Metal factories in the early universe (2024)
Journal Article

We have estimated the mass of metals in the molecular gas in 13 dusty star-forming galaxies at z ∼ 4 in which the gas, based on previous observations, lies in a cold rotating disk. We estimated the metal masses using either the submillimetre line or... Read More about Metal factories in the early universe.

Reconsidering the dynamical states of galaxy clusters using PCA and UMAP (2024)
Journal Article

Numerous metrics exist to quantify the dynamical state of galaxy clusters, both observationally and within simulations. Many of these correlate strongly with one another, but it is not clear whether all of these measures probe the same intrinsic prop...

Shock wave generation and propagation in dissipative and nonlocal nonlinear Rydberg media (2024)
Journal Article

We investigate the generation of optical shock waves in strongly interacting Rydberg atomic gases with a spatially homogeneous dissipative potential. The Rydberg atom interaction induces an optical nonlocal nonlinearity. We focus on local nonlinear (...

Smoothed asymptotics: from number theory to QFT (2024)
Journal Article

Inspired by the method of smoothed asymptotics developed by Terence Tao, we introduce a new ultraviolet regularisation scheme for loop integrals in quantum field theory which we call η regularisation. This reveals a connection between the elimination... Read More about Smoothed asymptotics: from number theory to QFT.

Local versus global environment: The suppression of star formation in the vicinity of galaxy clusters (2024)
Journal Article

In order to examine where, how and why the quenching of star formation begins in the outskirts of galaxy clusters, we investigate the de-projected radial distribution of a large sample of quenched and star-forming galaxies (SFGs) out to 30R500 around...

Tracking the neurodevelopmental trajectory of beta band oscillations with optically pumped magnetometer-based magnetoencephalography (2024)
Journal Article

Neural oscillations mediate the coordination of activity within and between brain networks, supporting cognition and behaviour. How these processes develop throughout childhood is not only an important neuroscientific question but could also shed lig...

Tracking head movement inside an MR scanner using electromagnetic coils (2024)
Journal Article

Prospective motion corrections in brain imaging for MRI are fairly challenging. Monitoring involuntary head movement inside MR scanner is crucial for prospective motion correction. This initial study delves into utilizing simulations to track the hea... Read More about Tracking head movement inside an MR scanner using electromagnetic coils.

Tripartite quantum Rabi model with trapped Rydberg ions (2024)
Journal Article

We investigate a tripartite quantum Rabi model (TQRM) wherein a bosonic mode concurrently couples to two spin-1/2 particles through a spin-spin interaction, resulting in a spin-spin-boson coupling - a departure from conventional quantum Rabi models f...

Spectral Signatures of Vibronic Coupling in Trapped Cold Ionic Rydberg Systems (2024)
Journal Article

Atoms and ions confined with electric and optical fields form the basis of many current quantum simulation and computing platforms. When excited to high-lying Rydberg states, long-ranged dipole interactions emerge which strongly couple the electronic...

Real-imaginary spectrum decomposition of the transparency spectra in microwave dressed Rydberg systems (2024)
Journal Article

To distinguish the contributions of electromagnetically induced transparency (EIT) and Autler-Townes splitting (ATS) in their applications in precision laser spectroscopy, we propose a real-imaginary spectrum decomposition method to investigate the t...

Increasing AGN sample completeness using long-term near-infrared variability (2024)
Journal Article

In this work, we use 8 years of deep near-infrared imaging to select and study a new set of 601 active galaxies identified through long-term near-infrared (NIR) variability in the UKIDSS Ultra Deep Survey (UDS). These objects are compared to 710 X-ra... Read More about Increasing AGN sample completeness using long-term near-infrared variability.

Simultaneous whole-head electrophysiological recordings using EEG and OPM-MEG (2024)
Journal Article

Electroencephalography (EEG) and magnetoencephalography (MEG) non-invasively measure human brain electrophysiology. They differ in nature; MEG offers better performance whilst EEG (a wearable platform) is more practical. They are also complementary,...
