We report on the deep observations of the “bursting pulsar” GRO J1744–28, which were performed with XMM-Newton and aimed to clarify the origin of its X-ray emission in quiescence. We detect the source at a luminosity level of ∼1034 erg s−1 with an X-ray spectrum that is consistent with the power law, blackbody, or accretion-heated neutron star atmosphere models. The improved X-ray localization of the source allowed us to confirm the previously identified candidate optical counterpart as a…

Modelling spin-up episodes in accreting millisecond X-ray pulsars
Accreting millisecond X-ray pulsars are known to provide a wealth of physical information during their successive states of outburst and quiescence. Based on the observed spin-up and spin-down

A Chandra Observation of GRO J1744–28: The Bursting Pulsar in Quiescence
We present a Chandra/Advanced CCD Imaging Spectrometer I-array observation of GRO J1744-28. We detected a source at a position of R.A. = 17h44m3309, decl. = -28°44'270 (J2000.0; with a 1 σ error of
GRO J1744−28: an intermediate B-field pulsar in a low-mass X-ray binary
The bursting pulsar, GRO J1744-28, went again in outburst after $\sim$18 years of quiescence in mid-January 2014. We studied the broad-band, persistent, X-ray spectrum using X-ray data from a
HIGH-RESOLUTION X-RAY SPECTROSCOPY OF THE BURSTING PULSAR GRO J1744-28
The bursting pulsar GRO J1744-28 is a Galactic low-mass X-ray binary that distinguishes itself by displaying type-II X-ray bursts: brief, bright flashes of X-ray emission that likely arise from
Evidence for the radiation-pressure dominated accretion disk in bursting pulsar GRO J1744−28 using timing analysis
The X-ray pulsar GRO J1744−28 is a unique source that shows both pulsations and type-II X-ray bursts, allowing studies of the interaction of the accretion disk with the magnetosphere at huge
Discovery of hard X-ray pulsations from the transient source GRO J1744 – 28
AN UNUSUAL astronomical source of hard X-ray bursts, GRO J1744 – 28, was discovered recently1,2. The properties of this source differ markedly from those of other known high-energy burst
ASCA Observations of GRO J1744–28
We report the ASCA results of the bursting X-ray pulsar GRO J1744-28, which was observed in 1996 February and 1997 March. The source flux in the 2-10 keV band was 2.0 × 10-8 ergs s-1 cm2 in 1996 and
Study of the accretion torque during the 2014 outburst of the X-ray pulsar GRO J1744‑28
We present the spectral and timing analysis of the X-ray pulsar GRO J1744-28 during its 2014 outburst using data collected with the X-ray satellites Swift, INTEGRAL, Chandra, and XMM-Newton. We
The Nature and Evolutionary History of GRO J1744-28
GRO J1744-28 is the first known X-ray source to display bursts, periodic pulsations, and quasi-periodic oscillations. This source may thus provide crucial clues that will lead to an understanding of
XMM-Newton observation of the bursting pulsar GRO J1744-28 in quiescence
TLDR
The XMM-Newton X-ray observatory makes the first detection of GRO J1744-28 in its quiescent state at a position which is consistent with previous high-energy positions (but not consistent with a proposed IR counterpart).
ROSAT position of the transient bursting pulsar GRO J1744-28 and identification of its near-infrared counterpart
We report the detection with ROSAT of a transient X-ray source at R.A. 17h44m331 and decl. -28°44'29'' (J2000), which we identify with the transient bursting pulsar GRO J1744-28. We have made K-band
