Our PhD student Sara Vitali was recently granted one of the competitive ESO studentships to conduct part of her PhD at ESO. We make her some questions here about what this means. What will you do at ESO? I will do part of my PhD project, collaborating with Dr. Ditte Slumstrup and Dr. Heidi Korhonen. We …

The first academic semester in Chile had just finished in June. It was a very long semester, with so much work, and we really needed a break. The first week of July, however, promised to be everything but a break: The stellar and galactic astronomy group led by Prof Paula Jofre obtained observing time for …
AstroUDP student Thallis Pessi publishes a paper in ApJ. The paper describes the event SN 2011fh, a peculiar transient similar to the ambiguous SN 2009ip. This event became famous for the difficult in telling whether it was a true core-collapse supernova or an energetic eruption in a massive star. In this paper, we use multiple …
J01020100-7122208 is a very interesting star that was believed to be a red giant that was accelerated by the central supermassive black hole of the Milky Way (Sagittarius A*). In this work, this star was revisited using Gaia EDR3 and high-resolution spectra from Mike spectrograph at Las Campanas observatory. Using this data, it was possible …
Today there was a planned activity, the students presented their work to the rest. In person was it not, what a pity but there’s nothing to do, not worth to protest. The reasons for scientific exchanges are a lot. They might start from absorbing each others learning, to end up realising out how much we …
Galaxies are cooking on gas. More specifically, the molecular gas in galaxies is the fuel for star formation, so measuring how much of it was present in the high-redshift universe is an important step for understanding galaxy evolution. In his first first-author paper, our PhD student Manuel Solimano investigated the molecular gas content of four …

The pandemic has forced us to keep social distancing. In astronomy we are lucky to be one of the few disciplines that, in principle, can keep doing science remotely. In fact, the community just went fully online. Almost everyone is working from home, probably wearing comfy clothes and having a routine that perfectly matches each …
One of our first Ph.D. students, Kriti Kamal Gupta, recently got a paper accepted for publication in MNRAS. The paper focuses on understanding the properties of \\\”Thomson-Scattered X-ray Radiation in Obscured Active Galactic Nuclei\\\”. Using the 70-month Swift/BAT catalog, she investigated possible correlations between the fraction of scattered radiation and different physical properties of accreting supermassive …
At the end of the last year, one of our students, Camilo González-Ruilova, published a deep study of an incredible system of two protoplanetary disks with apparent interaction. ALMA observations of ultra-high resolution (around 3 au or 30 mas) revealed a big protoplanetary disk formed by a large cavity and two non-axisymmetric rings, and near …
