DDO 68-C: HST Confirms Yet Another Companion of the Isolated Dwarf Galaxy DDO 68

The Astrophysical Journal
We present the results of deep Hubble Space Telescope photometry of the dwarf galaxy DDO 68-C, proposed as possibly associated with the isolated peculiar dwarf DDO 68.

Morphometric and External Injury Characterization of Rainbow Trout (O. mykiss) Used for Stocking in the Alpine River Inn (Bavaria, Germany)

Fisheries Management and Ecology, EarlyView.
ABSTRACT Stocking fish is a common practice in fisheries management, particularly for species of high conservation value or economic importance. Despite its widespread use, systematic evaluation of fish stockings remains scarce. This includes non‐native species such as rainbow trout (Oncorhynchus mykiss), which are intensively stocked into European ...

When is a Bulge Not a Bulge? Revealing the Satellite Nature of NGC 5474’s Bulge

The Astrophysical Journal
A satellite galaxy of the nearby spiral M101, NGC 5474 has a prominent bulge offset from the kinematic center of the underlying star-forming disk that has gained attention in recent years.

Cowbirds use conspecific social information to detect host nests in the wild

Ibis, EarlyView.
Recent work shows that hosts of avian brood parasites use social information to increase egg rejection rates, but fewer studies explore how parasites themselves use such information to detect host nests in the wild. To determine whether wild Brown‐headed Cowbirds Molothrus ater use social information to detect host nests, we measured how individual ...

The role of peculiar velocity uncertainties in standard siren cosmology

The Open Journal of Astrophysics
Local distance indicators such as standard sirens, in combination with spectroscopic redshift measurements of their host galaxies, allow us to estimate the present-day expansion rate of the Universe parameterised by Hubble's constant, H_0. However, these

Peculiar Red Giants in External Galaxies [PDF]

International Astronomical Union Colloquium, 1989
AbstractStudy of the late-type stellar content in external galaxies provides numerous clues for the theory of stellar evolution, for star-formation scenarios in galaxies, and for proper models of the luminosity evolution of galaxies which are then used in cosmological studies.

The Public Character of Church in the Digital Age☆

International Journal of Systematic Theology, EarlyView.
Abstract The rise of digital technology in recent decades has led to a rapid change of communication and interaction within society and its public dimensions. As this shift in the technological landscape raises theological questions about the appropriate ecclesial use of digital technology, it also touches upon fundamental questions about the church's ...
