A Cyclic Burst Rate Behavior of a Persistent X-ray Burster: Recent XMM-Newton and NuSTAR Observations of 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…
