We present the most comprehensive analysis to date of the Upper Centaurus Lupus eclipsing binary MML 53 (with P-EB = 2.097892 d), and for the first time, confirm the bound-nature of the third star (in a P-3 similar to 9 yr orbit) by constraining its...

A molecular mechanism for transthyretin amyloidogenesis. (2019)
Journal Article
(2019). A molecular mechanism for transthyretin amyloidogenesis. Nature communications, https://doi.org/10.1038/s41467-019-08609-z

Human transthyretin (TTR) is implicated in several fatal forms of amyloidosis. Many mutations of TTR have been identified; most of these are pathogenic, but some offer protective effects. The molecular basis underlying the vastly different fibrillati... Read More about A molecular mechanism for transthyretin amyloidogenesis..

A deep X-ray view of the bare AGN Ark 120 - VI. Geometry of the hot corona from spectroscopic and polarization signatures (2019)
Journal Article
(2019). A deep X-ray view of the bare AGN Ark 120 - VI. Geometry of the hot corona from spectroscopic and polarization signatures. Astronomy and Astrophysics, A12 -A12. https://doi.org/10.1051/0004-6361/201834454

Context. The spectral shape of the hard X-ray continuum of Active Galactic Nuclei (AGN) can be ascribed to inverse Compton scattering of optical/UV seed photons from the accretion disc by a hot corona of electrons. This physical process produces a po... Read More about A deep X-ray view of the bare AGN Ark 120 - VI. Geometry of the hot corona from spectroscopic and polarization signatures.

A deep X-ray view of the bare AGN Ark 120 - V. Spin determination from disc-Comptonisation efficiency method (2019)

Context The spin of supermassive black holes (SMBH) in active galactic nuclei (AGN) can be determined from spectral signature(s) of relativistic reflection such as the X-ray iron Ka line profile, but this can be rather uncertain when the line of sig...

This case reports details of a multi-phased, geophysical survey to assist in a cold case search. The Police Service received witness intelligence that had stated an adult male “Fred” had been lured to an isolated area, killed and then buried vertical...

Context Transport of angular momentum has been a challenging topic within the stellar evolution community, even more since the recent asteroseismic surveys. All published studies on rotation using asteroseismic observations show a discrepancy betwee...

Using a sample of 81 galactic, detached eclipsing binary stars we investigated the global zero-point shift of their parallaxes with the Gaia Data Release 2 (DR2) parallaxes. The stars in the sample lay in a distance range of 0.04–2 kpc from the Sun....

The kinematics of isolated brown dwarfs in the Galaxy, beyond the solar neighborhood, is virtually unknown. Microlensing has the potential to probe this hidden population, as it can measure both the mass and five of the six phase-space coordinates (a...
