NICER detection of a new candidate cyclotron line in the bursting X-ray pulsar GRO J1744-28
Qi Liu, Lingda Kong, Long Ji +15
We report the detection of cyclotron resonant scattering features (CRSFs) in the spectrum of the unique bursting pulsar GRO J1744-28, observed during its recent outburst in 2021 wi…
Rapid quasi-periodic reconfiguration of the accretion column in pulsar 1A 0535+262
Lingda Kong, Xiaohang Dai, Andrea Santangelo +12
Accretion onto strongly magnetized neutron stars is commonly interpreted using quasi-steady models, in which the accretion-column structure adjusts smoothly to the mass inflow rate…
Probing the emission geometry of the X-ray pulsar 2S 1417624 during a weak outburst with NICER, IXPE, and NuSTAR
Menglei Zhou, Pengju Wang, Honghui Liu +12
We report results from a multi-mission observational campaign of the transient X-ray pulsar 2S~1417624 during its 2025 outburst, using data from NICER, IXPE, and NuSTAR. Phase-a…
Timing and spectral variability in 2S 1417-624 observed with Insight-HXMT
Qi Liu, Lingda Kong, Can Güngör +5
We present the results of the spectral and timing analyses of the accreting X-ray pulsar, 2S 1417-624, during the 2018 and 2021 outbursts with Insight-HXMT. We find that the pulse…
Temporal and spectral variations of the X-ray pulsar Cen X-3 observed by NuSTAR
Qi Liu, Wei Wang, Andrea Santangelo +3
We report a time-resolved analysis of the accreting X-ray pulsar Cen X-3 using observations carried out by NuSTAR, which cover approximately two binary orbits in different intensit…
Evidence for a nearly orthogonal rotator in GX 301--2 with phase-resolved cyclotron resonant scattering features
Xiao Chen, Yuanze Ding, Wei Wang +8
Cyclotron resonant scattering features (CRSFs) are the absorption features in the X-ray spectra of strongly magnetized accretion neutron stars (NSs), which are probably the most re…
