波暗物質與重力透鏡 Wave Dark Matter under the Lens
由軸子組成之波暗物質具有量子干涉特性。臺灣大學薛熙于教授和闕志鴻教授參與的國際團隊，發現背影星系在重力透鏡作用下的多重成像，與波暗物質模型的預測吻合，進而解決傳統冷暗物質的難題之一。
The manifestation of quantum interference between dark matter axions takes the form of waves (ψDM). An international team, comprising Prof. Hsi-Yu Schive and Prof. Tzihong Chiueh from NTU, shows that gravitational lensing leaves signatures in multiply lensed images of background galaxies in support of ψDM, which correctly predicts the level of flux anomalies remaining with the conventional cold dark matter lens models.
