Limits to Extracting Neutron-Star Physics Constraints from NICER Pulse Profiles
Tolga Guver, Dimitrios Psaltis, Feryal Ozel +1
Modeling energy-dependent X-ray pulse profiles from rotation-powered millisecond pulsars observed with NICER has emerged as a promising avenue for measuring neutron star radii and…
On the Origin of Spectral Features Observed during Thermonuclear X-ray Bursts and in the Aftermath Emission of a Long Burst from 4U 1820-30
Gaurava K. Jaisawal, Jérôme Chenevez, Tod E. Strohmayer +6
We study 15 thermonuclear X-ray bursts from 4U 1820--30 observed with the Neutron Star Interior Composition Explorer (NICER). We find evidence of a narrow emission line at 1.0 keV…
A Comprehensive Study of Thermonuclear X-ray Bursts from 4U 1820-30 with NICER: Accretion Disk Interactions and a Candidate Burst Oscillation
Gaurava K. Jaisawal, Z. Funda Bostancı, Tuğba Boztepe +14
We present the results obtained from timing and spectral studies of 15 thermonuclear X-ray bursts from 4U 1820-30 observed with the Neutron Star Interior Composition Explorer (NICE…
Rapid Spectral Evolution of SGR 1935+2154 During its 2022 Outburst
Chin-Ping Hu, Zorawar Wadiasingh, Wynn C. G. Ho +9
During the 2022 outburst of SGR 1935+2154, a Fast-Radio-Burst-like event (FRB 20221014A) and X-ray activities occurred between two spin-up glitches, suggesting these glitches may c…
Timing and Spectral Evolution of the Magnetar 1E 1841-045 in Outburst
G. Younes, S. K. Lander, M. G. Baring +19
We present the timing and spectral analyses of the NICER, NuSTAR, and IXPE observations of the magnetar 1E 1841-045 covering 82 days following its August 2024 bursting activity as…
NICER Discovery that SRGA J144459.2-604207 is an Accreting Millisecond X-ray Pulsar
Mason Ng, Paul S. Ray, Andrea Sanna +17
We present the discovery, with the Neutron Star Interior Composition Explorer (NICER), that SRGA J144459.2-604207 is a 447.9 Hz accreting millisecond X-ray pulsar (AMXP), which und…
