The physical and chemical structure of Sagittarius B2 -- VI. UCHII regions in Sgr B2
Fanyi Meng, Álvaro Sánchez-Monge, Peter Schilke +8
The giant molecular cloud Sagittarius B2 (hereafter SgrB2) is the most massive region with ongoing high-mass star formation in the Galaxy. Two ultra-compact HII (UCHII) regions wer…
Methanol deuteration in high-mass protostars
M. L. van Gelder, J. Jaspers, P. Nazari +6
The deuteration of molecules forming in the ices such as methanol (CHOH) is sensitive to the physical conditions during their formation in dense cold clouds and can be probed t…
The first CO+ image: Probing the HI/H2 layer around the ultracompact HII region Mon R2
S. P. Trevino-Morales, A. Fuente, A. Sanchez-Monge +12
The CO+ reactive ion is thought to be a tracer of the boundary between a HII region and the hot molecular gas. In this study, we present the spatial distribution of the CO+ rotatio…
Deuteration and evolution in the massive star formation process: the role of surface chemistry
F. Fontani, G. Busquet, Aina Palau +5
An ever growing number of observational and theoretical evidence suggests that the deuterated fraction (column density ratio between a species containing D and its hydrogenated cou…
A necklace of dense cores in the high-mass star forming region G35.20-0.74N: ALMA observations
Á. Sánchez-Monge, M. T. Beltrán, R. Cesaroni +13
The present study aims at characterizing the massive star forming region G35.20N, which is found associated with at least one massive outflow and contains multiple dense cores, one…
Ubiquitous argonium (ArH) in the diffuse interstellar medium -- a molecular tracer of almost purely atomic gas
Peter Schilke, David A. Neufeld, Holger S. P. Müller +14
We describe the assignment of a previously unidentified interstellar absorption line to ArH and discuss its relevance in the context of hydride absorption in diffuse gas with a…
