The Galactic Center Molecular Cloud Survey. II. A Lack of Dense Gas & Cloud Evolution along Galactic Center Orbits [PDF]
, 2016 We present the first systematic study of the density structure of clouds found in a complete sample covering all major molecular clouds in the Central Molecular Zone (CMZ; inner $\sim{}200~\rm{}pc$) of the Milky Way.

Fragmentation in molecular clouds [PDF]
Symposium - International Astronomical Union, 1991 B209. Fragments are detected in the outer parts of the B209 molecular cloud in a region of density 1000 cm−3 using 12CO, 13CO, H2CO, IRAS 60 and 100 μm images, discernable as velocity components, and have characteristics: <Rfragment>∼ 0.4 pc; <Mfragment>∼ 2 M⊙; <MVRfragment>∼ 1.6 M⊙ km/s pc; Tgas ∼ 11 K; Tdust> ∼ 16 K??. The system

The environment of Tycho: possible interaction with molecular cloud [PDF]
, 2004 The Tycho supernova remnant (SNR), as one of the few historical SNRs, has been widely studied in various wavebands. Observations show evidence that Tycho is expanding in a medium with density gradient and possibly interacting with dense ambient medium ...

Gravitational fragmentation caught in the act: the filamentary Musca molecular cloud [PDF]
, 2015 Filamentary structures are common in molecular clouds. Explaining how they fragment to dense cores is a missing step in understanding their role in star formation.

THE PHYSICAL CONDITIONS IN A PRE-SUPER STAR CLUSTER MOLECULAR CLOUD IN THE ANTENNAE GALAXIES [PDF]
, 2015 We present an analysis of the physical conditions in an extreme molecular cloud in the Antennae merging galaxies. This cloud has properties consistant with those required to form a globular cluster. We have obtained ALMA CO and 870 μm observations of the

Light Element Nucleosynthesis in a Molecular Cloud Interacting with a Supernova Remnant and the Origin of Beryllium-10 in the Protosolar Nebula [PDF]
, 2014 The presence of short-lived radionuclides in the early solar system provides important information about the astrophysical environment in which the solar system formed.

SUPERNOVA DRIVING. I. THE ORIGIN OF MOLECULAR CLOUD TURBULENCE [PDF]
, 2015 Turbulence is ubiquitous in molecular clouds (MCs), but its origin is still unclear because MCs are usually assumed to live longer than the turbulence dissipation time.

‘The Brick’ is not abrick: a comprehensive study of the structure and dynamics of the central molecular zone cloud G0.253+0.016 [PDF]
Monthly notices of the Royal Astronomical Society, 2019 In this paper we provide a comprehensive description of the internal dynamics of G0.253+0.016 (a.k.a. 'the Brick'); one of the most massive and dense molecular clouds in the Galaxy to lack signatures of widespread star formation. As a potential host to a
