Optically thin HC3N/HC5N isotopologues yield 12C/13C ≈ 37 (≈48 after fractionation correction) in G+0.693, matching 3–5 kpc disc gas and implying bar-driven inflow into the CMZ.

Sulfur abundances in starless cores vary with local conditions instead of a single evolutionary parameter, and 0D chemical models cannot simultaneously match all observed carbon- and oxygen-bearing species.
ALMA data on nine cores along an arch in AG286.0716−1.8229 support triggered star formation induced by an expanding H II region.

High $^{12}$C/$^{13}$C isotopic ratios toward G+0.693-0.027: evidence for gas inflow to the Central Molecular Zone
Optically thin HC3N/HC5N isotopologues yield 12C/13C ≈ 37 (≈48 after fractionation correction) in G+0.693, matching 3–5 kpc disc gas and implying bar-driven inflow into the CMZ.
