The equal norm Grassmannian: topology and applications to frame fields
Samuel A. Ballas, Ferhat Karabatman, Tom Needham +1
Given an orientable rank- vector bundle over a -manifold, the Euler class is the unique obstruction to finding a nowhere-zero section. An equal norm Parseval frame is a certa…
Cluster Ages to Reconstruct the Milky Way Assembly (CARMA). VI. The age-metallicity relation of in-situ clusters and the age of the Universe
Chiara Zerbinati, Davide Massari, Fernando Aguado-Agelet +11
Within the homogeneous framework for the derivation of GC ages defined by the CARMA collaboration, we focus on the clusters born in-situ in the MW. As they are the oldest among the…
Cluster Ages to Reconstruct the Milky Way Assembly (CARMA). V. The chronological merger tree of the Milky Way
Fernando Aguado-Agelet, Chiara Zerbinati, Davide Massari +9
We present a new age determination of 24 globular clusters (GCs) dynamically associated with the main accretion events experienced by the Milky Way (MW), as part of the Cluster Age…
The Hubble Missing Globular Cluster Survey. III. Astro-photometric catalogs, artificial-star tests, and improved absolute proper motions
M. Libralato, A. Bellini, D. Massari +17
The Hubble Missing Globular Cluster Survey (MGCS) has taken one of the last opportunities to complete the census of Galactic globular clusters (GCs) started by past Hubble Space Te…
