    Thermodynamics of Giant Molecular Clouds: The Effects of Dust Grain Size by Nadine H. Soliman, Philip F. Hopkins, Michael Y. Grudić

    Published 2024-01-01
    “…Motivated by this, we investigate the effects of similar GSD variations on the thermochemistry and evolution of giant molecular clouds (GMCs) using magnetohydrodynamic simulations spanning a range of cloud masses and grain sizes, which explicitly incorporate the dynamics of dust grains within the full-physics framework of the STARFORGE project. …”

    The H2 Glow of a Quiescent Molecular Cloud Observed with JWST by Paul F. Goldsmith, Shengzhe Wang, Xin Wang, Raphael Skalidis, Gary A. Fuller, Di Li, Chao-Wei Tsai, Lile Wang, Donghui Quan

    Published 2025-01-01
    “…We report JWST MIRI/MRS observations of the H _2 S (1) 17.04 μ m transition in two regions in the boundary of the Taurus molecular cloud. The two regions, denoted “Edge” (near the relatively sharp boundary of the ^13 CO J  = 1 → 0 emission) and “Peak” (the location of the strongest H _2 emission observed with Spitzer), have average intensities of 14.5 and 32.1 MJy sr ^−1 , respectively. …”

    Exploring the Wolf Approach to Constraining NIR Extinction Laws in the Corona Australis Molecular Cloud by Botao Jiang, Jun Li, Xi Chen

    Published 2025-01-01
    “…The viability of the star count (Wolf) method is assessed as a means of constraining the near-infrared (NIR) extinction law toward the Corona Australis molecular cloud. Using deep JHK _S photometry from the VISIONS survey, extinction maps with 1′ spatial resolution are constructed. …”

    Rethinking Habitability Using Biogenic Precursors: Formaldehyde in Millimeter Molecular Clouds of the Inner Galaxy by N. B. Baharin, A. A. Nazri, Z. Rosli, Z. Z. Abidin, H. A. Tajuddin, J. Esimbek, D. L. Li, X. Tang

    Published 2025-01-01
    “…We present a comprehensive study of formaldehyde (H _2 CO) absorption and radio recombination line (H _110 _α ) emission in 215 molecular clouds from the Bolocam Galactic Plane Survey, observed using the Nanshan 25 m radio telescope. …”

    The Magnetic Keys to Massive Star Formation: The Western η Carinae Giant Molecular Cloud by Peter J. Barnes, Stuart D. Ryder, Giles Novak, Laura M. Fissel

    Published 2025-01-01
    “…We present SOFIA/HAWC+ continuum polarization data on the magnetic fields ( B fields) threading 17 pc-scale massive molecular clumps at the western end of the η Carinae giant molecular cloud (Region 9 of the Galactic Census of High- and Medium-mass Protostars, or CHaMP, representing all stages of star formation from pre-stellar to dispersing via feedback), revealing important details about the field morphology and role in the gas structures of this clump sample. …”

    Differential virial analysis: a new technique to determine the dynamical state of molecular clouds by Mark R. Krumholz, Charles J. Lada, Jan Forbrich

    Published 2025-07-01
    “…Since molecular clouds form stars, at least some parts of them must be in a state of collapse. …”
