The Fate of Globular Cluster Substructure: A Kinematic Response to Galaxy Assembly
Finn A. Pal, Sarah L. Martell, Elizabeth J. Iles
Globular clusters (GCs) are powerful tracers of galaxy assembly, frequently used to identify accreted substructure and reconstruct hierarchical merger histories. With advances in G…
Bar Properties and Star-by-Star Bar Membership via Action Conservation
Elizabeth J. Iles, Finn A. Pal, Joss Bland-Hawthorn +1
A bar-like central feature is commonly observed in both nearby and distant spiral-type galaxies, including the Milky Way. While many methods exist to categorise this morphology, no…
Measuring the evolution of stellar bars with the host galaxy's spin
Robin Joshi, Scott M. Croom, Stefania Barsanti +3
We examine to what extent the galaxy spin parameter proxy () is affected by bar formation and how it is related to the strong and weak classifications of stellar bars. By cre…
Clues from --A null test designed for line intensity mapping cross-correlation studies
Debanjan Sarkar, Ella Iles, Adrian Liu
Estimating the auto power spectrum of cosmological tracers from line-intensity mapping (LIM) data is often limited by instrumental noise, residual foregrounds, and systematics. Cro…
findAbar: how astronomers may perceive the bar in galaxies differently
Elizabeth J. Iles, Joss Bland-Hawthorn, Courtney Crawford +18
Bars are ubiquitous morphological features in the observed distribution of galaxies. There are similarly many methods for classifying these features and, without a strict theoretic…
Resonant axion and dark photon production in magnetic white dwarfs
Nirmalya Brahma, Ella Iles, Hugo Schérer +1
Using magnetic white dwarfs as a case study, we show that the emission of sub-MeV bosons from stellar plasmas can be substantially modified in the presence of a magnetic field. In…
