We report the first detection of a linear correlation between rms variability amplitude and flux
in the ultraluminous X-ray source (ULX) NGC 5408 X-1. The rms–flux relation has …

We present results from a study of short-term variability in 19 archival observations by XMM–Newton
of 16 ultraluminous X-ray sources (ULXs). Eight observations (six sources) showed …

We have investigated the short-term linear relation between the rms variability and the flux
in 1961 observations of nine black hole X-ray binaries. The rms–flux relation for the 1–10 Hz …

We present an analysis of the short time-scale variations in the properties of the strong (type
‘C’) quasi-periodic oscillation (QPO) observed in XTE J1550−564 during its 1998 outburst. …

The Southern Ocean is disproportionately important in its effect on the Earth system, impacting
climatic, biogeochemical, and ecological systems, which makes recent observed changes …

Ultraluminous X-ray sources (ULXs) with luminosities lying between ∼3 � 10 39 and 2 � 10
40 erg s −1 represent a contentious sample of objects as their brightness, together with a …

Online assessment is defined as a systematic method of gathering information about a
learner and learning processes to draw inferences about the learner's dispositions. Online …

… We used 3200 s segments for the XMM–Newton observations and 12 800 s segments for
the Chandra observations. The greater length of the Chandra observations allows us to probe …
