Circular Polarization in two Active Repeating Fast Radio Bursts
Yi Feng, Yong-Kun Zhang, Di Li +5
Fast radio bursts (FRBs) are bright millisecond radio bursts at cosmological distances. Only a small fraction of FRBs apparently repeat. Polarization, a fundamental property of ele…
Exploring the single-pulse behaviours of PSR J0628+0909 with FAST
J. A. Hsu, J. C. Jiang, H. Xu +2
More than 100 rotating radio transients (RRATs) have been discovered since 2006. However, it is unclear whether RRATs radiate in the nulling states. PSR J0628+0909 has been classif…
Evolution of Spin Period and Magnetic Field of the Crab Pulsar: Decay of the Braking Index by the Particle Wind Flow Torque
Cheng-Min Zhang, Xiang-Han Cui, Di Li +8
The evolutions of a neutron star's rotation and magnetic field (B-field) have remained unsolved puzzles for over half a century. We ascribe the rotational braking torques of pulsar…
Using X-ray continuum-fitting to estimate the spin of MAXI J1305-704
Ye Feng, James F. Steiner, Santiago Ubach Ramirez +1
MAXI J1305-704 is a transient X-ray binary with a black hole primary. It was discovered on April 9, 2012, during its only known outburst. MAXI J1305-704 is also a high inclination…
A theoretical study of the time-lags due to Comptonization and the constraints on the X-ray corona in AGN
W. Zhang, I. E. Papadakis, M. Dovčiak +2
We study the Fourier time-lags due to the Comptonization of disc-emitted photons in a spherical, uniform, and stationary X-ray corona, which located on the rotational axis of the b…
Precession of magnetars: dynamical evolutions and modulations on polarized electromagnetic waves
Yong Gao, Lijing Shao, Gregory Desvignes +3
Magnetars are conjectured to be highly magnetized neutron stars (NSs). Strong internal magnetic field and elasticity in the crust may deform the stars and lead to free precession.…
Scattering variability detected from the circumsource medium of FRB 20190520B
S. K. Ocker, J. M. Cordes, S. Chatterjee +5
Fast radio bursts (FRBs) are millisecond-timescale radio transients, the origins of which are predominantly extragalactic and likely involve highly magnetized compact objects. FRBs…
First wide field-of-view X-ray observations by a lobster eye focusing telescope in orbit
C. Zhang, Z. X. Ling, X. J. Sun +75
As a novel X-ray focusing technology, lobster eye micro-pore optics (MPO) feature both a wide observing field of view and true imaging capability, promising sky monitoring with sig…
Prospects for Constraining the Yukawa Gravity with Pulsars around Sagittarius A*
Yiming Dong, Lijing Shao, Zexin Hu +2
The discovery of radio pulsars (PSRs) around the supermassive black hole (SMBH) in our Galactic Center (GC), Sagittarius A* (Sgr A*), will have significant implications for tests o…
The Interaction of Supernova 2018evt with a Substantial Amount of Circumstellar Matter -- An SN1997cy-like Event
Yi Yang, Dietrich Baade, Peter Hoeflich +29
A rare class of supernovae (SNe) is characterized by strong interaction between the ejecta and several solar masses of circumstellar matter (CSM) as evidenced by strong Balmer-line…
