Cluster lenses
Clusters of galaxies are the most recently assembled, massive, bound structures in the
Universe. As predicted by General Relativity, given their masses, clusters strongly deform …

Masses of galaxy clusters from gravitational lensing
H Hoekstra, M Bartelmann, H Dahle, H Israel… - Space Science …, 2013 - Springer
Despite consistent progress in numerical simulations, the observable properties of galaxy
clusters are difficult to predict ab initio. It is therefore important to compare both theoretical …

Spectroscopic confirmation of two luminous galaxies at a redshift of 14
The first observations of the James Webb Space Telescope (JWST) have revolutionized our
understanding of the Universe by identifying galaxies at redshift z≈ 13 (refs.,–). In addition …

A Comprehensive Study of Galaxies at z∼ 9–16 Found in the Early JWST Data: Ultraviolet Luminosity Functions and Cosmic Star Formation History at the Pre …
We conduct a comprehensive study on dropout galaxy candidates at z∼ 9–16 using the first
90 arcmin 2 James Webb Space Telescope (JWST) Near Infrared Camera images taken by …

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 …

Bound star clusters observed in a lensed galaxy 460 Myr after the Big Bang
Abstract The Cosmic Gems arc is among the brightest and highly magnified galaxies
observed at redshift z≈ 10.2 (ref.). However, it is an intrinsically ultraviolet faint galaxy, in 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 …

UNCOVERing the extended strong lensing structures of Abell 2744 with the deepest JWST imaging
We present a new parametric lens model for the massive galaxy cluster Abell 2744 based
on new ultra-deep JWST imaging taken in the framework of the UNCOVER program. These …

An extremely compact, low-mass galaxy on its way to quiescence at z= 5.2
We report the discovery of a low-mass z= 5.200±0.002 galaxy that is in the process of
ceasing its star formation. The galaxy, MACS0417-z5BBG, is multiply imaged with …
