We combine DensePak integral field unit and TAURUS Fabry-Perot observations of 13 nuclear rings to show an interconnection between the kinematic properties of...
Nuclear Spirals as Feeding Channels to the Supermassive Black Hole: The Case of the Galaxy NGC 6951
We report the discovery of gas streaming motions along nuclear spiral arms toward the LINER nucleus of the galaxy NGC 6951. The observations, obtained using the...
Nuclear Star Formation Activity and Black Hole Accretion in Nearby Seyfert Galaxies
Recent theoretical and observational works indicate the presence of a correlation between the star-formation rate (SFR) and active galactic nucleus (AGN)...
Nuclear star formation in the hotspot galaxy NGC 2903
We present high-resolution near-infrared imaging obtained using adaptive optics and HST/NICMOS, and ground-based spectroscopy of the hotspot galaxy NGC 2903...
We present calculations that account for the infall of matter onto the heart of a starburst, a condition thought indispensable for causing the large...
Nucleosynthesis and the Inhomogeneous Chemical Evolution of the Carina Dwarf Galaxy
The detailed abundances of 23 chemical elements in nine bright red giant branch stars in the Carina dwarf spheroidal galaxy are presented based on high...
Nueva luz para la imagen más profunda del telescopio Hubble
Un trabajo de casi tres años, realizado por investigadores del Instituto de Astrofísica de Canarias y la Universidad de La Laguna, crea la imagen más profunda...
Nuevos datos sobre el mayor y uno de los más completos anillos de Einstein descubiertos
En diciembre de 2020 el equipo de la Agencia Espacial Europea (ESA) publicó una imagen tomada por el telescopio espacial Hubble de GAL-CLUS-022058s, el anillo...
Numerical simulations of dark matter haloes produce polytropic central cores when reaching thermodynamic equilibrium
Self-gravitating astronomical objects often show a central plateau in the density profile (core) whose physical origin is hotly debated. Cores are theoretically...
