A bstract We study the prediction for leptogenesis in two renormalizable supersymmetric SO(10) × 4 modular models which neutrino mass is dominantly generated by type I seesaw mechanism. The evolution of lepton asymmetries are described terms three-flavored density matrix equations three heavy Majorana neutrinos, where both vanishing initial condition and thermal right-handed neutrinos considere...

The accretion-powered millisecond pulsar IGR J00291+5934 underwent two ∼10 day long outbursts during 2008, separated by 30 days in quiescence. Such a short quiescent period between outbursts has never been seen before from a neutron star X-ray transient. X-ray pulsations at the 599 Hz spin frequency are detected throughout both outbursts. For the first time, we derive a pulse phase model that c...
