Dual-band Unified Exploration of Three CMZ Clouds (DUET): Cloud-wide Census of Continuum Sources Showing Low Spectral Indices
Published in Astronomy & Astrophysics, 697, A164, 2025
The survey maps the 20 km s-1 cloud, Sgr C, and dust-ridge cloud e at 1.3 and 3 mm with comparable 0.2-0.3 arcsec resolution. The widespread low spectral indices motivate new tests of compact optically thick structures, dust growth, and free-free emission in the Galactic Center.
