Extragalactic Background Light: EBL- Accumulated radiation of entire celestial sources from early universe to present epochThe EBL observation is crucial to reveal star formation history ofthe universe.Parameter ValueMission Payload - OpticsD = 35 mm, FoV = 4.2 deg×4.2 deg- Detector (SONY IMX533)Low-noise detector, 3k × 3k formatPointing Stability 10”(1σ) / 1 min (TBC)Communication 1 kbps (Up)/32 kbps (Down) S-band5 Mbps X-band (Mission data Down)Orbit 500 km Solar Synchronous Orbit (TBC)Launch 2025 (TBC)- VERTECS is expected to establish a versatile system served for various astronomical observations.Near-infrared EBL brightness is reportedly several times brighter than integrated light of known galaxies.→ Presence of unknown extragalactic sources, such as Intrahalo Light or First StarsVERTECS mission- Spectral observation in visible wavelength 0.4μm-0.8μm to reveal origin of the EBLEBL sensitivity is determined by [Telescope aperture] × [Field of View].→ Small wide-field telescope for CubeSat can detect the EBL.Main bus (OBC, EPS)- Based on CubeSat heritage at Kyutech (BIRDS, KITSUNE, etc.)AOCS- 1U unit developed through technological front-loading at JAXAFig. 1: Conceptual view of EBLFig. 2: Previous EBL measurements and observation range of VERTECSFig. 3: System block diagramTable: Major system specificationsEBLSurface brightnessTelescope- 2U size wide-field optics and baffle structureEBL brightness
