Supplementaries - Secondary emission spectra for Heavy WIMPs

The uploads contain the following material: Paper.zip - The figures from the paper are provided here. Secondary_emission_numeric_data_mass_channel_Einasto_core.zip - The secondary emission (Synchrotron + IC) numeric data in txt. files with Energy axis (in eV) and total flux (in erg/cm2/s) for three WIMP annihilation channels (W, b, and tau) and for the WIMP masses of 1, 10, 100 and 1000 TeV/c2. Two cases of DM density profiles are considered- a cuspy Einasto profile (10pc core radius) and a cored Einasto (1kpc core radius) distribution. Spatial_flux_bands.zip - The numeric data and figures showing the expected secondary emission fluxes in 1 deg angular bands around the Galactic Centre (up to 7 deg) are provided for all cases of WIMP mass, channel, and density profiles as mentioned in Pt. 2 Total_emission.zip - This includes the numeric data and figures considering both the prompt emission and secondary emission for the different cases as mentioned in Pt. 2. Files named as data_mass_channel_core_radius. Single_zone_vs_3D_approach.zip - Shows a comparison of this work with the methodology used in Djuvsland et al. (2023) (single-zone approach). A figure showing the comparison with radio emission expected from near the Galactic Centre is also provided. Validation_checks.zip - The robustness of this work under different resolutions of the simulation setup is presented by showing the output for 49, 121 (default) and 441 grid points (i.e., number of columns) in X-Y. A figure shows the fraction of secondary emission luminosity (as high as 45 %) to the total emission (IC+Synchrotron+ prompt emission). With a more realistic 3D spatial modelling approach in the current work, the IC luminosity fraction reduces, but is still significant, as shown with the comparison figures. Furthermore, the secondary radiation output under different scenarios of external radiation and magnetic fields is presented in another figure. Also provided are figures validating the similarity between PPPC and HDM calculation obtained fluxes (considering the single-zone approach). Note that all the remaining results mentioned here use HDM calculations. We considered a cuspy Einasto profile for simulating most of the results. GC_environment.zip - Includes some example figures showing the magnetic field strength (in micro Gauss) and radiation field (in cm-3 erg-1) distribution across the Z axis for some X-Y positions. These are the field strength values used in the 'simulation columns' for computing IC and Synchrotron radiation.
