8th Phantom Users Workshop 2026
How do stars and planets form? How do black holes accrete? How does dust form in the winds of giant stars? How does the common envelope get ejected?
All of these questions can be answered using Phantom, a smoothed particle hydrodynamics code, MCFOST, a class-leading radiative transfer code, and Shamrock, a GPU-first SPH code in the Phantom family.
We are delighted to host the 8th Phantom code family users workshop in 2026 at Macquarie University in Sydney, Australia.
The goal of a Phantom workshop is to bring together users to foster collaboration, help existing users learn how to use the code better, explore how new features can be applied across astrophysical problems, extend the codebase to solve new physics or problems, and create new setups for mutual collaboration.
1. To consolidate development efforts
2. To set a roadmap for development priorities
3. To grow the user community, and especially to encourage sideways interaction between users
We will set each afternoon of the workshop as a hackfest, to collaboratively implement new features and tests
Dates: Tuesday 9th - Friday 12th June 2026
Venue: Macquarie University, Sydney, Australia
Sponsors: We are grateful to AFRAN for sponsorship.
Each day will feature a series of science talks in the morning, with afternoons focused around collaborative hack sessions. A welcome event will be held on the evening of the first day (Tuesday, 9th June). The conference dinner will be held on Thursday 11th June.
Registered participants will be listed here after registration opens.
The workshop will be held at:
Macquarie University
Sydney, New South Wales
Australia
Registration and abstract submission will open in early March 2026.
Important deadlines:
If you do not wish to give a talk or poster, just enter "none" for the title and abstract.
The registration form will ask if you accept your presentation being recorded and publicly posted on the Phantom YouTube page.
