The physical and chemical structure of Sagittarius B2 VIIIa. Dust and ionized gas contributions to the full molecular line survey of 47 hot cores
T. Möller, P. Schilke, Á. Sánchez-Monge +2
Sagittarius B2 (Sgr B2) is a giant molecular cloud complex in the central molecular zone of our Galaxy hosting several sites of high-mass star formation. The two main centers of ac…
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…
Planck Galactic Cold Clumps at High Galactic Latitude-A Study with CO Lines
Fengwei Xu, Yuefang Wu, Tie Liu +28
Gas at high Galactic latitude is a relatively little-noticed component of the interstellar medium. In an effort to address this, forty-one Planck Galactic Cold Clumps at high Galac…
A search for cloud cores affected by shocked carbon chain chemistry in L1251
Xunchuan Liu, Y. Wu, C. Zhang +26
We searched for shocked carbon chain chemistry (SCCC) sources with CS abundances surpassing those of HCN towards the dark cloud L1251, using the Effelsberg telescope at K-b…
Planck Galactic Cold Clumps in Two Regions: the First Quadrant and the Anti-Center Direction Region
Chao Zhang, Yuefang Wu, Xunchuan Liu +13
Sixty five Planck Galactic cold clumps (PGCCs) from the first quadrant (IQuad) and thirty nine of PGCCs from the Anti-Center direction region (ACent) were observed in CO, $^…
The physical and chemical structure of Sagittarius B2 -- V. Non-thermal emission in the envelope of Sgr B2
F. Meng, Á. Sánchez-Monge, P. Schilke +8
The giant molecular cloud Sagittarius B2 (hereafter SgrB2) is the most massive region with ongoing high-mass star formation in the Galaxy. In the southern region of the 40-pc large…
The Physical and chemical structure of Sagittarius B2 -- IV. Converging filaments in the high-mass cluster forming region Sgr B2(N)
A. Schwörer, Á. Sánchez-Monge, P. Schilke +7
We have used an unbiased, spectral line-survey that covers the frequency range from 211 to 275 GHz and was obtained with ALMA (angular resolution of 0.4 arcsec) to study the small-…
SCOPE: SCUBA-2 Continuum Observations of Pre-protostellar Evolution - Survey Description and Compact Source Catalogue
D. J. Eden, Tie Liu, Kee-Tae Kim +157
We present the first release of the data and compact-source catalogue for the JCMT Large Program SCUBA-2 Continuum Observations of Pre-protostellar Evolution (SCOPE). SCOPE consist…
Distributed star formation throughout the Galactic Center cloud Sgr B2
A. G. Ginsburg, John Bally, Ashley Barnes +23
We report ALMA observations with resolution " at 3 mm of the extended Sgr B2 cloud in the Central Molecular Zone (CMZ). We detect 271 compact sources, most of which are…
The TOP-SCOPE survey of Planck Galactic Cold Clumps: Survey overview and results of an exemplar source, PGCC G26.53+0.17
Tie Liu, Kee-Tae Kim, Mika Juvela +11
The low dust temperatures (<14 K) of Planck Galactic Cold Clumps (PGCCs) make them ideal targets to probe the initial conditions and very early phase of star formation. TOP-SCOPE i…
Dense gas in molecular cores associated with Planck Galactic cold clumps
Jinghua Yuan, Yuefang Wu, Tie Liu +7
We present the first survey of dense gas towards Planck Galactic Cold Clumps (PGCCs). Observations in the J=1-0 transitions of HCO+ and HCN towards 621 molecular cores associated w…
Planck cold clumps in the Orionis complex: I. Discovery of an extremely young Class 0 protostellar object and a proto-brown dwarf candidate in a bright rimmed clump PGCC G192.32-11.88
Tie Liu, Qizhou Zhang, Kee-Tae Kim +37
We are performing a series of observations with ground-based telescopes toward Planck Galactic cold clumps (PGCCs) in the Orionis complex in order to systematically investigate…
