In large-scale cosmological hydrodynamic simulations simplified sub-grid models for gas accretion on to black holes and AGN feedback are commonly used. Such...
A recent determination of the relationships between the X-ray luminosity of the ISM (L X) and the stellar and total mass for a sample of nearby early-type...
Context. The flat-spectrum radio quasar 4C +71.07 is a high-redshift (z = 2.172), γ-loud blazar whose optical emission is dominated by thermal radiation from...
We present measurements of broad emission lines and virial estimates of supermassive black hole masses (M BH) for a large sample of ultrahard X-ray-selected...
The most standard scenario for the evolution of massive galaxies across cosmic time assumes a correspondence based on the interplay between active galactic...
We combine observational data on a dozen independent cosmic properties at high-z with the information on reionization drawn from the spectra of distant luminous...
Un estudio, liderado por la investigadora del Instituto de Astrofísica de Canarias (IAC) Anelise Audibert, revela uno de los procesos que explican la peculiar...
Los agujeros negros en los centros de las galaxias son los objetos más enigmáticos del Universo, no solo por la gigantesca cantidad de material que albergan...
Un equipo internacional de astrónomos ha identificado una rara clase de galaxias que emiten rayos gamma, conocidas como BL Lacertae, dentro de los primeros 2...
