This repository contains sample files, outputs, and analysis notebooks for a set of galaxy groups selected using UV absorption of Lyman Alpha, with follow-up observations by XMM-Newton.
The input sample file lives here, along with the region files necessary for analysing our XMM observations.
This should be everything necessary to recreate this analysis:
- sample_preparation.ipynb - A very simple notebook that simply changes the original Excel file into a csv, and plots the group's positions on the sky.
- get_xray_data.ipynb - Here we determine how much XMM data is available for these objects, download it, and process it into a scientifically usable state.
- visualisation/visualise_groups.ipynb - X-ray and X-ray/optical visualisations of the groups are created.
- visualisation/visualise_other_relevant_structures.ipynb - Other sources that we have identified as possibly being relevant have similar visualisations created.
-
lum_temp_rad_pipeline/running_LTR_pipeline.ipynb - We run a luminosity-temperature-radius pipeline to measure temperatures and luminosities within
$R_{500}$ and$R_{2500}$ , as well as the$R_{500}$ and$R_{2500}$ values themselves. - lum_temp_rad_pipeline/other_structures_running_LTR_pipeline.ipynb - Essentially the same as above, but for the other identified structures.
Contains anything generated and saved as part of this analysis, , e.g.:
- Source positions and redshifts
- Detection regions
- Figures
- Temperature and luminosities measured within overdensity radii
Output X-ray data products are not included because of storage limitations on GitHub.
