The Sardinia Radio Telescope: From a Technological Project to a Radio Observatory
I. Prandoni, M. Murgia, A. Tarchi +43
[Abridged] The Sardinia Radio Telescope (SRT) is the new 64-m dish operated by INAF (Italy). Its active surface will allow us to observe at frequencies of up to 116 GHz. At the mom…
Deriving the extinction to young stellar objects using [FeII] near-infrared emission lines. Prescriptions from GIANO high-resolution spectra
Tommaso Pecchioli, Nicoletta Sanna, Fabrizio Massi +1
The near-infrared emission lines of Fe at 1.257, 1.321, and 1.644 m share the same upper level; their ratios can then be exploited to derive the extinction to a line emitt…
Lines and continuum sky emission in the near infrared: observational constraints from deep high spectral resolution spectra with GIANO-TNG
E. Oliva, L. Origlia, S. Scuderi +19
Aims Determining the intensity of lines and continuum airglow emission in the H-band is important for the design of faint-object infrared spectrographs. Existing spectra at low/med…
The fiber-fed preslit of GIANO at T.N.G
A. Tozzi, E. Oliva, L. Origlia +9
Giano is a Cryogenic Spectrograph located in T.N.G. (Spain) and commisioned in 2013. It works in the range 950-2500 nm with a resolving power of 50000. This instrument was designed…
Trade-off study for high resolution spectroscopy in the near infrared with ELT telescopes: seeing-limited vs. diffraction limited instruments
N. Sanna, E. Oliva, F. Massi +2
HIRES, a high resolution spectrometer, is one of the first five instruments foreseen in the ESO roadmap for the E-ELT. This spectrograph should ideally provide full spectral covera…
A GIANO-TNG high resolution IR spectrum of the airglow emission
E. Oliva, L. Origlia, R. Maiolino +19
A flux-calibrated high resolution spectrum of the airglow emission is a practical lambda-calibration reference for astronomical spectral observations. It is also useful for constra…
