Il teatro di Carlo Cecchi tra Piarandello e Molière

La tesi tratta della carriera teatrale dell'attore-regista italiano Carlo Cecchi, dagli esordi fino ad oggi, ripercorrendo le esperienze più importanti per la sua formazione professionale anche attraverso l'analisi dei suoi spettacoli. L'elaborato presenta, inoltre, due capitoli dedicati al rapporto del regista con autori come Pirandello e Molière e una particolare attenzione verso l'ultimo allestimento del regista, tratto dalla commedia "Tartufo" del commediografo francese, andato in scena in Prima Nazionale il 14 febbraio 2007 presso il tatro Mercadante di Napoli. In appendice sono allegate due interviste, da me realizzate, allo stesso Cecchi sul suo percorso artistico e immagini, fotografie e bozzetti di scena inerenti ad alcuni spettacoli trattati

Stellar Populations, Bars and Secular Evolution in Late-Type Galaxies

We have done a robust statistical analysis of UBV color profiles of 257 Sbc barred and unbarred galaxies. We found that there is an excess of barred galaxies among the objects with null or positive (bluish inward) color gradients, which seems to indicate that bars act as a mechanism of homogenization of the stellar population along galaxies. Moreover, the relationship found between total and bulge colors shows that, in the process of homogenization, the stellar population of bulges are getting bluer, whereas the total color of galaxies remains the same. These characteristics are expected in a secular evolutionary scenario, and seem incompatible with both the monolithic and the hierarchical scenarios for spiral galaxy formation.Comment: 2 pages, 1 table, no figures.

IC 5181: An S0 Galaxy with Ionized Gas on Polar Orbits

The nearby S0 galaxy IC 5181 is studied to address the origin of the ionized gas component that orbits the galaxy on polar orbit. We perform detailed photometric and spectroscopic observations measuring the surface brightness distribution of the stars (I-band), ionized gas of IC 5181 (H-alpha narrow band), the ionized-gas and stellar kinematics along both the major and minor axis, and the corresponding line strengths of the Lick indices. We conclude that the galaxy hosts a geometrically and kinematically decoupled component of ionized gas. It is elongated along the galaxy minor axis and in orthogonal rotation with respect to the galaxy disk. The result is suggesting that the gas component is not related to the stars having an external origin. The gas was accreted by IC 5181 on polar orbits from the surrounding environment.Comment: 4 pages, 5 figures, To appear in ASP Conf. Ser., Multi-Spin Galaxies, E. Iodice and E. M. Corsini (eds.

Pojava mlađi pjevčine pučinke Luvarus imperialis (Actinopterygii: Perciformes: Luvaridae) u Sicilijskom tjesnacu

Two juveniles Luvarus imperialis, astrodermella stage, 97.4 mm and 90.6 mm in total length, were recorded on September 2016 and August 2017 respectively, the first caught by a bottom trawler off the south-eastern coast of Sicily, Strait of Sicily, Italy, the second found stranded on the beach in the nearby region. Biometrics data of this uncommon species are given and the occurrence of juvenile stages in the Mediterranean area is briefly discussed.Dva primjerka mlađi Luvarus imperialis, (stadij astrodermella) ukupnih dužina 97,4 mm i 90,6 mm, zabilježena su u rujnu 2016., odnosno kolovozu 2017. godine. Prvi primjerak je ulovljen koćom na jugoistočnoj obali Sicilije, Sicilijski tjesnac, Italija. Drugi primjerak je pronađen na plaži u obližnjoj regiji. U ovom radu, autori navode biometrijske podatke ove neobične vrste i ukratko se raspravlja o pojavi mlađih u mediteranskom području

A catalogue of nuclear stellar velocity dispersions of nearby galaxies from \u2009H\u3b1 STIS spectra to constrain supermassive black hole masses

We present new measurements for the nuclear stellar velocity dispersion \u3c3* within sub-arcsecond apertures for 28 nearby galaxies. Our data consist of Space Telescope Imaging Spectrograph (STIS) long-slit spectra obtained with the G750M grating centred on the H\u3b1 spectral range. We fit the spectra using a library of single stellar population models and Gaussian emission lines, while constraining in most cases the stellar-population content from an initial fit to G430L STIS spectra. We illustrate how these \u3c3* measurements can be useful for constraining the mass M\u2022 of supermassive black holes (SBHs) by concentrating on the cases of the lenticular galaxies NGC 4435 and NGC 4459. These are characterized by similar ground-based half-light radii stellar velocity dispersion \u3c3e values but remarkably different M\u2022 as obtained from modelling their central ionized-gas kinematics, where NGC 4435 appears to host a significantly undermassive SBH compared to what is expected from the M\u2022 - \u3c3e relation. For both galaxies, we build Jeans axisymmetric dynamical models to match the ground-based stellar kinematics obtained with Spectrographic Areal Unit for Research on Optical Nebulae integral-field spectrograph, including an SBH with M\u2022 value as predicted by the M\u2022 - \u3c3e relation and using high-resolution HST images taken with the Advanced Camera for Surveys to construct the stellar-mass model. By mimicking the HST observing conditions we use such reference models to make a prediction for the nuclear \u3c3* value. Whereas this was found to agree with our nuclear \u3c3* measurement for NGC 4459, for NGC 4435 the observed \u3c3* is remarkably smaller than the predicted one, which further suggests that this galaxy could host an undermassive SBH

Tres nuevas especies de peces exóticos registrados en el área marina de la isla de Rodas (Mar Egeo sud oriental, Grecia)

Three exotic fish, Iniistius pavo (Labridae) and Lagocephalus sceleratus (Tetraodontidae), Lessepsian immigrants, and Seriola fasciata (Carangidae) of Atlantic origin, were recorded in the marine area of Rhodes Island (SE Aegean Sea, Greece). The first species is a new record for the Mediterranean Sea, the second is new for Greek waters, while the occurrence of the third is registered for the first time in the eastern Mediterranean Sea.Tres peces exóticos, Iniistius pavo (Labridae), Lagocephalus sceleratus (Tetraodontidae), inmigrantes lessepsianos, y Seriola fasciata (Carangidae), especie del Atlántico, se registraron en el área marina de la isla de Rodas (mar Egeo sudoriental, Grecia). La primera especie es nueva para el Mediterráneo, la segunda es nueva para aguas griegas, y la tercera es registrada por la primera vez en el Mediterráneo oriental.

Synchiropus sechellensis (Actinopterygii: Perciformes: Callionymidae), nova strana vrsta u Egejskom moru i grčkim vodama

Synchiropus sechellensis (Regan, 1908) was discovered in Kastellorizo Isl. (Levantine Sea, Greece) in September 2014, few months after its first record in Antalya Gulf, Turkey. Later, in February 2016, the species was recorded for the first time in the Aegean Sea, in Rhodes Island. The short time interval between the findings indicates a possible establishment in the area and a dynamic spread of the species northwards in the Eastern Mediterranean.Synchiropus sechellensis (Regan, 1908) je vrsta otkrivena kod otoka Kastellorizo u Levantskom moru (Grčka) u rujnu 2014., nekoliko mjeseci nakon što je po prvi put zabilježena u Antalijskom zaljevu u Turskoj. Ova vrsta je po prvi put zabilježena u Egejskom moru kod otoka Rodosa kasnije u veljači 2016. Kratak vremenski period između ova dva nalaza ukazuje na mogućnost nastanjivanja na ovom području i dinamično širenje vrste sjevernije u istočnom Sredozemlju
