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…
Project Hephaistos - II. Dyson sphere candidates from Gaia DR3, 2MASS, and WISE
Matías Suazo, Erik Zackrisson, Priyatam K. Mahto +5
The search for extraterrestrial intelligence is currently being pursued using multiple techniques and in different wavelength bands. Dyson spheres, megastructures that could be con…
EPOCHS III: Unbiased UV continuum slopes at 6.5<z<13 from combined PEARLS GTO and public JWST NIRCam imaging
Duncan Austin, Christopher J. Conselice, Nathan J. Adams +34
We present an analysis of rest-frame UV continuum slopes, , using a sample of 1011 galaxies at from the EPOCHS photometric sample collated from the GTO PEARLS and pub…
JWST MIRI detections of H and [O III] and direct metallicity measurement of the lensed galaxy MACS0647JD
Tiger Yu-Yang Hsiao, Javier Álvarez-Márquez, Dan Coe +30
JWST spectroscopy has revolutionized our understanding of galaxies in the early universe. Covering wavelengths up to , NIRSpec can detect rest-frame optical emission…
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…
