Architetture perdute/Architetture ricostruite. Ricostruzioni virtuali attraverso la fotografia d’epoca: un caso studio
2013
I grandi eventi bellici, le intemperie e l'incuria dell'uomo hanno condotto alla rapida rovina di buona parte del patrimonio culturale; il presente contributo affronta il tema della documentazione del patrimonio culturale proponendo una metodologia di ricostruzione congetturale basata sull'uso di fonti iconografiche e su procedure di restituzione prospettica da fotografie d'epoca. Oggetto dello studio è il Castellammare di Palermo, demolito nel 1922 per volontà della stessa amministrazione comunale.
Stellar populations of galaxies in the ALHAMBRA survey up toz ∼ 1
2018
Aims. We aim at constraining the stellar population properties of quiescent galaxies. These properties reveal how these galaxies evolved and assembled since z similar to 1 up to the present time. Methods. Combining the ALHAMBRA multi-filter photo-spectra with the fitting code for spectral energy distribution MUFFIT (MUlti-Filter FITting), we built a complete catalogue of quiescent galaxies via the dust-corrected stellar mass vs. colour diagram. This catalogue includes stellar population properties, such as age, metallicity, extinction, stellar mass, and photometric redshift, retrieved from the analysis of composited populations based on two independent sets of simple stellar population (SSP…
Los Tellos de Meneses by Lope de Vega in the Shaping of the Ideal of the Honourable Peasant
2011
En la primera parte del trabajo se destaca la popularidad de la que gozó la leyenda genealógica sobre la familia de los Tellos de Meneses a través de la recopilación de noticias de representación de obras que se dedicaron a este tema. El artículo se centra después en la bilogía dramática que Lope escribió sobre los orígenes de esta familia: Los Tellos de Meneses y Valor, fortuna y lealtad (segunda parte de Los Tellos de Meneses). Se analizan dos aspectos fundamentalmente: por un lado, el tratamiento que el autor hizo de las fuentes, quizá en un afán por favorecer la imagen de la familia; por otro lado, se analiza el lugar que ocupan estas dos obras de exaltación genealógica en la configurac…
Solar neutrino physics with Borexino
2018
We present the most recent solar neutrino results from the Borexino experiment at the Gran Sasso underground laboratory. In particular, refined measurements of all neutrinos produced in the {\it pp} fusion chain have been made. It is the first time that the same detector measures the entire range of solar neutrinos at once. These new data weakly favor a high-metallicity Sun. Prospects for measuring CNO solar neutrinos are also discussed.
Sub-milliarcsecond imaging of 3C111
2020
Flares in radio-loud active galactic nuclei (AGNs) are thought to be associated with the injection of fresh plasma into the compact jet base. Such flares are usually strongest and appear earlier at shorter radio wavelengths. Hence, very long baseline interferometry (VLBI) at millimeter (mm)-wavelengths is the best-suited technique for studying the earliest structural changes of compact jets associated with emission flares. Aims. We study the morphological changes of the parsec-scale jet in the nearby (z=0.049) gamma-ray bright radio galaxy 3C 111 following a flare that developed into a major radio outburst in 2007. We analyse three successive observations of 3C 111 at 86 GHz with the Global…
MOJAVE. VI. Kinematic analysis of blazar jets
2012
We discuss the jet kinematics of a complete flux-density-limited sample of 135 radio-loud active galactic nuclei (AGNs) resulting from a 13 year program to investigate the structure and evolution of parsec-scale jet phenomena. Our analysis is based on new 2cm Very Long Baseline Array (VLBA) images obtained between 2002 and 2007, but includes our previously published observations made at the same wavelength, and is supplemented by VLBA archive data. In all, we have used 2424 images spanning the years 1994-2007 to study and determine the motions of 526 separate jet features in 127 jets.

GES: pre-main-sequence clusters [Fe/H]
2017
The radial metallicity distribution in the Galactic thin disc represents a crucial constraint for modelling disc formation and evolution. Open clusters allow us to derive both the radial metallicity distribution and its evolution over time. In this paper we perform the first investigation of the present-day radial metallicity distribution based on [Fe/H] determinations in late type members of pre-main-sequence clusters. Because of their youth, these clusters are therefore essential for tracing the current inter-stellar medium metallicity. We used the products of the Gaia-ESO Survey analysis of 12 young regions (age<100Myr), covering Galactocentric distances from 6.67 to 8.70kpc. For the fir…
Gaia-ESO Survey. Parameters for cluster members
2016
The nature of the metallicity gradient inside the solar circle (R_GC_<8kpc) is poorly understood, but studies of Cepheids and a small sample of open clusters suggest that it steepens in the inner disk. We investigate the metallicity gradient of the inner disk using a sample of inner disk open clusters that is three times larger than has previously been studied in the literature to better characterize the gradient in this part of the disk. We used the Gaia-ESO Survey (GES) [Fe/H] values and stellar parameters for stars in 12 open clusters in the inner disk from GES-UVES data. Cluster mean [Fe/H] values were determined based on a membership analysis for each cluster. Where necessary, distance…
