Detection of Accretion Shelves Out to the Virial Radius of a Low-Mass Galaxy with JWST
Charlie Conroy, Benjamin D. Johnson, Pieter van Dokkum +8
We report the serendipitous discovery of an extended stellar halo surrounding the low-mass galaxy Ark 227 (; d=35 Mpc) in deep JWST NIRCam imaging from…
Can we really pick and choose? Benchmarking various selections of Gaia Enceladus/Sausage stars in observations with simulations
Andreia Carrillo, Alis J. Deason, Azadeh Fattahi +2
Large spectroscopic surveys plus Gaia astrometry have shown us that the inner stellar halo of the Galaxy is dominated by the debris of Gaia Enceladus/Sausage (GES). With the richne…
Unravelling the mass spectrum of destroyed dwarf galaxies with the metallicity distribution function
Alis J. Deason, Sergey E. Koposov, Azadeh Fattahi +1
Accreted stellar populations are comprised of the remnants of destroyed galaxies, and often dominate the `stellar haloes' of galaxies such as the Milky Way (MW). This ensemble of e…
The 3D kinematics of stellar substructures in the periphery of the Large Magellanic Cloud
Camila Navarrete, David S. Aguado, Vasily Belokurov +4
We report the 3D kinematics of 27 Mira-like stars in the northern, eastern and southern periphery of the Large Magellanic Cloud (LMC), based on Gaia proper motions and a dedicated…
Energy wrinkles and phase-space folds of the last major merger
Vasily Belokurov, Eugene Vasiliev, Alis J. Deason +5
Relying on the dramatic increase in the number of stars with full 6D phase-space information provided by the Gaia Data Release 3, we discover unambiguous signatures of phase-mixing…
Clouds, Streams and Bridges. Redrawing the blueprint of the Magellanic System with Gaia DR1
Vasily Belokurov, Denis Erkal, Alis J. Deason +5
We present the discovery of stellar tidal tails around the Large and the Small Magellanic Clouds in the Gaia DR1 data. In between the Clouds, their tidal arms are stretched towards…
