Characterizing Earth analogs may require a moderate or high-resolution spectrograph
Jean-Baptiste Ruffio, Sarah Steiger, Corey Spohn +16
A primary goal of the Habitable Worlds Observatory (HWO) is to detect and measure the abundance of biosignature molecules, such as water (H2O) and oxygen (O2), in the atmosphere of…
Ground-Based Mid-IR Direct Imaging: The Origin of the Thermal Background on the Keck II Telescope and Correcting Instrumental Systematics
Jayke S. Nguyen, Quinn M. Konopacky, William Thompson +2
Mid-IR wavelengths are of particular interest to exoplanet science due to the fact they can extend the searchable parameter space to planets that are older and/or colder. However,…
GPI 2.0: Exploring The Impact of Different Readout Modes on the Wavefront Sensor's EMCCD
Clarissa R. Do Ó, Saavidra Perera, Jérôme Maire +26
The Gemini Planet Imager (GPI) is a high contrast imaging instrument that aims to detect and characterize extrasolar planets. GPI is being upgraded to GPI 2.0, with several subsyst…
Estimating Atmospheric Wind Speeds From Gemini Planet Imager AO Telemetry
Zhenxi Du, Saavidra Perera, Daniel Levinstein +6
The Earth's atmosphere is comprised of turbulent layers that result in speckled and blurry images from ground-based visible and infrared observations. Adaptive Optics (AO) systems…
Report of the Working Group on Strategic Exoplanet Initiatives with HST and JWST
Seth Redfield, Natasha Batalha, Björn Benneke +7
This STScI Working Group (WG) was charged with soliciting community feedback and evaluating the strategic planning for exoplanet science with JWST and HST given the high quality of…
Calibration Unit Design for High-Resolution Infrared Spectrograph for Exoplanet Characterization (HISPEC)
Ben Sappey, Quinn Konopacky, Nemanja Jovanovic +13
The latest generation of high-resolution spectrograph instruments on 10m-class telescopes continue to pursue challenging science cases. Consequently, ever more precise calibration…
