PHISCC workshop 2025

Motivation

The series of annual PHISCC workshops started in 2009 and aims at bringing together the community interested in HI research with the SKA pathfinders and precursors. The goal of the PHISCC workshops is to foster collaboration and exchange of ideas both from a scientific and technical point of view, with a strong focus on engaging early-career researchers.

With most major new and upgraded facilities for 21 cm research operational, the PHISCC 2025 workshop will focus on the latest HI results in the broader multi-wavelength context and in connection with theory and simulations.

Workshop sessions (22 - 24 September 2025)

The workshop sessions will cover a broad range of science topics:

• HI results on gas accretion and star formation in the context of a multi-phase ISM and CGM

• Galaxy dynamics

• Interaction between galaxies and the surrounding environment

• AGN feeding and feedback

• The evolution of the HI properties of galaxies with redshift

• Predictions from and comparison with theory and simulations

Besides regular contributed talks, the SOC has included in the program joint talks given by multiple attendees. Joint talks will allow more participants to present their results and make for a more dynamic workshop. See the program page for more details.

Breakout sessions (25 - 26 September 2025)

Following the workshop, the following breakout sessions will cover several recent developments on HI surveys, observations, data reduction  and analysis:

• New and future instrumentations

• Source Finding

• Source Characterisation

• Kinematical Modelling 

• Observing HI in the simulations

• Techniques for continuum subtraction

• Visualisation

• Image quality in the era of big data

In addition to these, there will be a Virtual Reality hands-on session, which will allow you to visualise your own cube in VR.

Finally, several short team meetings will take place:

• FLASH

• MeerKAT Fornax Survey

• Laduma

• MHONGOOSE

• WALLABY
