From starburst to quenching: merger-driven evolution of the star formation regimes in a shell galaxy
Shell galaxies make a class of tidally distorted galaxies, characterized by wide concentric arc(s), extending out to large galactocentric distances with sharp outer edges. Recent observations of young massive star clusters in the prominent outer shell of N ...
OXFORD UNIV PRESS2022Minimum Cost Intervention Design for Causal Effect Identification
Negar Kiyavash, Sina Akbari, Seyed Jalal Etesami
Pearl's do calculus is a complete axiomatic approach to learn the identifiable causal effects from observational data. When such an effect is not identifiable, it is necessary to perform a collection of often costly interventions in the system to learn the ...
PMLR2022The GOGREEN survey: dependence of galaxy properties on halo mass a z > 1 and implications for environmental quenching
Pascale Jablonka, Hung-Hsu Chan
We use photometric redshifts and statistical background subtraction to measure stellar mass functions in galaxy group-mass (4.5-8 x 10(13) M-circle dot) haloes at 1 < z < 1.5. Groups are selected from COSMOS and SXDF, based on X-ray imaging and sparse spec ...
OXFORD UNIV PRESS2021ASTErIsM: application of topometric clustering algorithms in automatic galaxy detection and classification
Jean-Paul Richard Kneib, Frédéric Courbin, Danuta Janina Paraficz
We present a study on galaxy detection and shape classification using topometric clustering algorithms. We first use the DBSCAN algorithm to extract, from CCD frames, groups of adjacent pixels with significant fluxes and we then apply the DENCLUE algorithm ...
