made many exciting scientific discoveries and have had many more JWST programs, as well as other multi-wavelength follow-up programs, approved. Our collaboration continues to grow and has now attracted more than 100 scientists, including a significant fraction of students and postdocs. The working groups and their research topics also continue to evolve over time. In preparation for the upcoming large-scale surveys with Euclid, Roman, and Rubin, the collaboration is positioning itself to enter a new stage of cosmic discoveries.
EREBUS Collaboration Meetings
2026 EREBUS collaboration meeting Upcoming
Date: 3–7 August 2026
Place: Ann Arbor, Michigan (United States)
Main topics:
With the start of Euclid and Rubin’s science operations and the forthcoming Roman launch, we envision dedicated sessions focused on how our collaboration can continue to lead high-redshift quasar/AGN and galaxy studies in the Euclid + LSST + Roman + JWST era. In addition, we will hold talks on ongoing and planned JWST-related projects and discussions in preparation for JWST Cycle 6 proposals.

2025 EREBUS collaboration meeting
Date: 18–20 June 2025
Place: Strada Maggiore 34, 40125, Bologna (Italy)
Main topics:
The large international collaborations EREBUS and COSMOS-3D, together with astronomers generally interested in the high-redshift Universe will meet in Bologna to review findings from observations collected in recent years and brainstorm new science ideas in preparation for JWST Cycle 5. To facilitate focused interactions on projects related to high redshift quasars, their host galaxies, and their surrounding environments, the meeting will be open to selected guests only.

2023 EREBUS collaboration meeting
Date: 3–6 October 2023
Place: BIOSPHERE 2, Tucson, Arizona (United States)
Main topics:
EREBUS is an international collaboration of astronomers broadly interested in high-redshift quasars, their host galaxies, and their surrounding environments. In preparation for JWST Cycle 3, we would like to have everyone together in sunny Arizona to review what we have learned from our initial datasets and brainstorm yet more science ideas.
Note: This is the first EREBUS collaboration meeting after they got JWST data in the Summer of 2022.

2020 Winter Ringberg workshop
Date: October 2020
Place: Ringberg Castle (Germany)
Main topics:
Our goal is to bring together a selected group of observational and theoretical experts in the field of the formation and evolution of the first massive galaxies and black holes in the Universe.
This timely workshop gathers the experts in the field to discuss the best strategies and prepare strong JWST Cycle 2 proposals.
2020 Spring Ringberg workshop: Black holes and galaxies at the edge of the Universe
Date: 1–6 March 2020
Place: Ringberg Castle (Germany)
Main topics:
Our goal is to bring together a selected group of observational and theoretical experts in the field of the formation and evolution of the first massive galaxies and black holes in the Universe.
This timely workshop gathers the experts in the field to discuss the best strategies and prepare strong JWST Cycle 1 proposals.
Note: The original JWST Cycle 1 call for proposal was delayed due to pandemic.
2017 JWST ERS proposal Planning workshop
Date: February 2017
Place: Pasadena (United States)
Main topics:
Our goal is to bring together a selected group of observational and theoretical experts in the field of the formation and evolution of the first massive galaxies and black holes in the Universe.
This timely workshop gathers the experts in the field to discuss the best strategies and prepare strong JWST ERS proposals.
Note: The original JWST ERS call for proposal was delayed.
