论文摘要
暗物质（DM）可以通过电子或/和光子的产生产生可观察的效果腐烂或消灭。这种概率被广泛研究了我们的银河系。在这里，我们考虑了仙女座星系相似效果的一个方面。我们明确估计了逆康普顿（IC）在光晕中散射电子的介质的光子的能量。这些光子可以通过不同的实验进行注册。暗物质歼灭或衰减可能是光环中高能电子的来源，尽管来源也可能是其他起源（例如，跑步中子星）。由于仙女座星系磁盘的空间方向（略微倾向于视线）的具体细节，因此对于仙女座halo的两个半球的光子，能量的差异可能会出现。可以获得这样的不对称性可以在几个10％的水平上。
Dark matter (DM) can give observable effects decaying or annihilating with production of electrons or/and photons. Such probability was widely researched for our Galaxy. Here we consider one aspect of similar effect for Andromeda galaxy. We explicitly estimate the energy of the photon of the medium experiencing Inverse Compton (IC) scattering off electron in halo. These photons can be registered by different experiments. Dark matter annihilation or decay could be the source of high energy electrons in halo, though the source could be of other origins too (e.g. running neutron stars). Because of specifics in space orientation of Andromeda galaxy disk (a little inclined to the line of sight), the difference in energies could arise for the photons from two hemispheres of Andromeda halo. It is obtained that such asymmetry can be at the level of several 10%.
