Sgr B2(N2b) Archives

Selection of rotational transitions of CH317OH covered by the ReMoCA survey. The LTE synthetic spectrum of CH317OH used to derive its column density toward Sgr B2(N2b) is displayed in red and overlaid on the observed spectrum shown in black. The blue synthetic spectrum contains the contributions of all molecules identified in our survey so far, including CH317OH . The values written below each panel correspond from left to right to the half-power beam width, the central frequency in MHz, the width in MHz of each panel in parentheses, and the continuum level in K of the baseline-subtracted spectra in brackets. The y-axis is labeled in brightness temperature units (K). The dotted line indicates the 3σ noise level. -- astro-ph.GA

Investigation of the Rotational Spectrum of CH317OH and its Tentative Detection Toward Sagittarius B2(N)

by Keith CowingJuly 13, 2024July 7, 2024

Methanol is an abundant molecule in space. The column density of CH138OH is in some star-forming regions so high that the search for CH317OH is promising. But only very few […]
