José Schiappacasse

Stellar populations from the tail of the world pdf

In this talk, I will briefly introduce myself and my role at the observatory. I will also give an overview of my journey in astronomy — from my early research to the current projects I am involved in — highlighting, in particular, my work on the HRMOS project.

 

Rodolfo Dernini

Super Resolution for Radio Telescopes pdf

In this talk, I will share insights from my research at the Arcetri Observatory, where I am focused on enhancing the angular resolving power of radio telescopes. I will introduce the concept of super-resolution, which makes it possible to bypass the diffraction limit by employing variable transmittance filters known as Toraldo pupils.

Maite Echeveste

From the Southwest to the Northeast: tracing a path through exotic binaries pdf

In this talk, I will take you on a journey through my research path — starting with spiders, ultra-compact binaries, and blue stragglers, and leading up to my current work in the StarDance project, where we explore the role of interacting binaries in shaping non-canonical stellar populations.

 

Mélanie Armante

From SNR to protoplanetary disk: a journey into star formation

In this presentation I will briefly introduce my home town Saint Germain en Laye, home of French kings, and then my science journey from Supernova remnant to the understanding of massive star formation and of planet formation.

Lucia Armillotta

Studying the interstellar and circumgalactic media with magnetohydrodynamical simulations

In this talk, I will provide an overview of my research in the area of theoretical and computational astrophysics studying galaxy evolution, with a particular focus on the gas cycle in and around galaxies. I will also present some colorful visualizations from my magnetohydrodynamic simulations to illustrate these processes.

 

Maria Vittoria Zanchettin

From Single to Dual AGN: A Multiphase Perspective pdf

In this informal talk, I will briefly introduce myself and provide an overview of my past and ongoing research. My work primarily focuses on Active Galactic Nuclei from an observational perspective, beginning with AGN feedback in nearby galaxies and extending to dual AGN at higher redshifts.

Aleksandra Avdeeva

Permian, Big Data, and a Cat pdf

In this talk, I will share how my passion for astronomy led me from the Ural Mountains to Arcetri. I have worked with large astronomical survey data — from the search for brown dwarfs to estimating interstellar extinction — and I am now part of the StarDance project here. Along the way, I am accompanied by big data, curiosity, and my scientist-cat.

Francesco Maio

Planet Hunter's Playground: Where Young Planets Hide pdf

Join me on my journey as a planet hunter, from pursuing my passion for exoplanets to traveling to Paranal to observe with VLT/ERIS. I will share the challenges of searching for protoplanets hidden in dusty disks and reveal the excitement of discovering the first promising candidates.

28/01/2025

Elisabetta Reggiani

Me & my Blue Stragglers

In this talk I will introduce myself, where I come from, what I studied and - very briefly - the research I have done so far. I will then add something about my current work and my interests.

 

Paolo Picchi

ARIEL: The first space telescope with Aluminum optics pdf

ARIEL is an ESA medium class mission devoted to the study of exoplanets atmospheres. Currently, the program is phase C and will go through the Critical Design Review (CDR) at the end of this year. In this talk, I will provide details on the central role in the program covered by the group here in Arcetri, as the lead team of the ARIEL Telescope Assembly. In particular, I will focus the presentation on the technological research we are doing on aluminum optics and my role as System Manager for the Telescope Assembly.

Vladimiro Noce

Il lancio di PROBA-3: un coronografo gigante nello spazio realizzato attraverso il preciso posizionamento di satelliti ppt

PROBA-3 è una missione ESA il cui scopo è di dimostrare la precisione del volo in formazione di una coppia di satelliti che realizzeranno nello spazio un coronografo lungo 150 metri. Un disco da 1.4 metri agirà da occultatore, generando un'eclisse artificiale, mentre l'altro acquisirà immagini nel visibile della corona solare fino a 1.1 raggi solari per periodi di ore, non ottenibili durante le eclissi naturali.

 

Germano Sacco

Machine Learning for Spectroscopy ppt

In the last few years, we started to study the applications of new algorithms based on Machine Learning to the analysis of spectroscopic data in Astronomy. In this talk, I will give a very short overview of whole project, the results and the plan for the next future.

Giovanna Caprio

SOS Valutazione Qualità della Ricerca (VQR) ppt

L'incontro ha lo scopo di supportare ricercatori e tecnologi, accreditati per la VQR 2020-2024, nel recupero dell'inserimento delle pubblicazioni (tralasciate in precedenza) nel repository istituzionale, al fine di consentire l'avanzamento delle procedure di invio dei prodotti a LoginMIUR, indispensabili per il conferimento indicato nel bando ANVUR. Sono previsti un ripasso degli step delle submissions nel repository, chiarimenti sull'import delle pubblicazioni da ADS e suggerimenti utili ad ottimizzare i tempi di immissione dei prodotti.

Ruggero Stanga (Planetario di Firenze, Osservatorio Polifunzionale del Chianti)

Il Planetario della Fondazione Scienza e Tecnica di Firenze: come lo usiamo?

Il titolo è abbastanza lungo da essere esso stesso un abstract: programmi ed eventi in via Giusti 29 (l'indirizzo del Planetario, per evitare equivoci!)

Tomas Azevedo Silva

The search for chemical disequilibrium in exoplanet atmospheres pdf

When a planet crosses in front of its host star, the atmosphere filters the stellar light, leaving distinct signatures in the observed spectrum. In this 10-minute flash talk, I will show how these transiting events provide invaluable glimpses into the composition, structure, and dynamics of exoplanetary atmospheres, and how I am currently on the hunt for the intriguing effects of chemical disequilibrium.

 

Olga Bayandina

Going South: A Career Path Among the World's Largest Telescopes pdf

As my time at Arcetri comes to an end, I would like to share the path that brought me here and the new roads Arcetri has opened for me. Following my career, we'll go south (geographically, not figuratively!) and take a look behind the scenes of the "world's largest" telescopes I have had the privilege to work for: the Space-VLBI mission RadioAstron, the European VLBI Network, and, finally, my next destination - the Square Kilometer Array. It's a tale of technology, teamwork, and a fair bit of travel - come along for the ride!

Laura Scholz-Díaz

Galaxy stellar populations illuminating dark matter halo evolution pdf

In this informal talk, I will briefly introduce myself and provide an overview of my past and ongoing research regarding the interplay between galaxies and their host dark matter halos from an observational point of view.

 

Pietro Ferraiuolo

Astrobigné: Introducing myself at Arcetri pdf

I will introduce myself, being a new AdR since April this year, telling where do I come from, what I studied, the (little) researches I did before coming here, and then I will explain what I am working on here in OAA and some little "cool" things I did so far.

Niccolò Bucciantini

PWNe with IXPE: GO1 phase for 3C58 pdf

IXPE is the first satellite fully devoted to X-ray polarimetry. In the past 3 years, since it was launched in December 2021, it has measured polarisation in tens of different sources. PWNe were and are among the primary targets of the mission, due to their synchrotron dominated spectrum. Since 2024 IXPE is on GO mode. 3C58 was one of the 2 PWNe selected, and was observed in July-August. I will review briefly the IXPE mission, for those unfamiliar with it, and present the preliminary results for 3C58.

 

Edvige Corbelli

IAU: aims, history, structure and membership pdf

The International Astronomical Union was founded in 1919 by 7 countries and the first General Assembly took place in Rome soon after Italy joined IAU. I will give a brief summary of the actual status of the IAU, describing its structure, aims and approaching deadlines in view also of the next GA which will be held in Rome in 2027.
