Revealing galaxy candidates out to z ∼ 16 with JWST observations of the lensing cluster SMACS0723
One of the main goals of the JWST is to study the first galaxies in the Universe. We present a
systematic photometric analysis of very distant galaxies in the first JWST deep field towards …

[HTML][HTML] Strong Lensing by Galaxy Clusters
Galaxy clusters as gravitational lenses play a unique role in astrophysics and cosmology:
they permit mapping the dark matter distribution on a range of scales; they reveal the …

A highly magnified star at redshift 6.2
Galaxy clusters magnify background objects through strong gravitational lensing. Typical
magnifications for lensed galaxies are factors of a few but can also be as high as tens or …

Constraining the physical properties of the first lensed z ∼ 9 − 16 galaxy candidates with JWST
The first deep-field observations of the JWST have immediately yielded a surprisingly large
number of very high redshift candidates, pushing the frontier of observability well beyond z≳ …
