High-impact climate events and tipping dynamics: assessing scientific understanding and future challenges

Gabriele C. Hegerl, Sabina Abba Omar, Alaa Al Khourdajie, Annett Bartsch et autres

This paper is motivated by growing concern about tipping dynamics and processes that can cause abrupt, self-amplifying, and irreversible changes across the Earth system and societies. It assesses current scientific understanding of the most severe climate outcomes, and proposes ways to address …

Deep Investigation of Neutral Gas Origins (DINGO): options for robust deep spectral line imaging in the SKA era

J. Rhee, Richard Dodson, Alexander W. Williamson, M. Meyer et autres

ABSTRACT The data storage requirements for deep spectral line observations with next-generation radio interferometers like the Australian Square Kilometre Array Pathfinder (ASKAP) and the SKA (Square Kilometre Array) are challenging. The default strategy is to reduce data after each daily observation and …

Resolving the blueshift in calculations of the EUV spectrum of multiply charged tin ions

Marten L. Reitsma, John Sheil, O. O. Versolato, E. Kahl et autres

We report relativistic calculations on the complex open shell Sn 12 + highly charged ion, a prototypical plasma ion relevant for extreme ultraviolet (EUV) nanolithography. Previous calculations of EUV emissivity in tin plasmas consistently generate a spectrum in which the region of …

Quantum Spectral Model: Data Reuploading with Input-Conditioned Frequency Support

Peiyong Wang, Udaya Parampalli, Casey R. Myers

A central design principle in modern machine learning and artificial intelligence is to align a model's inductive bias with the structure of its input data. For matrix-valued inputs, relevant matrix-level relationships can be characterised through spectral values and spectral subspaces; however, common …

A signal dedispersion algorithm for imaging-based transient searches

Cristian Di Pietrantonio, M. Sokołowski, Chris Harris, Danny C. Price et autres

Dedispersion is the computational process of correcting for the frequency-dependent time delay affecting a radio signal that propagates through the interstellar and intergalactic media. It is a crucial component of transient search pipelines that maximises the signal-to-noise ratio, especially when targeting highly …

Bridging the mass gap: diffuse radio emission in GAMA galaxy groups using EMU and DINGO survey data

S. M. Wagh, Tessa Vernstrom, L. J. M. Davies, L. Staveley‐Smith et autres

ABSTRACT Diffuse radio emission provides a powerful probe of non-thermal processes in the large-scale structure, yet its properties in galaxy groups remain poorly constrained. Using deep 943 MHz radio continuum data from the Evolutionary Map of the Universe and 1.37 GHz data …

Continuous-time quantum-walk-based ansätze on neutral-atom hardware

Edric Matwiejew, Jonathan Wurtz, Jing Chen, Pascal Jahan Elahi et autres

Continuous-time quantum walks offer provable speedups for certain computational problems, yet translating these advantages to near-term hardware remains challenging. We realize variational ans\"atze based on continuous-time quantum walks on an analog neutral-atom processor. For unentangled targets, we derive closed-form expressions for near-optimal …

The Southern-sky MWA Rapid Two-metre (SMART) pulsar survey--IV. Survey update and an atlas of 205 non-recycled southern pulsars

N. D. R. Bhat, C. P. Lee, SJ Mcsweeney, B. W. Meyers et autres

The SMART survey is an ambitious effort to conduct sensitive searches for pulsars and fast transients at 140-170 MHz. The novelty of voltage recording, long dwell times and the high-time and -frequency resolutions exchange a large survey speed for high computational cost. …

Onset of a Heavy Bombardment 1.4Ga ago Triggered by the Flora Asteroid Family and Its Implications for Earth–Moon Evolution

Anthony Lagain, Miroslav Brož, John Fairweather, Pierre Vernazza et autres

The collisional evolution of asteroids in the main belt between Mars and Jupiter has governed the flux of impactors delivered to the Earth–Moon system throughout much of Solar System history. The impact flux over the last ~3 billion years in the inner …

Fine-Tuning Large Language Models for Quantum Reasoning

Katherine Ip, Casey R. Myers, Udaya Parampalli, James Quach et autres

Large language models (LLMs) exhibit abilities beyond natural language modelling and text generation. Recent advances in their reasoning capabilities have spurred interest in applying LLMs to complex scientific tasks requiring deep domain expertise and sophisticated reasoning. Quantum computing, as a highly specialised …
