The buildup of galaxies and their spheroids: the contributions of mergers, disc instabilities and star formation

swiftsim/swiftsim 14 Jul 2022

Disc instabilities and their associated starbursts dominate for intermediate-mass spheroids ($10^{8. 5}<M_\mathrm{*, sph}<10^{11}$ M$_\odot$) at $z=0$.

Modelling DSA, FAST and CRAFT surveys in a z-DM analysis and constraining a minimum FRB energy

frbs/zdm 9 Aug 2024

This work follows from previous redshift-dispersion measure ($z$-DM) analyses in which we model instrumental biases and simultaneously fit population parameters and cosmological parameters to the observed population of FRBs.

Galaxies and Halos on Graph Neural Networks: Deep Generative Modeling Scalar and Vector Quantities for Intrinsic Alignment

georgestein/ml-in-cosmology 14 Apr 2022

As the details of galaxy formation and evolution relevant to IA cannot be simulated in practice on such volumes, we propose as an alternative a Deep Generative Model.

PyAutoLens: Open-Source Strong Gravitational Lensing

Jammy2211/PyAutoLens 2 Jun 2021

Strong gravitational lensing, which can make a background source galaxy appears multiple times due to its light rays being deflected by the mass of one or more foreground lens galaxies, provides astronomers with a powerful tool to study dark matter, cosmology and the most distant Universe.

Mapping stellar surfaces III: An Efficient, Scalable, and Open-Source Doppler Imaging Model

rodluger/showyourwork 12 Oct 2021

It is also critical to the detection and characterization of extrasolar planets, in particular those targeted in extreme precision radial velocity (EPRV) searches, which must contend with stellar variability that is often orders of magnitude stronger than the planetary signal.
