The filament of ionized gas in the outskirt of M87
We report on the filament of ionized gas found at the NE periphery of M87, the second brightest elliptical galaxy in the Virgo cluster. The object lies at 3.16...
The filling factor of intergalactic metals at redshift z= 3
Observations of quasar absorption-line systems reveal that the z= 3 intergalactic medium (IGM) is polluted by heavy elements down to H I optical depths τH I≪ 10...
The Filling Factor-Radius Relation for 58 H II Regions across the Disk of NGC 6946
Using the OSIRIS tunable narrowband imager on the 10.4 m GTC (La Palma), we have mapped the SAB(rs)cd galaxy NGC 6946 over a ~7.3 × 7.5 arcmin2 field in the...
The First Billion Years project: birthplaces of direct collapse black holes
We investigate the environment in which direct-collapse black holes may form by analysing a cosmological, hydrodynamical simulation that is part of the First...
The First Billion Years project: constraining the dust attenuation law of star-forming galaxies at z ≃ 5
We present the results of a study investigating the dust attenuation law at z ≃ 5, based on synthetic spectral energy distributions (SEDs) calculated for a...
The First Billion Years project: dark matter haloes going from contraction to expansion and back again
We study the effect of baryons on the inner dark matter profile of the first galaxies using the First Billion Years simulation between z = 16 and 6 before...
The First Billion Years project: Finding infant globular clusters at z = 6
Aims: We aim to conduct an assessment of the demographics of substructures in cosmological simulations to identify low-mass stellar systems at high redshift...
The First Billion Years project: gamma-ray bursts at z > 5
Long gamma-ray burst's (LGRB's) association with the death of massive stars suggests that they could be used to probe the cosmic star formation history (CSFH)...
The First Billion Years project: proto-galaxies reionizing the Universe
The contribution of stars in galaxies to cosmic reionization depends on the star formation history in the Universe, the abundance of galaxies during...
