Constraining the driving mechanism of galaxy-scale winds with emission line spectra (2023)
Presentation / Conference Contribution
Stern, J., Oñorbe, J., Richings, A. J., Johnson, S. D., & Faucher-Giguère, C.-A. (2023, March). Constraining the driving mechanism of galaxy-scale winds with emission line spectra. Presented at Black Hole Winds at All Scales : IAU symposium 378, Haifa, Israel

Using hydrodynamic simulations and photoionization calculations, we demonstrate that quasar emission line spectra contain information on the driving mechanism of galaxy-scale outflows. Outflows driven by a hot shocked bubble are expected to exhibit L... Read More about Constraining the driving mechanism of galaxy-scale winds with emission line spectra.

Observations of pulsar scintillation are among the few astrophysical probes of very small-scale ( au) phenomena in the interstellar medium (ISM). In particular, characterization of scintillation arcs, including their curvature and intensity distribut...

Annual variations of interstellar scintillation can be modelled to constrain parameters of the ionized interstellar medium. If a pulsar is in a binary system, then investigating the orbital parameters is possible through analysis of the orbital varia...

Monthly notices of the Royal Astronomical Society, 524(4), 5768-5780. https://doi.org/10.1093/mnras/stad1125

The large-scale structure of the Universe is comprised of galaxy filaments, tendrils, and voids. The majority of the Universe's volume is taken up by these voids, which exist as underdense, but not empty, regions. The galaxies found inside these void...

Traditional approaches to flood modelling mostly rely on hydrodynamic physical simulations. While these simulations can be accurate, they are computationally expensive and prohibitively so when thinking about real-time prediction based on dynamic env...

Presentation / Conference Contribution
Mboli, J. S., Thakker, D., & Mishra, J. (2023, April). Artificial Intelligence-Powered Decisions Support System for Circular Economy Business Models. Presented at International Conference on Enterprise Information Systems, ICEIS - Proceedings, Prague, Czech Republic

The circular economy (CE) is preferred to linear economy (LE) as it aims to keep resources in use for as long as possible, extracting maximum value before recovering and regenerating them. This reduces the need to extract new raw materials and reduce... Read More about Artificial Intelligence-Powered Decisions Support System for Circular Economy Business Models.
