We present a spatially resolved study of the ionized gas in the central 2 kpc of the Seyfert 2 galaxy NGC 2110 and investigate the role of its moderate-luminosity radio jet (kinetic radio power of P jet = 2.3 × 10 43 erg s −1). We used new optical integral-field observations taken with the MEGARA spectrograph at the Gran Telescopio Canarias, which

Context. Magnetic reconnection is a fundamental mechanism in astrophysics. A common challenge in mimicking this process numerically in particular for the Sun is that the solar electrical resistivity is small compared to the diffusive effects caused by the discrete nature of codes. Aims: We aim to study different anomalous resistivity models and

We continue our series of papers on phase-space distributions of stars in the Milky Way based on photometrically derived metallicities and Gaia astrometry, with a focus on the halo-disk interface in the local volume. To exploit various photometric databases, we develop a method of empirically calibrating synthetic stellar spectra based on a

We present a new homogeneous survey of VLT/FLAMES LR8 line-of-sight radial velocities (v los) for 1604 resolved red giant branch stars in the Sculptor dwarf spheroidal galaxy. In addition, we provide reliable Ca II triplet metallicities, [Fe/H], for 1339 of these stars. From this combination of new observations (2257 individual spectra) with ESO

Triple-active galactic nucleus (AGN) systems are expected to be the result of the hierarchical model of galaxy formation. Since there are very few of them confirmed as such, we present the results of a new study of the triple AGN candidate SDSS J102700.40+174900.8 (center nucleus) through observations with the GTC-MEGARA Integral Field Unit. 1D and

La constante de Hubble (H0) es un parámetro crítico en cosmología que define propiedades esenciales del universo, como su tamaño, edad, tasa de expansión y densidad crítica. A pesar de su importancia, determinar un valor preciso para H0 sigue siendo un tema de debate en el campo de la cosmología. Se han utilizado varios métodos para medir H0 dentro
