Return of 4U 1730–22 after 49 yr Silence: The Outburst Properties Observed by NICER and Insight-HXMT
The Astrophysical Journal Letters, 2022 After 49 yr of quiescence, 4U 1730–22 became active and had two outbursts in 2021 and 2022; the onset and tail of the outbursts were observed by NICER, which give us a peerless opportunity to study the state transition and its underlying mechanism.

A microservice-based portal for X-ray transient and variable sources [PDF]
, 2016 Modern soft X-ray observatories can yield unique insights into time domain astrophysics, and a huge amount of information is stored - and largely unexploited - in data archives. Like a treasure-hunt, the EXTraS project is harvesting the hitherto unexplored temporal domain information buried in the serendipitous data collected by the European Photon ...

Precession in transient X-ray sources [PDF]
Nature, 1975 THE origin of both the relatively long period and the transient nature of the recently discovered X-ray sources Ariel 1118−61 (ref. 1) and Ariel 0535+26 (ref. 2), with pulse periods of about 405 and 104 s, respectively, and decay times of days, is unclear. The pulse rate of A1118−61 has been attributed to an extremely short binary star orbital period3,

X-ray bursts from the galactic X-ray transient source GRS 1915+105 [PDF]
Advances in Space Research, 2001 We have analyzed publicly available RXTE/PCAs archival data of GRS 1915+105 during its burst/flaring state. The burst cycle ranges from 30 to 1300 s. These bursts are different from the type I and type II classical bursts seen in Low Mass X-ray Binaries (LMXBs) in terms of their temporal and spectral properties.

Discovery of a New X-Ray Transient Source in the Scutum Region with Suzaku [PDF]
Publications of the Astronomical Society of Japan, 2007 During an observation of the Galactic plane in the Scutum region with the Suzaku satellite, we discovered a new X-ray transient source, designated Suzaku J1844$-$0404. Compared with previous Chandra observations of the same field, four Chandra X-ray sources exist within the current positional uncertainty of Suzaku J1844$-$0404. A firm identification is

LINKING BURST-ONLY X-RAY BINARY SOURCES TO FAINT X-RAY TRANSIENTS [PDF]
The Astrophysical Journal, 2009 Burst-only sources are X-ray sources showing up only during short bursts but with no persistent emission (at least with the monitoring instrument which led to their discovery). These bursts have spectral characteristics consistent with thermonuclear (type I) burst from the neutron star surface, linking burst-only sources to neutron star X-ray binary ...

From mice to humans—divergent strategies for intestinal homeostasis and regeneration
FEBS Letters, EarlyView.Recent advances such as organoid genome editing, xenotransplantation, imaging, and whole‐genome sequencing have enabled direct studies of human intestinal stem cells (ISCs). These studies reveal species‐specific features, including slower ISC proliferation, distinct injury responses, slower somatic mutation accumulation in humans, and an inverse ...

The properties of discrete X-ray sources in star-forming galaxies [PDF]
, 2012 Observations of starburst galaxies have revealed a large number of point-like X-ray sources located within these systems, including active galactic nuclei (AGN), X-ray binaries (XRBs), and utraluminous X-ray sources (ULXs).
