It is an enigmatic example of a growing population of 'long-period radio transients' consistent with Galactic origins. Their nature is uncertain, and leading models invoke magnetic neutron stars or white dwarfs, potentially in close binary systems, to power them. GLEAM-X J1627-52 resides in the Galactic plane with a comparatively coarse localisation (~2 arcsecond). Here we study the localisation region to search for spectrophotometric signatures of a counterpart using time-domain searc","authors_text":"A. A. Chrimes, A. J. Levan, D. T. H. Steeghs, I.
