Future Astrobigné

 


 

The Astrobigné concept

Astrobigné is a series of short seminars that are held at the Osservatorio, with the goal of interconnecting the community of people working here, spreading new ideas and results, creating and reinforcing synergies between groups and indiduals. As such, Astrobigne's are meant to be accessible to a broad audience, including astronomers and technology staff, from senior researchers to students. Not by chance, the name "bigné" was chosen to designate something delicious, attractive, quick to grasp and easy to "eat".

In practice, the astrobigne talks:

  • must be short (10 minutes plus 5 for open discussion, strict, 6-8 slides at most)
  • must present only 1-2 key points that people can assimilate quickly
  • should be aimed at triggering later discussions, collaboration, and future activities.
  • at this aim, can also present ongoing work with intermediate results
  • can cover a broad range of topics, including astronomy, technology, historic research, public outreach, organization etc...
  • will NEVER present a general overview of the subject and a complete account of the speaker's work
  • are given in English whenever possible (this is not because we don't love Italian, but we all understand that English is our professional language to be used to foster international collaborations. Not to mention that there usually are non-Italians in the audience).

Astrobigne's take place on Tuesdays, every two weeks in the main auditorium of OAArcetri (Aula A). We usually have three bigne'-talks (10+5minutes each), selected by the organizing committee in order to cover as many different areas of interest as possible. Before the talks, at 11:45, we normally meet in Aula A to socialize and eat real bigne's (pastries!). The talks start at noon approximately, but everybody is strongly advised to come by 11:45 so not to miss the... beginning of the talks!

The Astrobigné Organizing Committee is currently composed of Sperello di Serego Alighieri (reference person for the extragalactic group), Fabrizio Massi (for the planets and star formation group, solar physics area), Luca Fini (for the technological area), and Antonella Gasperini (for the library, outreach and history), supported by our director Filippo Mannucci and by the invaluable help of Emanuela Masini with the "real" stuff. If you wish to give a presentation, first contact the relevant reference person and then fill in the doodle!


 

Past Astrobigné

Season 2016-2017


 

Tuesday 6 December 2016 - 11:45 Aula A

Francesco Fontani [OAArcetri]  (Star Formation)

The magnetic field drives the fragmentation of massive star-forming clouds into individual stars
I will present ALMA observations at 0.25'' resolution of a very young massive star-forming clump, IRAS 16061-5048c1, which clearly indicate that the clump fragmentation is dominated by the magnetic field, as suggested by theory.

 

Fabio Rossi [OAArcetri]  (Software)

Introduction to the Jupyter Notebook
It is an application which runs inside your browser, allowing you to create and share documents that contain live code, equations, visualizations and explanatory text, for applications like teaching, data analysis and reporting, experimenting with programming languages, prototyping software.

 

Tuesday 22 November 2016 - 11:45 Aula A

Marco Padovani [OAArcetri]  (Music & Astronomy)

The Resounding Universe
The immensity of the sky and the sparkling stars have inspired mankind from time immemorial and many scientists were music lovers or even musicians themselves: Galileo, Herschel, Einstein... I will highlight the peculiar and intriguing connection between music and astronomy.

 

Simone Esposito [OAArcetri]  (Instrumentation)

Next VLT instruments and adaptive optics
We briefly report about two new AO based VLT instruments planned for the VLT UT4 (the UT equipped with deformable secondary and lasers). Arcetri is technically involved in both and has already being allocated ~60 nights of GTO for one of them. Involving astronomers in the exploitations of such instruments is indeed mandatory and we would like to stimulate interests on these projects.

 


 

Tuesday 8 November 2016 - 11:45 Aula A

Filippo Mannucci [OAArcetri]  (Instrumentation)

What will we do with MAORY/MICADO?
The first light of the E-ELT high-resolution camera MICADO fed by the AO system MAORY is expected in 2024. The MAORY science working group is starting to collect updated science cases to create a document on the science allowed by the new telescope. I will present the properties of the instrument and present the possibility for everyone of contributing to the process.

 

Mikkel Stockman [DARK, Copenhagen]  (Extragalactic)

Counting Holes in the Universe: Statistics of Ly-a voids at z~2-4
Using VLT (UVES) and Keck (HIRES) high resolution quasar spectra (R~50.000) in the range 2≤z≤4, we compare the observational number of Lyman-α voids to expectations from recent hydrodynamical simulations by Graziano Rossi et al. (2014).

 


 

Tuesday 18 October 2016 - 11:45 Aula A

Matilde Mingozzi [OAArcetri]  (Extragalactic)

Investigating the AGN-starburst connection in a nearby Seyfert galaxy
We have analyzed and modelled the CO emission of a nearby Seyfert galaxy, NGC 34, with the aim of understanding the ISM properties in terms of density, temperature and dominant radiation field. NGC 34 represents a galaxy "prototype", therefore our approach can be seen as a pathfinder for future studies.

 

Antonella Gasperini [OAArcetri]  (Outreach)

The "Notti d'Estate" 2016
We present a retrospective look at the Notti d’Estate in Arcetri: an overview and some qualitative and quantitative considerations about the public outreach events of the last summer.

 

Fabrizio Massi [OAArcetri]  (Instrumentation)

Observing with the Sardinia Radio Telescope: a visiting astronomer's account
The Sardinia Radio Telescope has come into operation and an Early Science Programme was run from February 1 to May 31, this year. I spent 3 days observing with the SRT at the end of May in the framework of the programme and this talk will be a brief account of those days from the point of view of a visiting astronomer.

 


 

Tuesday 4 October 2016 - 11:45 Aula A

Giovanni Cresci [OAArcetri]  (Seminars)

ANY GIVEN THURSDAY: a survey on general seminars in Arcetri
We briefly review the results of the survey on the Thursday General Seminars, the plans for the new year, as well as some numbers and statistics on the previous seasons.

 

John Brucato [OAArcetri]  (Solar System)

The Sample Return Mission OSIRIS-REx
OSIRIS-REx was successfully launched into space on 8th September 2016 from Kennedy Space Center. OSIRIS-REx is traveling to Bennu, a carbonaceous asteroid whose regolith may record the earliest history of our Solar System, it will collect and return samples back to Earth seeking answers to the questions that teach us about the history of the Sun and planets and the origin of life on Earth.
