Insight-HXMT on-orbit thermal control status and thermal deformation impact analysis
The Hard X-ray Modulation Telescope is China’s first X-ray astronomy satellite launched on June 15, 2017, dubbed Insight-HXMT. Active and passive thermal control measures are employed to keep devices at suitable ...

Long-term evolution of the X-ray flux of the Crab pulsar
In order to carry out in-orbit calibration, the hard X-ray modulation telescope satellite (HXMT) has made a number of observations of Crab pulsar. We study the long-term evolution of the X-ray flux of the Crab...

Open AccessPossibility of traversable wormhole formation in the dark matter halo with istropic pressure
We explore the possibility of traversable wormhole formation in the dark matter halos. We obtain the exact solutions of the spherical symmetry traversable wormhole with isotropic pressure condition, based on t...

Reconstructing the cosmic expansion history up to redshift z=6.29 with the calibrated gamma-ray bursts
Recently, Gamma-Ray Bursts (GRBs) were proposed to be a complementary cosmological probe to type Ia supernovae (SNIa). GRBs have been advocated to be standard candles since several empirical GRB luminosity rel...
