EXPO: a quantum leap in fast, wide-band X-ray polarimetry for astrophysics
Paolo Soffitta, Sebastien Guillot, Ian Hutchinson +137
The Enhanced X-ray Polarimetry Observatory (EXPO) is a mission concept proposed to ESA as an M8 candidate, with a prospective launch in 2041. Building on the scientific success of…
Detection of Oscillations in a Type I X-Ray Burst of 4U 0614+091 with SVOM/ECLAIRs
Sébastien Le Stum, Floriane Cangemi, Alexis Coleiro +29
On 2025 January 10, a thermonuclear (Type I) X-ray burst from the neutron star low-mass X-ray binary \textit{4U~0614+091} was detected with the ECLAIRs instrument on board the \tex…
Observatory Science with eXTP
Ping Zhou, Jirong Mao, Liang Zhang +97
Scheduled for launch in 2030, the enhanced X-ray Timing and Polarization (eXTP) telescope is a Chinese space-based mission aimed at studying extreme conditions and phenomena in ast…
Dense Matter in Neutron Stars with eXTP
Ang Li, Anna L. Watts, Guobao Zhang +82
In this White Paper, we present the potential of the enhanced X-ray Timing and Polarimetry (eXTP) mission to constrain the equation of state of dense matter in neutron stars, explo…
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, TuÄba 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…
