Enhanced detection limits in the SHINE F150 survey through the Regime Switching Model. Optimizing thresholds and investigating environmental noise
Mariam Sabalbal, Olivier Absil, Carl-Henrik Dahlqvist +1
In high-contrast imaging, a novel detection algorithm for angular differential imaging (ADI) sequences has recently been introduced: the Regime Switching Model (RSM). In this study…
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 SHARDDS survey: limits on planet occurrence rates based on point sources analysis via the Auto-RSM framework
C. -H. Dahlqvist, J. Milli, O. Absil +7
In the past decade, HCI surveys provided new insights about the frequency and properties of substellar companions at separation larger than 5 au. In this context, our study aims to…
Auto-RSM: an automated parameter-selection algorithm for the RSM map exoplanet detection algorithm
Carl-Henrik Dahlqvist, Faustine Cantalloube, Olivier Absil
Most of the high-contrast imaging (HCI) data-processing techniques used over the last 15 years have relied on the angular differential imaging (ADI) observing strategy, along with…
Constraints on the nearby exoplanet Ind Ab from deep near/mid-infrared imaging limits
Gayathri Viswanath, Markus Janson, Carl-Henrik Dahlqvist +16
The past decade has seen increasing efforts in detecting and characterising exoplanets by high contrast imaging in the near/mid-infrared, which is the optimal wavelength domain for…
Exoplanet Imaging Data Challenge: benchmarking the various image processing methods for exoplanet detection
F. Cantalloube, C. Gomez-Gonzalez, O. Absil +23
The Exoplanet Imaging Data Challenge is a community-wide effort meant to offer a platform for a fair and common comparison of image processing methods designed for exoplanet direct…
Improving the RSM map exoplanet detection algorithm: PSF forward modelling and optimal selection of PSF subtraction techniques
Carl-Henrik Dahlqvist, Olivier Absil
High-contrast imaging (HCI) is one of the most challenging techniques for exoplanet detection. It relies on sophisticated data processing to reach high contrasts at small angular s…
RSM detection map for direct exoplanet detection in ADI sequences
Carl-Henrik Dahlqvist, Faustine Cantalloube, Olivier Absil
Beyond the choice of wavefront control systems or coronographs, advanced data processing methods play a crucial role in disentangling potential planetary signals from bright quasi-…
