Accurate Galaxy Cluster Shear and Mass Calibration for LSST with AnaCal
Conghao Zhou, Xiangchong Li, Hao-Yi Wu +12
The observed abundance of galaxy clusters as a function of mass and redshift provides a powerful route to precision cosmology; a key challenge for cluster cosmology is to establish…
Weak-lensing mass calibration of \emph{Planck} Sunyaev--Zel'dovich clusters with HSC-SSP Year~3
Andrés Alejandro Plazas Malagón, Hironao Miyatake, Surhud More +3
We present a weak gravitational lensing mass calibration of 19 \textit{Planck} Sunyaev--Zel'dovich (SZ) selected galaxy clusters using shape measurements from the Hyper Suprime-Cam…
Brightest Cluster Galaxy ellipticity as proxy for halo shape: Orientation bias, assembly bias, and potential selection effects in SZ-selected clusters
Radhakrishnan Srinivasan, Tae-hyeon Shin, Anja von der Linden +93
The orientation of triaxial galaxy clusters with respect to the line-of-sight is expected to be one of the prime sources of scatter and potential bias in optical observables (e.g.,…
Identifying and Measuring Satellite Streaks in DECam Images
Alexandra Serrano Mendoza, Meredith L. Rawls, Andrés Alejandro Plazas Malagón
The rapid growth of satellite constellations, particularly Starlink, is increasingly affecting ground-based astronomy. In this project, we developed a workflow to detect, identify,…
