TL;DR: In this paper, the authors used principal component analysis algorithms alongside angular and spectral differential imaging to reduce the intensity of the starlight and reveal faint companions, and injected synthetic planets with known flux to evaluate the self-subtraction caused by their data reduction and to determine the 5σ contrast in the J band versus separation for reduced images.
Characterizing brown dwarf companions with IRDIS long-slit spectroscopy: HD 1160 B and HD 19467 B

TL;DR: In this paper, Coronagraphic long-slit spectroscopic observations with SPHERE of two substellar companions, HD 1160 B and HD 19467 B, are presented.

TL;DR: Researchers detect a warp in the debris disk around HD110058 using VLT/SPHERE and HST/STIS data, suggesting a possible planetary-mass companion, with the warp's asymmetry and inclination indicating an inner perturber origin.

TL;DR: In this paper, a new set of high-contrast data obtained during the commissioning of the SPHERE instrument at the Very Large Telescope (VLT) was used for an extended comparison of GJ 758 B with empirical objects and four families of atmospheric models.
