NASA Team Finds Noxious Ice Cloud on Saturn's Moon Titan Researchers with NASA's Cassini mission found evidence of a toxic hybrid ice in a wispy cloud high above the south pole of Saturn's largest moon, Titan. The finding is a new demonstration of the complex chemistry occurring in Titan's atmosphere-in this case, cloud formation in the giant moon's stratosphere-and part of a collection of processes that ultimately helps deliver a smorgasbord of organic molecules to Titan's surface. Inv...

ESO's fleet of telescopes in Chile have detected the first visible counterpart to a gravitational wave source. These historic observations suggest that this unique object is the result of the merger of two neutron stars. The cataclysmic aftermaths of this kind of merger - long-predicted events called kilonovae - disperse heavy elements such as gold and platinum throughout the Universe. This discovery, published in several papers in the journal Nature and elsewhere, also provides the strongest ev...

For the first time, NASA scientists have detected light tied to a gravitational-wave event, thanks to two merging neutron stars in the galaxy NGC 4993, located about 130 million light-years from Earth in the constellation Hydra. Shortly after 8:41 a.m. EDT on Aug. 17, NASA's Fermi Gamma-ray Space Telescope picked up a pulse of high-energy light from a powerful explosion, which was immediately reported to astronomers around the globe as a short gamma-ray burst. The scientists at the National S...

The first Copernicus mission dedicated to monitoring our atmosphere, Sentinel-5P, has been launched from the Plesetsk Cosmodrome in northern Russia. The 820 kg satellite was carried into orbit on a Rockot launcher at 09:27 GMT (11:27 CEST) today. The first stage separated 2 min 16 sec after liftoff, followed by the fairing and second stage at 3 min 3 sec and 5 min 19 sec, respectively. The upper stage then fired twice, delivering Sentinel-5P to its final orbit 79 min after liftoff. ...

The first full-scale model of the rocket motor that will propel Ariane 6 and Vega-C into orbit has been cast and filled with inert propellant for testing at Europe's Spaceport in French Guiana. The P120C is the largest solid-propellant rocket motor ever built in one segment. Each P120C will hold over 140 tonnes of propellant in a carbon fibre casing almost 11.5 m long and about 3.4 m in diameter. It is derived from Vega's current first stage motor, the P80, which holds 88 tonnes of propell...

There's no map showing all the billions of exoplanets hiding in our galaxy -- they're so distant and faint compared to their stars, it's hard to find them. Now, astronomers hunting for new worlds have established a possible signpost for giant exoplanets. A new study finds that giant exoplanets that orbit far from their stars are more likely to be found around young stars that have a disk of dust and debris than those without disks. The study, published in The Astronomical Journal, focused on ...

Astronomers have identified a bumper crop of dual supermassive black holes in the centers of galaxies. This discovery could help astronomers better understand how giant black holes grow and how they may produce the strongest gravitational wave signals in the Universe. The new evidence reveals five pairs of supermassive black holes, each containing millions of times the mass of the Sun. These black hole couples formed when two galaxies collided and merged with each other, forcing their superma...

    Multiwavelength Spectral Energy Distribution
    * I have a Master Degree in Physics from the University of Milano (Italy; February 2001).
    * I obtained my PhD in Astrophysics from the S.I.S.S.A. (Trieste, Italy) in October 2006. 
    * In November 2006, I started a 2-years research fellowship in ESA, ESAC center (Madrid, Spain).
    * Immediately after, I was awarded a 3-years post-doc position (“Juan de la Cierva” Spanish fellowship) in IFCA - Universidad  de Cantabria/CSIC (Santander, Spain; December 2008). 
    * In February 2013, I started a 2-years Marie-Curie fellowship (AstroFIt project) at the Brera Observatory (OABrera; Milano, Italy).
    * At present, I am a Postdoctoral Research Fellow (“Assegnista di Ricerca”) at the OABrera.
    My research is related with several topics on Active Galactic Nuclei (AGN). AGN are among the most powerful phenomena in the Universe, and the energy produced by the growth of the black hole can far exceed the binding energy of the entire host galaxy, with profound effect on its evolution. AGN give also observational access to the otherwise elusive supermassive black holes, allowing us to probe among the most extreme physical environments in the Universe. 
    During my career I tackled different AGN-related issues: 
    * the physics at the basis of their emission, through the study of different accretion states; 
    * issues connected with the jet production and composition; 
    * the problem of obscuration due to gas and dust near the central engine; 
    * the AGN interplay with the environment, with particular attention to the circumnuclear star-formation, and the consequence in terms of structure formation and galaxy evolution. 
    My work includes both statistical studies of suitably selected samples, and detailed analyses of the properties of individual objects. 
    * My expertise is mainly related with the high-energy emission of AGN, from extremely X-ray faint objects to the nearby and X-ray brightest sources:
        * I developed considerable expertise in the treatment of many subtleties in X-ray spectra (from the satellites XMM-Newton, Suzaku, Chandra, Swift, BeppoSAX, NuSTAR);
        * I have been Principal Investigator of several accepted proposals for new X-ray observations.
    * I accumulated plenty of experience in combining and analysing data from different bandpasses. 
    * I published 31 papers with referee (nine as leading author) and 3 refereed proceedings; my work has been presented in 24 international conferences. Three more papers are submitted or in preparation (one as first author); h-index = 12. 
    * I act as referee for international astronomical scientific journals (ApJ, MNRAS, A&A). 
    * I served as a panelist for the XMM-Newton Peer Review (2010, 2011).
    * I am scientific supporter for the planning of the European X-ray missions Athena and XIPE.
    * I have been involved in several research projects funded by the Spanish Ministry, the Italian Ministry, the Italian Istituto Nazionale di Astrofisica (INAF), and the Italian Space Agency (ASI).
    * I always contributed to the duties of teaching (mainly in relation to Master students and PhD students), participating also to the activities of outreach.
    Throughout these years I have been working within different international partnerships, and I have demonstrated to be able to carry out independent research, while collaborating at the same time with the groups which I became part of.
