Sensitive Constraints on Coherent Radio Emission from Five Isolated White Dwarfs
Lei Zhang, Alexander Wolszczan, Joshua Pritchard +8
Coherent, periodic radio emission from pulsars has been widely interpreted as evidence of neutron stars as strongly magnetized compact objects. In recent years, radio pulses have a…
A Target Search for Fast Radio Bursts Associated with Two Fast Blue Optical Transients: AT2018cow and CSS161010
Shi-Jie Gao, Xiang-Dong Li, Yi-Xuan Shao +5
Fast blue optical transients (FBOTs) are luminous, rapidly evolving events with blue spectra, possibly powered by newborn magnetars and linked to fast radio bursts (FRBs). Given th…
Bright bursts with sub-millisecond structures of FRB 20230607A in a highly magnetized environment
DeJiang Zhou, J. L. Han, Bing Zhang +19
We report the observations of a repeating FRB 20230607A for 15.6 hours spanning 16 months using the Five-hundred-meter Aperture Spherical Radio Telescope (FAST) with the detection…
Tiny-Scale Properties within the Interstellar Medium towards PSR J16444559: I. Observational Evidence of Turbulence-induced Tiny Scale Atomic Structures
Mengting Liu, Di Li, J. R. Dawson +21
We investigated HI absorption toward a single pulsar, PSR J16444559, and its variability over timescales from days to years, using Murriyang, CSIRO's Parkes Radio Telescope. Our…
Probing Globular Cluster with MeerKAT and FAST: A Pulsar Polarization Census
Lei Zhang, Federico Abbate, Di Li +13
Only one globular cluster (GC), 47 Tuc, has been found to contain intracluster medium, with an electron density 100 times higher than that of the ISM in its vicinity. The character…
A 44-minute periodic radio transient in a supernova remnant
Di Li, Mao Yuan, Lin Wu +45
Long-period radio transients (LPTs) are a newly discovered class of radio emitters with periods ranging from minutes to hours. The astrophysical nature remains undetermined, partic…
Discovery of a millisecond pulsar associated with Terzan 6
Shi-Jie Gao, Yi-Xuan Shao, Pei Wang +6
Observations show that globular clusters might be among the best places to find millisecond pulsars. However, the globular cluster Terzan 6 seems to be an exception without any pul…
Polarization Characteristics of the Hyperactive FRB 20240114A
Jin-Tao Xie, Yi Feng, Di Li +14
Fast radio bursts (FRBs) are transient radio bursts of extragalactic origin characterized by millisecond durations and high luminosities. We report on observations of FRB 20240114A…
GTC optical/NIR upper limits and NICER X-ray analysis of SGR J1935+2154 for the outburst in 2022
Yi-Xuan Shao, Ping Zhou, Xiang-Dong Li +8
The Galactic magnetar SGR J1935+2154 has undergone another outburst since 2022 October 10. We present the results of searching for an optical/NIR counterpart of SGR J1935+2154 befo…
Scintillation velocity and arc observations of FRB 20201124A
Ziwei Wu, Weiwei Zhu, Bing Zhang +18
We present the scintillation velocity measurements of FRB~20201124A from the FAST observations, which reveal an annual variation. This annual variation is further supported by chan…
All-sky Guide Star Catalog for CSST
Hui-Mei Feng, Zi-Huang Cao, Man I Lam +17
The China Space Station Telescope (CSST) is a two-meter space telescope with multiple back-end instruments. The Fine Guidance Sensor (FGS) is an essential subsystem of the CSST Pre…
Upper limits on the radio pulses from magnetars and a central compact object with FAST
Wan-Jin Lu, Ping Zhou, Pei Wang +5
Magnetars and central compact objects (CCOs) are subgroups of neutron stars that show a number of properties distinguished from canonical radio pulsars. We performed radio observat…
Discovery and timing of pulsar J20163711 in supernova remnant CTB 87 with FAST
Qian-Cheng Liu, Wen-Juan Zhong, Yang Chen +4
We report on our discovery of the radio pulsar, PSR J20163711, in supernova remnant (SNR) CTB 87, with a significance of pulses, which confirms the compact nature of…
Plasma lensing interpretation of FRB 20201124A bursts at the end of September 2021
Xuechun Chen, Bin Hu, Pei Wang +3
When the radio photons propagate through a non-uniform electron density volume, the plasma lensing effect can induce an extreme magnification to the observed flux at certain freque…
A discovery of Two Slow Pulsars with FAST: "Ronin" from the Globular Cluster M15
Dengke Zhou, Pei Wang, Di Li +26
Globular clusters harbor numerous millisecond pulsars, but long-period pulsars ( ms) are rarely found. In this study, we employed a fast folding algorithm to analyze…
