Distance of PSR B0458+46 indicated by FAST HI absorption observations
W. C. Jing, J. L. Han, Tao Hong +6
The pulsar B0458+46 was previously believed to have a distance of about 1.3kpc and to be associated with a nearby supernova remnant, SNR HB9 (G160.9+2.6). We observe the neutral…
Distinct polarization properties for two emission states of four pulsars
Yi Yan, P. F. Wang, J. L. Han
Four pulsars, PSRs J1838+1523, J1901+0510, J1909+0007 and J1929+1844, are found to exhibit bright and weak emission states from sensitive FAST observations. New FAST observations h…
Strong and weak pulsar radio emission due to thunderstorms and raindrops of particles in the magnetosphere
X. Chen, Y. Yan, J. L. Han +14
Pulsars radiate radio signals when they rotate. However, some old pulsars often stop radiating for some periods. The underlying mechanism remains unknown, while the magnetosphere d…
More relaxed intracluster gas than galaxies in clusters in quasi-equilibrium
Z. S. Yuan, J. L. Han, H. Böhringer +2
During cluster mergers, the intracluster gas and member galaxies undergo dynamic evolution, but at different timescales and reach different states. We collect 24 galaxy clusters in…
Three New Spiral Galaxies with Active Nuclei Producing Double Radio Lobes
Xuyang Gao, Zhongsheng Yuan, Jinlin Han +2
Double radio lobes are generally believed to be produced by active nuclei of elliptical galaxies. However, several double-lobed radio sources have been solidly found to be associat…
Jiamusi pulsar observations: IV. The core-weak pattern of PSR B0329+54
Tao Wang, J. L. Han, C. Wang +2
The bright pulsar PSR B0329+54 was previously known for many years to have two emission modes. Sensitive observations of individual pulses reveal that the central component of puls…
