This study investigates the main large-scale drivers of precipitation variability. Using monthly reanalysis data spanning 46 years (1979–2025), it examines the causal pathways driving precipitation over Europe and the North Atlantic during the winter season. To this end, causal inference methods are applied, with the aim of revealing temporal and spatial structures that differ from those...

The physical properties of a cell, such as stiffness and elasticity, are primarily governed by its cytoskeleton which is mainly made of three filament types. One these is intermediate filaments, which have recently gained interest because of their remarkable mechanical properties, exceptional stiffness at large deformations and elasticity on the other hand. They form a dynamic network that can...

A new deep ice-core record from the East Antarctic Plateau reaching at least 1.2 million years is now available through the Beyond EPICA Oldest Ice Core project (BEOIC). This record spans the Mid-Pleistocene Transition (MPT), when glacial-cycle pacing shifted from ~40,000 years to ~100,000 years, and therefore offers key constraints when combined water-isotope and greenhouse-gas measurements...

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...

Mitochondria serve as the epicentre of energy production of the eukaryotic cell, generating most of the adenosine triphosphate (ATP) required for cellular processes. This energy conversion is carried out by the respiratory chain complexes, including the electron transport chain (ETC) and F_0 F_1-ATP synthase, which are located within specialized invagination of the inner mitochondrial membrane...

In physics, oscillations, e.g. of springs, are adiabatic processes. They conserve both energy and entropy. This can be monitored by observing the oscillating temperature. Oscillations also exist in chemistry. Such oscillations are described in the literature by reaction-diffusion networks of coupled rate equations that only contain chemical concentrations as variables. Therefore, these...

In the context of phenomenological modified gravity, Starobinsky inflation is considered one of the most successful inflationary models. However, from a fundamental physics perspective, it faces a significant naturalness challenge. Compatibility with cosmological observations requires a remarkably strong hierarchy: the $R^2$ term must be extremely large, while higher-order corrections must be...

Where do ultra-high-energy cosmic rays—the most energetic particles known in the Universe—come from? For decades, the question has remained unanswered. Ultra-high-energy neutrinos, born from cosmic-ray interaction and with energies more than 10,000 times higher than particles made in human-made accelerators—are key to solving this mystery. Yet, so far, we have detected but a single...

Traditionally, antiferromagnetism is a type of commensurate magnetic ordering, exhibiting Kramer's degenerate bands. Recently, it was discovered that symmetry could enforce a spin splitting of the bands. Such magnetic orders can be categorised into altermagnets with even parity spin splitting and odd-parity magnets, sometimes called antialtermagnets. In my thesis, I calculate the local...

Black hole spectroscopy is a vibrant field of research with significant potential to uncover new physics. Despite its importance and development over the last years, very little is known about how the different characteristic modes of black holes, called quasinormal modes, are excited, and how this relates to the physics of light rings. In this project we study the excitation of the...
