abstract

We investigate pre-merger coherent radio emission from neutron star mergers arising due to the magnetospheric interaction between compact objects. We consider two plausible radiation mechanisms, and show that if one neutron star has a surface magnetic field $B_{\rm s} \ge 10^{12}$G, coherent millisecond radio bursts with characteristic temporal morphology and inclination angle dependence are observable to Gpc distances with next-generation radio facilities. We explore multi-messenger and multi-wavelength methods of identification of a NS merger origin of radio bursts, such as in fast radio burst surveys, triggered observations of gamma-ray bursts and gravitational wave events, and optical/radio follow-up of fast radio bursts in search of kilonova and radio afterglow emission. We present our findings for current and future observing facilities, and make recommendations for verifying or constraining the model.

  1. Assessing the Impact of Instrumental Requirements on the Scientific Performance of the Einstein Telescope

    astro-ph.IM 2026-07 accept novelty 6.0 of 10

    Degrading the Einstein Telescope's sensitivity in specific frequency bands hurts different science goals in predictable ways, but the mission remains scientifically strong even in the worst modelled cases.

    astro-ph.HE 2026-07 conditional novelty 6.0 of 10

    No gravitational-wave counterpart is statistically associated with any of 47 Einstein Probe fast X-ray transients in the O4b run; 90% exclusion distances of ~178 Mpc (BNS) and ~349 Mpc (NSBH) disfavor nearby compact-b...

  3. Alfven-winged pulsar

    astro-ph.HE 2026-04 unverdicted novelty 6.0 of 10

    A neutron star in a compact binary generates relativistic Alfven wings that carry most of the intersected electromagnetic power and may produce periodic pulsar-like emission.

  4. Rapid Response Triggering for Radio Transients with the SKA Observatory

    astro-ph.IM 2026-07 accept novelty 3.0 of 10

    SKA-Low and SKA-Mid should implement automated rapid-response triggering on external and internal alerts to enable early radio observations of diverse transients.
