Predictions for astrometric microlensing in Gaia

Zofia Kaczmarek, David Sweeney, Łukasz Wyrzykowski +1

ESA's astrometric space mission Gaia is uniquely positioned for microlensing studies thanks to its all-sky coverage and simultaneous astrometric and photometric observations. In Ga…

Mitigating effects of telescope jitter through differentiable forward-modeling

Max Charles, Louis Desdoigts, Benjamin Pope +3

Instabilities in telescope pointing, commonly referred to as jitter, introduce image degradation that can compromise the accuracy of critical scientific observables. This work pres…

The TOLIMAN mission: A low-cost space telescope for high precision narrow-angle astrometry

Peter Tuthill, Christopher Betters, Max Charles +29

The TOLIMAN project is engaged with the construction, launch and operation of a low-cost space telescope of unorthodox optical design. Its primary science goal targets an exhaustiv…

Semi-Supervised Learning for Lensed Quasar Detection

David Sweeney, Alberto Krone-Martins, Daniel Stern +7

Lensed quasars are key to many areas of study in astronomy, offering a unique probe into the intermediate and far universe. However, finding lensed quasars has proved difficult des…

Observing the Galactic Underworld: Predicting photometry and astrometry from compact remnant microlensing events

David Sweeney, Peter Tuthill, Alberto Krone-Martins +3

Isolated black holes (BHs) and neutron stars (NSs) are largely undetectable across the electromagnetic spectrum. For this reason, our only real prospect of observing these isolated…

Nonlinear wavefront reconstruction from a pyramid sensor using neural networks

Alison P. Wong, Barnaby R. M. Norris, Vincent Deo +7

The pyramid wavefront sensor (PyWFS) has become increasingly popular to use in adaptive optics (AO) systems due to its high sensitivity. The main drawback of the PyWFS is that it i…

The Galactic Underworld: The spatial distribution of compact remnants

David Sweeney, Peter Tuthill, Sanjib Sharma +1

We chart the expected Galactic distribution of neutron stars and black holes. These compact remnants of dead stars -- the Galactic underworld -- are found to exhibit a fundamentall…

Learning the Lantern: Neural network applications to broadband photonic lantern modelling

David Sweeney, Barnaby R. M. Norris, Peter Tuthill +4

Photonic lanterns allow the decomposition of highly multimodal light into a simplified modal basis such as single-moded and/or few-moded. They are increasingly finding uses in astr…

Achromatic photonic tricouplers for application in nulling interferometry

Marc-Antoine Martinod, Peter Tuthill, Simon Gross +3

Integrated-optic components are being increasingly used in astrophysics, mainly where accuracy and precision are paramount. One such emerging technology is nulling interferometry t…
