用中子星探测暗物质

Detecting Dark Matter with Neutron Stars

Anupam Ray

AI总结:

该研究利用中子星作为天体物理实验室,通过引力波非探测和热观测来约束重且不湮灭的暗物质与核子的相互作用,提供比直接探测实验更强的限制。

摘要:

中子星为探测暗物质的性质提供了强大的天体物理实验室。重且不湮灭的暗物质在中子星中逐渐积累,可导致形成质量相当的(中等质量)黑洞,而未能探测到此类低质量黑洞并合产生的引力波,可以约束此类暗物质与核子的相互作用。这些约束虽然依赖于目前尚不确定的双中子星并合率密度,但比直接探测实验的约束要严格得多,并为重且不湮灭的暗物质相互作用提供了一些最强的限制。此外,具有重子数破坏相互作用的暗物质可诱导冷中子星产生额外热量,因此受到冷中子星热观测的显著约束。

英文摘要:

Neutron stars offer powerful astrophysical laboratories to probe the properties of dark matter. Gradual accumulation of heavy, non-annihilating dark matter in neutron stars can lead to the formation of comparable-mass black holes, and non-detection of gravitational waves from mergers of such low-mass black holes can constrain such dark matter interactions with nucleons. These constraints, though dependent on the currently uncertain binary neutron star merger rate density, are significantly more stringent than those from direct detection experiments and provide some of the strongest limits on heavy, non-annihilating dark matter interactions. Additionally, dark matter with baryon number-violating interactions can induce excess heating in cold neutron stars and is thus significantly constrained by thermal observations of cold neutron stars.
