Multi-Messenger Milky Way

A plot inspired by NASA's Multiwavelength Milky Way plot, that also shows the recent observations of neutrinos from the galactic plane by the IceCube Neutrino Observatory. Some updated datasets are included compared to the original NASA plot, notably the Fermi LAT all-sky survey. The data for the latter is included in the subdirectory preprocessed_data, and was preprocessed from ~250 GB of Fermi LAT data of two years of observation time.

Note: The scripts and plot are still a work in progress and as such subject to change.

Usage

Install the mamba environment that contains all the necessary packages using

$ mamba env create -f environment.yml

An installation of miniforge is recommended. Additionally, make sure that make and unzip are installed. To download the data files run

$ make download

After all files are downloaded, you can build the plot using make all or

$ make build/multi_messenger.pdf

The plot can be found in the build directory.
