The stellar mass-halo mass relation of isolated field dwarfs: a critical test of $\Lambda$CDM at the edge of galaxy formation [PDF]

, 2017
We fit the rotation curves of isolated dwarf galaxies to directly measure the stellar mass-halo mass relation ($M_*-M_{200}$) over the mass range $5 \times 10^5 < M_{*}/{\rm M}_\odot < 10^{8}$.

Archives of impact: The politics of craters on Earth

Geographical 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.

What Is Missing from the Local Stellar Halo?

The Astrophysical Journal
The Milky Way’s stellar halo, which extends to >100 kpc, encodes the evolutionary history of our Galaxy. However, most studies of the halo to date have been limited to within a few kiloparsecs of the Sun.

Constraints on the Frequency and Mass Content of r-process Events Derived from Turbulent Mixing in Galactic Disks

The Astrophysical Journal, 2023
Metal-poor stars in the Milky Way (MW) halo display large star-to-star dispersion in their r -process abundance relative to lighter elements. This suggests a chemically diverse and unmixed interstellar medium (ISM) in the early universe.

The turbulent formation of stars

, 2018
How stars are born from clouds of gas is a rich physics problem whose solution will inform our understanding of not just stars but also planets, galaxies, and the universe itself. Star formation is stupendously inefficient. Take the Milky Way. Our galaxy

Whole Blackcurrant (Ribes nigrum) Alleviates High‐Fat Diet Induced‐Obesity and Colonic Inflammation by Modulating the Gut Microbiota in Mice

Molecular Nutrition &Food Research, Volume 70, Issue 7, 15 April 2026.
Obesity caused by a high‐fat diet (HFD) is known to result from interactions between the gut microbiota, intestinal barrier function, and excessive inflammatory responses in the colon. In this study, we found that dietary intake of whole blackcurrants prevented HFD‐induced obesity by restoring gut microbiota dysbiosis, upregulating intestinal barrier ...

Modeling the Accretion of High-velocity Clouds from a Rotating Halo

The Astrophysical Journal
High-velocity clouds (HVCs) are a major fuel reservoir for star formation in the Galactic disk. Determining their origin and kinematics is thus crucial for understanding Galactic evolution.

Simulating Atomic Dark Matter in Milky Way Analogs

The Astrophysical Journal Letters, 2023
Dark sector theories naturally lead to multicomponent scenarios for dark matter where a subcomponent can dissipate energy through self-interactions, allowing it to efficiently cool inside galaxies.

Chemical Abundance Analysis of Tucana III, the Second $r$-process Enhanced Ultra-Faint Dwarf Galaxy [PDF]

, 2019
We present a chemical abundance analysis of four additional confirmed member stars of Tucana III, a Milky Way satellite galaxy candidate in the process of being tidally disrupted as it is accreted by the Galaxy.

Hitchhiker's Guide to the Swampland: The Cosmologist's Handbook to the String‐Theoretical Swampland Programme

Fortschritte der Physik, Volume 74, Issue 4, April 2026.
Abstract String theory has strong implications for cosmology, implying the absence of a cosmological constant, ruling out single‐field slow‐roll inflation, and that black holes decay. The origins of these statements are elucidated within the string‐theoretical swampland programme.
