We report on the 323 hours of nearly uninterrupted time series photometric observations of the DBV star GD 358 acquired with the Whole Earth Telescope (WET)...
WHaD diagram: Classifying the ionizing source with one single emission line
Context. The usual approach to classify the ionizing source using optical spectroscopy is based on the use of diagnostic diagrams that compare the relative...
What boost galaxy mergers in two massive galaxy protoclusters at z = 2.24?
Characterizing the structural properties of galaxies in high-redshift protoclusters is key to our understanding of the environmental effects on galaxy evolution...
What do Simulations Predict for the Galaxy Stellar Mass Function and its Evolution in Different Environments?
We present a comparison between the observed galaxy stellar mass function and the one predicted from the De Lucia & Blaizot semi-analytic model applied to the...
We present a study aimed at understanding the physical phenomena underlying the formation and evolution of galaxies following a data-driven analysis of...
The Sun and other similar (solar-like) stars have an internal magnetic field that can emerge on the surface, forming features such as dark spots, which drive...
The low-mass X-ray binary 4U 0614+091 is a source of sporadic thermonuclear (type I) X-ray bursts. We find bursts with a wide variety of characteristics in...
What is the Milky Way outer halo made of?. High resolution spectroscopy of distant red giants
In a framework where galaxies form hierarchically, extended stellar haloes are predicted to be an ubiquitous feature around Milky Way-like galaxies and to...
What Is the Redshift of the Gamma-ray BL Lac Source S4 0954+65?
High signal-to-noise ratio spectroscopic observations of the BL Lac object S4 0954+65 at the alleged redshift z = 0.367 are presented. This source was detected...
