📃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.

Unveiling the Cosmic Enigma: Astrophysics and the Mysteries of Dark Matter : In the vast expanse of astrophysics, the exploration of the cosmos goes beyond the ordinary, delving into the profound mysteries that shape our understanding of the universe. At the forefront of this scientific frontier lies the enigma of dark matter, an invisible and elusive substance that significantly influences the cosmic tapestry. Astrophysics: Beyond Observation to Understanding : Astrophysics is not merely about stargazing; it's a journey into the fundamental principles governing celestial bodies and the very fabric of space and time. The discipline employs advanced tools and technologies, from cutting-edge telescopes to particle detectors, to unravel the complexities of the universe. Dark Matter: The Unseen Force : Dark matter, unlike the matter we observe in stars and galaxies, does not emit light or interact with electromagnetic forces. Instead, its presence is inferred through gravitational effects on visible matter. This invisible entity plays a pivotal role in shaping the large-scale structure of the universe, yet its nature remains one of the most intriguing puzzles in contemporary astrophysics. Connecting Theoretical Frameworks with Observational Realities : The evidence supporting dark matter's existence extends to the cosmic microwave background radiation (CMB), a faint glow from the early universe. Patterns in the CMB align with the presence of dark matter, providing a crucial link between theoretical predictions and observational data. Collaborative Endeavors in Particle Physics : The quest to understand dark matter transcends traditional astrophysics, involving collaboration with particle physicists. Experiments like the Large Hadron Collider aim to detect particles that may constitute dark matter, bridging the gap between the macrocosm and the microcosm. The Unending Journey : As observational tools become more sophisticated and theoretical models refine, the exploration of dark matter remains a profound and challenging endeavor. The pursuit of understanding dark matter showcases the synergy between astrophysics and particle physics, pushing the boundaries of our knowledge about the fundamental nature of the universe. In this era of scientific discovery, the mysteries of astrophysics and dark matter beckon us to embark on a journey that transcends the limits of our understanding. As we unveil the secrets of the cosmos, we contribute not only to scientific progress but also to a deeper appreciation of the wonders that surround us. The cosmic enigma continues to inspire, reminding us that in the pursuit of knowledge, the universe is our limitless playground. #Astrophysics #DarkMatter #scientificdiscovery #snsinstitutions #snsdesignthinkers #snsct #snsmct

✨🎙📻 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

I am so proud of my husband Vuk Mandic who is one of the leaders of KAPEMNI, a newly funded NSF program to provide a pathway for Native American students into graduate school in STEM disciplines, in particular astrophysics. "Kapemni is a Dakota word for “to twist” or “to spin.” In Dakota sky knowledge, a Kapemni is a symbol of mirroring between earth and sky. It is drawn as two teepees connected at their apex. The bottom one represents the Earth, the top one is upside down and represents the sky. The apex is a point of passage between these two aspects of the world."

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
