Red Galaxy Growth and the Halo Occupation Distribution

open access: yes, 2008
We have traced the past 7 Gyr of red galaxy stellar mass growth within dark matter halos. We have determined the halo occupation distribution, which describes how galaxies reside within dark matter halos, using the observed luminosity function and ...

GOES‐R Series X‐Ray Sensor (XRS): 2. On‐Orbit Measurements and Calibrations

open access: yesJournal of Geophysical Research: Space Physics, Volume 131, Issue 5, May 2026.
Abstract An X‐Ray Sensor (XRS) has been onboard each of the National Oceanic and Atmospheric Administration (NOAA) Geostationary Operational Environmental Satellites (GOES) since 1975. XRS measures full‐disk soft X‐ray irradiance in two wavelength bands, 0.05–0.4 nm and 0.1–0.8 nm.

From Halos to Galaxies. IX. Estimate of Halo Assembly History for SDSS Galaxy Groups

open access: yesThe Astrophysical Journal
The properties of the galaxies are tightly connected to their host halo mass and halo assembly history. Accurate measurement of the halo assembly history in observation is challenging but crucial to the understanding of galaxy formation and evolution ...

Archives of impact: The politics of craters on Earth

open access: yesGeographical Research, Volume 64, Issue 2, May 2026.
This paper examines Earth’s 195 confirmed impact craters as archives, exploring their cataloguing and presentation as heritage sites. It argues Western scientific framings using military language and emphasising catastrophe overlook settler colonialism’s violent histories and marginalise indigenous earth‐sky cosmologies.

The Impact of Galaxy-halo Size Relations on Galaxy Clustering Signals

open access: yesThe Open Journal of Astrophysics
Galaxies come in different sizes and morphologies, and these differences are thought to correlate with properties of their underlying dark matter halos.

Evaluating the Color of Chocolate Chip Cookies: Comparative Performance of Instrumental Colorimetry, Digital Image Analysis, and Computer Vision Relative to Human Perception

open access: yesJournal of Food Science, Volume 91, Issue 5, May 2026.
ABSTRACT Food color is commonly quantified using colorimeters; however, these instruments may be impractical in home‐based or small‐scale production settings. More accessible alternatives, such as digital image analysis and computer vision, may offer reliable color quantification when conventional instrumentation is unavailable.

The DREAMS Project: Disentangling the Impact of Halo-to-halo Variance and Baryonic Feedback on Milky Way Dark Matter Density Profiles

open access: yesThe Astrophysical Journal
In this work, we utilize a new suite of Milky Way–mass halos from the DREAMS Project, simulated with cold dark matter (CDM), to quantify the influence of baryon feedback and intrinsic halo-to-halo variance on dark matter density profiles.

Probing Hot Gas in Galaxy Groups through the Sunyaev-Zeldovich Effect

open access: yes, 2011
We investigate the potential of exploiting the Sunyaev-Zeldovich effect (SZE) to study the properties of hot gas in galaxy groups. It is shown that, with upcoming SZE surveys, one can stack SZE maps around galaxy groups of similar halo masses selected ...

Environmental Enrofloxacin Exposure as a Modifiable Driver of Mitochondria‐Mediated Intestinal Aging and Barrier Dysfunction

open access: yesAging Cell, Volume 25, Issue 5, May 2026.
Environmentally relevant enrofloxacin accelerates intestinal aging by impairing epithelial mitochondrial function, disrupting barrier integrity, and reshaping the gut microbiota. Mitochondrial restoration with pyrroloquinoline quinone alleviates hypoxia, inflammation, and gut damage.

On the Pseudo Phase-space Density of Dark Matter Haloes and the Universality of Density Profiles

open access: yesOpen Astronomy, 2015
We examine the radial dependence of the pseudo phase-space density, ρ(r)/σ3(r), for structures on galactic and galaxy cluster scales. We find that it is approximately a power-law only in the range of halo radius resolved by current simulations (down to 0.
