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…
Synthetic observations of protostellar multiple systems
O. Lomax, A. P. Whitworth
Observations of protostars are often compared with synthetic observations of models in order to infer the underlying physical properties of the protostars. The majority of these mo…
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…
A theoretical perspective on the formation and fragmentation of protostellar discs
A. P. Whitworth, O. D. Lomax
We discuss the factors influencing the formation and gravitational fragmentation of protostellar discs. We start with a review of how observations of prestellar cores can be analys…
Temperature as a third dimension in column-density mapping of dusty astrophysical structures associated with star formation
K. A. Marsh, A. P. Whitworth, O. Lomax
We present PPMAP, a Bayesian procedure that uses images of dust continuum emission at multiple wavelengths to produce resolution-enhanced image cubes of differential column-density…
Are the majority of Sun-like stars single?
A. P. Whitworth, O. Lomax
It has recently been suggested that, in the field, of Sun-like stars () are single. We argue her…
On the effects of solenoidal and compressive turbulence in prestellar cores
O. Lomax, A. P. Whitworth, D. A. Hubber
We present the results of an ensemble of SPH simulations that follow the evolution of prestellar cores for . All the cores have the same mass, and start with the sa…
Simulating star formation in Ophiuchus
O. Lomax, A. P. Whitworth, D. A. Hubber +2
We have simulated star formation in prestellar cores, using SPH and initial conditions informed by observations of the cores in Ophiuchus. Because the observations are limited to t…
Collisions in young triple systems
Krisada Rawiraswattana, Oliver Lomax, Simon P. Goodwin
We perform N-body simulations of young triple systems consisting of two low-mass companions orbiting around a significantly more massive primary. We find that, when the orbits of t…
