Following up the Kepler field with PLATO: Transit Timing Performance

Morgan A. Mitchell, James McCormac, Don Pollacco +11

The European Space Agency is set to launch PLATO, the third medium-class mission of its Cosmic Vision programme, in early 2027. Using the transit method, PLATO is expected to detec…

The Future of Evolved Planetary Systems

Roberto Raddi, Anna F. Pala, Alberto Rebassa-Mansergas +19

Understanding the formation, evolution, and chemical diversity of exoplanets are now central areas of astrophysics research. White dwarfs provide a uniquely sensitive laboratory fo…

CarboFormer: A Lightweight Semantic Segmentation Architecture for Efficient Carbon Dioxide Detection Using Optical Gas Imaging

Taminul Islam, Toqi Tahamid Sarker, Mohamed G Embaby +2

Carbon dioxide (CO) emissions are critical indicators of both environmental impact and various industrial processes, including livestock management. We introduce CarboFormer, a…

Classification of LEO Satellites Using Occultations of Background Stars

Benjamin F. Cooke, Don Pollacco, James A. Blake +4

We present the result of a proof-of-concept simulation designed to classify LEO satellites based on their occultations of background stars. We generate satellite shapes drawn from…

A comprehensive survey of the GEO-belt using simultaneous four-colour observations with STING

Robert J. S. Airey, Paul Chote, James A. Blake +7

Colour light curves of resident space objects (RSOs) encapsulate distinctive features that can offer insights into an object's structure and design, making them an invaluable tool…

Predicting RSO Populations Using a Neighbouring Orbits Technique

Benjamin F. Cooke, James A. Blake, Paul Chote +2

The determination of the full population of Resident Space Objects (RSOs) in Low Earth Orbit (LEO) is a key issue in the field of space situational awareness that will only increas…

Simulated recovery of LEO objects using sCMOS blind stacking

Benjamin F. Cooke, Paul Chote, Don Pollacco +5

We present the methodology and results of a simulation to determine the recoverability of LEO objects using a blind stacking technique. The method utilises sCMOS and GPU technology…

The alternating simultaneous Halpern-Lions-Wittmann-Bauschke algorithm for finding the best approximation pair for two disjoint intersections of convex sets

Yair Censor, Rafiq Mansour, Daniel Reem

Given two nonempty and disjoint intersections of closed and convex subsets, we look for a best approximation pair relative to them, i.e., a pair of points, one in each intersection…

Search for Transient, Monochromatic Light from the Galactic Plane

Geoffrey W. Marcy, Nathaniel K. Tellis

The Galactic Plane was searched for transient, monochromatic light at optical and near-IR wavelengths to detect pulses shorter than 1 sec. An objective-prism Schmidt telescope and…

A Search for Monochromatic Light Toward the Galactic Centre

Geoffrey W. Marcy, Nathaniel K. Tellis, Edward H. Wishnow

A region 140 square degrees toward the Galactic Centre was searched for monochromatic optical light, both pulses shorter than 1 sec and continuous emission. A novel instrument was…

Laser Communication with Proxima and Alpha Centauri using the Solar Gravitational Lens

Geoffrey W. Marcy, Nathaniel K. Tellis, Edward H. Wishnow

A search was conducted for laser signals, both sub-second pulses and continuous emission, from the regions of the sky opposite Proxima and Alpha Centauri. These regions are located…

Exploring nine simultaneously occurring transients on April 12th 1950

Beatriz Villarroel, Geoffrey W. Marcy, Stefan Geier +6

Nine point sources appeared within half an hour on a region within 10 arcmin of a red-sensitive photographic plate taken in April 1950 as part of the historic Palomar Sky Su…

A Search for Optical Laser Emission from Proxima Centauri

Geoffrey W. Marcy

A search for laser light from Proxima Centauri was performed, including 107 high-resolution, optical spectra obtained between 2004 and 2019. Among them, 57 spectra contain multiple…
