Figure from the paper showing detected streams in the Milky Way in Cartesian coordinates, where streams are shown as highlighted volumes. The Sun is at X=Y=Z 0 pc (the red cross): so these streams are all around us!
What happens when a star cluster disperses? Well, it forms a stream of stars - and those streams are all around us!
In a new paper by Sebastian Ratzenböck at the CfA / @univie.ac.at, we looked into streams near to the Sun, and found that the Milky Way's disk is *full* of streams! 🔭☄️🧪 #galactic
Globular star cluster Omega Centauri packs about 10 million stars much older than the Sun into a volume some 150 light-years in diameter. Also known as NGC 5139, at a distance of 15,000 light-years it's the largest and brightest of 200 or so known globular clusters that roam the halo of our Milky Way galaxy. Though most star clusters consist of stars with the same age and composition, the enigmatic Omega Cen exhibits the presence of different stellar populations with a spread of ages and chemical abundances. In fact, Omega Cen may be the remnant core of a small galaxy merging with the Milky Way. With a yellowish hue, Omega Centauri's red giant stars are easy to pick out in this sharp telescopic view. A two-decade-long exploration of the dense star cluster with the Hubble Space Telescope has revealed evidence for a massive black hole near the center of Omega Centauri.

Grande Francesca! Congrats!
Our sister institute at Durham, the Centre for Extragalactic Astronomy, are advertising for a five year lectureship position 🔭☄️
Advertisement is here, have a look and come join us in pretty Durham: durham.taleo.net/careersectio...

I plan to improve it in the future.
Meanwhile, here is some very basic documentation (still a work in progress).

The tool is quite basic and rough, with some fine-tuning, but it's very straightforward to use. The resulting dashboard is clear and simple to interpret. I'm really happy with how I used AI to help with the development 😄
It compares PDF and Word documents across different folders and subfolders in the Moodle assignment submission structure, and tells me who copied from whom—and what percentage was copied.
I got extremely frustrated with students copying Physics lab reports. Since I’m not good at adapting existing tools, I developed my own plagiarism detection tool.
Today is the International Day of Women and Girls in Science— a perfect opportunity to promote the Special Session we are organizing at the upcoming European Astronomical Society conference: eas.unige.ch/EAS_meeting/.... Stay tuned!

Just got my Italian "#Habilitation" (#ASN) as an Associate & Full Professor :)
