This is a paper led by Kostas from the ASSESS team where we investigated the mass-loss in LMC/s RSGs. Interestingly this made its way to the astrobites site. Establishing a mass-loss rate relation for red supergiants in the Large Magellanic Cloud K. Antoniadis, A.Z. Bonanos, S. de Wit, E. Zapartas, …
The deadline for the 2024 iteration of the Summer School for Astrostatistics in Crete is approaching fast. We are excited to host this event, which actually starts to settle as an annual event. And why not since it seems there is a huge need in practical training in statistics and …
Paper II of the XShootU collaboration is finally accepted at A&A! That is a cornerstone paper for the collaboration since it presents the analysis of the observations and provides the final scientific products with which the whole collaboration (and everybody else) can work with. X-Shooting ULLYSES: Massive Stars at low …
I have been using Python almost 15 years now! Starting from 2, over 3 and the many advances in the meantime (e.g. astropy!). So, this semester (Sprint 2024) i will be teaching the course “Introduction to Python for Physicists” (F-254) at the University of Crete. This will be an intro …
A paper that collectively presents the results from our intensive observing campaign in the ASSESS project, focusing on the southern galaxies (a forthcoming paper will deal with the northern ones). Investigating episodic mass loss in evolved massive stars: I. Spectroscopy of dusty massive stars in ten southern galaxies A.Z. Bonanos, …
With increasing distance fainter stars, and therefore those of lower luminosity, older populations, become less observable. This means that with increasing distance we actually probe different parts of a Color-Magnitude diagram (CMD), which mainly consists of the brightest and more evolved massive stars. This is best shown in this figure …
This is the paper that describes the ASSESS project for which I have been working since 2018 ! Introducing the ASSESS project: Episodic Mass Loss in Evolved Massive Stars – Key to Understanding the Explosive Early Universe A.Z. Bonanos, G. Maravelias, M. Yang, F. Tramper, S. de Wit, E. Zapartas, …
Between 26-28 of July (2023), I managed to participate in-person the 16th Hellenic Astronomical Conference, held in Athens. I personally contributed with one talk and one poster (long gone the days that I would submit two talks!), which was part of the ASSESS group’s contribution with another two talks, and …
Although I thought at the beginning that this would be a quick paper, it took considerable time to complete! Thanks a lot to Stephan that did significant work with figures I was able to focus on the text and the discussion. This is the first work to reveal B[e] Supergiants …
It was back in 2020 during the pandemic that the first call for the XShootU collaboration was sent. I had really little idea of what would follow, but I fount it definitely motivating to participate. Therefore I volunteer to help with the data reduction. After 2.5 years we are getting …
