Search for radio pulsations from exotic young pulsars in globular clusters

Abstract

The formation of exotic young compact objects through merge-induced collapse (MIC) and accretion-induced collapse (AIC) is still a topic of debate due to limited observational evidence. Core-collapsed globular cluster provides an ideal place for the production of young and energetic neutron stars through MIC/AIC, thanks to their rich dynamical environment. Recent discoveries of several long-period pulsars, a repeating fast radio burst, and a mass-gap compact object in globular clusters provide significant insights into the production of exotic compact objects formed through MIC/AIC. Here we propose a systematic search in several Galactic core-collapsed globular clusters to search for radio pulsations from MIC/AIC outcomes. The proposed observations aim to discover new young exotic pulsars (including millisecond magnetars) and potential fast radio bursts. These findings could contribute to our understanding of the MIC/AIC processes, as well as dynamics in globular clusters and pulsar astronomy.
