DESCRIPTION:The long-period radio transients are a newly-disco
 vered class of Galactic radio sources that produce
  pulsed emission lasting tens of seconds to severa
 l minutes\, repeating on timescales of tens of min
 utes to hours. Such cadence is unprecedented\, and
  there is currently no clear emission mechanism or
  progenitor that can explain the observations\, wh
 ich include complex polarisation behaviour\, pulse
  microstructure\, and activity windows that range 
 from hours to decades.\n\nCould they be ultra-long
  period magnetars\, and connected to the phenomeno
 n of Fast Radio Bursts? Could they be white dwarf 
 pulsars\, defying the expectations of the magnetic
  field evolution of these stellar remnants? In thi
 s talk I will describe the ten discoveries made so
  far\, informative simulations of their evolution\
 , the potential physical explanations\, and the pr
 ospects for detecting more of these sources in ong
 oing and upcoming radio surveys\, that will help u
 ncover their true nature.
