Science of High Resolution X-ray Imaging
H. L. Marshall, K. Weaver, M. Schattenburg +34
This report summarizes potential studies of the Hi-ReX Science Analysis Group for an Ultra-High Angular Resolution X-ray Observatory. Many potential science cases are presented, sp…
Joint XMM-Newton and NuSTAR Observations of Type I X-ray Bursts from the Dipping Low-Mass X-ray Binary 4U 1323-62
Tugba Boztepe, Tolga Guver, Ersin Gogus +4
In this study, we report partly simultaneous XMM-Newton and NuSTAR observations of the bursting, dipping low mass X-ray binary, 4U 1323-62 obtained in 2024. 4U 1323-62 is one of th…
The 2025 outburst of IGR J17511-3057: timing and spectral insights from NICER and NuSTAR
A. Sanna, G. K. Jaisawal, T. E. Strohmayer +13
IGR J17511-3057 was observed in a new outburst phase starting in February 2025 and lasting at least nine days. We investigated the spectral and temporal properties of IGR J17511-30…
The 2020 Superburst of 4U 1608-522 and its impact on the accretion disk
Tugba Boztepe, Tolga Guver, Elif Ece Devecioglu +9
Superbursts are rare events observed from bursting neutron star low mass X-ray binaries. They are thought to originate from unstable burning of the thick layer of Carbon on the sur…
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…
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…
NICER observations of thermonuclear bursts from 4U 1728-34: Detection of oscillations prior to the onset of two bursts
Funda Bostanci, Tugba Boztepe, Tolga Guver +12
We present temporal and time-resolved spectral analyses of all the thermonuclear X-ray bursts observed from the neutron star low-mass X-ray binary (LMXB) 4U 1728-34 with NICER from…
Burst-Disk Interaction in 4U 1636-536 as observed by NICER
Tolga Guver, Funda Bostanci, Tugba Boztepe +10
We present the detection of 51 thermonuclear X-ray bursts observed from 4U 1636-536 by the Neutron Star Interior Composition Explorer (NICER) over the course of a three year monito…
Horizons: Nuclear Astrophysics in the 2020s and Beyond
H. Schatz, A. D. Becerril Reyes, A. Best +162
Nuclear Astrophysics is a field at the intersection of nuclear physics and astrophysics, which seeks to understand the nuclear engines of astronomical objects and the origin of the…
A NICER look at thermonuclear X-ray bursts from Aql X-1
Tolga Guver, Tugba Boztepe, David R. Ballantyne +8
We present spectral and temporal properties of all the thermonuclear X-ray bursts observed from Aql X-1 by the Neutron Star Interior and Composition Explorer (NICER) between 2017 J…
Thermonuclear X-ray Bursts with late secondary peaks observed from 4U 1608-52
Tolga Guver, Tugba Boztepe, Ersin Gogus +11
We report the temporal and spectral analysis of three thermonuclear X-ray bursts from 4U 1608-52, observed by the Neutron Star Interior Composition Explorer (NICER) during and just…
