TL;DR: The results of the Gemini Deep Planet Survey as mentioned in this paper were obtained with the Altair adaptive optics system at the Gemini North telescope, and angular differential imaging was used to suppress the speckle noise of the central star.

Journal ArticleDOI
An atlas of mid-infrared spectra of galaxy nuclei
TL;DR: In this paper, the spectral energy distributions of 60 galaxies for which 8-13 μm and in some cases 17-23 μm, spectra have been obtained, and these IR bright galaxies are discussed in terms of their spectral properties in the mid-IR and the relationship with their far-IR properties.
Journal ArticleDOI
A population of very young brown dwarfs and free‐floating planets in Orion
TL;DR: The results of a very deep imaging survey of the Trapezium cluster in the IJH bands, using the UKIRT high-resolution camera UFTI, are described in this paper.
Journal ArticleDOI
Infrared Spectroscopy of Substellar Objects in Orion
TL;DR: In this article, the authors present broad band spectra of a sample of 21 low luminosity sources in the Trapezium cluster, with masses in the range 0.008 - 0.10 M⊙ (assuming an age of 1 Myr).
