Component-resolved Near-infrared Spectra of the (22) Kalliope System
We observed (22) Kalliope and its companion Linus with the integral-field spectrograph OSIRIS, which is coupled to the adaptive optics system at the W.M. Keck 2 telescope on March 25 2008. We present, for the first time, component-resolved spectra acquired simultaneously in each of the Zbb (1-1.18μm), Jbb (1.18-1.42μm), Hbb (1.47-1.80μm), and Kbb (1.97-2.38μm) bands. The spectra of the two bodi...
متن کاملNear-Infrared Spectra of Ultraluminous Infrared Galaxies.
Near-infrared spectra with a resolution of lambda&solm0;Deltalambda approximately 1100 in the rest-wavelength range of 1.8-2.2 µm have been obtained for a complete sample of 33 ultraluminous infrared galaxies (ULIRGs). Of the 33 objects observed, two show evidence of a central active galactic nucleus (AGN) through either a broad Paschen-alpha line or emission in the 1.963 µm fine structure of [...
متن کاملNear infrared spectra of the Orion bar
We have used the LONGSP spectrometer on the 1.5m TIRGO telescope to obtain long slit spectra in the J, H, and K wavelength bands towards two positions along the Orion bar. These data have been supplemented with images made using the ARNICA camera mounted on TIRGO as well as with an ESO NTT observation carried out by Dr A. Moorwood. We detect a variety of transitions of hydrogen, helium, OI, FeI...
متن کاملIntramolecular Dynamics from Eigenstate-resolved Infrared Spectra
Understanding intramolecular energy flow in molecules is one of the central goals of chemical physics. Statistical theories [such as Rice-Ramsperger-Kassel-MarCus (RRKM) theory] of unimolecular reaction rates, which assume that the vibrational degrees of freedom rapidly exchange energy, have proved extremely successful (1). Recent work on small molecules has provided rigorous tests of these the...
متن کاملMultispectral System for Recovering Near-Infrared Reflectance Spectra
In this paper, we analyze an experimental system for recovering the reflectance spectra of samples in the nearinfrared region of the spectrum (NIR, 800-1000 nm). Recently, CCD cameras with improved response in the NIR have been manufactured. It is therefore possible to use this standard instrumentation to obtain information on samples in this region. The setup used in this work consisted of a c...
