Spectral Properties of the Harary Signless Laplacian and Harary Incidence Energy

Mathematics
Let X be a partitioned matrix and let B its equitable quotient matrix. Consider a simple, undirected, connected graph G of order n. In this paper, we employ a technique based on quotient matrices derived from block-partitioned structures to establish new

Evolution of the Accretion Disk and Corona during the Outburst of the Neutron Star Transient MAXI J1807+132

The Astrophysical Journal
Low-mass X-ray binaries with a neutron star as the primary object show a complex array of phenomenology during outbursts. The observed variability in X-ray emission primarily arises from changes in the innermost regions of the accretion disk, neutron ...

Accretion Geometry of the New Galactic Black Hole Candidate AT2019wey in the Hard State

The Astrophysical Journal
We perform broadband spectral and timing studies of the Galactic low-mass black hole candidate AT2019wey using quasi-simultaneous NICER, Swift, and NuSTAR observations obtained in 2022.

Study on the construction of twisted cosine partially coherent beams and their propagation characteristics

AIP Advances
We propose a novel Schell model source for generating twisted partially coherent beams with an initial radius of curvature, which is called a twisted flat-topped cosine Gaussian Schell-model (TFCGSM) source.
