Rotation in molecular clouds
(1999)
We have investigated a broad range of evidence concerning rotation in molecular clouds. As a consequence, we show that trends in specific angular momentum J/M and angular velocity Ω are inconsistent with certain models of ...
Magnetic field components analysis of the SCUPOL 850μm polarization data catalog
(Chicago, 2013)
We present an extensive analysis of the 850 μm polarization maps of the SCUBA Polarimeter Legacy (SCUPOL) Catalogue produced by Matthews et al., focusing exclusively on the molecular clouds and star-forming regions. For ...
Which molecular cloud structures are bound?
(IOP, 2021)
We analyze surveys of molecular cloud structures defined by tracers ranging from CO J = 1 → 0 through 13CO J = 1 → 0 to dust emission together with NH3 data. The mean value of the virial parameter and the fraction of mass ...
THE ROLE OF TURBULENT MAGNETIC RECONNECTION IN THE FORMATION OF ROTATIONALLY SUPPORTED PROTOSTELLAR DISKS
(IOP PUBLISHING LTDBRISTOL, 2012)
The formation of protostellar disks out of molecular cloud cores is still not fully understood. Under ideal MHD conditions, the removal of angular momentum from the disk progenitor by the typically embedded magnetic field ...
Dynamical equilibrium in the molecular ISM in 28 nearby star-forming galaxies
(IOP, 2020)
We compare the observed turbulent pressure in molecular gas, P-turb, to the required pressure for the interstellar gas to stay in equilibrium in the gravitational potential of a galaxy, P-DE. To do this, we combine arcsecond ...
ALMA observations of two massive and dense MALT90 clumps
(IOP, 2020)
We report Atacama Large Millimeter Array observations of 3 mm dust continuum emission and line emission, in HCO+, (HCO+)-C-13, N2H+, and CH3CN, toward two massive and dense clumps (MDCs) in early but distinct evolutionary ...
Gas turbulence in the dark matter assembly process: seeds for primordial star formatión.
(2014)
In this work I pcrformcd a number of cosrnological numcrical simulation of primordial gas with non-cquilibrium chemistry for 21 diffcrcnt spccies inclucling H2. HD and LiH molecular cooling. From cosmological init ial ...
Infall, outflow, and turbulence in massive star-forming cores in the G333 giant molecular cloud
(Royal Astronomical Society, 2015)
We present molecular line imaging observations of three massive molecular outflow sources,
G333.6–0.2, G333.1–0.4, and G332.8–0.5, all of which also show evidence for infall, within
the G333 giant molecular cloud (GMC). ...
Scaled up low-mass star formation in massive star-forming cores in the G333 giant molecular cloud
(Oxford Univ Press, 2016)
Three bright molecular line sources in G333 have recently been shown to exhibit signatures of infall. We describe amolecular line radiative transfer (RT) modelling process which is required to extract the infall signature ...
