New Features Relic densities: Relic densities can be computed for any object which implements thermal_cross_section(self, x) and has an attributed mx. For example: class ToyModel(object): def __init__(self, mx, sigmav): self.mx = mx self.sigmav = sigmav def thermal_cross_section(self, x): """ Compute the dark matter thermal cross section for a given ratio of mass to temperature. Parameters ---------- x: float DM mass over temperature. Returns ------- sigmav: float Dark matter thermal cross section. """ return self.sigmav model = ToyModel(10.313897683787216e3, 1.966877938634266e-15) relic_density(model, semi_analytic=True) # 0.12 Bug Fixes Fixed bugs in typos in scalar mediator widths Fixed bugs in typos in vector mediator widths Fixed bugs in typos in scalar mediator cross-sections Fixed bugs in typos in vector mediator cross-sections Closed Issues #4 : Adding relic densities #1 : Energy less than particles mass in hazma.rambo
