Large-scale skymapping with COMPTEL using the full survey database presents challenging problems on account of the complex response and time-variable background. A new approach which attempts to address some of these problems is described, in which the information about each observation is preserved throughout the analysis. In this method, a maximum-entropy algorithm is used to determine image and background simultaneously. Because of the extreme computing requirements, the method has been implemented on a parallel computer, which brings large gains since the response computation is fully parallelizable. The zero level is left undetermined in this method. Results using data from 7 years of COMPTEL data are presented.

Neutrino lines and photon continua from cascade dark matter decay
In cascade dark-matter decay, neutrino-line searches can beat gamma-ray limits whenever the intermediate mediator is long-lived enough to suppress the photon flux.

Searching for Dark Matter with MeVCube
Using Fisher forecasting, the author shows that a 2U to 12U MeVCube CubeSat could probe new dark matter parameter space for evaporating primordial black holes and MeV-scale decaying or annihilating dark matter.
