TranQuiL: Long Range Detection and Localization of Interference in Radio Quiet Zones

Radio Science, Volume 61, Issue 1, January 2026.
Abstract Radio Quiet Zones (RQZs) have been established to prevent radio sources from causing harmful interference to sensitive radio telescopes, which study extremely faint cosmic radio waves. Even with strict regulations, such interference is growing due to the widespread use of consumer electronics, emitting in many different frequency bands ...

Polycyclic aromatic hydrocarbons in the dwarf galaxy IC 10

, 2011
Infrared observations from the Spitzer Space Telescope archive are used to study the dust component of the interstellar medium in the IC~10 irregular galaxy. Dust distribution in the galaxy is compared to the distributions of H$\alpha$ and [SII] emission,

The Stellar Velocity Dispersion in the Inner 1.3 Disk Scale Lengths of the Irregular Galaxy NGC 4449 [PDF]

, 2005
We present measurements of the stellar velocity dispersion in the inner 1' radius (1.3 disk scale lengths) of the irregular galaxy NGC 4449 determined from long-slit absorption-line spectra.

Fast, Flexible, Feasible: A Transparent Framework for Evaluating eDNA Workflow Trade‐Offs in Resource‐Limited Settings

Molecular Ecology Resources, Volume 26, Issue 1, January 2026.
ABSTRACT Environmental DNA (eDNA) analysis enables biodiversity monitoring by detecting organisms from trace genetic material, but high reagent costs, cold‐chain logistics and computational demands limit its broader use, particularly in resource‐limited settings.

Weaponising the Supply Chain: Yemen's Blockade and the Contradictions of Maritime Logistics Capital

Antipode, Volume 58, Issue 1, January 2026.
Abstract This paper examines the 2023–2025 naval blockade imposed by Yemen in the Red Sea. It argues that the blockade's success in disrupting global trade stemmed from the potent confluence of asymmetric military tactics and the structural vulnerabilities inherent within global maritime logistics capitalism.

Ultradeep Imaging of Nearby Dwarf Irregular Galaxies: Young Objects in the Far Outer Disk

The Astronomical Journal
Ultradeep UBVI imaging of 10 nearby (≤7.8 Mpc) noninteracting dwarf irregular galaxies are used to examine their far outer stellar disks. The annulus between 26 mag arcsec ^−2 and 29 mag arcsec ^−2 in the V band is what we define as the far outer disk ...

The Local Group Census: planetary nebulae in Sextans B

, 2002
Five planetary nebulae (PNe) have been discovered in the nearby dwarf irregular galaxy. Emission line images were obtained using the Wide Field Camera of the 2.5m Isaac Newton Telescope (INT) at La Palma (Spain).
