A precise symbolic emulator of the linear matter power spectrum
Deaglan J. Bartlett, Lukas Kammerer, Gabriel Kronberger +6
Computing the matter power spectrum, , as a function of cosmological parameters can be prohibitively slow in cosmological analyses, hence emulating this calculation is desira…
Evaluating the variance of individual halo properties in constrained cosmological simulations
Richard Stiskalek, Harry Desmond, Julien Devriendt +1
Constrained cosmological simulations play an important role in modelling the local Universe, enabling investigation of the dark matter content of local structures and their formati…
Optimal Inflationary Potentials
Tomás Sousa, Deaglan J. Bartlett, Harry Desmond +1
Inflation is a highly favoured theory for the early Universe. It is compatible with current observations of the cosmic microwave background and large scale structure and is a drive…
Marginalised Normal Regression: Unbiased curve fitting in the presence of x-errors
Deaglan Bartlett, Harry Desmond
The history of the seemingly simple problem of straight line fitting in the presence of both and errors has been fraught with misadventure, with statistically ad hoc and po…
Priors for symbolic regression
Deaglan J. Bartlett, Harry Desmond, Pedro G. Ferreira
When choosing between competing symbolic models for a data set, a human will naturally prefer the "simpler" expression or the one which more closely resembles equations previously…
On the fundamentality of the radial acceleration relation for late-type galaxy dynamics
Richard Stiskalek, Harry Desmond
Galaxies have been observed to exhibit a level of simplicity unexpected in the complex galaxy formation scenario posited by standard cosmology. This is particularly apparent in the…
No evidence for p- or d-wave dark matter annihilation from local large-scale structure
Andrija Kostić, Deaglan J. Bartlett, Harry Desmond
If dark matter annihilates into standard model particles with a cross-section which is velocity dependent, then Local Group dwarf galaxies will not be the best place to search for…
The underlying radial acceleration relation
Harry Desmond
The radial acceleration relation (RAR) of late-type galaxies relates their dynamical acceleration, , to that sourced by baryons alone, , across their ro…
On the functional form of the radial acceleration relation
Harry Desmond, Deaglan J. Bartlett, Pedro G. Ferreira
We apply a new method for learning equations from data -- Exhaustive Symbolic Regression (ESR) -- to late-type galaxy dynamics as encapsulated in the radial acceleration relation (…
