Dark Matter in Fractional Gravity III: Dwarf Galaxies Kinematics [PDF]

, 2023
Recently, we put forward a framework where the dark matter (DM) component within virialized halos is subject to a non-local interaction originated by fractional gravity (FG) effects.

The effect of simulated intergroup encounters on movement patterns and home range use in banded mongooses

Wildlife Biology, Volume 2026, Issue 3, May 2026.
Intergroup conflicts have a wide range of impacts, including affecting movement and ranging patterns. Previous studies found contrasting movement responses to intergroup conflicts, but no explanation for these differences has been suggested. However, these can be broadly grouped into ‘conflict avoidance' responses: avoiding areas close to the fight ...

A MARVEL-ous Study of How Well Galaxy Shapes Reflect Dark Matter Halo Shapes in Cold Dark Matter Simulations

The Astrophysical Journal
We present a 3D shape analysis of both dark matter (DM) and stellar matter (SM) in simulated dwarf galaxies to determine whether stellar shape traces DM shape. Using 80 central and satellite dwarf galaxies from three simulation suites (“Marvelous Massive

Black holes in the low-mass galaxy regime

Astronomy & Astrophysics
Context. Active galactic nuclei (AGNs) have been observed in dwarf galaxies, yet the impact of black hole feedback in these low-mass systems remains unclear. Aims.

Hunting strategies, success, and sustainability: A case study in a community forest on the edge of Salonga National Park, DRC

Ecological Solutions and Evidence, Volume 7, Issue 2, April–June 2026.
In Central Africa, traditional hunting is central to the way of life of local communities. However, increasing demand for wild meat has raised concerns about the sustainability of this practice. With a year‐long analysis of hunting strategies and their impact at the outskirts of Salonga National Park, Democratic Republic of the Congo, we showed a ...

Substructure in Dwarf Galaxies [PDF]

, 2015
Recent years have seen a series of large-scale photometric surveys with the aim of detecting substructure in nearby dwarf galaxies. Some of these objects display a varying distribution of each stellar population, reflecting their star formation histories.

Environmental effects on associations of dwarf galaxies [PDF]

, 2023
We study the properties of associations of dwarf galaxies and their dependence on the environment. Associations of dwarf galaxies are extended systems composed exclusively of dwarf galaxies, considering as dwarf galaxies those galaxies less massive than $

The Formation of Dwarf Galaxy Disks

The Astrophysical Journal
Dwarf galaxies are dark matter-dominated systems that are sensitive to feedback and display a diversity of baryonic morphologies. This makes them excellent probes for understanding dark matter and galaxy evolution.

HST UV Spectroscopy of the Dwarf Starburst Galaxy Pox 186

The Astrophysical Journal, 2023
Studying the galaxies responsible for reionization is often conducted through local reionization-era analogs; however, many of these local analogs are too massive to be representative of the low-mass star-forming galaxies that are thought to play a ...

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.
