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.

Adaptive Semi-linear Inversion of Strong Gravitational Lens Imaging

Jammy2211/PyAutoLens 23 Dec 2014

In addition, we highlight the importance of data discretization in pixel-based inversion methods, showing that adaptive SLI averages over significant systematics that are present when a fixed source pixel grid is used.

Detecting the periodicity of highly irregularly sampled light-curves with Gaussian processes: the case of SDSSJ025214.67-002813.7

GAMES-UChile/mogptk 7 Mar 2022

Based on a 20-year-long multiband observation of its light-curve, it was conjectured that the quasar SDSSJ025214. 67-002813. 7 has a periodicity of ~4. 4 years.

Improving the background of gravitational-wave searches for core collapse supernovae: A machine learning approach

kstaats/karoo_gp 11 Feb 2020

Based on the prior O1-O2 observing runs, about 30% of the data collected by Advanced LIGO and Virgo in the next observing runs are expected to be single-interferometer data, i. e., they will be collected at times when only one detector in the network is operating in observing mode.

Recovering the star formation histories of recently-quenched galaxies: the impact of model and prior choices

bd-j/prospector 6 Jul 2022

Finally, we show that our new, public SFH model is able to accurately recover the properties of mock star-forming and quiescent galaxies and is suitable for broader use in the SED fitting community.
