Save the Date! AGN on the Beach II: A multi-scale view of jetted AGN. 21–25 September 2026, Diani, Kenya

***First Announcement***
Dear Colleagues,
We are excited to announce the planned meeting "AGN on the Beach II: A multi-scale view of jetted AGN", to be held 21–25 September 2026 in Diani, Kenya. We would like to ask you to spread the information to all those who might be interested.
This workshop will bring together experts in observations and simulations to advance our understanding of how relativistic jets and compact radio outflows from active galactic nuclei (AGN) influence their host galaxies. Despite major progress in high-resolution radio/mm facilities and hydrodynamical modelling, key questions remain about the physics that drives jet launching, the factors shaping radio morphology across scales, and the true impact of low-luminosity or small-scale jets on the interstellar medium and galaxy evolution. By integrating multi-scale perspectives, from black hole accretion processes to galaxy-wide feedback, this meeting aims to establish a coherent framework and define priorities for future multi-wavelength campaigns and theoretical efforts.
The Scientific Organising Committee is composed of:
Ann Njeri (chair) - Newcastle University

AGN on the Beach II:A multi-scale view of jetted AGN
21-25 September 2026, Diani, Kenya.
Scientific Rationale:
While relativistic jets are well-established agents of feedback in active galactic nuclei (AGN), compact radio outflows (jets or winds) are also thought to play a key role in driving galaxy evolution. However, their exact impact remains uncertain and is the subject of ongoing discussion. Recent observational progresses (e.g. high-resolution radio and mm interferometry, IFU spectroscopy, sensitive low-frequency imaging) and advances in hydrodynamical simulations have shown that even low-power or small-scale jets on (sub-)kpc scales can strongly perturb the surrounding interstellar medium (ISM), driving shocks and turbulence, and altering the star formation locally. Nevertheless, we still lack a coherent, multi-scale picture linking (i) the physics of SMBH accretion and jet launching at sub-parsec scales, (ii) the resulting radio morphologies on pc–kpc scales, and (iii) the net impact on galaxy evolution across environments and cosmic time.
This workshop will concentrate on the critical open questions in accretion vs ejection mechanisms highlighted recently by observational and theoretical studies: what primarily sets radio morphology (central engine vs environment vs age); whether the classical radio-loud/radio-quiet dichotomy maps to distinct physical modes or a continuum; how transitions between radiatively efficient and inefficient accretion manifest observationally; and what fraction of low-luminosity/compact radio sources actually host jets energetic enough to affect their hosts. By bringing together observers working with latest-generation radio and mm facilities (e.g. VLBI, e-MERLIN, MeerKAT, LOFAR, JVLA, ALMA, MUSE, JWST, etc.) and simulators modelling jet–ISM coupling, this meeting aims to convert recent fragmented results into a clear roadmap for future multi-wavelength observational campaigns and theoretical benchmarks. In particular, in this meeting we aim to address the following scientific topics:
What are the main factors that determine the morphologies of radio jets?
How do we differentiate between outflows driven by accretion disc winds and small-scale jets?
How do jets (or feedback in general) couple on different scales and what impact does this have on galaxy evolution/the environment?
What is the nature of the low-luminosity/compact radio-AGN (P₁.₄ < 10²⁴ W Hz⁻¹)? How do they interact with the surrounding environment? Can they provide feedback?
Meeting format
The workshop will take place in the wonderful location of Diani, located about 50km South of Mombasa (Kenya). We plan four full days and one half-day of scientific presentations and discussions. We aim to alternate some long lunch breaks with short afternoons to allow you to relax, discuss, and explore the beautiful location with your colleagues. A range of social activities will also be offered. More details to follow soon.
