Stella Avgousti is joining the ASSESS team, to work on the cross matching of the most recent Gaia data with products of the project. In particular, she will test the predictions of the machine-learning classifier with spectra provided by the Gaia space mission.
Properties of luminous red supergiant stars in the Magellanic Clouds S. de Wit, A.Z. Bonanos, F. Tramper, M. Yang, G. Maravelias, K. Boutsia, N. Britavskiy, and E. Zapartas There is evidence that some red supergiants (RSGs) experience short lived phases of extreme mass loss, producing copious amounts of dust. These …
Gonzalo Munoz-Sanchez traveled to Tenerife (Spain) for a week in September (5-9), to participate in the XV scientific meeting of the Spanish Astronomical Society. There he presented his work from the reduction of GTC multi-object spectroscopic data we have obtained for NCG 6822 and IC 10 galaxies. The poster is …
A few days ago we were notified that our latest proposal to use EMIR, an IR spectrograph at 10.4m GTC, was accepted! We are going to use it to observe in the near-IR a number of Red Supergiants in the NGC 6822 and IC 10 galaxies, for which we have …
For three days in June (20-23, 2022) a – broader – meeting of the VFTS project took place in Heidelberg. Stephan de Wit represented the ASSESS project by contributing with the talk: ” ASSESSing Red Supergiants, in the Local Group … and beyond!”. After a short presentation of the whole …
For the 17th year, Penn State’s Center for Astrostatistics offered its week-long Summer School in statistical methodology for astronomy. The School provides an intensive program in statistical inference covering topics such as principles of probability and inference, regression and model selection, bootstrap resampling, multivariate clustering and classification, Bayesian data analysis, …
Grigoris got an invitation in March to give a talk to the Thüringer Landessternwarte Tautenburg, scheduled for June 21 (the summer solstice 2022). With the title “The ASSESS classifier: a machine-learning tool to uncover populations of evolved massive stars in nearby galaxies” he gave an introduction to the massive stars …
Aimilia Tsopela joined the ASSESS team as a summer student (2022), to gain experience with astronomical observations and fitting with DUSTY.
The IAU Symposium 361: “Massive Stars Near and Far” was held in Ballyconnell, Ireland in the week of 8-13 May 2022. That was our first in-person meeting since the start of the pandemic, and the ASSESS team took advantage of the opportunity to travel to Ireland to present our work. …
Stathis Athanasiou joined the ASSESS team recently. He is mainly working on target cross-matching with Hubble Space Telescope images, so that we can retrieve more information for our sources.
