We estimate that this method could significantly increase the volume of the universe in which gravitational wave (GW) counterparts—like GRB 170817A—can be detected, potentially expanding it by nearly an order of magnitude. To further this progress, we are excited to introduce a versatile, open-source tool: the Gamma-ray Targeted Search (GTS). Leveraging the newly developed Gamma-ray Data Tools (GDT), the GTS enables users to conduct custom searches for sub-threshold signals within GBM CTTE data at specified times (GW event times). Importantly, because the GTS is built on the GDT framework, it can also analyze GBM-like data from other missions, including BurstCube, Glowbug and the upcoming StarBurst mission. In this discussion, we will highlight the GTS's capabilities, recent significant results, and outline future enhancements aimed at creating a multi-mission targeted search. This expanded functionality would integrate the strengths of various gamma-ray instruments, facilitating deeper and more comprehensive explorations of the gamma-ray sky. |
