The comptonizing medium of the black-hole X-ray binary MAXI J1535−571 through type-C quasi-periodic oscillations [PDF]

open access: yesMonthly notices of the Royal Astronomical Society, 2023
We present a detailed spectral and temporal analysis of the black-hole candidate MAXI J1535−571 using NICER observations in September and October 2017.

A NICERlook at the jet-like corona of MAXI J1535−571 through type-B quasi-periodic oscillation [PDF]

open access: yesMonthly 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

A Spectral-timing Study of the Inner Flow Geometry in MAXI J1535-571 with Insight-HXMT and NICER [PDF]

open access: yesAstrophysical Journal, 2023
We have performed a spectral-timing analysis of the black hole X-ray binary MAXI J1535-571 during its 2017 outburst, with the aim of exploring the evolution of the inner accretion flow geometry.

On the energy dependence of the QPO phenomenon in the black hole system MAXI J1535-571 [PDF]

open access: yesMonthly 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.

Wavelet analysis of the transient QPOs in MAXI J1535−571 with Insight-HXMT [PDF]

open access: yesMonthly notices of the Royal Astronomical Society, 2022
Using wavelet analysis and power density spectrum, we investigate two transient quasi-periodic oscillations (QPOs) observed in MAXI J1535−571 observed with Insight-HXMT.

Analysis of the reflection spectra of MAXI J1535-571 in the hard and intermediate states [PDF]

open access: yesMonthly 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]

open access: yes, 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 ...

Wavelet analysis of MAXI J1535-571 with Insight-HXMT [PDF]

open access: yes, 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.

Comparing gender-specific suicide mortality rate trends in the United States and Lithuania, 1990–2019: putting one of the “deaths of despair” into perspective

open access: yesBMC Psychiatry, 2022
Introduction The increase in the suicide mortality rate among middle-aged adults in the United States (US) has been well documented. Aside from a few studies from the United Kingdom, it is unclear whether the suicide mortality rate trend in the US is ...
