Inversion of CHASE H Spectral Line during Solar Flares Based on RADYN Dataset via Deep Learning
W. Xu, Q. Hao, Z. Zheng +6
Solar flares represent one of the most intense forms of solar activity. Understanding the evolution of physical parameters in the solar atmosphere during flares is key to studying…
Exploring Space Weather From Young Solar-like Stars as Windows to Exoplanetary Habitability
V. S. Airapetian, K. Namekata, K. France +10
Young solar-like stars are efficient generators of magnetic activity, superflares, coronal mass ejections (CMEs), and stellar energetic particles. These phenomena drive the early e…
Testing the cosmological principle with the Pantheon+ sample and the region-fitting method
J. P. Hu, Y. Y. Wang, J. Hu +1
The cosmological principle is fundamental to the standard cosmological model. It assumes that the Universe is homogeneous and isotropic on very large scales. As the basic assumptio…
High-redshift cosmography: Application and comparison with different methods
J. P. Hu, F. Y. Wang
Cosmography is used in cosmological data processing in order to constrain the kinematics of the universe in a model-independent way. In this paper, we first investigate the effect…
Measuring cosmological parameters with a luminosity-time correlation of gamma-ray bursts
J. P. Hu, F. Y. Wang, Z. G. Dai
Gamma-ray bursts (GRBs), as a possible probe to extend the Hubble diagram to high redshifts, have attracted much attention recently. In this paper, we select two samples of GRBs th…
Measuring the fine structure constant on a white dwarf surface; a detailed analysis of Fe V absorption in G191-B2B
J. Hu, J. K. Webb, T. R. Ayres +12
The gravitational potential phi = GM/Rc^2 at the surface of the white dwarf G191-B2B is 10,000 times stronger than that at the Earth's surface. Numerous photospheric absorption fea…
Probing cosmic acceleration by strong gravitational lensing systems
Z. L. Tu, J. Hu, F. Y. Wang
Recently, some divergent conclusions about cosmic acceleration were obtained using type Ia supernovae (SNe Ia), with opposite assumptions on the intrinsic luminosity evolution. In…
Constraining the magnetic field on white dwarf surfaces; Zeeman effects and fine structure constant variation
J. Hu, J. K. Webb, T. R. Ayres +12
White dwarf atmospheres are subjected to gravitational potentials around times larger than occur on Earth. They provide a unique environment in which to search for any possi…
Testing the Distance-Duality Relation in the Universe
J. Hu, F. Y. Wang
In this paper, we test the cosmic distance duality (CDD) relation using the luminosity distances from joint light-curve analysis (JLA) type Ia supernovae (SNe Ia) sample and angula…
