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.

Stellar streams around dwarf galaxies in the local Universe
Astronomy & AstrophysicsContext. While mergers between massive galaxies and their dwarf satellites have been well studied, the properties of dwarf–dwarf satellite mergers are not well constrained.

Overmassive Black Holes in Dwarf Galaxies Out to z ∼ 0.9 in the VIPERS Survey
The Astrophysical Journal Letters, 2023 Supermassive black holes (SMBHs) are thought to originate from early universe seed black holes of mass M _BH ∼ 10 ^2 –10 ^5 M _⊙ and grown through cosmic time. Such seeds could be powering the active galactic nuclei (AGN) found in today’s dwarf galaxies.

The Pointing Error Due To Laser Propagation in Space Plasma for TianQin Gravitational Wave Detection
Space Weather, Volume 24, Issue 4, April 2026.Abstract TianQin, a space‐borne gravitational wave observatory, is designed to detect gravitational‐wave signals via laser interferometry. As the inhomogeneous space plasma surrounds the inter‐satellite laser links, the propagation of the laser in space plasma can introduce pointing error noise.

Molecular hydrogen in galaxies [PDF]
, 1987 This study aims to understand the key role played by molecular hydrogen in the evolution of galaxies, with a view to constraining its radial distribution in the Galaxy and the CO→H(_2) conversion factor α(_20).The star formation rate is shown to be ...

The morphological mix of dwarf galaxies in the nearby Universe [PDF]
We use a complete, unbiased sample of 257 dwarf (10) galaxies at z < 0.08, in the COSMOS field, to study the morphological mix of the dwarf population in low-density environments.

Barley yellow dwarf epidemiology [PDF]
, 2006 Barley yellow dwarf (BYD) disease is induced by viruses that are vectored by aphids. The viruses infect grasses and cause severe damage on oats, barley and wheat worldwide.

The Astrophysical JournalWe present a detailed study of radio-detected dwarf galaxies ( M _⋆ ≲ 3 × 10 ^9 M _⊙ ) to characterize extreme star formation and search for (variable) radio active galactic nuclei (AGNs). Our sample comes from A. E.

Astronomische Nachrichten, Volume 347, Issue 3, March 2026.ABSTRACT Planetary nebulae represent a late evolutionary phase of low‐ to intermediate‐mass stars. In this article, we present the serendipitous discovery of a previously unknown, faint potential Galactic planetary nebula (PN) in the constellation Camelopardalis, identified during a survey‐inspection, aiming at the detection of dwarf companions of the ...
