Unusual Emission Variations Near the Eclipse of A Black Widow PSR J17200533
S. Q. Wang, J. B. Wang, N. Wang +15
We report on an {unusually} bright observation of PSR J17200533 using the Five-hundred-meter Aperture Spherical radio Telescope (FAST). The pulsar is in a black widow system tha…
Long and Short Fast Radio Bursts are Different from Repeating and Non-repeating Transients
X. J. Li, X. F. Dong, Z. B. Zhang +1
We collect 133 Fast Radio Bursts (FRBs), including 110 non-repeating and 23 repeating ones, and systematically investigate their observational properties. To check the frequency de…
A repeating fast radio burst associated with a persistent radio source
C. -H. Niu, K. Aggarwal, D. Li +32
The dispersive sweep of fast radio bursts (FRBs) has been used to probe the ionized baryon content of the intergalactic medium, which is assumed to dominate the total extragalactic…
Kink oscillations of coronal loops
V. M. Nakariakov, S. A. Anfinogentov, P. Antolin +13
Kink oscillations of coronal loops, i.e., standing kink waves, is one of the most studied dynamic phenomena in the solar corona. The oscillations are excited by impulsive energy re…
A broadband radio study of PSR J0250+5854: the slowest-spinning radio pulsar known
C. H. Agar, P. Weltevrede, L. Bondonneau +19
We present radio observations of the most slowly rotating known radio pulsar PSR J0250+5854. With a 23.5 s period, it is close, or even beyond, the - diagram region tho…
Polarization properties of FRB 20201124A from detections with the 100-m Effelsberg Radio Telescope
G. H. Hilmarsson, L. G. Spitler, R. A. Main +1
The repeating FRB source, FRB 20201124A, was found to be highly active in March and April 2021. We observed the source with the Effelsberg 100-m radio telescope at 1.36 GHz on 9 Ap…
