Influence of the large-scale structure velocity field on halo mass assembly within cosmic filaments
Dannaé Díaz-Axtle, Petra Awad, Divya Rana +1
The cosmic web governs the growth of dark matter halos through anisotropic matter flows, yet the role of local velocity-field dynamics in halo mass assembly remains poorly understo…
Euclid: Quick Data Release (Q1) -- Exploring the detailed visual morphology of galaxies in clusters
P. Mas-Buitrago, S. Kruk, D. O'Ryan +167
Galaxy clusters provide unique laboratories for studying environmental effects on galaxy evolution. The morphology--density (--) and morphology--cluster-centric radius (--…
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…
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…
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…
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…
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…
: New insights from deep spectroscopic observations of the tidal tails of the globular clusters NGC 1261 and NGC 1904
Petra Awad, Ting S. Li, Denis Erkal +22
As globular clusters (GCs) orbit the Milky Way, their stars are tidally stripped forming tidal tails that follow the orbit of the clusters around the Galaxy. The morphology of thes…
The large-scale structure around the Fornax-Eridanus Complex
Maria Angela Raj, Petra Awad, Reynier F. Peletier +7
Our objectives are to map the filamentary network around the Fornax-Eridanus Complex and probe the influence of the local environment on galaxy morphology. We employ the novel mach…
CAVITY, Calar Alto Void Integral-field Treasury surveY and project extension
I. Pérez, S. Verley, L. Sánchez-Menguiano +58
We have learnt in the last decades that the majority of galaxies belong to high density regions interconnected in a sponge-like fashion. This large-scale structure is characterised…
Euclid: Early Release Observations -- Overview of the Perseus cluster and analysis of its luminosity and stellar mass functions
J. -C. Cuillandre, M. Bolzonella, A. Boselli +199
The Euclid ERO programme targeted the Perseus cluster of galaxies, gathering deep data in the central region of the cluster over 0.7 square degree, corresponding to approximately 0…
Euclid: Early Release Observations -- Programme overview and pipeline for compact- and diffuse-emission photometry
J. -C. Cuillandre, E. Bertin, M. Bolzonella +260
The Euclid ERO showcase Euclid's capabilities in advance of its main mission, targeting 17 astronomical objects, from galaxy clusters, nearby galaxies, globular clusters, to star-f…
Swarming in stellar streams: Unveiling the structure of the Jhelum stream with ant colony-inspired computation
Petra Awad, Marco Canducci, Eduardo Balbinot +8
The halo of the Milky Way galaxy hosts multiple dynamically coherent substructures known as stellar streams that are remnants of tidally disrupted systems such as globular clusters…
Probing compact dark matter objects with microlensing in gravitationally lensed quasars
Petra Awad, James H. H. Chan, Martin Millon +2
The microlensing signal in the light curves of gravitationally lensed quasars can shed light on the dark matter (DM) composition in their lensing galaxies. Here, we investigate a s…
Swarm Intelligence-based Extraction and Manifold Crawling Along the Large-Scale Structure
Petra Awad, Reynier Peletier, Marco Canducci +6
The distribution of galaxies and clusters of galaxies on the mega-parsec scale of the Universe follows an intricate pattern now famously known as the Large-Scale Structure or the C…
