It is shown on the basis of a complete sample of Virgo cluster galaxies and a larger set of varied data from the literature that ellipticals, early-type dwarfs...
On the basis of a sample of Virgo cluster galaxies in a larger set of heterogeneous literature data, it is shown that ellipticals, early-type dwarfs, and bulges...
Flares, Warps, Truncations, and Satellite: The Ultra-thin Galaxy UGC 11859
The structure of the outskirts of galaxies provides valuable information about their past and evolution. Due to their projected orientation, edge-on isolated...
Galaxias enanas: laboratorios privilegiados para el estudio de la materia oscura
La revista Nature Astronomy publica hoy, en su colección de publicaciones y reseñas dedicada a las galaxias enanas, un nuevo artículo escrito por Giuseppina...
Galaxies Going Bananas: Inferring the 3D Geometry of High-redshift Galaxies with JWST-CEERS
The 3D geometries of high-redshift galaxies remain poorly understood. We build a differentiable Bayesian model and use Hamiltonian Monte Carlo to efficiently...
Globular cluster systems and the origin of early-type dwarfs in Virgo
Early-type dwarfs (dEs) are by far the most abundant galaxy population in nearby clusters. Whether these objects are primordial, or recent end-products of the...
CCD narrow-band H-alpha photometry of the Sextans A Local Group dwarf irregular galaxy is presented. Fourteen H II regions have been recorded. Their...
Hunting for VIPERS red nuggets - traces of the past
Vimos Public Extragalactic Redshift Survey (VIPERS) is a spectroscopic survey designed to investigate the spatial distribution of ~90k galaxies on redshift 0.4...
Impact of internal bremsstrahlung on the detection of γ rays from neutralinos
We present a detailed study of the effect of internal bremsstrahlung photons in the context of the minimal supersymmetric standard models and their impact on γ...
