Spatially resolved stellar-to-total dynamical mass relation

open access: yesAstronomy & Astrophysics
Context. In our standard cosmological model, galaxy assembly is inherently linked to the hierarchical growth of dark matter halos, which provide the gravitational framework in which highly complex baryonic processes unfold.

HD‐DRUM Rhythmic Training in Huntington's Disease: Feasibility, Motor, and Brain Microstructural Pilot Signals

open access: yesMovement Disorders Clinical Practice, EarlyView.
ABSTRACT Background Rhythmic cuing may benefit motor functions in Huntington's disease (HD) by compensating for the loss of predictive timing associated with basal ganglia degeneration. To our knowledge no remote rhythmic training application has been developed or evaluated that seeks to improve function in HD.

The SAMI Galaxy Survey revisiting Galaxy classification through high-order stellar kinematics. (2017)

open access: yes, 2017
The SAMI instrument and Galaxy Survey is described in detail in Croom+ (2012MNRAS.421..872C) and Bryant+ (2015MNRAS.447.2857B). SAMI is a multi-object integral field spectrograph on the 3.9m Anglo Australian Telescope (AAT).

Galaxy morphology and the stellar-halo mass relation

open access: yes, 2020
We use data from the SDSS DR7 and visual classifications of morphology from the Galaxy Zoo project to show that the scatter in the stellar-halo mass relation correlates with galaxy morphology, such that more massive galaxies at fixed halo mass are mostly spirals. We obtain this same correlation in galaxies from the EAGLE simulation.

Detection of Accretion Shelves Out to the Virial Radius of a Low-mass Galaxy with JWST

open access: yesThe Astrophysical Journal
We report the serendipitous discovery of an extended stellar halo surrounding the low-mass galaxy Ark 227 ( M _* = 5 × 10 ^9 M _⊙ ; d = 35 Mpc) in deep JWST NIRCam imaging from the Blue Jay Survey.

How ventures maintain stakeholder support amidst operational legitimacy threats

open access: yesStrategic Entrepreneurship Journal, EarlyView.
Abstract Research Summary We explore how ventures mitigate operational legitimacy threats—threats that originate within the venture and challenge claims relating to the venture's ability to deliver on its promised value proposition. Through an inductive study of four ventures working to deliver their promised products following successful crowdfunding ...

Creating Stellar Populations in Computational Models of Stellar Halos

open access: yes, 2023
Electronic Thesis or DissertationStellar halos are key to understanding galaxy formation. They extend far away from the disk of the galaxy and preserve its formation history.

Merger-driven Growth of Intermediate-mass Black Holes: Constraints from Hubble Space Telescope Imaging of Hyper-luminous X-Ray Sources

open access: yesThe Astrophysical Journal
Hyper-luminous X-ray sources (HLXs) are extragalactic off-nuclear X-ray sources with luminosities exceeding the theoretical limit for accretion onto stellar-mass compact objects.

Response of Fecal Bacteria and Fungi to Tannin‐Rich Diets in Sika Deer (Cervus nippon): Evidence from Both Feeding Experiments and Field Investigations

open access: yesIntegrative Zoology, EarlyView.
Feeding with tannin‐rich diets altered the fecal microbial composition and increased the relative abundance of tannin‐degrading microbes. We hypothesize that fecal bacteria and fungi may play important roles in helping herbivores adapt to tannin‐rich diets but respond to different tannin concentrations varies.

Longitudinal and cross‐sectional perspectives on elementary school children's post‐error slowing in reading and arithmetic

open access: yesBritish Journal of Educational Psychology, EarlyView.
Abstract Background This study investigated the development of primary school children's error‐related adjustments in reading and arithmetic, both cross‐sectionally and longitudinally. Aims We aimed to uncover monitoring‐based cognitive control processes and often‐overlooked strategy use in academic tasks requiring a balancing of speed and accuracy ...
