Boson Stars in Dimensions: Stability, Oscillation Frequencies, and Dynamical Evolutions
Gareth Arturo Marks, Abdullah Al Zaif
We construct spherically symmetric boson star solutions in spacetime dimensions, considering the effects of both a quartic self-interaction term and a solitonic p…

Microlensing of lensed supernovae Zwicky & iPTF16geu: constraints on the lens galaxy mass slope and dark compact object fraction
Nikki Arendse, Edvard Mörtsell, Luke Weisenbach +9
To date, only two strongly lensed type Ia supernovae (SNIa) have been discovered with an isolated galaxy acting as the lens: iPTF16geu and SN Zwicky. The observed image fluxes for…
