Links between optical and X-ray light in Scorpius X-1 (2023)
Journal Article
Igl, A. B., Hynes, R. I., Britt, C. T., O’Brien, K. S., & Mikles, V. J. (2023). Links between optical and X-ray light in Scorpius X-1. Monthly Notices of the Royal Astronomical Society, 526(1), 645–660. https://doi.org/10.1093/mnras/stad2721

We observed the low-mass X-ray binary Sco X-1 for 12 nights simultaneously using the Rossi X-Ray Timing Explorer and the Otto Struve Telescope at McDonald Observatory at 1-s time-resolution. This is among the most comprehensive simultaneous X-Ray/opt... Read More about Links between optical and X-ray light in Scorpius X-1.

Sub-second infrared variability from the archetypal accreting neutron star 4U 1728−34 (2023)
Journal Article
Vincentelli, F. M., Casella, P., Borghese, A., Cavecchi, Y., Mastroserio, G., Stella, L., …Uttley, P. (2023). Sub-second infrared variability from the archetypal accreting neutron star 4U 1728−34. Monthly Notices of the Royal Astronomical Society, 525(2), 2509-2518. https://doi.org/10.1093/mnras/stad2414

We report on the first simultaneous high-time resolution X-ray and infrared (IR) observations of a neutron star low mass X-ray binary in its hard state. We performed ≈ 2 h of simultaneous observations of 4U 1728−34 using HAWK-I@VLT, XMM– Newton, and...

CUBES: application of image slicers to reformat the field for two spectral resolving powers (2022)
Presentation / Conference Contribution

The Cassegrain U-Band Efficient Spectrograph (CUBES) is a high-efficiency spectrograph designed for observations from 305 to 400nm. It will be integrated at a Cassegrain focus of the Very Large Telescope (VLT). The image slicer technology is applied...

Fast infrared variability from the black hole candidate MAXI J1535−571 and tight constraints on the modelling (2021)
Journal Article

We present the results regarding the analysis of the fast X-ray/infrared (IR) variability of the black hole transient MAXI J1535−571. The data studied in this work consist of two strictly simultaneous observations performed with XMM–Newton (X-rays: 0...

First Principle Simulator of a Stochastically Varying Image Plane for Photon-counting High Contrast Applications (2020)
Journal Article

Optical and near-infrared Microwave Kinetic Inductance Detectors, or MKIDs are low-temperature detectors with inherent spectral resolution that are able to instantly register individual photons with potentially no false counts or readout noise. These... Read More about First Principle Simulator of a Stochastically Varying Image Plane for Photon-counting High Contrast Applications.

System mass constraints for the accreting millisecond pulsar XTE J1814-338 using Bowen fluorescence (2017)
Journal Article

We present phase-resolved spectroscopy of the millisecond X-ray pulsar XTE J1814-338 obtained during its 2003 outburst. The spectra are dominated by high-excitation emission lines of He II λ4686, Hβ, and the Bowen blend C III/N III 4630–50 Å. We expl...

Simulated stellar kinematics studies of high-redshift galaxies with the HARMONI Integral Field Spectrograph (2016)
Journal Article

We present a study into the capabilities of integrated and spatially resolved integral field spectroscopy of galaxies at z = 2–4 with the future HARMONI spectrograph for the European Extremely Large Telescope (E-ELT) using the simulation pipeline, HS...
