ARRAKIHS

What is #ARRAKIHS? 🟣ARRAKIHS is the first @esa's Science Programme mission led from Spain, specifically from @IFCA_CSIC_UC 🔍Focus on imaging faint galaxies nearby, ARRAKIHS aims to provide crucial measurements for testing open questions in cosmology. 🌌 #SpaceExploration

#8M #InternationalWomensDay #ARRAKIHS

Did you miss Raul Infante (@CEFCA_OAJ) talking yesterday about #ARRAKIHS on #LaCuriosidadSalvoAlGato on @aragontv? 📺 Here’s the link to the program — he appears starting at 16:43 👇 alacarta.aragontelevision.es/programas/la-c…

To mark the International Day of Women and Girls in Science (#11F), we’ve created a memory challenge. You’ll need to match 6 female astrophysicists with their discoveries 💜🔭👩🏽‍🔬 Are you ready?: bit.ly/4qO4N7j

The penguin has been found… and it brought great news!​ 🐧📚 The ARRAKIHS Instrument iPDR data package has been officially delivered on time! ⚡️ Congratulations to everyone who contributed to this amazing work! #NihilistPenguin #iPDR #ARRAKIHS #Instrument

How do we prepare a space mission before it observes the Universe? 🤔 With simulations. ARTEMIS simulations + machine learning help predict the properties of faint galaxy halos, preparing us for future ARRAKIHS observations 🌌 🔗 Read it here: arrakihs-mission.eu/2026/01/13/emu…

🚀 Exciting Opportunity Alert! We're expanding our team and looking for a Postdoctoral Position in the detector Characterization Group, at @_IFAE. ➡️ Click here to apply: ifae.es/careers/jobs/2… #hiring #joboffer

✨How many galaxies should #ARRAKIHS observe? Simulations suggest ~80–84 gives a strong chance of capturing the diverse range of stellar halos needed for significant science, a smart balance of ambition and feasibility 🚀🌌 🔗 arrakihs-mission.eu/2025/12/19/how…

The ARRAKIHS Mission Consortium wishes you a happy 2️⃣0️⃣2️⃣6️⃣!! 🎉🎊 #HappyNewYear

🔭 New research shows that AI models like SAM can measure galaxy sizes with ~1% accuracy. This could be key for ARRAKIHS, helping detect faint halos, tidal streams, and other low–surface-brightness features that trace galactic evolution and dark matter. 📲 bit.ly/4pZR113

#Arrakihs is now in study phase, targeting a launch date in 2030. 3/ #CM25

#Arrakihs will image more than 75 nearby Milky Way-like galaxies & their surroundings, using two innovative, near-identical binocular telescope assemblies. It will carry out a survey at visible & infrared wavelengths, far exceeding what's currently possible from ground-based telescopes. 2/ #CM25

In 2022, #Arrakihs was selected as a fast mission under #CosmicVision. By imaging Milky Way-type galaxies in the nearby Universe, Arrakihs will provide important measurements to address key questions in galaxy formation theory. 1/ #CM25

🎂ARRAKIHS turns 3️⃣ In just three years, the mission has advanced from early planning to instrument definition and ground-based observations, setting the foundation for its scientific objectives 🚀 Looking forward to the next milestones 💫

A major boost for ARRAKIHS: The HARKONENS Project 💫 Led by Santi Roca Fábrega (Lund Univ.) and Corentin Cadiou (IAP), has been awarded 234M CPU hours on @EuroHPC_JU to run next-gen cosmological simulations supporting our mission. 🔗 arrakihs-mission.eu/2025/11/17/a-m…

Our colleague Raúl Infante (@CEFCA_OAJ), contributor to the Data Analysis (DAT), Coordination with other Surveys (CDR) and Data Reduction (RED-SCI) work packages, gave a talk at a @UNED course on November 4th 🤗

HAPPY DARK MATTER DAY!! 🎉 Today, October 31st, we celebrate one of the greatest #mysteries of the #universe! 🌌 #DarkMatterDay #ARRAKIHS #ARRAKIHSmission #October31st

Our PI, Rafael Guzmán (@IFCA_CSIC_UC ), presented the #ARRAKIHSmission at the @aee_gob . We thank Juan Carlos Cortés (AEE), and Isabel Pérez Grande (AEE) , for their support and for fostering collaboration within Spain’s growing space ecosystem. 🔗 sl1nk.com/Sc443

When small galaxies meet big ones 💫 The #AGORA project explores how dwarf satellite galaxies stop forming stars , a process called “quenching”. What #ARRAKIHS will help us uncover. 📌 Ramón Rodríguez Cardoso (@unicomplutense, @infoGMV_es) 🔗 goo.su/R0s4d

Last Friday, some of our @IFCA_CSIC_UC researchers took part in the #ERN2025 in 📍Santander. Diego Herranz , Biuse Casaponsa, and Abram Pérez were with the little ones, doing #ARRAKIHS puzzles as part of the science challenge 🧩 Thank you for your collaboration! 🙌🏼
