ARRAKIHS prepares for orbit! 🛰️ A technical training campaign at Javalambre Observatory ( #CEFCA ) tested the iSIM-170 camera, a key instrument for the mission to study dark matter from space. 🔗 bit.ly/45AxiOa #ARRAKIHS #ESA #DarkMatter #iSIM170 #Astrophysics #OAJ

How faint can we go? With #ARRAKIHS + VIS2, we can detect #galaxy features as dim as 31 mag/arcsec² 🌌 Using mock images, we subtracted stars, cleaned backgrounds, and applied astnoisechisel to extract even the faintest signals. Credit: Helena Domínguez Sánchez

Dark matter ≠ Dark energy But what’s the difference?🤔 Alex Riley (@durham-university.bsky.social), member of WP COS and GAL, breaks it down. 📹: youtu.be/unN_h1VhbjQ

🎙️This Sunday at 11 AM, ARRAKIHS goes on air! Pepa Fernández interviews our Principal Investigator, Rafael Guzmán, on Spanish national radio at "No es un día cualquiera". #rne #neudc

🛰️ How will #ARRAKIHS reveal the invisible #universe? Hugo Rosado (DEIMOS), Mission Planning Coordinator, explains how the mission will observe faint galaxies and uncover the structure of #darkmatter once in orbit. 🎥 youtu.be/a3IbBdOHY04 #ESA #telescope #spacemission

Great week at #SATLANTIS for the #ARRAKIHS Instrument Intermediate Design and Analyses Review (IIDAR) workshop 🛰️ Key step ahead of PDR, with progress, collaboration & good conversations in Leioa. Thanks to all involved!🤗 🔗 www.arrakihs-mission.eu/2025/06/13/a... @esa.int #SpaceMission #workshop

💫 First observations with the Ground Demonstrator (OGD) at the Javalambre Astrophysical Observatory! 💫 1️⃣ M101, Pinwheel Galaxy 2️⃣ M42, Orion Nebula 3️⃣ M81, Bode’s Galaxy #astrophysics #groundobservations #ARRAKIHS #OGD @cefca-oaj.bsky.social #Satlantis @ifca.es #space #mission

The ground-based demonstrator of @arrakihs-mission.eu is already capturing images! 🌌 The @esa.int mission, led by @ifca.es, will provide key information about dark matter. Researchers from #IEEC at @ice-csic.bsky.social are taking part 🔝 @cefca-oaj.bsky.social 👉 www.ieec.cat/en/arrakihs-...

🚀 #ARRAKIHS begins its scientific prepararion at the Javalambre Observatory! A ground-based replica of the space camera is now operational—testing key tools and strategies ahead of launch. 🔗 goo.su/jB9Pvt @ifca.es @cefca-oaj.bsky.social #Satlantis #groundobservations #galaxy #space #mission

⚡️Are you into stellar streams, galaxies and dark matter? We’re offering a JAE Intro 2025 #research #scholarship at @ifca.es 🔍 Topic: Analysis of stellar streams 📍 Location: Santander, Spain ⏳ Duration: 7 months 💶 Grant: 600 €/month 🔗 goo.su/nsUJk @csic.es @csicdivulga.bsky.social

The 4th ARRAKIHS Consortium meeting took place at @univie.ac.at! 73 team members met in person to advance #mission planning and scientific goals. 🚀 🔗 www.arrakihs-mission.eu/2025/05/02/4... #ARRAKIHS #darkmatter #spacemission #consortium #meeting #vienna

We joined the #iconicobjects trend with the iSIM-170 camera, developed by #Satlantis and key to the #ARRAKIHS mission. It’s designed to reveal the faintest light in the universe using a unique binocular #telescope. 📦 Would you collect it? 👀 #ai #darkmatter

A few days ago, Santi Roca-Fàbrega (Lund University), our #Cosmological Simulations WP Coordinator, participated in #SpaceResearchersSweden2025 in #Kiruna, where he presented #ARRAKIHS to the scientific community and representatives from the #SwedishSpaceAgency.

Denis Erkal (@derkal.bsky.social), one of our contributors, is an expert in galaxy modeling at the @uniofsurrey.bsky.social He has given a talk focused on the Milky Way’s formation and dark matter properties 🌌 #ARRAKIHS #GalaxyModels #DarkMatter #MilkyWay

ARRAKIHS at #CosmosClub! 🚀 Our colleague Rebekka Coles-Bieri (UZH) introduced the #mission to a broader audience, sparking discussion and engagement! ✨🔭 @raumschiff.bsky.social #ARRAKIHS #DarkMatter #Cosmos #SXS #ESA #spacemission

Because of this #internationalwomensday, three of the #ARRAKIHS women share with us their stories, their dreams… The universe has no limits. Neither do we ✨💜 👤Rebekka Coles-Bieri (UZH), Laura Burgos (Satlantis) and Paola Kögl (KOEGL Space) #8M #IWD2025 #darkmatter ▶️https://youtu.be/IhKz1QhA5VQ
