The detection and characterization of highly magnified stars with JWST: Prospects of finding Population III
Erik Zackrisson, Adam Hultquist, Aron Kordt +10
Gravitational lensing may render individual high-mass stars detectable out to cosmological distances, and several extremely magnified stars have in recent years been detected out t…

Spectroscopic characterisation of gravitationally lensed stars at high redshifts
Emma Lundqvist, Erik Zackrisson, Calum Hawcroft +2
Deep imaging of galaxy cluster fields have in recent years revealed tens of candidates for gravitationally lensed stars at redshifts 1-6, and future searches are expecte…

Explanations for the two-component spectral energy distributions of gravitationally lensed stars at high redshifts
Armin Nabizadeh, Erik Zackrisson, Emma Lundqvist +4
Observations of gravitationally lensed, high-mass stars at redshifts occasionally reveal spectral energy distributions that contain two components with different effecti…
