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...
The origin of the intracluster light in The Three Hundred simulations
We investigated the origin and formation mechanisms of the intracluster light (ICL) in THE THREE HUNDRED simulations, a set of 324 hydrodynamically resimulated...
The 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)...
The 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...
The origin of the planetary nebula M 1-16. A morpho-kinematic and chemical analysis
We investigated the origin of the Planetary Nebula (PN) M 1-16 using narrow-band optical imaging, and high- and low-resolution optical spectra to perform a...
The origin of the reversed granulation in the solar photosphere
Aims:We study the structure and reveal the physical nature of the reversed granulation pattern in the solar photosphere by means of 3-dimensional radiative...
The OTELO survey as a morphological probe. Last ten Gyr of galaxy evolution. The mass-size relation up to z = 2
Context. The morphology of galaxies provide us with a unique tool for relating and understanding other physical properties and their changes over the course of...
The OTELO survey. A case study of [O III] λ4959,5007 emitters at ⟨z⟩ = 0.83
Context. The OSIRIS Tunable Filter Emission Line Object (OTELO) survey is a very deep, blind exploration of a selected region of the Extended Groth Strip and is...
