An H i absorption distance to the black hole candidate X-ray binary MAXI J1535–571 [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society Letters, 2019
With the Australian Square Kilometre Array Pathfinder (ASKAP) we monitored the black hole candidate X-ray binary MAXI J1535–571 over seven epochs from 2017 September 21 to October 2. Using ASKAP observations, we studied the H i absorption spectrum from

A Wildly Flickering Jet in the Black Hole X-Ray Binary MAXI J1535–571 [PDF]

open access: yesAstrophysical Journal, 2018
We report on the results of optical, near-infrared (NIR), and mid-infrared observations of the black hole X-ray binary candidate (BHB) MAXI J1535–571 during its 2017/2018 outburst. During the first part of the outburst (MJD 58004–58012), the source shows

FCHO1560-571 peptide, a PKB kinase motif, inhibits tumor progression.

open access: yesBiochemical and Biophysical Research Communications - BBRC, 2020
BACKGROUND Cell division is regulated by protein kinase B (PKB)-mediated FCH domain only 1 (FCHO1) phosphorylation. METHODS FCHO1560-571, a synthetic water-soluble peptide, was generated from the PKB substrate motif 560PPRRLRSRKVSC571 found in the ...

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.

Complement factor H levels are decreased and correlated with serum C-reactive protein in late-onset Alzheimer's disease [PDF]

open access: yesArquivos de Neuro-Psiquiatria, 2020
Alzheimer’s disease (AD) is the most common cause of dementia. Despite numerous studies on the subject, the pathologies for AD are still unclear and there is still no ideal biomarker for diagnosis.

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 ...

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 ...
