Unveiling a network of parallel filaments in the Infrared Dark Cloud G14.225-0.506
Gemma Busquet, Qizhou Zhang, Aina Palau +10
We present the results of combined NH3(1,1) and (2,2) line emission observed with the Very Large Array and the Effelsberg 100m telescope of the Infrared Dark Cloud G14.225-0.506. T…
A new radio recombination line maser object toward the MonR2 HII region
I. Jimenez-Serra, A. Baez-Rubio, V. M. Rivilla +4
We report the detection of a new radio recombination line (RRL) maser object toward the IRS2 source in the MonR2 ultracompact HII region. The continuum emission at 1.3mm and 0.85mm…
A Double-Jet System in the G31.41+0.31 Hot Molecular Core
Luca Moscadelli, Jing Jing Li, Riccardo Cesaroni +3
This work presents a detailed study of the gas kinematics towards the "Hot Molecular Core" (HMC) G31.41+0.31 via multi-epoch VLBI observations of the H2O 22 GHz and CH3OH 6.7 GHz m…
Early stages of cluster formation: fragmentation of massive dense cores down to ~1000 AU
Aina Palau, Asunción Fuente, Josep M. Girart +11
In order to study the fragmentation of massive dense cores, which constitute the cluster cradles, we observed with the PdBI in the most extended configuration the continuum at 1.3…
The Protocluster G18.67+0.03: A Test Case for Class I Methanol Masers as Evolutionary Indicators for Massive Star Formation
C. J. Cyganowski, C. L. Brogan, T. R. Hunter +4
We present high angular resolution Submillimeter Array (SMA) and Karl G. Jansky Very Large Array (VLA) observations of the massive protocluster G18.67+0.03. Previously targeted in…
Forming an O Star via Disk Accretion?
Keping Qiu, Qizhou Zhang, Henrik Beuther +1
We present a study of outflow, infall, and rotation in a ~10^5 Lsun (solar luminosity) star-forming region, IRAS 18360-0537, with Submillimeter Array (SMA) and IRAM 30m observation…
Fragmentation and OB Star Formation in High-Mass Molecular Hub-Filament System
Hauyu Baobab Liu, Izaskun Jiménez-Serra, Paul T. -P. Ho +3
Filamentary structures are ubiquitously seen in the interstellar medium. The concentrated molecular mass in the filaments allows fragmentation to occur in a shorter timescale than…
Different Evolutionary Stages in the Massive Star Forming Region W3 Main Complex
Yuan Wang, Henrik Beuther, Qizhou Zhang +4
We observed three high-mass star-forming regions in the W3 high-mass star formation complex with the Submillimeter Array and IRAM 30 m telescope. These regions, i.e. W3 SMS1 (W3 IR…
Chemical segregation toward massive hot cores: The AFGL2591 star forming region
I. Jimenez-Serra, Q. Zhang, S. Viti +2
We present high angular resolution observations (0.5"x0.3") carried out with the Submillimeter Array (SMA) toward the AFGL2591 high-mass star forming region. Our SMA images reveal…
H2D+ in the high mass star-forming Region Cygnus-X
Thushara Pillai, Paola Caselli, Jens Kauffmann +3
H2D+ is a primary ion which dominates the gas-phase chemistry of cold dense gas. Therefore it is hailed as a unique tool in probing the earliest, prestellar phase of star formation…
Dense gas in IRAS 20343+4129: an ultracompact HII region caught in the act of creating a cavity
F. Fontani, Aina Palau, G. Busquet +5
The intermediate- to high-mass star-forming region IRAS 20343+4129 is an excellent laboratory to study the influence of high- and intermediate-mass young stellar objects on nearby…
SMA and Spitzer Observations of Bok Glouble CB17: A Candidate First Hydrostatic Core?
Xuepeng Chen, Hector G. Arce, Michael M. Dunham +5
We present high angular resolution SMA and Spitzer observations toward the Bok globule CB17. SMA 1.3mm dust continuum images reveal within CB17 two sources with an angular separati…
Temperature and kinematics of protoclusters with intermediate and high-mass stars: the case of IRAS 05345+3157
F. Fontani, P. Caselli, Q. Zhang +3
We have mapped at small spatial scales the temperature and the velocity field in the protocluster associated with IRAS 05345+3157, which contains both intermediate-/high-mass proto…
Discovery of A Binary System in IRAM 04191+1522
Xuepeng Chen, Hector G. Arce, Michael M. Dunham +1
We present high angular resolution observations of the Class 0 protostar IRAM04191+1522, using the Submillimeter Array (SMA). The SMA 1.3 mm continuum images reveal within IRAM0419…
