Quantify the influence of nearby H II regions on NGC6334I

Quantify the influence of nearby H II regions on NGC6334I through photoionizing radiation and modifications of the magnetic-field geometry, to determine whether these effects contribute to the observed polarization properties.

Background

The paper analyzes polarization-angle dispersion in NGC6334I and notes that nearby expanding H II-region bubbles could alter the magnetic-field geometry or expose the region to additional photoionizing radiation. The authors find that the available analysis does not establish whether these neighboring regions affect the observed polarization, leaving their contribution unresolved.

References

However, we cannot rule out the influence of other H { regions on , either through photoionizing radiation or their potential impact on the B-field geometry. Quantifying these effects would require further analysis in future work.
