Long-period radio transients (LPTs) are an emerging group of radio transients that show periodic polarised radio bursts with periods varying from a few minutes to a few hours. Fewer than a dozen LPTs have been detected so far, and their origin remains unclear. The first example of an LPT to be detected at both radio and X-ray energies was reported just last month. Now, Anumarlapudi et al. report the discovery of a new 1.5 hr LPT, ASKAP J144834−685644, which has been detected at radio, optical and X-rays. It shows a steep radio spectrum and polarised radio bursts, which resemble the radio emission in known LPTs. The images above are 30 arcsecond cut-outs of optical (g, r, i composite) images of the field of ASKAP J1448−6856 using the Dark Energy Camera (DECam) as a part of the DECam Plane Survey (DECaPS). The image on the left was taken during the flaring state and the image on the right during the quiescent state. The lime dashed circle shows the error circle (2.5 arcseconds) of ASKAP J1448−6856. (The red and green streaks are image artefacts.) East is to the left and north is to the top of the image. Combining multi-wavelength information, the team infer that ASKAP J144834−685644 may be a near edge-on magnetic white dwarf binary (MWD), although they cannot fully rule out ASKAP J144834−685644 being an isolated white dwarf pulsar or even a transitional millisecond pulsar. If ASKAP J144834−685644 is a MWD binary, the observed broadband spectral energy distribution can be explained by emission from an accretion disk. This hints that some fraction of optically bright LPTs may be accreting binaries with the radio period being the orbital period
