Off-center nuclei in galaxies

The Astrophysical Journal, 1992
The nucleus of a galaxy orbits around the mass centroid. Orbital motions appear overstable in numerical experiments started with a galaxy's nucleus at rest atop its mass centroid. The amplitude doubles in 6-10 orbital periods. Orbits precess, nutate, and change their amplitudes, but they keep fairly constant periods.

De Novo Assembly and Comparative Analysis of the Complete Mitochondrial Genome of Mesenchytraeus (Annelida, Enchytraeidae)

Ecology and Evolution, Volume 16, Issue 9, September 2026.
This present the first mitochondrial genome dataset for 13 Mesenchytraeus species from the Changbai Mountain glacial refugium. Beyond characterizing standard genomic features, we perform comparative analyses of gene order, nucleotide composition, codon usage, and control region structure.

Radio Nuclei in Nearby Galaxies [PDF]

Symposium - International Astronomical Union, 1984
This review is an attempt to summarize VLBI continuum observations at cm- and dm-wavelengths of active galactic nuclei at distances ≲ 100 Mpc (Ho = 50 km s−1 Mpc−1). ‘Nearby galaxies’, thus defined, are close enough for achieving the highest possible spatial resolution.
