Infrared spectroscopy of dust in the Taurus dark clouds: ice and silicates
Des spectres IR representant les caracteristiques de la poussiere pour la glace a 3 μm et le silicate a 10 μm sont presentes pour des etoiles en direction du complexe de nuages sombres Taurus,Expand

A population of very young brown dwarfs and free‐floating planets in Orion
We describe the results of a very deep imaging survey of the Trapezium cluster in the IJH bands, using the UKIRT high-resolution camera UFTI. Approximately 32 per cent of the 515 point sourcesExpand

TORUS AND ACTIVE GALACTIC NUCLEUS PROPERTIES OF NEARBY SEYFERT GALAXIES: RESULTS FROM FITTING INFRARED SPECTRAL ENERGY DISTRIBUTIONS AND SPECTROSCOPY
We used the CLUMPY torus models and a Bayesian approach to fit the infrared spectral energy distributions and ground-based high angular resolution mid-infrared spectroscopy of 13 nearby SeyfertExpand

NGC 4418; a very extinguished galaxy
On presente des observations du noyau de NGC 4418 qui montrent qu'il s'agit peut-etre de la premiere vraie galaxie IR. Le spectre optique ne revele que quelques raies d'absorption stellaires et deExpand

MID-INFRARED POLARIZATION STUDIES OF SGRA : A THREE-DIMENSIONAL STUDY OF THE CENTRAL PARSEC
Thermal emission from magnetically aligned dust grains produces the observed mid-infrared polarization in the northern arm and east–west bar of SgrA West; recent arcsecond-resolution imagingExpand

The Extended Mid-Infrared Structure of the Circinus Galaxy
We present subarcsecond resolution mid-IR images of the Circinus galaxy at 8.74 and 18.33 μm. We resolve extended emission at both wavelengths, extending ~2'' from each side of the nucleus in anExpand

A deep survey of brown dwarfs in Orion with Gemini
We report the results of a deep near infrared (JHK) survey of the outer parts of the Trapezium Cluster with Gemini South/Flamingos. 396 sources were detected in a 26 arcmin 2 area, including 138Expand

Optical spectroscopic classification and membership of young M dwarfs in star‐forming regions
The spectral type is a key parameter in calibrating the temperature which is required to estimate the mass of young stars and brown dwarfs. We describe an approach developed to classify low-massExpand
