Dissecting Halo Components in IFU Data
Galaxies, 2017 While most astronomers are now familiar with tools to decompose images into multiple components such as disks, bulges, and halos, the equivalent techniques for spectral data cubes are still in their infancy.

Disk‐Bulge‐Halo Models for the Andromeda Galaxy [PDF]
The Astrophysical Journal, 2003 We present a suite of semi-analytic disk-bulge-halo models for the Andromeda galaxy (M31) which satisfy three fundamental conditions: (1) internal self-consistency; (2) consistency with observational data; and (3) stability of the disk against the formation of a central bar. The models are chosen from a set first constructed by Kuijken and Dubinski. We

Astronomische Nachrichten, Volume 346, Issue 9, November 2025.ABSTRACT We present James Webb Space Telescope observations of M 4—the closest globular cluster—that probe the lower Main Sequence down to the hydrogen‐burning limit. The unveiled stellar sequence reaches much fainter luminosities than previously possible, revealing a few extremely red objects that are consistent with brown dwarfs as cool as Teff∼1000K$

The Link between Galaxy Structure Properties and Star Formation in Local Galaxies
The Astrophysical JournalTo investigate the role of morphology in galaxy evolution, we analyze the relationships between galaxy structure, star formation, and H i gas content.

, 2019 Extensive observations of the highly-obscured, inner regions of the Milky Way are being used to disentangle and characterise the chemo-dynamical and morphological properties of the bulge and inner disc components. Simultaneously, state-of-the-art simulations and dedicated observations of nearby galaxies are in place to interpret the nature of the ...

The Merger-driven Formation of Classical Low Surface Brightness Galaxies in Romulus25
The Astrophysical JournalWe use the R omulus 25 cosmological simulation volume to study a large sample of late-type gas-rich galaxies with low central surface brightnesses known as classical low surface brightness (LSB) galaxies and compare them to a mass-matched sample of high ...

Ecology and Evolution, Volume 15, Issue 7, July 2025.Conservation is impossible if we have not described all of the species we aim to conserve. This paper reviews the taxonomy of the kultarr (Antechinomys laniger) a small arid‐zone specialist native to Australia. We describe a new species, A. auritus sp. nov., and resurrect a formerly recognized species, A. spenceri. ABSTRACT Globally, mammal species are

Macromolecular Rapid Communications, Volume 46, Issue 13, July 04, 2025.Multidrug resistant Pseudomonas (P.) aeruginosa is detected in many infected wounds and is challenging to treat with antibiotics. As an alternative, this work incorporates anti‐P. aeruginosa Neko phages into electrospun fibres to explore their potential for treating infected wounds.
