Evangelia put a lot of effort in this work, and she nailed it! The goal was to investigate through IR spectroscopy some particular interesting sources identified from our previous work with optical spectroscopy. We successfully found evidence of episodic mass loss in four of them. Investigating episodic mass loss in …
This is a major work with contributions for many many people as we try to understand the behavior of massive stars at low metallicity. And of the key factors is binarity, how does it change when metallicity decreases ? A high fraction of close massive binary stars at low metallicity …
It is more than a month sine the end of the 2025 Summer School of Astrostatistics in Crete. This time was needed to cool down and to complete other urgent tasks (attending another conference, complete the Python course obligations, etc). So it is actually only a few days ago that …
It is early 2010, I have just started my PhD in Astrophysics and I am trying to understand how to do things. Previously I was using mainly spreadsheets (either through Excel or Origin), but now I have to deal with different formats and approaches. Images, strange format that can hold …
This is the complementary work to that of Alceste’s published some time ago, covering the southern galaxies. Now it was Stephan and Gonzalo’s turn to lead this the paper for the northern galaxies, observed with the 10.4 m GTC. We managed to classify 122 additional sources, increasing the number of …
Finally…after some years from the initial paper on the method I managed to put everything together to publish the second part of the machine-learning classifier for massive stars in nearby galaxies. This work is actually the application of the classifier to the whole sample of 26 galaxies and about 1.1 …
Kostas has been actively working on determining the mass loss rate for Red Supergiants across various metallicities. We had plenty of these sources for NGC 6822 so it was natural to include them in a straight comparison with SMC, LMC and the Milky Way. However, each of these galaxies have …
Soon after the first paper of the BLOeM collaboration (describing the survey) another two papers followed on the multiplicity properties of specific populations. In one of them, led by Julia Bodensteiner and Tomer Shenra, we looked into the multiplicity properties of the OBe population in the SMC. This is of …
This is it ! Its on! 🚀 💫 The 5th iteration of our Summer School for Astrostatistics in Crete will be hosted at the University of Crete, in the week 16-20 of June. It has been an amazing journey so far, and as each year builds upon the previous we …
Last year, In 2024 I took over the responsibility to teach a university course for the first time. Was it overwhelming? Without a doubt! Sure, I have been using python for almost 15 years, but condensing all that experience into a structured course … was definitely challenging. Fortunately, i had …
