Observational Evidence of Velocity Anisotropy Assembly Bias in Galaxy Clusters
Facundo Rodriguez, Andrea Biviano, Ravi K. Sheth +2
Cosmological simulations show that halo clustering depends on secondary internal properties beyond mass, an effect known as assembly bias. In particular, numerical models have show…
Evolution of submillimeter galaxies across cosmic-web environments
Ankit Kumar, M. Celeste Artale, Antonio D. Montero-Dorta +12
Submillimeter galaxies (SMGs) provide valuable insights into galaxy formation and evolution and are likely influenced by their cosmic environment. However, their rarity makes envir…
Predicting galaxy bias using machine learning
Catalina Riveros-Jara, Antonio D. Montero-Dorta, Natália V. N. Rodrigues +6
Understanding how galaxies trace the underlying matter density field is essential for characterizing the influence of the large-scale structure on galaxy formation, being therefore…
The Galaxy Bias Profile of Cosmic Voids:A Comparison of Void Finders
Ignacio G. Alfaro, Antonio D. Montero-Dorta, Jorge F. Bustillos +6
Cosmic voids, the largest underdense regions in the Universe, provide unique laboratories for studying galaxy formation and constitute powerful probes of cosmology. Recent work has…
Connecting clustering and the cosmic web:Observational constraints on secondary halo bias
Facundo Rodriguez, Antonio D. Montero-Dorta
Cosmological simulations predict significant secondary dependencies of halo clustering on internal properties and environment. Detecting these subtle signals in observational data…
The invariance of group occupation across the cosmic web
Vicente Izzo Dominguez, Facundo Rodriguez, Antonio D. Montero-Dorta
Recent efforts to identify secondary variations in the Halo Occupation Distribution (HOD) have primarily focused on simulations examining the role of large-scale cosmic environment…
