The James Webb Space Telescope provides unprecedented access to galaxies at a broad range of redshifts observed in a variety of filters, which correspond to different wavelengths of observation. Due to the extraordinary volume of accessible and distinct filters, we are able to see how physical information drastically changes based on the differences in galaxy emission captured at different...

This project aims to calibrate the Digital Optical Modules (DOMs) in the IceCube Neutrino Observatory using minimum ionizing muons. By analyzing simulated muon events in Monte Carlo data, we hope to determine the relative efficiency of which the DOMs have been simulated with. DOM efficiency is currently the third largest systematic uncertainty in IceCube, directly impacting event...

I am developing software to decrypt the complex UV-optical spectra of the gaseous region surrounding accreting supermassive black holes (SMBHs), such that we may advance our understanding of central SMBHs further. Emission from these regions is cryptic at best. Due to the highly energetic environment, physical gas components which contribute to the...

Oxygen trapped in ice cores provides information about past climate. This research has largely been concerned with single substituded oxygen, where one of the two oxygen atoms is substituted for an either O-17 or O-18. Much rarer and harder to measure is clumped oxygen, where both atoms are of rare isotopes. Clumped oxygen has the potential to provide information about the upper atmosphere in...

In 1915, Einstein formulated the general theory of relativity, which describes how massive objects bend and curve the fabric of spacetime. One of the main predictions of general relativity is the existence of black holes, which are dense regions of spacetime in which not even light can escape. Several detections and observations confirm the existence of black holes, including the trajectory of...

Due to the co-existence of different stable states (multi-stability), various climate components, such as the Amazon forest, the West African monsoon or the Atlantic meridional overturning circulation (AMOC), may undergo catastrophic regime shifts at varying levels of global warming. As a result, our uncertainty in future greenhouse gas emissions renders possible a variety of storylines with...

The study of the intergalactic medium (IGM) and its interaction with light from distant galaxies provides crucial insights into the evolution of the universe. In this project, I will apply a technique called "photometric intergalactic medium (IGM) tomography" to reconstruct a map of the large-scale structure of the IGM in the early Universe using a publicly available photometric catalogue and...

In quantum information science, encoding information in atomic states and reading it through light is essential for building quantum networks. Enhancing light-matter interaction is crucial for improving the efficiency of such processes, and optical cavities have emerged as a powerful tool in this regard. This project experimentally investigates the feasibility of measuring a collective state...

Active Galactic Nuclei (AGNs) are among the most luminous objects in the universe, powered by accretion onto supermassive black holes. The broad-line region (BLR), located within 5–30 light days of the black hole, produces strong emission lines that probe the ionization and kinematics of AGN gas. This project utilizes the Cloudy photoionization code to model BLR emission, incorporating new...

The Schwarzschild orbit-superposition method, developed for modeling galaxy dynamics, uses a combination of stellar orbits to represent the gravitational potential of a galaxy's center. This technique enables us to estimate the mass of the supermassive black hole (SMBH) residing in the galactic nucleus. Measuring the SMBH mass is crucial for understanding the growth and evolution of...

Extreme astrophysical environments may produce axion-like particles (ALPs), whose interactions could leave observable imprints on astronomical spectra. If they exist, ALPs may be a viable candidate for dark matter. In this project, we search for axion-induced spectral features in gamma-ray observations of active galactic nuclei (AGNs) that are aligned with galaxy clusters along the line of...

This master’s thesis investigates the role of supernova (SN) feedback in driving turbulence within the interstellar medium (ISM) of galaxies, a key factor in galaxy evolution. While SN feedback is considered to be one of the primary drivers of ISM turbulence, its efficiency across star-forming galaxies remains uncertain. This study focuses on dwarf galaxies in the local Universe, aiming to...

Current studies on star and planet formation suggest that many molecules form on the surfaces on icy grains in molecular clouds from where they are then accreted onto the emerging protoplanetary disk and in some cases sublimate due to the heating by the young star. However, it remains unclear what role the surrounding environment and/or its evolution plays in regulating the chemistry.
The...

As the Earth travels across the Milky Way, it passes through the galactic halo of dark matter particles. Occasionally a dark matter particle could interact with the contents of the earth, scattering it to a lower energy, which can lead to it becoming gravitationally trapped inside the Earth. If these dark matter particles are self-annihilating, or decay, one possible final state product will...

Precipitation in Denmark arises from different mechanisms across seasons. In winter, large-scale dynamics driven by the North Atlantic storm track dominate, while summer precipitation involves large-scale systems and local convective processes. Current climate models predict changes in these patterns, but since 2000, Denmark has experienced precipitation exceeding model predictions. Suggesting...

In this work we consider novel constructions for fault tolerant encoding and decoding interfaces in the context of channel codes that serve to protect quantum information being sent between a sender and receiver under the presence of general quantum noise. These encoding and decoding interfaces serve as the transitions between the physical quantum input output information of the system and the...

The Climate Crisis is one of the major challenges facing humanity today. To understand and predict how the Earth’s climate will respond to ongoing anthropogenic forcing, it is essential to first examine the dynamics of the climate system and its past variability. Ice sheets covering Greenland and Antarctica serve as crucial archives of past climate conditions, preserving proxies for...

With the increasing number of nuclear-resonant photons per pulse at x-ray free electron lasers (XFELs), achieving higher excitation levels experimentally becomes feasible. This development makes it particularly compelling to investigate light propagation and dynamics beyond the low-excitation regime (LER) and around population inversion. Thus, in my thesis, we examined the time response of...

Active matter encompasses a wide range of systems, from bird-flocks to bacterial colonies. Two main formalisms describe these systems based on individual particle symmetries: polar and nematic. Each formalism leads to unique behaviours, the most significant being the appearance of half and full integer topological defects for nematic and polar respectively. However, recent advances in the...

The first detection of gravitational waves (GWs) in 2015 opened the door to GW physics, which has allowed us to test Gravity with unprecedented precision.
When emitted by a source, usually a merging binary of compact objects such as black holes (BHs), gravitational waves propagate moslty unaltered through the cosmos. However, if they encounter objects in their path that are massive/compact...

The James Webb Space Telescope (JWST) has uncovered an unexpectedly high abundance of ultraviolet-bright galaxies early in the Universe, at redshifts beyond 10. Various explanations have been proposed, including bursty star formation, a top-heavy initial mass function (IMF) or a higher star formation efficiency. However, to date we lack physical models or simulations that has explored the...

With the advent of multimessenger astronomy, neutron stars are studied through multiple observational methods. These observations, combined with data from collider experiments such as those at the LHC at CERN, help constrain the Equation of State (EoS) of neutron matter. The symmetry energy parameter (Lsym) in the EoS is of great interest due to its connection with the neutron skin thickness...
