DESCRIPTION:The long-period radio transients are a newly-discovered class 
 of Galactic radio sources that produce pulsed emission lasting tens of sec
 onds to several minutes\, repeating on timescales of tens of minutes to ho
 urs. Such cadence is unprecedented\, and there is currently no clear emiss
 ion mechanism or progenitor that can explain the observations\, which incl
 ude complex polarisation behaviour\, pulse microstructure\, and activity w
 indows that range from hours to decades.\n\nCould they be ultra-long perio
 d magnetars\, and connected to the phenomenon of Fast Radio Bursts? Could 
 they be white dwarf pulsars\, defying the expectations of the magnetic fie
 ld evolution of these stellar remnants? In this talk I will describe the t
 en discoveries made so far\, informative simulations of their evolution\, 
 the potential physical explanations\, and the prospects for detecting more
  of these sources in ongoing and upcoming radio surveys\, that will help u
 ncover their true nature.
