| contents | What if the dark matter Sector is truly dark, self-interacting and unreachable by terrestrial experiments? How could we find hints of such dark sector if it is experimentally unreachable by any terrestrial experiment? We study a low-scale mirror Standard Model which can act as a model for dark matter, which interacts only gravitationally with the Standard Model particles. The mirror Standard Model sector particles are stable particles can comprise a measurable part of the dark matter of the Universe. These mirror Standard Model particles acquire mass through a low-temperature dark first order phase transition. We examine in detail this dark phase transition and we indicate how stochastic gravitational waves can be generated through this transition. For the model we use, the produced energy spectrum of the gravitational waves can be detected by the Square Kilometer Array. Moreover, we propose a possible way to detect effects of the particle nature of dark matter, using observational data coming from the guitar nebula, which can work if dark matter is collisional, so interacting dark matter. Without specifying a model for interacting dark matter, thus choosing an agnostic approach for interacting dark matter, we assume that the guitar nebula bow shock is generated by the interaction of the high speed neutron star that passes through the interstellar medium, which is assumed to be comprised by interacting dark matter and hydrogen. Our main proposal is that the opening angle of the bow shock can be directly related to the speed of sound of the dark matter particles, and a large angle of the bow shock could be a strong indicator that the interstellar medium is comprised by collisional dark matter and hydrogen gas. This is motivated by the Bosma effect. |
