A NICERlook at the jet-like corona of MAXI J1535−571 through type-B quasi-periodic oscillation [PDF]
Monthly notices of the Royal Astronomical Society, 2023 MAXI J1535−571 is a black-hole X-ray binary that in 2017 exhibited a very bright outburst which reached a peak flux of up to 5 Crab in the 2–20 keV band. Given the high flux, several X-ray space observatories obtained unprecedented high signal-to-noise

On the energy dependence of the QPO phenomenon in the black hole system MAXI J1535-571 [PDF]
Monthly notices of the Royal Astronomical Society, 2022 Previous analysis of AstroSat observations of the black hole system MAXI J1535-571, have revealed the presence of a strong Quasi-Periodic Oscillation (QPO) whose frequency is correlated with the high energy spectral index.

Analysis of the reflection spectra of MAXI J1535-571 in the hard and intermediate states [PDF]
Monthly notices of the Royal Astronomical Society, 2022 We report results on the joint-fit of the NuSTAR and HXMT data for the black hole X-ray binary candidate MAXI J1535-571. The observations were obtained in 2017 when the source evolved through the hard, hard-intermediate and soft-intermediate states ...

The evolution of the corona in MAXI J1535-571 through type-C quasi-periodic oscillations with Insight-HXMT [PDF]
, 2022 Type-C quasi-periodic oscillations (QPOs) in black hole X-ray transients can appear when the source is in the low-hard and hard-intermediate states. The spectral-timing evolution of the type-C QPO in MAXI J1535-571 has been recently studied with Insight ...

MAXI J1535–571 2017 Outburst Seen by INTEGRAL/SPI and Investigating the Origin of Its Hard Tail [PDF]
Astrophysical Journal, 2022 On 2017 September 2 MAXI J1535–571 went into outburst and peaked at ∼5 Crab in the 2–20 keV energy range. Early in the flare, the INTErnational Gamma-Ray Astrophysics Laboratory (INTEGRAL) performed target of opportunity pointings and monitored the ...

Wavelet analysis of MAXI J1535-571 with Insight-HXMT [PDF]
, 2022 In this paper, wavelet analysis is used to study spectral-timing properties of MAXI J1535-571 observed by Insight-HXMT. The low-frequency quasi-periodic oscillations (QPOs) are detected in nine observations.

What training should psychiatrists have to interpret six- and 12-lead electrocardiograms?
BJPsych Bulletin, 2023 To monitor for drug-related cardiac arrhythmias, psychiatrists regularly perform and interpret 12-lead (12L) and, increasingly often, six-lead (6L) electrocardiograms (ECGs).
