The integrated intensity (0th moment) maps of the H2CO and CH3CN line emission toward the three clouds. The inner and outer red dashed loops in the left panels show the ALMA primary-beam responses at 50% and 30%, respectively. The left panels show the integrated intensities of H2CO 30,3–20,2 and CH3CN 120–110/ 121–111, while the right panels are the zoomed-in views of the dashed boxes in the left panels. The blue contours show the 1.3 mm dust continuum at levels of 5 and 20 ×σ, where σ = 40 µJy beam−1 . The green ‘+’ symbols illustrate the peak positions of the cores identified from the 1.3 mm continuum. (The complete figure set (7 images) is available in the online journal.) -- astro-ph.GA

ALMA Observations of Massive Clouds in the Central Molecular Zone: External-Pressure-Confined Dense Cores and Salpeter-like Core Mass Functions

by Keith CowingDecember 3, 2024December 3, 2024

We present Atacama Large Millimeter/submillimeter Array (ALMA) Band 6 (1.3 mm) observations of dense cores in three massive molecular clouds within the Central Molecular Zone (CMZ) of the Milky Way, […]

The NIRCam (Near-Infrared Camera) instrument on NASA’s James Webb Space Telescope’s reveals a portion of the Milky Way’s dense core in a new light. An estimated 500,000 stars shine in this image of the Sagittarius C (Sgr C) region, along with some as-yet unidentified features. A large region of ionized hydrogen, shown in cyan, contains intriguing needle-like structures that lack any uniform orientation. NASA, ESA, CSA, STScI, and S. Crowe (University of Virginia).
