X-ray observations of dark matter dominated objects have the potential to reveal a signal from decaying or annihilating dark matter. We previously reported the detection of an unidentified emission line at 3.55 keV in the stacked XMM-Newton observations of galaxy clusters. The origin of this unidentified line could be attributed to decay of dark matter particles. I will provide a comprehensive review on the detections and non-detections of the 3.55 keV line in dark matter dominated objects in the literature.
