Journal Article
Fan, H., Rocha, C. M. R., Cordiner, M., Linnartz, H., Cox, N. L. J., Farhang, A., …Cami, J. (2024). The EDIBLES survey: VII. A survey of C2 and C3 in interstellar clouds. Astronomy & Astrophysics, 681, Article A6. https://doi.org/10.1051/0004-6361/202243910

Context. Small linear carbon chain radicals such as C2 and C3 act as both the building blocks and dissociation fragments of larger carbonaceous species. Their rotational excitation traces the temperature and density of local environments. However, th... Read More about The EDIBLES survey: VII. A survey of C2 and C3 in interstellar clouds.
