We present a catalogue of filamentary structures identified in the SARAO (South African Radio Astronomy Observatory) MeerKAT 1.3 GHz Galactic Plane Survey (SMGPS). We extract 933 filaments across the survey area, 803 of which (⁠ ⁠) are associated with extended radio structures (e.g. supernova remnants and H ii regions), whilst 130 (⁠ ⁠) are largely isolated.

Searches for transient radio sources, independent of any multiwavelength trigger, have traditionally been hindered by a combination of sensitivity and field-of-view. However this has changed with the advent of the Square Kilometre Array (SKA) Pathfinders – the Murchison Widefield Array (MWA; Tingay et al. 2013; Wayth et al. 2018), the Low Frequency Array (van Haarlem et al. 2013), MeerKAT (Jonas & MeerKAT Team 2016), and the Australian SKA Pathfinder (ASKAP; Hotan et al. 2021).

Stars are assembled in molecular clouds through the gravitational collapse of dense cores of gas and dust (e.g. Shu, Adams & Lizano 1987; Di Francesco et al. 2007; Ward-Thompson et al. 2007; Dunham et al. 2014a; Pineda et al. 2023). The final masses of stars are set during the protostellar stage of star formation, when the forming protostar is embedded within, and accreting material from, its parent dense core.
