JWST Imaging of the Closest Globular Clusters—VI. The Lowest‐Mass Objects in M 4 and the Galactic Bulge

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$

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

Bulges in nearby galaxies: Linking the properties of the bulge of the MW with those of external galaxies

, 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 ...

Cryptic Kultarr: Integrative Taxonomy Reveals Unrecognized Species of Carnivorous Marsupial (Dasyuridae: Antechinomys) in Arid Australia

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

Anti‐Pseudomonas Aeruginosa Bacteriophage Loaded Electrospun Fibers for Antibacterial Wound Dressings

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.

Plant‐Based Mycetoma Inhibitors Targeting the 50S Ribosomal Protein of Nocardia brasiliensis: In Silico Approach

ChemistrySelect, Volume 10, Issue 21, June 4, 2025.
In‐silico drug discovery pipeline for Mycetoma caused by Nocardia brasiliensis. A library of 1034 phytocompounds was screened to identify potent inhibitors, with Parviflorone F showing strong binding and stability against the 50S ribosomal unit. Molecular dynamics confirmed its inhibitory potential, offering a promising therapeutic candidate.

Mesenchymal Stem Cells Prevent SLC39A14‐Dependent Hepatocyte Ferroptosis through Exosomal miR‐16‐5p in Liver Graft

Advanced Science, Volume 12, Issue 6, February 10, 2025.
In hepatic IRI, SLC39A14 is identified as a driver of hepatocyte ferroptosis through facilitating extracellular NTBI transported into hepatocytes. Furthermore, hBMSCs has a significant therapeutic effect against hepatic IRI. hBMSCs delivered exosomal miR‐16‐5p, which can specifically target the 3'UTR region of SLC39A14 mRNA, thereby inhibiting SLC39A14‐

Resolved properties of classical bulge and pseudo-bulge galaxies

Monthly Notices of the Royal Astronomical Society
ABSTRACT We compare properties of classical and pseudo-bulges and properties of their hosting galaxies selected from the MaNGA survey. Bulge types are identified based on the Sérsic index n of bulge component and the position of bulges on the Kormendy diagram.

JWST Imaging of the Closest Globular Clusters—V. The White Dwarfs Cooling Sequence of M4

Astronomische Nachrichten, Volume 346, Issue 2, February 2025.
ABSTRACT We combine infrared (IR) observations collected by the James Webb Space Telescope with optical deep images by the Hubble Space Telescope taken ~20 years earlier to compute proper‐motion membership for the globular cluster (GC) M4 (NGC 6121) along its entire white dwarf (WD) cooling sequence (CS).
