The three major spiral galaxies in the Local Group are known to be warped. The question is investigated of whether or not these three warps are aligned. Using...

PublicationThe origin of bulges and discs in the CALIFA survey - I. Morphological evolution
This series of papers aims at understanding the formation and evolution of non-barred disc galaxies. We use the new spectro-photometric decomposition code, C2D...

PublicationThe origin of extended disc galaxies at z = 2
Galaxy formation models typically assume that the size and rotation speed of galaxy discs are largely dictated by the mass, concentration and spin of their...

PublicationThe origin of stars in the inner 500 parsecs in TNG50 galaxies
We investigate the origin of stars in the innermost 500 pc of galaxies spanning stellar masses of $5\times 10^{8-12}\, \mathrm{M}_{\odot }$ at z = 0 using the...

PublicationThe Origin of the 300 km s‑1 Stream near Segue 1
We present a search for new members of the 300 km s‑1 stream (300S) near the dwarf galaxy Segue 1 using wide-field survey data. We identify 11 previously...

NewsThe origin of the first structures formed in galaxies like the Milky Way identified
An international team of scientists led from the Centre for Astrobiology (CAB, CSIC-INTA), with participation from the Instituto de Astrofísica de Canarias (IAC...

PublicationThe origin of the ionization of the diffuse interstellar medium in spiral galaxies. I. Photometric measurements
We present a complete study of the diffuse ionized gas (DIG) in a sample of six spiral galaxies (NGC 157, NGC 3359, NGC 3631, NGC 6764, NGC 6951, NGC 7479)...

PublicationThe origin of the ionization of the diffuse ionized gas in spirals. II. Modelling the distribution of ionizing radiation in NGC 157
In this paper we make a quantitative study of the hypothesis that the diffuse Hα emitted from the discs of spiral galaxies owes its origin to the ionizing...

PublicationThe origin of the IR emission of low-luminosity AGN
To test recent suggestions that the infrared emission of low-luminosity AGN arises in a truncated thin accretion disk, we compare recent, high-resolution IR...
