The past and ongoing gravitational wave detections have fostered a wide interest in understanding the formation of binary black holes (BBHs). Several formation scenarios have been proposed, including the evolution of isolated massive binaries. While most of the observed merging black holes are at cosmological distances, and thus likely at low metallicity, the Small Magellanic Cloud (SMC) provid...
Stars born in dense clusters often form binary systems, surrounded by circumbinary discs of gas and dust. Misalignments between these discs and the binary orbit are common during stellar evolution, driven by dissipation. My research, utilizing 3D hydrodynamical simulations, focuses on the evolution of highly misaligned circumbinary discs. I demonstrate that polar-aligned circumbinary discs are ...
In this study, we investigated the role of the inner halo's angular momentum distribution on bar formation and evolution processes. We performed a series of high-resolution N-body experiments with Milky Way-type disk galaxies. These models were initiated with similar disks but with varying inner halo angular momentum in the surrounding dark matter halo. The bar triggered earlier in the model wi...
Current and future weak lensing surveys contain significant information about our universe. However, their optimal cosmological analysis is challenging, with traditional analyses often resulting in information loss due to reliance on summary statistics like two-point functions. While deep learning methods offer promise in capturing the complex non-linear features of these cosmological fields, t...
Despite the vital importance of interstellar dust to many areas of astronomy, its composition and properties are highly uncertain. The dust extinction curve (the relation of extinction vs. wavelength) depends on both the grain-size distribution and the chemistry of the dust, and is therefore a probe of dust properties. The dust extinction curve is typically characterized by R(V) ≡ A(V)/E(B − ...
