Dark Matter Distribution in Milky Way analog Galaxies

The Astrophysical Journal
Our current understanding of how dark matter (DM) is distributed within the Milky Way (MW) halo, particularly in the solar neighborhood, is based on either careful studies of the local stellar orbits, model assumptions on the global shape of the MW halo,

The density profiles of dark matter halos in spiral galaxies

Natural Science, 2012
In spiral galaxies, we explain their non-Keplerian rotation curves (RCs) by means of a non-luminous component embedding their stellar-gaseous disks. Understanding the detailed properties of this component (labelled Dark Matter, DM) is one of the most pressing issues of Cosmology. We investigate the recent relationship (claimed by Walker et al.

Development, Characterization, and Stability of Burgers With Partial or Total Replacement of Beef by Vegetable Ingredients

Journal of Food Science, Volume 91, Issue 6, June 2026.
ABSTRACT This study evaluated the partial or total replacement of beef (0%, 25%, 50%, 75%, and 100%) with plant‐based ingredients (risotto rice, textured soy protein, and cassava starch) in burgers, combined with the incorporation of freeze‐dried açaí pulp as an antioxidant and natural colorant, and sesame oil as a substitute for beef fat.

Galaxy Galaxy Lensing as a Probe of Galaxy Dark Matter Halos

, 2006
Gravitational lensing has now become a popular tool to measure the mass distribution of structures in the Universe on various scales. Here we focus on the study of galaxy's scale dark matter halos with galaxy-galaxy lensing techniques: observing the shapes of distant background galaxies which have been lensed by foreground galaxies allows us to map the

Minor epic: Notes toward a different “Anthropoetry”

Anthropology and Humanism, Volume 51, Issue 1, June 2026.
Abstract Anthropologists have often turned to poetry as a means of accessing emotional registers of which conventional academic prose is unable to avail. In doing so, they have tacitly conflated poetry with lyric poetry, today probably the most widely practiced poetic genre, associated in particular with the expression of inner feelings and subjectival

Halo Substructure Boosts to the Signatures of Dark Matter Annihilation

Galaxies, 2019
The presence of dark matter substructure will boost the signatures of dark matter annihilation. We review recent progress on estimates of this subhalo boost factor—a ratio of the luminosity from annihilation in the subhalos to that originating the ...

Morphometric and External Injury Characterization of Rainbow Trout (O. mykiss) Used for Stocking in the Alpine River Inn (Bavaria, Germany)

Fisheries Management and Ecology, Volume 33, Issue 3, Page 452-462, June 2026.
ABSTRACT Stocking fish is a common practice in fisheries management, particularly for species of high conservation value or economic importance. Despite its widespread use, systematic evaluation of fish stockings remains scarce. This includes non‐native species such as rainbow trout (Oncorhynchus mykiss), which are intensively stocked into European ...

Probing the Dark Matter Halos of External Galaxies with Stellar Streams

The Astrophysical Journal
Stellar streams have proven to be powerful tools for measuring the Milky Way’s gravitational potential and hence its dark matter (DM) halo. In the coming years, the Vera Rubin Observatory, Euclid, ARRAKIHS, and the Nancy Grace Roman Space Telescope will ...

Line-of-sight Bias in Dark Matter Inferences from Galaxy Cluster Mergers

The Astrophysical Journal
In collisions of galaxy clusters, the lack of displacement between dark matter and galaxies suggests that the dark matter scattering depth is small. This yields an upper limit on the dark matter cross section if the dark matter column density is known ...

Dark matter in ALFALFA galaxies

Astronomy & Astrophysics
Aims. This paper aims to investigate the galaxy-halo connection using a large sample of individual galaxies with H  I -integrated spectra. We determined their dark matter content by applying a dynamical method based on H  I line ...
