The Roman Coronagraph Community Participation Program: Using the Zernike wavefront sensor for a full characterisation of the Roman Space Telescope and the Coronagraph Instrument
Arthur Vigan, Alexis Bidot, Vincent Chambouleyron +4
The Roman Space Telescope Coronagraph Instrument (CGI) will demonstrate a series of technologies and techniques to enable the direct detection of reflected-light planets with space…
The Roman Coronagraph Community Participation Program: corgisim - a simulation suite for the Nancy Grace Roman Space Telescope Coronagraph Instrument
Jingwen Zhang, Sophie Noiret, Maxwell A. Millar Blanchaer +14
NASA's Roman Space Telescope will feature a pathfinder Coronagraph Instrument to demonstrate advanced high-contrast imaging from space, paving the way for future missions like the…
ForMoSA: Forward Modeling tool for Spectral Analysis
ForMoSA Collaboration, Simon Petrus, Paulina Palma-Bifani +9
ForMoSA (FORward MOdeling tool for Spectral Analysis) is an open-source Python package to fit spectroscopic and photometric observations using a Bayesian framework. It can utilize…
ANDES, the high-resolution spectrograph of the ELT: simulated performance of the CORO module and overview of the high-contrast capabilities for exoplanet observations
M. N'Diaye, A. Simonnin, A. Spang +19
We present the simulated performance of the coronagraph (CORO) module for ANDES, the Extremely Large Telescope (ELT) high-resolution spectrograph. ANDES aims to address a broad ran…
SAXO+, the second-stage adaptive optics for SPHERE: NCPA compensation and dark-hole loop with a pyramid wavefront sensor
Johan Mazoyer, Charles Goulas, Raphaël Galicher +21
The SAXO+ upgrade of the VLT/SPHERE adaptive optics system introduces a second-stage near-infrared pyramid wavefront sensor to improve high-contrast imaging, making accurate calibr…
ESCAPE project: testing active observing strategies for high-contrast imaging in space on the HiCAT testbed
Alexis Lau, Élodie Choquet, Lisa Altinier +6
The Roman Space Telescope will be a critical mission to demonstrate high-contrast imaging technologies allowing for the characterisation of exoplanets in reflected light. It will d…
ESCAPE project. CAPyBARA: a Roman Coronagraph simulator for post-processing methods development
Lisa Altinier, Élodie Choquet, Arthur Vigan +2
The Roman Coronagraph Instrument will be the first space facility equipped with deformable mirrors (DMs). These will lead to reach a contrast of or better in a dark hole…
ESCAPE project: fundamental detection limits of JWST/NIRCam coronographic observations
N. Godoy, E. Choquet, L. Altinier +4
In this study, we explored the fundamental contrast limit of NIRCam coronagraphy observations, representing the achievable performance with post-processing techniques. This limit i…
Direct characterization of young giant exoplanets at high spectral resolution by coupling SPHERE and CRIRES+
G. P. P. L. Otten, A. Vigan, E. Muslimov +19
Studies of atmospheres of directly imaged exoplanets with high-resolution spectrographs have shown that their characterization is predominantly limited by noise on the stellar halo…
K-Stacker, a new way of detecting and characterizing exoplanets with high contrast imaging instruments
H. Le Coroller, M. Nowak, L. Arnold +4
This year, a second generation of coronagraphs dedicated to high-contrast direct imaging of exoplanets is starting operations. Among them, SPHERE, installed at the focus of the UT3…
Simulation of planet detection with the SPHERE IFS
D. Mesa, R. Gratton, A. Berton +13
Aims. We present simulations of the perfomances of the future SPHERE IFS instrument designed for imaging extrasolar planets in the near infrared (Y, J, and H bands). Methods. We us…
