Together, these phenomena shape the space weather around planets. Because most of the known exoplanets have significantly closer orbital distances than solar system planets, they are often embedded in much harsher particle and radiation environments, leading to stronger interactions between the exoplanet and its surrounding environment. In this talk I will present an overview of how stellar activity and outflows can induce and shape atmospheric escape in exoplanets. I will focus mostly on close-in gas giant planets, whose escaping atmospheres are somewhat easier to observe. I will then discuss how the observability of atmospheric escape, through spectroscopic transits, evolve on billions of years timescales.SeriesProf. Aline VidottoProf. Aline VidottoTue, 19 Mar 2024 17:00:00 +00002024-03-19 05:00Understanding the matter distribution in the Universe on small scaleshttp://iactalks.iac.es/talks/view/1746http://iactalks.iac.es/img/thumbs/-mini.jpghttp://iactalks.iac.es/talks/view/1746In the field of modern cosmological studies, we like to think that we live in an era of "precision cosmology." However, our understanding of matter distribution on small scales is not quite there yet. This limitation stems from the feedback effects of supernovae and supermassive black holes, which alter the matter distribution on scales smaller than a few Mpc and impact star formation and galaxy evolution. I will discuss how surveys such as Subaru-PFS and DESI will enhance our understanding of the Universe's matter distribution. By observing galaxies and AGNs, we can infer the distribution of dark matter, gas, and metals with the support of theoretical modeling and numerical simulations. Specifically, I will explain how we can tighten the constraints on matter distribution on small scales and further refine our understanding of the Lambda-CDM model through IGM/CGM tomography and Lyman-alpha forest analysis. Research Division SeminarProf. Kentaro Nagamine Prof. Kentaro Nagamine Thu, 21 Mar 2024 10:30:00 +00002024-03-21 10:30TBDhttp://iactalks.iac.es/talks/view/1748http://iactalks.iac.es/img/thumbs/-mini.jpghttp://iactalks.iac.es/talks/view/1748Zoom Meeting: https://rediris.zoom.us/j/92460128350?pwd=ZUlhMi91OTZZQXo3bWlZQXJpT1h2QT09 Meeting ID: 924 6012 8350 Passcode: 197895Research Division SeminarDr. Mireia MontesDr. Mireia MontesThu, 04 Apr 2024 10:30:00 +01002024-04-04 10:30Seminario de Instrumentación: ATLAS-IAChttp://iactalks.iac.es/talks/view/1755http://iactalks.iac.es/img/thumbs/-mini.jpghttp://iactalks.iac.es/talks/view/1755En esta charla se va a presentar los telescopios ATLAS y su integración en la red ATLAS dirigida por la Universidad de Hawaii.
