This project investigates current challenges to the cold dark matter (CDM) paradigm by studying the effects of dark matter on cosmological and galactic scales. In particular, it focuses on small scale observations, such as the centres of galaxies, where the data might suggest an alternative dark matter model such as self-interacting dark matter (SIDM).
Using IllustrisTNG as a baseline and...

This project investigates the impact different theoretical dark matter models can have on galactic structure on small-scale. The two models being considered is the Cold Dark Matter (CDM) and Self-Interacting Dark Matter (SIDM), since SIDM is a current proposal to a solution of the small-cale problem arising from the most succesful dark matter model, CDM. To investigate detailed differences...

High- and very-high-energy gamma rays from distant extragalactic sources are severely attenuated due to interactions with the extragalactic background light (EBL). This effect could be partially alleviated by introducing Axion-like particles (ALPs), a beyond-Standard Model dark matter candidate that allows for photon-to-ALP oscillations in astrophysical magnetic fields. These oscillations...

Cryogenic Single-Photon Detectors, such as Transition-Edge-Sensors (TES) and Superconducting Nanowire Single-Photon Detectors (SNSPD), have achieved high detection efficiency larger than 85\% for optical and near-infrared wavelengths. Fiber-Coupled Blackbody photons has been identified as the dominant source of background signals for both detector systems. In order the achieve ultra-low...

Nearby dwarf galaxies are strongly dark matter-dominated, making them ideal laboratories for testing empirical relations between dynamical and baryonic properties. A key example is the Radial Acceleration Relation (RAR), describing a tight correlation between baryonic and observed acceleration across a wide mass range. Whether this relation holds in the lowest-mass, dark matter–dominated...

The distribution of dwarf satellite galaxies around massive hosts serves as a useful probe of dark matter at small scales, especially since the effect of baryonic matter within the galaxies themselves on their spatial distribution is minimal. Here, I examine our neighbouring galaxy Andromeda, which hosts a strikingly asymmetrical distribution of satellites aligned towards the Milky Way. I...

Superconducting nanowire single-photon detectors (SNSPDs) are a leading technology for single-photon detection in quantum science and its applications, thanks to their high detection efficiency, low noise, and unmatched timing resolution. These properties make SNSPDs attractive candidates for novel rare-event searches, such as those for axions and axion-like particles. However, the presence of...
