Detection of Cyclotron Absorption in the Radio Emission of GPM 1839-10
Yunpeng Men, Ewan Barr, Yuanhong Qu +8
GPM 1839-10 is an intriguing long-period radio transient (LPT), distinguished by its activity spanning at least three decades and its highly unusual emission characteristics. These…
A new long period radio transient: Discovery of pulses repeating every 1.16 hours from ASKAP J175534.9-252749.1
Samuel J. McSweeney, Natasha Hurley-Walker, Csanád Horváth +7
We report the discovery of several new pulses from the source ASKAP J175534.9-252749.1 (J1755-2527), originally identified from a single 2-min long pulse, confirming it as a long p…
A long-period radio transient active for three decades
N. Hurley-Walker, N. Rea, S. J. McSweeney +22
Recently several long-period radio transients have been discovered, with strongly polarised coherent radio pulses appearing on timescales between tens to thousands of seconds [1,2]…
A 2.9-hour periodic radio transient with an optical counterpart
N. Hurley-Walker, S. J. McSweeney, A. Bahramian +12
We present a long-period radio transient (GLEAM-X J0704-37) discovered to have an optical counterpart, consistent with a cool main sequence star of spectral type M3. The radio puls…
