Euclid Quick Data Release (Q1). The role of cosmic connectivity in shaping galaxy clusters
Euclid Collaboration, C. Gouin, C. Laigle +337
The matter distribution around galaxy clusters is distributed over several filaments, reflecting their positions as nodes in the large-scale cosmic web. The number of filaments con…
Sifting for a Stream: The Morphology of the Stellar Stream
Benjamin Cohen, Alexander P. Ji, Peter S. Ferguson +18
Stellar streams are sensitive laboratories for understanding the small-scale structure in our Galaxy's gravitational field. Here, we analyze the morphology of the stellar st…
The influence of the Cosmic Web on the properties of dwarf galaxies in the Fornax-Eridanus Supercluster
X. Xu, P. Ravichandran, R. F. Peletier +4
We analyze a sample of low surface brightness dwarf galaxies (mu_e,g > 24.2 mag arcsec^-2), detected using interpretable machine learning tools from the DES survey. We use the Tano…
: Tidal Disruption in Crater 2 and Formation of Diffuse Dwarf Galaxies in the Local Group
Guilherme Limberg, Alexander P. Ji, Ting S. Li +19
We present results of a spectroscopic campaign around the diffuse dwarf galaxy Crater 2 (Cra2) and its tidal tails as part of the Southern Stellar Stream Spectroscopic Survey ($S^5…
1-DREAM: 1D Recovery, Extraction and Analysis of Manifolds in noisy environments
Marco Canducci, Petra Awad, Abolfazl Taghribi +7
Filaments are ubiquitous in astronomical data sets. Be it in particle simulations or observations, filaments are always tracers of a perturbation in the equilibrium of the studied…
Asymmetry at Low Surface Brightness as an Indicator of Environmental Processes in the Fornax Cluster
X. Xu, R. F. Peletier, P. Awad +2
Dwarf galaxies play an important role in studying the effects of the environment on galaxy formation and evolution. In this study, we aim to explore the relationship between the mo…
