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…
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…
Constraints on dark matter and astrophysics from tomographic -ray cross-correlations
Anya Paopiamsap, David Alonso, Deaglan J. Bartlett +1
We study the cross-correlation between maps of the unresolved -ray background constructed from the 12-year data release of the Fermi Large-Area Telescope, and the overdensity of…
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…
Modeling and testing screening mechanisms in the laboratory and in space
Valeri Vardanyan, Deaglan J. Bartlett
The non-linear dynamics of scalar fields coupled to matter and gravity can lead to remarkable density-dependent screening effects. In this short review we present the main classes…
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…
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 (…
