Tidal disruption events (TDEs) provide a unique opportunity to probe the stellar populations around supermassive black holes (SMBHs). By combining light curve modeling with spectral line information and knowledge about in host galaxies, we are able constrain properties of disrupted star for three TDEs. The TDEs our sample have UV spectra, measurements N III C ratios enabled estimates nitrogen-to-carbon abundance these events. We show that measured nitrogen widths consistent originating from...
Galaxy mergers are crucial to understanding galaxy evolution, therefore we must determine their observational signatures select them from large IFU samples such as MUSE and SAMI. We employ 24 high-resolution idealised hydrodynamical merger simulations based on the "Feedback In Realistic Environment" (FIRE-2) model observability of various configurations stages using synthetic images velocity maps. Our cover a range orbital at fixed 1:2.5 stellar mass ratio for two gas rich spirals low...
We employ the Feedback In Realistic Environments (FIRE-2) physics model to study how properties of giant molecular clouds (GMCs) evolve during galaxy mergers. conduct a pixel-by-pixel analysis gas in both simulated control galaxies and major The GMC-pixels follow similar trend diagram velocity dispersion ($\sigma_v$) versus surface density ($\Sigma_{\mathrm{mol}}$) one observed local spiral Physics at High Angular resolution Nearby GalaxieS (PHANGS) survey. For mergers, we see significant...
Abstract We present a start-to-end simulation aimed at studying the long-term fate of high-mass X-ray binaries and whether Thorne–Żytkow object (TŻO) might ultimately be assembled. analyze results from 3D hydrodynamical that models eventual LMC X-4, compact binary system, after primary fills its Roche lobe engulfs neutron star companion. discuss outcome this engulfment within standard paradigm TŻO formation. The post-merger angular momentum content stellar core is key ingredient, as even...

We present a start-to-end simulation aimed at studying the long-term fate of high mass X-ray binaries and whether Thorne-\.Zytkow object (T\.ZO) might ultimately be produced. analyze results from 3D hydrodynamical that models eventual LMC X-4, compact binary system, after primary fills its Roche lobe engulfs neutron star companion. discuss outcome this engulfment within standard paradigm T\.ZO formation. The post-merger angular momentum content stellar core is key ingredient, as even small...
