Description
In this presentation, I will provide an update on the status of the MWA archive, backend systems, MWA ASVO enhancements and introduce the real-time beamformer for the MWA.
In May 2026, we released a beta version of an imaging feature for the MWA ASVO data portal. The main use case for this feature is to allow non-expert researchers to generate quick look images of MWA observations. Users can opt to generate basic images from raw visibility observations. The MWA ASVO will select the most appropriate calibration solution, then convert and correct the visibilities and apply the calibration solution before executing André Offringa's WSClean imaging tool. The user can opt to just download the FITS image, all WSClean output or all WSClean ouput plus the intermediate CASA measurement set. This beta version will keep being refined over the coming months based on user feedback. This part of the presentation will give a brief introduction to the feature, describe how it works, it's limitations and show some sample output.
The MWAX Real-time Beamformer is operational and progressing through a science commissioning phase in this semester of observing. A multi-disciplined team that designed and developed the system included members of the MWA Operations team (Christopher Phillips, Andrew Williams, Jake Jones and myself), The MWA Pulsars and Fast Transients team (Ramesh Bhat, Oscar Gordon, Christopher Lee), Ian Morrison from AstroSignal and Bradley Meyers (via the "AusSRC Science Enabling Projects"). This presentation will provide a description of the beamformer, show some sample output, describe its current status and future enhancements planned for the next release.
