NICER Discovers Spectral Lines During Photospheric Radius Expansion Bursts from 4U 1820-30: Evidence for Burst-driven Winds
T. E. Strohmayer, D. Altamirano, Z. Arzoumanian +14
We report the discovery with the Neutron Star Interior Composition Explorer (NICER) of narrow emission and absorption lines during photospheric radius expansion (PRE) X-ray bursts…
Discovery of Soft X-ray Pulsations from PSR J1231-1411 using NICER
Paul S. Ray, Sebastien Guillot, Scott M. Ransom +10
We report the discovery of soft X-ray pulsations from the nearby millisecond pulsar PSR J12311411 using NICER. The pulsed emission is characterized by a broad and asymmetric mai…
NICER Observations of the 2018 Outburst of XTE J1810-197
Tolga Guver, Ersin Gogus, Eda Vurgun +9
We present the earliest available soft X-ray observations of XTE J1810-187, the prototypical transient magnetar, obtained 75--84 days after its 2018 outburst with the Neutron Star…
Probing the stellar wind environment of Vela X-1 with MAXI
C. Malacaria, T. Mihara, A. Santangelo +4
Vela X-1 is among the best studied and most luminous accreting X-ray pulsars. The supergiant optical companion produces a strong radiatively-driven stellar wind, which is accreted…
