Mass Dependence of Galaxy–Halo Alignment in LOWZ and CMASS
The Astrophysical Journal, 2023 We measure the galaxy-ellipticity (GI) correlations for the Sloan Digital Sky Survey Data Release 12 LOWZ and CMASS samples with the shape measurements from the DESI Legacy Imaging Surveys.

The extended ‘stellar halo’ of the Ursa Minor dwarf galaxy
Monthly Notices of the Royal Astronomical Society, 2023 ABSTRACT Stellar candidates in the Ursa Minor (UMi) dwarf galaxy have been found using a new Bayesian algorithm applied to Gaia EDR3 data. Five of these targets are located in the extreme outskirts of UMi, from ∼5 to 12 elliptical half-light radii (rh), where rh(UMi) = 17.32 ± 0.11 arcmin, and have been observed with the high-resolution ...

Feedback and the formation of dwarf galaxy stellar haloes [PDF]
Monthly Notices of the Royal Astronomical Society, 2009 Stellar population studies show that low mass galaxies in all environments exhibit stellar halos that are older and more spherically distributed than the main body of the galaxy. In some cases, there is a significant intermediate age component that extends beyond the young disk. We examine a suite of Smoothed Particle Hydrodynamic (SPH) simulations and

Decoding Galactic Merger Histories
Galaxies, 2017 Galaxy mergers are expected to influence galaxy properties, yet measurements of individual merger histories are lacking. Models predict that merger histories can be measured using stellar halos and that these halos can be quantified using observations of

A ‘Universal’ Density Profile for the Outer Stellar Halos of Galaxies [PDF]
Proceedings of the International Astronomical Union, 2016 AbstractThe outer stellar halos of galaxies contain vital information about the formation history of galaxies, since the relaxation timescales in the outskirts are long enough to keep the memory, while the information about individual formation events in the central parts has long been lost due to mixing, star formation and relaxation.

Studying stellar halos with future facilities [PDF]
, 2016 Stellar halos around galaxies retain fundamental evidence of the processes which lead to their build up. Sophisticated models of galaxy formation in a cosmological context yield quantitative predictions about various observable characteristics, including
