A galaxy's angular momentum is known to be correlated with its morphology: at a given mass, spiral galaxies have higher angular momenta than elliptical galaxies. A galaxy's angular momentum is also largely set by its formation history: in particular, how much gas and the kinematic state of the gas that both accretes onto it and is expelled in galactic outflows from AGN and supernovae. All gas inflowing to and outflowing from the galaxy interacts with gas in the region surrounding the galaxy called the circumgalactic medium (CGM), which means at a fundamental level, the CGM controls the angular momentum of the galaxy. Therefore, to really understand the origins of galactic angular momentum, it is necessary to understand the angular momentum of the CGM itself. In this dissertation, I present a series of projects aimed at studying angular momentum in the CGM using the Illustris and IllustrisTNG cosmological hydrodynamical simulations suites. In an appendix, I also present a project on searching a survey of neutral hydrogen for previously undetected ultra-faint dwarf galaxies in and around the Milky Way's CGM. First, to understand how present-day galaxies acquire their observed angular momentum, I analyze the evolution of the angular momentum of Lagrangian gas mass elements as they accrete onto dark matter halos, condense into Milky Way-scale galaxies, and join the z=0 stellar phase of those galaxies. I find that physical feedback from the galaxy is essential in order to produce reasonable values of galactic angular momentum, and that most of the effects of this feedback occur in the CGM, necessitating studying the angular momentum of the CGM itself. Following on from this result, I then characterize the angular momentum distribution and structure within the CGM of simulated galaxies over a much larger range of halo masses and redshifts, with the goal of determining if there are common angular momentum properties in CGM populations. I indeed find that the angular momentum of the CGM is larger and better aligned around disk galaxies that themselves have high angular momentum. I also identify rotating structures of cold gas that are generally present around galactic disks. This clear connection of the CGM to the galaxy motivated a detailed comparison to observations of cold CGM gas. I perform this comparison in the following chapter where I use the highest-resolution simulation from the IllustrisTNG suite of cosmological magneto-hydrodynamical simulations to generate synthetic observations of cold CGM gas around star-forming galaxies in order to study kinematics and compare them to line-of-sight observations of cold gas near comparable galaxies. With this direct comparison to observations of the CGM, I show that IllustrisTNG produces rotating CGM gas consistent with observations to a high degree. In the penultimate chapter I present unpublished work where I begin to examine angular momentum evolution in the CGM on much finer timescales than can be resolved with the cosmological simulations I have used thus far. Preliminary results suggest that gas can experience large changes in angular momentum very quickly, and that these changes may be connected to corresponding changes in the temperature of the gas. Finally, I conclude by summarizing my main results and briefly discussing what questions still remain unanswered and my plans and strategies for pursuing these questions in my future work.

The Standard Model of elementary particles (SM) predicts the existence of a neutral scalar Higgs boson. However, there are also extensions of the SM (such as the MSSM) in which a number of Higgs bosons is predicted. Especially the additional presence of pseudoscalar and charged Higgs bosons represents one of the crucial differences between the SM and its exten- sions. This work develops a method for determination of the spin and parity of the Higgs boson in several H → ττ decays, namely: H→ τ+ τ− → (h+ ντ )(h− ¯ντ ), H→ τ+ τ− → ( + ντ ¯ν )(π− ¯ντ ) and H→ τ+ τ− → ( + ντ ¯ν )( − ¯ντ ν ), where h denotes π or ρ meson. The method is based on the angular and energy correlations of charged final products from the decays mentioned above. Additionally, the work studies the possibility of signal (Higgs boson decay) and background (Z → ττ decay) discrimination, when one considers a decaying boson with spin 1. All calcula- tions are done in the leading order of perturbation theory. 1

We present a first measurement of time-dependent CP-violation in B0 → D∗∓ ρ± , where D∗∓ → D0 π. The analysis was performed using the final Belle dataset containing 772 × 106 B ¯B pairs collected at the KEKB e+ e− collider. Three D0 decay modes are analyzed, K∓ π± , K∓ π± π0 , and K∓ π± π∓ π± . Since the studied decay is a scalar → vector vector decay, three helicity configurations are present. Exploiting the helicity configura- tions via angular analysis, the time-dependent CP-violation parameters encoding 2ϕ1 +ϕ3 are obtained from the fit. 1

JavaScript har under de senaste sju åren varit det mest populära programmeringsspråket. JavaScript har ständigt utvecklats, så har även webben. Detta har lett till att det är möjligt att utveckla webbsidor som liknar riktiga mobilapplikationer, även kallat progressiva webbapplikationer. I denna studie var syftet att identifiera, undersöka och jämföra olika JavaScript-ramverk som kan användas för att skapa progressiva webbapplikationer. För att uppnå detta har granskningen skett i tre steg. Det första steget var att identifiera ramverk som tydligt identifierade sig själva som ramverk och främst fokuserade på klientsidan. Under första steget insamlades information om elva ramverk som uppfyllde kraven. Nästa granskning i steg ett var att identifiera de ramverk som återgav information på sin officiella webbsida om hur en progressiv webbapplikation implementeras. Efter denna granskning återstod endast två ramverk, Angular och Vue.js. I steg två utvecklades en identisk webbapplikation i vardera ramverk. I det tredje och sista steget jämfördes ramverken baserat på 15 riktlinjer vid val av ramverk för att slutligen avgöra vilket ramverk som var att föredra vid utveckling av en progressiv webbapplikation. Resultatet visade att Vue.js var det ramverk som rekommenderas vid implementering av en progressiv webbapplikation. Detta baserades på att ramverket krävde färre kodrader samt att ramverket funnits längre på marknaden. Ytterligare en anledning var att ramverket är mest populärt bland utvecklare på GitHub.

Introduction: Blazor is a new framework and current research show that there is a lack of performance comparisons. Therefore, a need to compare and evaluate this new Blazor framework is ought to be requested to show if it can compete with one of the best and most used frameworks, Angular. It is also one of the few web developing frameworks that has moved away from using JavaScript and therefore a comparison with a framework that uses JavaScript will be very interesting. Aim: The aim of this study is to make a performance comparison between two web applications using the Angular and Blazor frameworks. I will evaluate the performance and present the results to see if Blazor can compete with Angular as a modern web development framework. More specifically, the study aims to answer the following research question: Based on a performance evaluation would it be favorable for a developer or company to consider usingthe Blazor framework over the Angular framework when developing web applications? Method: I started by doing a literature review of the field I wanted to research. I used du.se library search engine, which had access to the DiVa portal, Google scholar, Summon and Libris etc. The literature was found using the keywords “Blazor”, “Angular”, “Web application”, “Framework”, “Comparison” and “Evaluation”. Thereafter, two web applications were developed for the purpose of performance evaluation of the two frameworks. An evaluation tool was used to create the report based on the measurement criterions: “First Contentful Paint”, “Time to Interactive”, “Speed Index”, “Total Blocking Time”, “Largest Contentful Paint” and “Cumulative Layout Shift”. When evaluating I summed up which framework that was more favorable in each category and displayed it in tables and graphs. Results: I found that the Angular framework was more favourable in 4 out of the 6 criterions. Even though Angular performed better overall it showed some very unstable performance results during the twenty tests. Blazor displayed a stable performance throughout all twenty tests in all categories and was very fast and responsive once the initial load of the client was done. Conclusions: Based on the results Angular was the more favourable framework during my tests, due to overall performance. But the Angular framework showed too many inconsistencies during the tests to call it superior, meanwhile Blazor performed very stable results. This indicates that the Blazor framework can possibly compete with the Angular framework as a modern web development framework. Thus, my conclusion is that it would be favourable for developers and companies to consider using the Blazor framework for new projects, especially if they have previous experience with the C# language or are new to web developement.

The objective of this work is to develop a near-infrared laser device capable of emitting orbital angular momentum (OAM) light. The prototyped device must be suitable for compact, energy-saving optical communication applications. Integrated OAM lasers will revolutionize high-capacity data transmission over any telecommuni- cation network environment, as OAM light can be guided and transmitted through kilometers of optical fibers and propagated in free space and underwater. Several methods for generating OAM light employing various complex monolithic and hybrid integration methods have been demonstrated. In this work, microscale integrated spiral phase plates (SPPs) are chosen to convert the laser beam output into an OAM mode. The concept and design fundamentals of SPPs are discussed, followed by the SPP fabrication process and their implementation in a high-speed communication setup and then integration with a semiconductor laser. SPPs are fabricated by a novel direct laser writing that provides the possibility to rapidly prototype 3D photonic structures via a two-photon polymerization pro- cess. After fabrication, SPPs are used in a fine-tuned free-space optical experimental setup that requires high-precision intercomponent alignment to test the high-speed OAM communication system and analyze the quality of OAM modes, resulting in high-purity OAM signals at data rates up to 1.8 Gbit/s – limited by the avalanche photodetector (APD) frequency response. The fabricated 20-μm-diameter SPPs were the smallest reported in the literature to date for optical characterization. A proof-of-concept monolithic light-emitting array, as a highly integrated OAM laser source, is further proposed for telecommunications and other applications. SPP-integrated 940-nm vertical-cavity surface-emitting laser (VCSEL) array chips that are relatively low-cost, have a small footprint, and are manufacturable in high volumes are developed. SPPs with topological charge modulus values from 1 to 3 are fabricated on the VCSEL arrays, demonstrating OAM modal purities up to ∼65%. The experimentally evaluated data rates in the OAM setup showed consistently sta- ble links up to 2.0 Gbit/s with a bit error ratio of ∼ 1.6 × 10−8 (APD-limited). The challenges of SPP-laser integration are summarized, with the conclusion that the widespread adoption of OAM is limited by the availability of practical integrated solutions for OAM generation and detection.
