Binary Formation in a 100 μm Dark Massive Core
We report high-resolution ALMA observations toward a massive protostellar core C1-Sa (∼30 M _⊙ ) in the Dragon infrared dark cloud. At the resolution of 140 au, the core fragments into two kernels (C1-Sa1 and C1-Sa2) with a projected separation of ∼1400 ...

Fine structure of the density distribution in giant molecular clouds (GMCs) around W43 (G31+00+90 km s−1at ∼5.5 kpc) was analyzed using the FUGIN* CO-line survey at high-angular (20”∼0.5 pc) and velocity (1.3 km s−1) resolutions (*Four-receiver-system ...

Magnetic Fields in the Infrared Dark Cloud G34.43+0.24 [PDF]
Abstract We present the B-fields mapped in IRDC G34.43+0.24 using 850 μm polarized dust emission observed with the POL-2 instrument at the James Clerk Maxwell telescope. We examine the magnetic field geometries and strengths in the northern, central, and southern regions of the filament.

NIKA2 observations around LBV stars Emission from stars and circumstellar material [PDF]
Luminous Blue Variable (LBV) stars are evolved massive objects, previous to core-collapse supernova. LBVs are characterized by photometric and spectroscopic variability, produced by strong and dense winds, mass-loss events and very intense UV radiation ...

The initial conditions found in infrared dark clouds (IRDCs) provide insights on how high-mass stars and stellar clusters form. We have conducted high-angular resolution and high-sensitivity observations toward thirty-nine massive IRDC clumps, which have

Multicomponent Kinematics in a Massive Filamentary Infrared Dark Cloud [PDF]
Abstract To probe the initial conditions for high-mass star and cluster formation, we investigate the properties of dense filaments within the infrared dark cloud (IRDC) G035.39–00.33 (G035.39) in a combined Very Large Array and Green Bank Telescope mosaic tracing the NH3 (1, 1) and (2, 2) emission down to 0.08 pc scales.

Molecular line observations of infrared dark clouds. II. Physical conditions [PDF]
Using a source selection biased toward high-mass star-forming regions, we used a large velocity gradient code to calculate the H2 densities and CS column densities for a sample of Midcourse Space Experiment 8 mum infrared dark cores.
