Characterising lognormal fractional-Brownian-motion density fields with a Convolutional Neural Network
M. L. Bates, A. P. Whitworth, O. D. Lomax
In attempting to quantify statistically the density structure of the interstellar medium, astronomers have considered a variety of fractal models. Here we argue that, to properly c…
L1495 Revisited: A PPMAP View of a Star-Forming Filament
A. D. P. Howard, A. P. Whitworth, K. A. Marsh +4
We have analysed the Herschel and SCUBA-2 dust continuum observations of the main filament in the Taurus L1495 star forming region, using the Bayesian fitting procedure PPMAP. (i)…
Bipolar H{\sc ii} regions produced by cloud/cloud collisions
Anthony Whitworth, Oliver Lomax, Scott Balfour +3
We suggest that Bipolar H{\sc ii} Regions may be the aftermath of collisions between clouds. Such a collision will produce a shock-compressed layer, and a star cluster can then con…
Dust in the Eye of Andromeda
K. A. Marsh, A. P. Whitworth, M. W. L. Smith +2
We present new Herschel-derived images of warm dust in the Andromeda Galaxy, M31, with unprecedented spatial resolution (~ 30 pc), column density accuracy, and constraints on the t…
Modelling the structure of star clusters with fractional Brownian motion
O. Lomax, M. L. Bates, A. P. Whitworth
The degree of fractal substructure in molecular clouds can be quantified by comparing them with Fractional Brownian Motion (FBM) surfaces or volumes. These fields are self-similar…
Multi-temperature mapping of dust structures throughout the Galactic Plane using the PPMAP tool with Herschel Hi-GAL data
K. A. Marsh, A. P. Whitworth, O. Lomax +13
We describe new Hi-GAL based maps of the entire Galactic Plane, obtained using continuum data in the wavelength range 70-500 m. These maps are derived with the PPMAP procedure,…
: Characterising the structure of young star clusters
S. E. Jaffa, A. P. Whitworth, O. Lomax
Many young star clusters appear to be fractal, i.e. they appear to be concentrated in a nested hierarchy of clusters within clusters. We present a new algorithm for statistically a…
