Searches for Decaying Sterile Neutrinos with the X-Ray Quantum Calorimeter Sounding Rocket
Abstract
Rocket borne X-ray spectrometers can produce high-resolution spectra for wide field-of-view observations. This is useful in searches for dark matter candidates that produce X-ray lines in the Milky Way, such as decaying keV scale sterile neutrinos. In spite of exposure times and effective areas that are significantly smaller than satellite observatories, similar sensitivity to decaying sterile neutrinos can be attained due to the high spectral resolution and large field of view. We present recent results of such a search analyzing the telemetered data from the 2011 flight of the X-Ray Quantum Colorimeter instrument as well as ongoing progress in expanding the data set to include the more complete onboard data over additional flights.
