From 2D to 3D: Recovering Turbulent Density Dispersions from Noisy Data
Luz L. Jimenez Vela, Christoph Federrath, David C. Collins +1
Turbulence plays a central role in shaping the structure and dynamics of the interstellar medium (ISM), governing the star formation rate (SFR) and the initial mass function (IMF).…
ML in Astrophysical Turbulence I: Predicting Prestellar Cores in Magnetized Molecular Clouds using eXtreme Gradient Boosting
Nikhil Bisht, David C. Collins
Giant Molecular Clouds (GMCs) are dominated by supersonic turbulence, creating a complex network of shocks and filaments that regulate star formation. While the global inefficiency…
Collapsing molecular clouds with tracer particles: Part II, Collapse Histories
David C. Collins, Dan K. Le, Luz L. Jimenez Vela
In order to develop a complete theory of star formation, one essentially needs to know two things: what collapses, and how long it takes. This is the second paper in a series, wher…
Planck dust polarization power spectra are consistent with strongly supersonic turbulence
Kye A. Stalpes, David C. Collins, Kevin M. Huffenberger
The polarization of the Cosmic Microwave Background (CMB) is rich in information but obscured by foreground emission from the Milky Way's interstellar medium (ISM). To uncover rela…
