A linear relation between galaxy-lensing cross-correlations to test the cosmological principle model-independently
Hai Yu, Pengjie Zhang, Jiaxin Wang +2
We discover a linear relation between two sets of galaxy-lensing cross-correlations. This linear relation holds, as long as light follows the geodesic and the metric is Friedmann-L…
hammurabi X: Simulating Galactic Synchrotron Emission with Random Magnetic Fields
Jiaxin Wang, Tess R. Jaffe, Torsten A. Enßlin +3
We present version X of the hammurabi package, the HEALPix-based numeric simulator for Galactic polarized emission. Improving on its earlier design, we have fully renewed the frame…
IMAGINE: A comprehensive view of the interstellar medium, Galactic magnetic fields and cosmic rays
Francois Boulanger, Torsten Ensslin, Andrew Fletcher +20
In this white paper we introduce the IMAGINE Consortium and its scientific background, goals and structure. Our purpose is to coordinate and facilitate the efforts of a diverse gro…
Inferring Galactic magnetic field model parameters using IMAGINE - An Interstellar MAGnetic field INference Engine
Theo Steininger, Torsten A. Enßlin, Maksim Greiner +7
Context. The Galactic magnetic field (GMF) has a huge impact on the evolution of the Milky Way. Yet currently there exists no standard model for it, as its structure is not fully u…
non-linear massive gravity and the cosmic acceleration
You Wu, Zu-Cheng Chen, Jiaxin Wang +1
Inspired by the non-linear massive gravity, we propose a new kind of modified gravity model, namely non-linear massive gravity, by adding the dRGT mass term reformula…
Detecting hidden uncertainties in standard candles and clocks via improved hypothesis test
Jiaxin Wang, Xinhe Meng
Tiny systematic uncertainty caused by cosmological hypotheses is hard to be detected, not only because the present observational errors are relatively large but also because hypoth…
Finding Possibility of Dynamical Dark Energy with Hubble Parameters
Jiaxin Wang, Xinhe Meng
The Hubble parameter is a critical measurement in cosmology, which contains the most direct information of the cosmic expansion history. Since discrepancy is found between low reds…
Energy transition in vacuum matter coupling
Jiaxin Wang, Xinhe Meng
The lately proposed vacuum matter coupling model (arXiv:1303.6568) seems to be able to provide solutions to a variety of problems in cosmology. This coupling expressed by a transit…
Phantom dark energy as an effect of bulk viscosity
Hermano Velten, Jiaxin Wang, Xinhe Meng
In a homogeneous and isotropic universe bulk viscosity is the unique viscous effect capable to modify the background dynamics. Effects like shear viscosity or heat conduction can o…
The distinctions between CDM and gravity according Noether symmetry
Han Dong, Jiaxin Wang, Xinhe Meng
Noether's theory offers us a useful tool to research the conserved quantities and symmetries of the modified gravity theories, among which the theory, a generally modified t…
Effects of New Viscosity Model on Cosmological Evolution
Jiaxin Wang, Xinhe Meng
Bulk viscosity has been intrinsically existing in the observational cosmos evolution with various effects for different cosmological evolution stages endowed with complicated cosmi…
