GPI 2.0: Characterizing Self-Luminous Exoplanets Through Low-Resolution Infrared Spectroscopy

Kavli Affiliate: Arlene Aleman | First 5 Authors: Arlene Aleman, Bruce Macintosh, Mary Anne Limbach, Mark Marley, Jeffrey Chilcote | Summary: Direct imaging characterization of extrasolar planets is often done at low spectral resolution. We model the spectrograph for the Gemini Planet Imager upgrade (GPI 2.0) and assess the instrument’s potential for allowing observers to […]

The Atacama Cosmology Telescope: limits on dark matter-baryon interactions from DR4 power spectra

Kavli Affiliate: Blake Sherwin | First 5 Authors: Zack Li, Rui An, Vera Gluscevic, Kimberly K. Boddy, J. Richard Bond | Summary: Diverse astrophysical observations suggest the existence of cold dark matter that interacts only gravitationally with radiation and ordinary baryonic matter. Any nonzero coupling between dark matter and baryons would provide a significant step […]
