Sulfur isotope ratios in the Large Magellanic Cloud

Y. Gong, C. Henkel, K. M. Menten +11

Sulfur isotope ratios have emerged as a promising tool for tracing stellar nucleosynthesis, quantifying stellar populations, and investigating the chemical evolution of galaxies. W…

Variations of the HCO, HCN, HNC, NH and NH deuterium fractionation in high-mass star-forming regions

A. G. Pazukhin, I. I. Zinchenko, E. A. Trofimova +2

We use spectra and maps of the and DCO, DCN, DNC, lines and ortho- and para-NHD lines, obtained with the IRAM-30m telescope…

The 107 GHz methanol transition is a dasar in G0.253+0.016

Alyssa Bulatek, Adam Ginsburg, Jeremy Darling +2

We present observations of population anti-inversion in the transition of CHOH (methanol) at 107.013831 GHz toward the Galactic Center cloud G0.253+0.016 ("The…

Star formation in the centre of NGC 1808 as observed by ALMA

Guangwen Chen, George J. Bendo, Gary A. Fuller +2

We present Atacama Large Millimeter/submillimeter Array (ALMA) observations of 85.69 and 99.02 GHz continuum emission and H42 and H40 lines emission from the central 1~kpc of…

ALMA and VLBA views on the outflow associated with an O-type protostar in G26.50+0.28

Gang Wu, Christian Henkel, Ye Xu +6

Protostellar jets and outflows are essential ingredients of the star formation process. A better understanding of this phenomenon is important in its own right as well as for many…

Gas, dust, and the CO-to-molecular gas conversion factor in low-metallicity starbursts

L. K. Hunt, F. Belfiore, F. Lelli +19

The factor relating CO emission to molecular hydrogen column density, XCO, is still subject to uncertainty, in particular at low metallicity. Here, to quantify XCO at two different…
