Abstract

We have performed a multi-wavelength study toward a quasi-sinusoidal filament (CFG028.68-0.28). A new large-scale (CO)-C-12 J = 3 - 2 map was obtained from the China-Cologne Observation for SubMillimeter Astronomy (CCOSMA) 3m radio telescope. Based on the ATLASGAL catalog, we have identified 27 dust clumps in the filament. Through the relationship between the mass and radius of these clumps, 67% of these clumps are dense and massive enough to potentially form massive stars. The obtained CFE is similar to 11% in the filament. The filament has a linear mass density of similar to 305 M(circle dot)pc(-1), which is smaller than its critical mass to length ratio. This suggests that the external pressure from the neighboring H II regions may help prevent the filament from dispersing under the effects of turbulence. Comparing the energy injection from outflows and H II regions in the filament, the ionization feedback from the H II regions can help maintain the observed turbulence.
