Description
We present 16600 equivalent widths (EWs) in the spectra of 100 and 94 stars with and without known planets, respectively. We have measured line-by-line EWs of about 80 spectral lines for the refractory elements Si, Ca, Sc, Ti, V, Cr, Mn, Co, Ni. The EWs of about 14 lines of Na, Mg and Al in 53 new comparison spectra have been added to the previous analysis by Beirao et al. (2005A&A...438..251B). For each spectral a Gaussian fit was performed using the "splot" task within the "echelle" IRAF package. In order to measure automatically the EWs of Na, Mg and Al lines in the new spectra, we employed a new program (IRAF scripts) written by N.C. Santos (Santos et al., 2005A&A...437.1127S). Each measurement was taken carefully achieving the best agreement between line profiles and Gaussian fits. (3 data files).

    Generating galaxy clusters mass density maps from mock multiview images via deep learning
    Galaxy clusters are composed of dark matter, gas and stars. Their dark matter component, which amounts to around 80% of the total mass, cannot be directly observed but traced by the distribution of diffused gas and galaxy members. In this work, we aim to infer the cluster's projected total mass distribution from mock observational data, i.e. stars

    A machine learning method to infer clusters of galaxies mass radial profiles from mock Sunyaev-Zel'dovich maps with The Three Hundred clusters
    Our study introduces a new machine learning algorithm for estimating 3D cumulative radial profiles of total and gas mass in galaxy clusters from thermal Sunyaev-Zel'dovich (SZ) effect maps. We generate mock images from 2522 simulated clusters, employing an autoencoder and random forest in our approach. Notably, our model makes no prior assumptions

    The European Low Frequency Survey. Observing the radio sky to understand the beginning of the Universe
    In this paper we present the European Low Frequency Survey (ELFS), a project that will enable the detection of primordial B-mode polarization by measuring the Galactic and extra-Galactic foregrounds in the 5- 120 GHz frequency window. Indeed, the main difficulty in measuring the Bmode polarization comes not just from its sheer faintness, but from
