X-ray telescopes such as @NASANuSTAR record the time an X-ray photon hits the detector, its position on the detector, and its energy. The…

In this paper we show how the first Ultraluminous pulsar, M82 X-2, behaves in a peculiar way that makes us think that it is close to the so…

This paper describes the design and implementation of stingray, a library in Python built to perform time series analysis and related tasks…

In this series of papers we describe a technique called Fourier Amplitude Difference (FAD) correction, that fully corrects the dead time…

I wrote a review on the recent advances in our understanding of Ultraluminous X-ray pulsars. You can find it (published on Astronomische…

Dead time can affect NuSTAR timing analysis. Let us learn how to approach it. The paper was published in The Astrophysical Journal and…

Pulsation detected from an ultraluminous X-ray source unequivocally identify it as a neutron star. The paper was published on Nature and…

The spectra of ultraluminous X-ray sources are curved at high X-ray energies, as one would expect from super-critical black holes. The paper…
