NICER Magnetar Burst Catalog
Che-Yen Chu, Chin-Ping Hu, Teruaki Enoto +13
In this paper, we present a comprehensive catalog of short bursts from magnetars based on eight years of NICER observations. A total of 1130 bursts were identified from 14 sources,…
Revisiting the unification of tidal disruption events with polarimetry
H. C. I. Wichern, G. Leloudas, M. Pursiainen +10
Tidal disruptions of stars by supermassive black holes produce multi-wavelength emission, of which the optical emission is of ambiguous origin. A unification scenario of tidal disr…
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 multiwavelength study of the Galactic center black hole candidate MAXI J1744-294
Shifra Mandel, Kaya Mori, Paul A. Draghis +37
For the first time in nearly a decade, a bright transient was detected in the central parsec (pc) of the Galaxy. MAXI J1744-294, or -- as it was known in its previous life -- Swift…
Photospheric radius expansion thermonuclear burst and X-ray reflection from the neutron star X-ray binary 4U 1702-429
Manoj Mandal, Sachindra Naik, Gaurava Kumar Jaisawal
We perform a comprehensive study of thermonuclear bursts from the neutron star low-mass X-ray binary 4U 1702-429 detected with NICER and XMM-Newton. The thermonuclear burst detecte…
Detection of low-luminosity X-ray pulsations from the accreting millisecond pulsar IGR J17511-3057: An ever-thinning thread between bright accretion and sub-luminous states
Giulia Illiano, Alessandro Papitto, Sergio Campana +14
After nearly a decade in quiescence, the accreting millisecond pulsar IGR J175113057 displayed a new outburst on 2025 February 11, its third since discovery, following previous…
Broadband study of the SMC pulsar RX J0032.9-7348 during its X-ray brightening in 2024
Birendra Chhotaray, Gaurava K. Jaisawal, Sachindra Naik +1
We present the results of the broadband timing and spectral analysis of the poorly understood SMC pulsar RX J0032.9-7348 (= SXP 7.02) using NuSTAR and NICER observations during its…
Probing thermonuclear bursts and X-ray reflection features in Aql X-1 during 2024 outburst
Manoj Mandal, Sabyasachi Pal, G. K. Jaisawal +3
We report the broadband timing and spectral properties of the neutron star low-mass X-ray binary Aql X-1 during the 2024 outburst with NICER, NuSTAR, and Swift observatories. We de…
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…
