Submitted papers

Active projects

• Melanie Johnston-Hollitt (VUW): New SNRs with the MWA (catalogue of SNRs at Dec-55) (Proposed before the GEG process was implemented and therefore available only as an MWA paper proposal)

• Hongquan Su (Curtin): HII region absorption measurements (MWA Student Project)

• Miroslav Filipovic, Ivan Bojicic, Timothy Galvin (Western Sydney University): Galactic Planetary Nebulae as seen by MWA

• Wenwu Tian, Hongquan Su, Xiaocong Cui (BAO): Identify TeV supernova remnants in GLEAM

• Dusan Onic & Miroslav Filipovic: Multiwavelength study of Kes 27

• Naomi McClure-Griffiths, Natasha Hurley-Walker, Loren Anderson – HII absorption toward the Galactic centre

Projects not yet proposed to GEG

• Anne Green, Sarah Reeves, Tara Murphy (USyd), MJH (VUW): Use GLEAM data to confirm remnants originally detected in MGPS and IR data.

• Melanie Johnston-Hollitt (Curtin/ICRAR): Testing novel source-finders (Hoff transforms)

"Open" projects: available for students or postdocs after discussion with the Galactic Continuum team

• The environment and star formation around SNR (originally Luke Hindson (VUW))

• Low-frequency emission and polarisation towards the Gum Nebula (originally Cormac Purcell (USyd))

Need polarisation data

Data processing

GLEAM and GLEAM-X processing are tracked on their own pages. MWATS also has data which could be used.
