Searching for and characterizing halo substructures with the GALAH DR4 survey
Iryna Kushniruk, Kristopher Youakim, Karin Lind +12
Recent studies show that the Milky Way stellar halo is composed of populations of different origins, shaped by multiple accretion events. To better understand the formation of the…
Tidal debris from Omega Centauri discovered with unsupervised machine learning
Kris Youakim, Karin Lind, Iryna Kushniruk
The gravitational interactions between the Milky Way and in-falling satellites offer a wealth of information about the formation and evolution of our Galaxy. In this paper, we expl…
The HR 1614 moving group is not a dissolving cluster
Iryna Kushniruk, Thomas Bensby, Sofia Feltzing +3
The HR 1614 overdensity in velocity space and has for a long time been known as an old (~2 Gyr) and metal-rich ([Fe/H]~0.2) nearby moving group that has a dissolving cluster origin…
Disentangling the Arcturus stream
Iryna Kushniruk, Thomas Bensby
The Arcturus stream is an over-density of stars in velocity space and its origin has been much debated recently without any clear conclusion. Resolving the nature of the Arcturus s…
Kinematic structures of the Solar neighbourhood revealed by Gaia DR1/TGAS and RAVE
Iryna Kushniruk, Thiebaut Schirmer, Thomas Bensby
The velocity distribution of stars in the Solar neighbourhood is inhomogeneous and rich with stellar streams and kinematic structures. These may retain important clues of the forma…
