Discovery of a Low-mass Strong-lens System in SMACS J0723.3−7327
The Astrophysical Journal LettersWe report the discovery of an intriguing, low-mass galaxy-scale strong-lens system in the SMACS J0723.3−7327 galaxy cluster. By modeling James Webb Space Telescope imaging and Very Large Telescope Multi-Unit Spectroscopic Explorer spectroscopic data, we ...

The Shape of the Chameleon Fifth-Force on the Mass Components of Galaxy Clusters
UniverseIn the context of chameleon gravity, we present a semi-analytical solution of the chameleon field profile in an accurately modelled galaxy cluster’s mass components, namely the stellar mass of the Brightest Cluster Galaxy (BCG), the baryonic mass in ...

Characterising galaxy clusters’ completeness function in Planck [PDF]
EPJ Web of ConferencesGalaxy cluster number counts are an important probe to constrain cosmological parameters. One of the main ingredients of the analysis is the selection function, and in particular the completeness, associated to the cluster sample one is considering ...

COMPARISON OF OPTICAL AND X-RAY MASS ESTIMATES OF THE CHANDRA GALAXY CLUSTERS AT Z < 0.1
Odessa Astronomical Publications, 2013 We used the optical data taken from SDSS DR7 galaxy and group catalog to determine the optical mass of 37 nearer Chandra galaxy clusters for comparison with the X-ray mass estimates.
