The Spatial Distribution of Globular Cluster Systems in Early Type Galaxies: Estimation Procedure and Catalog of Properties for Globular Cluster Systems Observed with Deep Imaging Surveys
Sungsoon Lim, Eric W. Peng, Patrick Côté +18
We present an analysis of the spatial distribution of globular cluster (GC) systems of 118 nearby early-type galaxies in the Next Generation Virgo Cluster Survey (NGVS) and Mass As…
Dwarf Galaxies in the MATLAS Survey: The satellite system of NGC474 under scrutiny with MUSE
Oliver Müller, Francine R. Marleau, Nick Heesters +12
A recent study of the distribution of dwarf galaxies in the MATLAS sample in galaxy groups revealed an excess of flattened satellite structures, reminiscent of the co-rotating plan…
Multi-scale gridded Gabor attention for cirrus segmentation
Felix Richards, Adeline Paiement, Xianghua Xie +2
In this paper, we address the challenge of segmenting global contaminants in large images. The precise delineation of such structures requires ample global context alongside unders…
Panoptic Segmentation of Galactic Structures in LSB Images
Felix Richards, Adeline Paiement, Xianghua Xie +2
We explore the use of deep learning to localise galactic structures in low surface brightness (LSB) images. LSB imaging reveals many interesting structures, though these are freque…
Why do different early-type-galaxies have different amounts of rotational support?
Michal Bilek, Pierre-Alain Duc, Elisabeth Sola
Early-type galaxies (ETGs, i.e. elliptical and lenticular galaxies) differ in their amount of rotational support -- some are purely supported by velocity dispersion, while others s…
The Next Generation Virgo Cluster Survey (NGVS). XXVII.The Size and Structure of Globular Cluster Systems and their Connection to Dark Matter Halos
Sungsoon Lim, Eric W. Peng, Patrick Côté +18
We study the size and structure of globular clusters (GC) systems of 118 early-type galaxies from the NGVS, MATLAS, and ACSVCS surveys. Fitting Sérsic profiles, we investigate the…
