Inverse-problem versus principal component analysis methods for angular differential imaging of circumstellar disks. The mustard algorithm
Sandrine Juillard, Valentin Christiaens, Olivier Absil
Circumstellar disk images have highlighted a wide variety of morphological features. Recovering disk images from high-contrast angular differential imaging (ADI) sequences are howe…
The Enhanced Resolution Imager and Spectrograph for the VLT
R. Davies, O. Absil, G. Agapito +81
ERIS, the Enhanced Resolution Imager and Spectrograph, is an instrument that both extends and enhances the fundamental diffraction limited imaging and spectroscopy capability for t…
The ESO's Extremely Large Telescope Working Groups
Paolo Padovani, Michele Cirasuolo, Remco van der Burg +82
Since 2005 ESO has been working with its community and industry to develop an extremely large optical/infrared telescope. ESO's Extremely Large Telescope, or ELT for short, is a re…
Lessons learned from the NEAR experiment and prospects for the upcoming mid-IR HCI instruments
Prashant Pathak, Markus Kasper, Olivier Absil +6
The mid-infrared (IR) regime is well suited to directly detect the thermal signatures of exoplanets in our solar neighborhood. The NEAR experiment: demonstration of high-contrast i…
NA-SODINN: a deep learning algorithm for exoplanet image detection based on residual noise regimes
Carles Cantero, Olivier Absil, Carl-Henrik Dahlqvist +1
Supervised deep learning was recently introduced in high-contrast imaging (HCI) through the SODINN algorithm, a convolutional neural network designed for exoplanet detection in ang…
The JWST Early Release Science Program for Direct Observations of Exoplanetary Systems: Best Practices for Data Collection in Cycle 2 and Beyond
Sasha Hinkley, Beth Biller, Andrew Skemer +35
We present a set of recommended best practices for JWST data collection for members of the community focussed on the direct imaging and spectroscopy of exoplanetary systems. These…
