Publication Open Access JWST MIRI and NIRCam observations of NGC 891 and its circumgalactic medium(2024)We present new JWST observations of the nearby, prototypical edge-on, spiral galaxy NGC 891. The northern half of the disk was observed with NIRCam in its F150W and F277W filters. Absorption is clearly visible in the mid-plane of the F150W image, along with vertical dusty plumes that closely resemble the ones seen in the optical. A ∼10 × 3 kpc2 area of the lower circumgalactic medium (CGM) was mapped with MIRI F770W at 12 pc scales. Thanks to the sensitivity and resolution of JWST, we detect dust emission out to ∼4 kpc from the disk, in the form of filaments, arcs, and super-bubbles. Some of these filaments can be traced back to regions with recent star formation activity, suggesting that feedback-driven galactic winds play an important role in regulating baryonic cycling. The presence of dust at these altitudes raises questions about the transport mechanisms at play and suggests that small dust grains are able to survive for several tens of million years after having been ejected by galactic winds in the disk-halo interface. We lay out several scenarios that could explain this emission: dust grains may be shielded in the outer layers of cool dense clouds expelled from the galaxy disk, and/or the emission comes from the mixing layers around these cool clumps where material from the hot gas is able to cool down and mix with these cool cloudlets. This first set of data and upcoming spectroscopy will be very helpful to understand the survival of dust grains in energetic environments, and their contribution to recycling baryonic material in the mid-plane of galaxies....Scopus© Citations 6 2 3 - Some of the metrics are blocked by yourconsent settings
Publication Open Access L’approccio STEM per la scuola dell’infanzia: report di un’esperienza didattica per un target di 4-5 anni.(O.A. Padova, 2025)Number: 342Favorire un approccio STEM è una delle priorità delle politiche europee degli ultimi anni, dovendo far fronte alla carenza di qualifiche e competenze in queste discipline. Questo approccio è fortemente incentivato anche dalle Linee Guida del Ministero dell’Istruzione e del Merito, adottate con il D.M. n. 184 del 15.9.2023, rivolte a tutti gli Istituti scolastici di ogni ordine e grado, al fine di introdurre nel PTOF (Piano Triennale dell’Offerta Formativa) azioni atte a potenziare le competenze matematico-scientifico-tecnologico cercando di appassionare alle materie scientifiche gli studenti fin dalla Scuola dell’Infanzia. Nell’ambito della realizzazione di attività di disseminazione e educative che consentano di sviluppare la passione verso le discipline scientifiche, risulta necessario progettare esperienze e laboratori con contenuti specifici adatti per un target d'età prescolare come quello della scuola d’infanzia. Il presente report riporta la progettazione e realizzazione di un laboratorio didattico con più attività, realizzato in occasione della visita all’INAF-Osservatorio di Padova di una scuola d’infanzia di Padova, con particolare riferimento alle attività progettate per il gruppo di bambine e bambini di età 4-5 anni.13 10 - Some of the metrics are blocked by yourconsent settings
Publication Open Access Data Release 3: the Solar System survey(2023)The third data release by the Gaia mission of the European Space (DR3) is the first release to provide the community with a large sample of observations for more than 150 thousand Solar System objects, including asteroids and natural planetary satellites. The release contains astrometry (over 23 million epochs) and photometry, along with average reflectance spectra of 60518 asteroids and osculating elements. We present an overview of the procedures that have been implemented over several years of development and tests to process Solar System data at the level of accuracy that Gaia can reach. We illustrate the data properties and potential with some practical examples. In order to allow the users of DR3 to best exploit the data, we explain the assumptions and approaches followed in the implementation of the data processing pipeline for Solar System processing, and their effects in terms of data filtering, optimisation, and performances. We then test the data quality by analysing post-fit residuals to adjusted orbits, the capacity of detecting subtle dynamical effects (wobbling due to satellites or shape and Yarkovsky acceleration), and to reproduce known properties of asteroid photometry (phase curves and rotational light curves). The DR3 astrometric accuracy is a clear improvement over the data published in DR2, which concerned a very limited sample of asteroids. The performance of the data reduction is met, and is illustrated by the capacity of detecting milliarcsecond-level wobbling of the asteroid photocentre that is due to satellite or shape effects and contributes to Yarkovsky effect measurements. The third data release can in terms of data completeness and accuracy be considered the first full-scale realisation of the Solar System survey by Gaia.Scopus© Citations 40 11 6 - Some of the metrics are blocked by yourconsent settings

Publication Exo-MerCat v2.0.0: Updates and open-source release of the Exoplanet Merged Catalog software(2025-04)Exoplanet research is at the forefront of contemporary astronomy recommendations. As more and more exoplanets are discovered and vetted, databases and catalogs are built to collect information. Various resources are available to scientists for this purpose, though every one of them has different scopes and notations. In Alei et al. (2020) we described Exo-MerCat a script that collects information from multiple sources and creates a homogenized table. In this manuscript, we announce the release of the Exo-MerCat v2.0.0 script as an upgraded, tested, documented and open-source software to produce catalogs. The main upgrades on the script concern: (1) the addition of the TESS Input Catalog and the K2 Input Catalog as input sources; (2) the optimization of the main identifier queries; (3) a more complex merging of the entries from the input sources into the final catalog; (4) some quality-of-life improvements such as informative flags, more user-friendly column headers, and log files; (5) the refactoring of the code in modules. We compare the performance of Exo-MerCat v2.0.0 with the previous version and notice a substantial improvement in the completeness of the sample, thanks to the addition of new input sources, and its accuracy, because of the optimization of the script.Scopus© Citations 1 18 6 - Some of the metrics are blocked by yourconsent settings
Publication Open Access The impact of physical processes on the estimation of the ages of asteroid families(2021)One of the methods used to estimate the ages of the asteroid families is based on the interpretation of the distribution of the sizes versus orbital semimajor axes of their members as the result of their post-formation dynamical evolution. The fundamental hypothesis is that the present distribution of the semimajor axes is essentially the product of the Yarkovsky effect. On the other hand, the observable features of the asteroid families can be affected by several physical and dynamical processes. In this paper, we discuss the role of: (1) the initial distribution of the ejection velocities at the time of the primordial break-up event; (2) the possible correlations between the family members ejection direction and the orientation of the rotational axis (which the direction of the Yarkovsky semimajor axis drift depends on); (3) the gravitational reaccumulation of the parent body fragments during the ballistic phase of the formation process; and (4) the collisional re-orientation of the spin axes during the post-formation evolution phase. We show how each of these mechanisms affects the determination of the ages of the asteroid families, and what additional information can be inferred regarding some aspects of the collisional evolution of the rotation axes.16 7Scopus© Citations 4
