Titolo: Supernova remnants in radio: a multiple approach
Speaker: Adriano Ingallinera, INAF – Osservatorio Astrofisico di Catania
Abstract: Supernova remnants (SNRs) are one of the most prominent sources in the Galactic plane. Emitting throughout the electromagnetic spectrum, they have been a unique laboratory for plasma physics. The radio band is particularly suitable for studying these objects, with more than 95% of all known Galactic SNRs detected at centimetre wavelengths. Here I present a few cases in which we used radio data to characterize SNRs, following different approaches. In the first work, we exploited the unprecedented sensitivity of MeerKAT, the SKA-MID precursor, to achieve a spectral characterization of the radio emission of a sample of 29, poorly studied, SNRs in the southern hemisphere. Results, implications and future work will be summarized. The interferometry has some limitations when observations of objects more extended than a few arcminutes are carried out at frequencies above 10 GHz. In these cases, single-dish telescopes are of great help. In an ongoing work, we are studying the SNR KES 73, using observations we made with the Sardinia Radio Telescope between 7 and 24 GHz. A spatial variation of the spectral index is under investigation. KES 73 is located in a very complex region and it is possibly interacting with some nearby sources. A multiwavelength characterization of the environment and the modeling of its non-thermal emission will be presented. Finally I will discuss the new SKA science book, a collection of science cases for SKA of which I am in charge of coordinating the chapter on SNRs. The book is aimed at giving the community a comprehensive view of the impact of the upcoming SKA observatory.

Titolo: Tirocini e tecnologie emergenti: lune nel metaverso e stelle in realtà aumentata
Abstract:
Dal 2020, l’Osservatorio Astronomico di Palermo (OAPA) promuove tirocini accademici rivolti a studenti e studentesse delle lauree triennali e magistrali in Fisica e Ingegneria, offrendo l’opportunità, attualmente unica in INAF, di approfondire la comunicazione e la didattica dell’astronomia attraverso l’uso di tecnologie innovative come la realtà aumentata (AR) e la realtà virtuale (VR). Durante l’incontro verranno presentati i progetti sviluppati dalle tirocinanti: un tour immersivo nel metaverso dedicato all’esplorazione delle lune del sistema solare e un’esperienza in realtà aumentata che racconta, in modo visivo e interattivo, il ciclo di vita delle stelle. Ci sarà l’opportunità di interagire con i progetti utilizzando visori VR e tablet, per un viaggio nell’universo che combina scienza, tecnologia, ricerca e curiosità.

Titolo: “Retrieving the Atmospheres of Distant Worlds: Insights from High-Resolution Spectroscopy”
Abstract: “High-resolution (HR) transmission spectroscopy has demonstrated exceptional effectiveness in detecting multiple molecular species in the atmospheres of exoplanets. At HR, molecular absorption bands are resolved into thousands of individual spectral lines, allowing for unambiguous identification of species through line matching (e.g., via cross-correlation) with planetary model templates, even when most individual lines are buried within photon noise. The next frontier is to connect the detection of molecular species to the underlying chemical and physical properties of exoplanetary atmospheres. We discuss the prospects of this technique in the context of upcoming facilities, such as the Extremely Large Telescope (ELT), highlighting its potential to revolutionize our understanding of exoplanet atmospheres.”
