论文摘要
暗物质模型可以根据其对星系特性的影响进行分类，包括冷暗物质（CDM），温暖的暗物质（WDM），自相互作用的暗物质（SIDM）和模糊的暗物质（FDM）。为了庆祝《愚人节》，以及冰岛2022年火山喷发爆发成立1周年，我们探索了新鲜的熔岩作为WDM的候选人。我们第一手验证了熔岩确实很温暖（在喷发结束后几个月表现出自由流，并保留温度，为1000k，将火放到草地上，可以感觉到自己的眉毛在4m的距离为4m），一旦与其生产源充分脱钩。
Dark matter models can be classified according to their impact on the properties of galaxies, including cold dark matter (CDM), warm dark matter (WDM), self-interacting dark matter (SIDM) and fuzzy dark matter (FDM). In celebration of April Fool's Day, and also of the 1-year anniversary of the start of the 2022 volcanic eruption at Fagradalsfjall here in Iceland, we explore fresh lava as a candidate for WDM specifically. We verify first hand that lava is indeed warm (exhibits free-streaming and retains temperature for several months after the eruption ends, is 1000K, sets fire to grass, can feel one's eyebrows singe at a distance of 4m) and dark once sufficiently decoupled from its source of production.
