G0.253+0.016, commonly referred to as “the Brick” and located within the Central Molecular Zone, is one of the densest (≈ 103−4 cm−3) molecular clouds in the Galaxy to lack signatures of widespread star formation. We set out to constrain the origins of an arc-shaped molecular line emission feature located within the cloud. We determine that the arc, centred on {l0, b0} = {0. ◦248, 0. ◦018}, has a radius of 1.3 pc and kinematics indicative of the presence of a shell expanding at 5.2+2.7 −1.9 km…
