Congratulations to former Carnegie Science Earth and Planets Laboratory Staff Scientist Sara Seager, who is one of two winners of the 2024 Kavli Prize in Astrophysics for her work on discovering and characterizing exoplanets and their atmospheres. In a Q&A with Frank Sesno after the announcement, she said Carnegie Science was one of the only places investing in exoplanet science at the start of her career. https://lnkd.in/emCT5ecW

📃Scientific paper: Stellar Population Astrophysics (SPA) with TNG, Fluorine abundances in seven open clusters Abstract: The age, evolution, and chemical properties of the Galactic disk can be effectively ascertained using open clusters. Within the large program Stellar Populations Astrophysics at the Telescopio Nazionale Galileo, we specifically focused on stars in open clusters, to investigate various astrophysical topics, from the chemical content of very young systems to the abundance patterns of lesser studied intermediate-age and old open clusters. We investigate the astrophysically interesting element fluorine (F), which has an uncertain and intriguing cosmic origin. We also determine the abundance of cerium (Ce), as F abundance is expected to correlate with the s-process elements. High-resolution near-infrared spectra were obtained using the GIANO-B spectrograph. The Python version of Spectroscopy Made Easy (PySME), was used to derive atmospheric parameters and abundances. The stellar parameters were determined using OH, CN, and CO molecular lines along with Fe I lines. This paper presents the first F Galactic radial abundance gradient. Our results are also compared with literature estimates and with Galactic chemical evolution models that have been generated using different F production channels. Our results indicate a constant, solar pattern in the [F/Fe] ratios across clusters of different ages, supporting the latest findings that fluorine levels do not exhibit any secondary behavior for stars with solar or above-solar metallicity. By comparing our sample stars with the p... Continued on ES/IODE ➡️ https://etcse.fr/tPnR ------- If you find this interesting, feel free to follow, comment and share.

The Kavli Institute for Particle Astrophysics and Cosmology recently celebrated its 20th anniversary! After two decades of generating insights into dark matter, black holes, galaxy formation, and the 14-billion-year-long history of the universe, KIPAC scientists are now looking forward to new telescopes, new synergies, and new ways to look at a whole lot of new data. https://ow.ly/Znlq50QE4f5

An ambitious new suite of telescopes at Carnegie’s Las Campanas Observatory will create a spectroscopic map of our Milky Way galaxy and other nearby galaxies, enabling a new understanding of how they form and evolve. “I approach the LVM through the lens of our theoretical understanding of galaxy and star formation—the physical conditions of plasma as it goes through different cosmic cycles,” explained SDSS-V Director Juna Kollmeier, the Founding Director of the Carnegie Theoretical Astrophysics Center and current director of the Canadian Institute for Theoretical Astrophysics. “For decades, we have been doing calculations that zoom-in on these processes, but what was missing was the empirical benchmark. The LVM attempts to provide this reality check: observational targets against which our understanding can be challenged and deepened." https://lnkd.in/gMEeE6nf

New astrophysics model sheds light on additional source of long gamma-ray bursts, New York NY (SPX) Nov 30, 2023 Cutting-edge computer simulations combined with theoretical calculations are helping astronomers better understand the origin of some of the universe's most energetic and mysterious light shows - gamma-ray bursts, or GRBs. The new unified model confirms that some long-lasting GRBs are created in the aftermath of cosmic mergers that spawn an infant black hole surrounded by a giant disk of natal m,

✨🎙📻 Last month, Antoine Alaguero participated to a radio broadcast by Radio Campus Grenoble with the participation of the Observatoire des Sciences de l'Univers de Grenoble to talk about comics and astrophysics. Antoine is currently doing his PhD at the Institut de Planétologie et d'Astrophysique de Grenoble and his is a very active member of the Stellar-MADE project. Together with The Ink Link and Séverine Alvain, we developed a series of comics about exoplanets and multiple stellar systems. Among other things, the participants discussed about: - How do we collect light in the largest telescopes in the world? - How and why should scientific knowledge be narrated and illustrated? - What does comics bring to science? The 30min-long broadcast is in French and can be found here: https://lnkd.in/ezaTuwVc Our comics can be found here instead: https://lnkd.in/d-4GcMYX --------------- European Research Council (ERC) #outreach #radio #astrophysics #astronomy #comics #science

Did you know that there is gravity in space? That is one common misconception (among others) that Julia Kregenow, teaching professor of astronomy and astrophysics, is here to debunk. Today is International Astronomy Day, so what better way to celebrate than to share some misconceptions about astronomy and why they aren't true?

We now have the largest 3-D map of our cosmos ever created, thanks to a powerful instrument mounted atop a telescope in Arizona with a robotic array of 5,000 fiber-optic “eyes” that look into the night sky. Over the last five years, the Dark Energy Spectroscopic Instrument—known in science circles as DESI—has measured the spectra of more than 30 million galaxies and 3 million quasars to determine how fast the universe expanded over 11 billion years. DESI’s announcement today is the result of an ongoing international collaboration comprising more than 900 researchers from over 70 institutions, including astronomers at University of California, Santa Cruz with leadership roles in the project. And yet, as big as this news is, they say it’s just the beginning. “If the trends hinted here in this first-year dataset are confirmed in our Year Three analysis, this will be a major discovery,” said cosmologist Alexis Leauthaud, associate professor in UC Santa Cruz's Astronomy and Astrophysics Department. “This is going to be a tremendously exciting time to be part of the DESI collaboration.” Other collaborating professors at UC Santa Cruz include Connie Rockosi and J. Xavier Prochaska, also in Astronomy & Astrophysics—along with a phenomenal team of their undergraduate and graduate students, and postdoctoral researchers who have been visiting the telescope on a regular basis to help with observations. #astronomy #science #space https://lnkd.in/g9CgUKP9 (Video credit: David Kirkby/DESI)
