Improved proper motion and gravity tests with PSR J1913+1102
Xueli Miao, Paulo C. C. Freire, Norbert Wex +11
PSR J1913+1102 is a highly asymmetric double neutron star system and an excellent laboratory for testing scalar-tensor gravity theories, as well as a potential progenitor analogue…
The double neutron star PSR J1946+2052 I. Masses and tests of general relativity
Lingqi Meng, Paulo C. C. Freire, Kevin Stovall +28
We conducted high-precision timing of PSR J1946+2052 to determine the masses of the two neutron stars in the system, test general relativity (GR) and assessed the system's potentia…
Single-pulse-based interstellar scintillation studies of RRATs
Zi-wei Wu, Wei-wei Zhu, Zi-yao Fang +16
The nature of irregularly spaced pulses of rotating radio transients (RRATs) complicates interstellar scintillation studies. In this letter, we report the primary scintillation par…
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…
Sudden polarization angle jumps of the repeating fast radio burst FRB 20201124A
J. R. Niu, W. Y. Wang, J. C. Jiang +41
We report the first detection of polarization angle (PA) orthogonal jumps, a phenomenon previously only observed from radio pulsars, from a fast radio burst (FRB) source FRB 202011…
The Relativistic Spin Precession in the Compact Double Neutron Star System PSR~J1946+2052
Lingqi Meng, Weiwei Zhu, Michael Kramer +16
We observe systematic profile changes in the visible pulsar of the compact double neutron star system PSR~J1946+2052 using observations with the Five-hundred-meter Aperture Spheric…
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…
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…
Arecibo and FAST Timing Follow-up of twelve Millisecond Pulsars Discovered in Commensal Radio Astronomy FAST Survey
C. C. Miao, W. W. Zhu, D. Li +46
We report the phase-connected timing ephemeris, polarization pulse profiles, Faraday rotation measurements, and Rotating-Vector-Model (RVM) fitting results of twelve millisecond pu…
Frequency-dependent polarization of repeating fast radio bursts-implications for their origin
Yi Feng, Di Li, Yuan-Pei Yang +23
The polarization of fast radio bursts (FRBs), bright astronomical transients, contains crucial information about their environments. We report polarization measurements of five rep…
