Induced Representations of the Two Parametric Quantum Deformation U$_{pq}$[gl(2/2)]

, 2000
The two-parametric quantum superalgebra $U_{p,q}[gl(2/2)]$ and its induced representations are considered. A method for constructing all finite-dimensional irreducible representations of this quantum superalgebra is also described in detail. It turns out

A Universal Break in Energy Functions of Three Hyperactive Repeating Fast Radio Bursts

The Astrophysical Journal Letters
Fast radio bursts (FRBs) are millisecond-duration pulses occurring at cosmological distances with a mysterious origin. Observations show that at least some FRBs are produced by magnetars. All magnetar-powered FRB models require some triggering mechanisms,

Bumpy Superluminous Supernovae Powered by a Magnetar–Star Binary Engine

The Astrophysical Journal Letters
Wolf–Rayet stars in close binary systems can be tidally spun up by their companions, potentially leaving behind fast-spinning, highly magnetized neutron stars, known as “magnetars,” after core collapse.

An Occultation Event in Centaurus A and the Clumpy Torus Model

, 2011
We have analyzed 16 months of sustained monitoring observations of Cen A from the Rossi X-ray Timing Explorer to search for changes in the absorbing column in the line of sight to the central nucleus. We present time-resolved spectroscopy which indicates
