Gamma rays from dark matter spikes in EAGLE simulations - IMBH mock catalogue

DArk Matter SPIkes (DAMSPI) is a fully Python-based software for the analysis of dark matter spikes around Intermediate Mass Black Holes (IMBHs) in the Milky Way. It allows to extract an IMBH catalogue and their corresponding dark matter spike parameters from the EAGLE simulations in order to probe a potential gamma-ray signal from dark matter self-annihilation.  The dataset contains the IMBH catalogue including, among others, the coordinates, mass, formation redshift and spike parameters for each individual IMBH. Each column of the catalogue is described in detail in J. Aschersleben et al. (2024). We also provide separate files for which we calculated the gamma-ray fluxes for different dark matter masses and annihilation cross sections. Lastly, we provide a catalogue of our selection of Milky Way like galaxies within EAGLE. The columns of these files are also described in J. Aschersleben et al. (2024). The source code to extract this dataset is publicy available here: <div> <div> <pre><a href="https://doi.org/10.5281/zenodo.11488472">https://doi.org/10.5281/zenodo.11488472</a></pre> </div> </div> <h2>Description of the data files</h2> The imbh_catalogue/imbh/ directory contains the following files: <ol> <li>catalogue_nfw.h5</li> <li>catalogue_cored_gamma_0p3.h5</li> <li>catalogue_cored_gamma_0p9.h5</li> <li>catalogue_cored_gamma_free.h5</li> </ol> They contain the IMBH catalogues, including the coordinates and dark matter spike parameters, calculated assuming the 1.) NFW profile, 2.) cored profile with a fixed core index of 0.0, 3.) cored profile with a fixed core index of 0.4 and 4.) cored profile with the core index as a free fitting parameter. The imbh_catalogue/flux/<channel>/<energy_threshold>/ directory contains the gamma-ray fluxes of the IMBHs for a given annihilation channel, energy threshold, and dark matter mass. E.g. the imbh_catalogue/flux/b_channel/e_th_0.1GeV/m_dm_10.0GeV.h5 file contains the IMBH fluxes assuming the b-channel, an energy threshold of 0.1 GeV and a dark matter mass of 10 GeV. The IMBH fluxes are calculated for a variety of velocity weighted annihilation cross sections.  The imbh_catalogue/galaxy/ directory contains the mw_galaxies_catalogue_nfw.h5 file which contains our selection of Milky Way-like galaxies within EAGLE. The HDF files can be opened in Python with: <pre><code>import pandas as pd file_path = "<path_to_file>.h5" df = pd.read_hdf(file_path, key="table") # Printing the first few rows of the DataFrame print(df.head())</code><code> </code></pre>

Fig. 2 in Gamma Radiation Tolerance and Protein Carbonylation Caused by Irradiation of Resting Cysts in the Free-living Ciliated Protist Colpoda cucullus

Fig. 2. Analysis of proteins (Left panel) and protein carbonylation by ECL (Right panel) from non-irradiated and 4000 Gy irradiated cells. The samples in the lanes were from non-irradiated cells (NonIR), 4000 Gy irradiated cells (IR), and cells incubated for 12 h after 4000 Gy irradiation (IR incubated). The protein bands and ECL signals were measured and are shown in parentheses for each lane relative to the Non-IR sample.

Fig. 4. Relative viability of Colpoda vegetative cells, wet cysts, and dry cysts after gamma radiation doses of 0 (non-irradiated), 500, 1000, 2000, 3000, and 4000 Gy. The column heights and attached bars are the means and standard errors, respectively, of six measurements at each dose. Double asterisks indicate a significant difference at p <0.01 (Mann-Whitney U test).

The points and bars mark the means and standard errors, respectively, of six measurements at each dose. The excystment mean ± SE at 3, 6, 24, and 96 h after the induction of excystment is shown in (a), (b), (c), and (d), respectively. The column heights and attached bars in (a) to (d) are the means and standard errors, respectively, of six measurements at each dose. Asterisks and double asterisks indicate a significant difference at p <0.05 and p <0.01, respectively (Mann-Whitney U test).

Fig 1 in Flight ability and dispersal of European grapevine moth gamma-irradiated males (Lepidoptera: Tortricidae)

Fig 1. Schematic representation of the flight assessment cage used to measure the flight responses of Lobesia botrana males to calling females. In the female compartment, 2-day-old virgin females were confined inside a small cylindrical plastic mesh box with a 5% sucrose-wetted wick. Males irradiated either with 150 Gy or with 350 Gy and untreated males differentially marked with variously colored fluorescent powders were introduced into the male compartment. The number of males of each of the 3 kinds that flew through the open slit at the 45 cm height [the 2 lower openings (slits) were sealed] into the female compartment were recorded at 24, 48, 72 and 96 h. Air was drawn into the female compartment and exhausted from the male compartment.

The middle curve shows the corresponding results from the cross, TF × UM, however females irradiated with 200–300 Gy did not oviposit any eggs. The lower curve shows the corresponding results when both parents were irradiated.
