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…
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…
Reciprocating Magnetic Fields in the Pulsar Wind Observed from the Black Widow Pulsar J1720-0534
Chen-Chen Miao, Victoria Blackmon, Wei-Wei Zhu +41
We report the radio observations of the eclipsing black widow pulsar J1720-0534, a 3.26 ms pulsar in orbit with a low mass companion of mass 0.029 to 0.034 M. We obtain t…
Variability, polarimetry, and timing properties of single pulses from PSR J2222-0137 using FAST
X. L. Miao, W. W. Zhu, M. Kramer +14
In our work, we analyse single pulses from the recycled pulsar PSR J22220137 in one of its scintillation maxima observed by the Five-hundred-meter Aperture Spher…
X-ray hardening preceding the onset of SGR 1935+2154's radio pulsar phase
Pei Wang, Jian Li, Long Ji +32
Magnetars are neutron stars with extremely strong magnetic fields, frequently powering high-energy activity in X-rays. Pulsed radio emission following some X-ray outbursts have bee…
A radio pulsar phase from SGR J1935+2154 provides clues to the magnetar FRB mechanism
Weiwei Zhu, Heng Xu, Dejiang Zhou +34
The megajansky radio burst, FRB 20200428, and other bright radio bursts detected from the Galactic source SGR J1935+2154 suggest that magnetars can make fast radio bursts (FRBs), b…
High-altitude Magnetospheric Emissions from Two Pulsars
Mao Yuan, Weiwei Zhu, Michael Kramer +21
We discover three new weak pulse components in two known pulsars, one in PSR J0304+1932 and two in PSR J1518+4904. These components are emitted about half way between the main emis…
An extremely active repeating fast radio burst source in a likely non-magneto-ionic environment
Yi Feng, Di Li, Yong-Kun Zhang +24
Fast radio bursts (FRBs) are bright radio bursts originating at cosmological distances. Only three repeating FRBs FRB 20121102A, FRB 20190520B and FRB 20201124A among 60 kno…
