A multi-wavelength observation and investigation of six infrared dark clouds
Chuan-Peng Zhang, Jing-Hua Yuan, Guang-Xing Li +2
Context. Infrared dark clouds (IRDCs) are ubiquitous in the Milky Way, yet they play a crucial role in breeding newly-formed stars. Aims. With the aim of further understanding the…
Criteria for gravitational instability and quasi-isolated gravitational collapse in turbulent medium
Guang-Xing Li
We study the evolution of structures in turbulent, self-gravitating media, and present an analytical criterion …
Revealing a spiral-shaped molecular cloud in our galaxy - Cloud fragmentation under rotation and gravity
Guang-Xing Li, Friedrich Wyrowski, Karl Menten
The dynamical processes that control star formation in molecular clouds are not well understood, and in particular, it is unclear if rotation plays a major role in cloud evolution.…
ATLASGAL -- A Galaxy-wide sample of dense filamentary structures
Guang-Xing Li, J. S. Urquhart, S. Leurini +4
[Abridged] Aims. We study the properties of filamentary structures from the ATLASGAL survey. Methods. We use the DisPerSE algorithm to identify spatially coherent structures locate…
Gravitational acceleration and edge effects in molecular clouds
Guang-Xing Li, Andi Burkert, Tom Megeath +1
Gravity plays important roles in the evolution of molecular clouds. We present an acceleration mapping method to estimate the acceleration induced by gravitational interactions in…
Probing the multi-scale interplay between gravity and turbulence - Power-law like gravitational energy spectra of the Orion Complex
Guang-Xing Li, Andreas Burkert
Gravity plays a determining role in the evolution of the molecular ISM. In \citet{2016arXiv160304342L}, we proposed a measure called gravitational energy spectrum to quantify the i…
Constructing multi-scale gravitational energy spectra from molecular cloud surface density PDF -- Interplay between turbulence and gravity
Guang-Xing Li, Andreas Burkert
(Abridged) We derive an analytical formula which provides estimates on multiscale gravitational energy distribution using the observed surface density PDF. Our analytical formalism…
