Central stellar depletion in the Draco dwarf from Subaru photometry
Eduardo Vitral, Kyosuke S. Sato, Jorge Peñarrubia +2
Dark matter subhaloes are a fundamental prediction of the standard cosmological model, but their low-mass population remains difficult to constrain observationally. Recent work has…
Euclid: Data Release 1 (DR1) -- Fornax-7, an ultra-faint companion to the Fornax dwarf spheroidal galaxy? A remote star cluster or dwarf satellite of the Fornax dSph
T. Saifollahi, A. Lançon, A. M. N. Ferguson +165
We report the discovery of an ultra-faint stellar system in the vicinity of the Fornax dwarf spheroidal (dSph) galaxy in Euclid DR1. This system, which we designate Fornax-7, is lo…
Globular Cluster Systems in Dwarf Galaxies: Catalogs and Comparisons
Veronika Dornan, William E. Harris
The connection between a galaxy's total globular cluster system (GCS) mass and its halo mass has been studied for decades and it has been found that galaxies at nearly all observed…
Major Mergers Mean Major Offset: Drivers of Intrinsic Scatter in The Scaling Relation for Massive Elliptical Galaxies
Veronika Dornan, William E. Harris
In this work we determine the total globular cluster (GC) counts and globular cluster system (GCS) total mass estimates for 27 extremely massive elliptical galaxies. The GC 2D spat…
Utilizing Voronoi Tessellations to Determine Radial Density Profiles
Veronika Dornan, William E. Harris
We have developed a novel method of determining 2D radial density profiles for astronomical systems of discrete objects using Voronoi tessellations. This Voronoi-based method was t…
Investigating the Relation in the Most Massive Galaxies
Veronika Dornan, William E. Harris
The relation between the total mass contained in the globular clusters of a galaxy and the mass of its dark matter halo has been found observationally to be nearly linear over five…
The Effects of Metallicity on Convective Overshoot Behaviour in Models of delta Scuti Variable Stars
V. Dornan, C. C. Lovekin
delta Scuti variables are stars which exhibit periodic changes in their luminosity through radial and non-radial pulsations. Internally, these stars have relatively small convectiv…
