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…

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…

Identification of 40 gravitationally magnified stars in a galaxy at redshift of 0.725

Yoshinobu Fudamoto, Fengwu Sun, Jose M. Diego +44

Strong gravitational magnifications enable to detect faint background sources, resolve their internal structures, and even identify individual stars in distant galaxies. Highly mag…

Conditions for detecting lensed Population III galaxies in blind surveys with the James Webb Space Telescope, the Roman Space Telescope and Euclid

Anton Vikaeus, Erik Zackrisson, Daniel Schaerer +5

Dark matter halos that reach the HI-cooling mass without prior star formation or external metal pollution represent potential sites for the formation of small - extremely faint - P…
