Development of an unbiased cosmic shear estimator measured on galaxy images
Enya Van den Abeele, Pierre Astier, Anna Niemiec
Since cosmic shear was first observed in 2000, it has become a key cosmological probe and promises to deliver exquisite dark energy constraints. However, shear is inferred from coh…
Mass & Light in Galaxy Clusters: The case of Abell 370
M. Limousin, A. Niemiec, B. Beauchesne +16
Parametric strong lensing studies of galaxy clusters often display "misleading features". This is the case in the galaxy cluster Abell 370. Using strong lensing techniques, it has…
The KALEIDOSCOPE survey : A new strong and weak gravitational lensing view of the massive galaxy cluster MACS J1423.8+2404
Nency R. Patel, Mathilde Jauzac, Anna Niemiec +6
We present a combined strong and weak gravitational-lensing analysis of the massive galaxy cluster MACS J1423.8+2404 (, MACS J1423 hereafter), one of the most dynamically…
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…
A complex node of the cosmic web associated with the massive galaxy cluster MACS J0600.1-2008
Lukas J. Furtak, Adi Zitrin, Johan P. Richard +18
MACS J0600.1-2008 (MACS0600) is an X-ray luminous, massive galaxy cluster at , studied previously by the REionization LensIng Cluster Survey (RELICS) and ALMA…
