A tomographic test of cosmological principle using the JLA compilation of type Ia supernovae
Zhe Chang, Hai-Nan Lin, Yu Sang +1
We test the cosmological principle by fitting a dipolar modulation of distance modulus and searching for an evolution of this modulation with respect to cosmological redshift. Base…
Local probes strongly favor CDM against power-law and universe
Hai-Nan Lin, Xin Li, Yu Sang
We constrain three cosmological models, i.e. the concordance cold dark matter plus a cosmological constant (CDM) model, Power-law (PL) model, and model using the availa…
Testing the distance duality relation using type Ia supernovae and ultracompact radio sources
Xin Li, Hai-Nan Lin
We test the possible deviation of the cosmic distance duality relation using the standard candles/rulers in a fully model-independent manner. Type-Ia…
Testing the anisotropy of the Universe with the distance duality relation
Xin Li, Li Tang, Hai-Nan Lin
The distance duality relation (DDR) is valid in Riemannian spacetime. The astronomical data hint that the universe may have certain preferred direction. If the universe is describe…
Finslerian dipolar modulation of the CMB power spectra at scales
Xin Li, Hai-Nan Lin
A common explanation for the CMB power asymmetry is to introduce a dipolar modulation at the stage of inflation, where the primordial power spectrum is spatially varying. If the un…
Spatial and temporal variations of the fine-structure constant in the Finslerian universe
Xin Li, Hai-Nan Lin
Recent observations show that the electromagnetic fine-structure constant, , may vary with space and time. In the framework of Finsler spacetime, we propose here an anisotropi…
Scale-invariance in soft gamma repeaters
Zhe Chang, Hai-Nan Lin, Yu Sang +1
The statistical properties of the soft gamma repeater SGR J1550--5418 are investigated carefully. We find that the cumulative distributions of fluence, peak flux and duration can b…
