Supermassive Black Hole Mergers: Probing Gravitational Waves and Cosmology

Theoretical and Natural Science
The potential importance of supermassive black holes (SMBHs) in the centers of galaxies to the evolution of galaxies is known. As galaxies merge, their central SMBHs can become binary and eventually coalesce, emitting copious amounts of energy in the ...

Collider probes of baryogenesis with maximal CP asymmetry

Journal of High Energy Physics
We propose a novel collider probe of baryogenesis at TeV scale by measuring decay asymmetries into particle and anti-particle final states. Motivated by the idea of Dirac leptogenesis, we consider an extension of the standard model with new colored and ...

On the Lambda-evolution of galaxy clusters

European Physical Journal C: Particles and Fields, 2020
The evolution of galaxy clusters can be affected by the repulsion described by the cosmological constant. This conclusion is reached within the modified weak-field General Relativity approach where the cosmological constant $$\varLambda $$ Λ enables to ...

Sensitivity analysis of gamma spectroscopy system with dual high-purity germanium detectors

He jishu, 2022
BackgroundIn rare decay experiments, for instance dark matter and neutrino experiments, rays produced by the radioavtive decay in detector material induce extra experiment background, the energy deposition would contaminate the concerned region ...

Study of Various Dark Matter Halo Profiles in Milky Way and M31 Galaxies within the Standard Cosmology Framework [PDF]

Research in Astronomy and Astrophysics
In this paper, we study the rotation curves of the Milky Way galaxy and Andromeda galaxy (M31) by considering their bulge, disk, and halo components. We model the bulge region by the widely accepted de Vaucouleur’s law and the disk region by the well ...

Lightcone and quasi distribution amplitudes for light octet and decuplet baryons

Journal of High Energy Physics
We present a comprehensive investigation of leading-twist lightcone distribution amplitudes (LCDAs) and quasi distribution amplitudes (quasi-DAs) for light octet and decuplet baryons within large momentum effective theory.
