High-contrast adaptive optics (AO) imaging is a powerful technique to probe the
architectures of planetary systems from the outside-in and survey the atmospheres of self …

The Gemini Planet Imager is a dedicated facility for directly imaging and spectroscopically
characterizing extrasolar planets. It combines a very high-order adaptive optics system, a …

High-contrast observations in optical and infrared astronomy are defined as any observation
requiring a technique to reveal a celestial object of interest that is in such close angular …

In this paper, we review the impact of small sample statistics on detection thresholds and
corresponding confidence levels (CLs) in high-contrast imaging at small angles. When …

The direct characterization of exoplanetary systems with high-contrast imaging is among the
highest priorities for the broader exoplanet community. As large space missions will be …

We apply the vectorized non-negative matrix factorization (NMF) method to the post-
processing of the direct imaging data of exoplanetary systems such as circumstellar disks …

Context. Reference-star differential imaging (RDI) is a promising technique in high-contrast
imaging that is thought to be more sensitive to exoplanets and disks than angular differential …

In recent years, there has been intensive research into the direct detection of exoplanets.
Data obtained in the future with high-contrast imaging instruments, optimized for the direct …

We present the results of the Gemini Deep Planet Survey, a near-infrared adaptive optics
search for giant planets and brown dwarfs around 85 nearby young stars. The observations …

We present results from a high-contrast adaptive optics imaging search for giant planets and
brown dwarfs (≳ 1 M Jup) around 122 newly identified nearby (≲ 40 pc) young M dwarfs …
