Discovery of Interstellar 2-Cyanoindene (2-CHCN) in GOTHAM Observations of TMC-1
Madelyn L. Sita, P. Bryan Changala, Ci Xue +12
We present laboratory rotational spectroscopy of five isomers of cyanoindene (2-, 4-, 5-, 6-, and 7-cyanoindene) using a cavity Fourier-transform microwave spectrometer operating b…
A detailed temperature map of the archetypal protostellar shocks in L1157
S. Feng, H. B. Liu, P. Caselli +5
We present sensitive (1,1)--(7,7) line images from the Karl G. Jansky Very Large Array toward successive shocks, which are associated with the blueshifted outflow lobe d…
A Search for Heterocycles in GOTHAM Observations of TMC-1
Timothy J. Barnum, Mark A. Siebert, Kin Long Kelvin Lee +9
We have conducted an extensive search for nitrogen-, oxygen- and sulfur-bearing heterocycles toward Taurus Molecular Cloud 1 (TMC-1) using the deep, broadband centimeter-wavelength…
PDRs4All: A JWST Early Release Science Program on radiative feedback from massive stars
Olivier Berné, Émilie Habart, Els Peeters +134
Massive stars disrupt their natal molecular cloud material through radiative and mechanical feedback processes. These processes have profound effects on the evolution of interstell…
First images of phosphorus molecules towards a proto-Solar analog
Jennifer B. Bergner, Andrew M. Burkhardt, Karin I. Oberg +2
The chemistry of phosphorus in star- and planet-forming regions is poorly understood, despite the central role of phosphorus in terrestrial biochemistry. We present ALMA Band 3 and…
