To this end I investigate modified fuzzy spherical harmonics (i.e. rectangluar matrix valued fuzzy spherical harmonics) which simultaneously form a basis for rectangular matrices. I derive and calculate their normalisations. Along with this I derive the AdS propagator in 2+1 dimensions as this is needed to facilitate the calculation... -

By assuming that the astronomical cycles is detectable in the spectral signal of a stratigraphic sediment-core, the depth can be transformed into time. Using bayesian inversion and 'combing' through possible sedimentation rates, this timeline can be calculated along with uncertainties. AstroComb is aimed at geologists and feature many adjustable parameters, with an ultimate goal of searching...

In the search for life in the universe one of the most important tools are biosignatures. Biosignatures are molecules produced by biological processes. Such molecules are detectable in exoplanet atmospheres. On Earth, an example of biosignatures we would see in our atmosphere would be oxygen $(O_2)$, Methane $(CH_4)$ and lastly Dimethyl sulfide (DMS). DMS is a sulfur-containing gas produced by...

The ionizing spectral energy distribution (SED) of active galactic nuclei (AGN) is a fundamental, yet poorly constrained quantity that governs the photoionization of the Broad Line Region (BLR). X-ray observations of the changing-look AGN Mrk 590 by Lawther et al. (2025) have revealed a Comptonizing inner accretion flow, providing a new constraint on the SED. This thesis uses the Cloudy...

Quantum Dots (QDs) are nanoscale semiconductor structures that can emit single photons, making them attractive building blocks for quantum applications. When embedded in photonic disk resonators, their emission can be greatly enhanced through the Purcell effect. However, for QDs to be practically useful, their emission must be stable and tunable. These are two challenges this project aims to...

We report transport measurements of a two-dimensional semiconductor-superconductor hybrid Josephson-junction array with a double-layer electrostatic gate, enabling independent in situ voltage-tuned inter-island coupling and proximity-induced superconductivity. We use this voltage to drive and study superconductor-insulator (SIT) and superconductor-metal (SMT) transitions within the same...

52. Investigating the Dark Matter Distribution in Dwarf Galaxies using Extragalactic Stellar Streams27/03/2026, 16:05Poster
The current best cosmological model, the $\Lambda$ Cold Dark Matter model, successfully explains the large scale structures of the universe. However, this model fails to explain some small scale observations. One key example of this discrepancy between theory and observations is the core-cusp problem. Theoretically, we expect steep inner density profiles for dark matter halos, while...

The Great Oxidation Event (GOE) occurred 2.54 billion years ago and transformed the composition of the Early Archean Earth’s atmosphere from being less than 1ppm of O2 to approximately 2% (Catling, et al. 2017). We model the processes behind the GOE by incorporating the complete photochemical network detailed in Liu et al. 2019 with additional reactions describing the process of carbon burial...

on Earth. Traveling across the breadth of the observable Universe, they bring us unaltered information
from the most extreme astrophysical environments. However, because these particles are scarce and
interact with matter so rarely, detecting them requires specialized techniques. TAMBO... -

In my thesis, I investigate how a non-relativistic limit (c to infinity) can be applied to the framework of string theory. I focus in on the holographic principle, which relates gravity and quantum field theory. The goal of my thesis is to see how the holographic principle carries over to non-relativistic string theory.

Biological membranes, especially organelle membranes, are highly complex structures composed of diverse proteins and lipid types that are often distributed unevenly across the membrane surface. Understanding how these molecules are arranged laterally is essential for revealing how organelles interact with their environment. Although extensive experimental data exist on global membrane...

This thesis studies the temporal and spacial evolution of both gaseous and solid materials in protoplanetary disks. A model for evolving gas and dust as well as water in forms of both ice and vapor is set up. The icy dust grains experience hydrodynamic transport, collisional growth as well as sublimation/condensation of water when the disk temperature allows it. The gas is likewise...

38. Toward a kinetic model for the mechanical activation of the adhesion GPCR ADGRL3 in single cells27/03/2026, 16:05Poster
Adhesion G protein-coupled receptors (GPCRs) are proposed to play pivotal adhesive roles in neurons. We investigate mechanotransduction as a possible operating principle for adhesion GPCRs using an optical tweezer-based strategy at two different scales. At the cellular level, we use an optically trapped bead to apply forces directly to many ADGRL3 receptors (a prototypical adhesion GPCR) on...

In studying the evolution of galaxies, we observe a clear bimodality in both their morphology and colour space, discerning two distinct populations: blue, star-forming galaxies with a younger, UV-bright stellar population, and red, early-type galaxies, whose star formation has halted---so-called quiescent galaxies. Understanding the halting of star formation (termed quenching) is therefore...
