X-ray and Radio Monitoring of the Neutron Star Low Mass X-ray Binary 1A 1744-361: Quasi Periodic Oscillations, Transient Ejections, and a Disk Atmosphere
Mason Ng, Andrew K. Hughes, Jeroen Homan +19
We report on X-ray (NICER/NuSTAR/MAXI/Swift) and radio (MeerKAT) timing and spectroscopic analysis from a three-month monitoring campaign in 2022 of a high-intensity outburst of th…
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…
A catalogue of unusually long thermonuclear bursts on neutron stars
Khaled Alizai, Jérôme Chenevez, Andrew Cumming +10
Rare, energetic (long) thermonuclear (Type I) X-ray bursts are classified either as intermediate-duration or superbursts, based on their duration. Intermediate-duration bursts last…
Thermonuclear Type-I X-ray Bursts and Burst Oscillations from the Eclipsing AMXP Swift J1749.4-2807
A. C. Albayati, P. Bult, D. Altamirano +10
Swift J1749.4-2807 is the only known eclipsing accreting millisecond X-ray pulsar. In this paper, we report on 7 thermonuclear (Type-I) X-ray bursts observed by NICER during its 20…
Probing spectral and timing properties of the X-ray pulsar RX J0440.9+4431 in the giant outburst of 2022-2023
Manoj Mandal, Rahul Sharma, Sabyasachi Pal +10
The X-ray pulsar RX J0440.9+4431 went through a giant outburst in 2022 and reached a record-high flux of 2.3 Crab, as observed by Swift/BAT. We study the evolution of different spe…
Detection of millihertz quasi-periodic oscillations in the low-mass X-ray binary 4U 1730--22 with NICER
G. C. Mancuso, D. Altamirano, P. Bult +8
We report the discovery of millihertz quasi-periodic oscillations (mHz QPOs) from the neutron star (NS) low-mass X-ray binary 4U 1730--22 using the Neutron Star Interior Compositio…
On the cyclotron absorption line and evidence of the spectral transition in SMC X-2 during 2022 giant outburst
G. K. Jaisawal, G. Vasilopoulos, S. Naik +7
We report comprehensive spectral and temporal properties of the Be/X-ray binary pulsar SMC X-2 using X-ray observations during the 2015 and 2022 outbursts. The pulse profile of the…
GRB 221009A: Discovery of an Exceptionally Rare Nearby and Energetic Gamma-Ray Burst
Maia A. Williams, Jamie A. Kennea, S. Dichiara +53
We report the discovery of the unusually bright long-duration gamma-ray burst (GRB), GRB 221009A, as observed by the Neil Gehrels Swift Observatory (Swift), Monitor of All-sky X-ra…
