The Milky Way’s Rowdy Neighbors: The Effects of the Large Magellanic Cloud and Sagittarius Dwarf on the Milky Way Disk

The Astrophysical Journal
The Milky Way (MW) is a barred spiral galaxy shaped by tidal interactions with its satellites. The Large Magellanic Cloud (LMC) and the Sagittarius dwarf galaxy (Sgr) are the dominant influences at the present day. This paper presents a suite of four 10 ^

Lessons from the Local Group (and beyond) on dark matter

, 2014
(Abridged) The existence of exotic dark matter particles outside the standard model of particle physics constitutes a central hypothesis of the current standard model of cosmology (SMoC).

The Science of Galaxy Formation [PDF]

, 2008
Our knowledge of the Universe remains discovery-led: in the absence of adequate physics-based theory, interpretation of new results requires a scientific methodology.

The Bochum Survey of the Southern Galactic Disk: III. Complete Data Release

Astronomische Nachrichten, Volume 347, Issue 3, March 2026.
ABSTRACT The Southern Galactic Disk Survey (GDS) monitored a mosaic of 268 fields along a 6°$$ {6}^{{}^{\circ}} $$‐wide stripe in the southern Galactic disk with simultaneous observations in r′$$ {r}^{\prime } $$ and i′$$ {i}^{\prime } $$ (7m≲r′,i′≲18m$$ {7}^{\mathrm{m}}\lesssim {r}^{\prime },{i}^{\prime}\lesssim {18}^{\mathrm{m}} $$) from September ...

Inverse Compton Contribution to the Star-Forming Extragalactic Gamma-Ray Background

, 2012
Fermi has resolved several star-forming galaxies, but the vast majority of the star-forming universe is unresolved and thus contributes to the extragalactic gamma ray background (EGB). Here, we calculate the contribution from star-forming galaxies to the

Human Eye Visualization With an Attention Mechanism: Enhancing Flower Detection and Classification With Visual Attention and Photometric Principles Inspired by Human Vision

Engineering Reports, Volume 8, Issue 3, March 2026.
The graphical abstract illustrates a flower classification model relying on the human visual system. The model captures images, simulates visual attention and photometric perception, extracts features of shape and color, and classifies flowers by using an optimized neural network that enhances recognition accuracy by mimicking the human eye's focusing ...

NNMT Orchestrates Metabolic‐Epigenetic Reprogramming to Drive Macrophage‐Myofibroblast Transition in Hypertrophic Scarring

Advanced Science, Volume 13, Issue 11, 23 February 2026.
In macrophage‐myofibroblast transition, upregulated NNMT depletes S‐Adenosylmethionine‌ (SAM) and nicotinamide adenine dinucleotide(NAD+), thereby triggering epigenetic reprogramming via Histone H3 Lysine 27 acetylation (H3K27ac) accumulation at the promoter region of master transcription factor Prrx1.

An Empirical Consistent Redshift Bias: A Possible Direct Observation of Zwicky’s TL Theory

Particles
Recent advancements have shown tensions between observations and our current understanding of the Universe. Such observations may include the H0 tension and massive galaxies at high redshift that are older than traditional galaxy formation models have ...

Observing the very low-surface brightness dwarfs in a deep field in the VIRGO cluster: constraints on Dark Matter scenarios [PDF]

, 2017
We report the discovery of 11 very faint (r< 23), low surface brightness ({\mu}_r< 27 mag/arcsec^2) dwarf galaxies in one deep field in the Virgo cluster, obtained by the prime focus cameras (LBC) at the Large Binocular Telescope (LBT).

Enhancing Wholemeal Bread Shelf Life Using Optimized Mixtures of Cinnamon, Clove, and Bay Leaf Essential Oils

Chemistry &Biodiversity, Volume 23, Issue 1, January 2026.
ABSTRACT This study evaluated the preservative potential of essential oils (EOs) in bakery products by identifying fungal contaminants in bread, testing the in vitro antifungal activity of a mixture of cinnamon, clove, and bay leaf EOs, and assessing their effectiveness in extending shelf life. Fungal identification revealed the presence of Penicillium,
