Ultra-pure digital sideband separation at sub-millimeter wavelengths
(EDP Sciences, 2015)
Context. Deep spectral-line surveys in the mm and sub-mm range can detect thousands of lines per band uncovering the rich chemistry
of molecular clouds, star forming regions and circumstellar envelopes, among others ...
The antenna DSA 3 and its potential use for Radio Astronomy
(Asociacion Argentina de Astronomia, 2011-10)
The European Space Agency (ESA) will inaugurate its third Deep Space Antenna (DSA 3) by the end of 2012. DSA 3 will be located in Argentina near the city of Malarg"ue in the Mendoza province. While the instrument will ...
Two year Cosmology Large Angular Scale Surveyor (CLASS) observations: long timescale stability achieved with a front-end variable-delay polarization modulator at 40 GHz
(IOP, 2021)
The Cosmology Large Angular Scale Surveyor (CLASS) is a four-telescope array observing the largest angular scales
(2 ℓ 200) of the cosmic microwave background (CMB) polarization. These scales encode information ...
A treatment procedure for Gemini North/NIFS data cubes: application to NGC 4151
(Oxford University PressOxford, 2014)
We present a detailed procedure for treating data cubes obtained with the Near-Infrared Integral
Field Spectrograph (NIFS) of the Gemini North telescope. This process includes the following
steps: correction of the ...
Lessons learned from SPHERE for the astrometric strategy of the next generation of exoplanet imaging instruments
(Spie-Soc Photo-Optical Instrumentation Engineers, 2021)
Measuring the orbits of directly imaged exoplanets requires precise astrometry at the milliarcsec level over long periods of time due to their wide separation to the stars (greater than or similar to 10 au) and long orbital ...
Multi-Conjugate Adaptive Optics VLT imaging of the distant old open cluster FSR 1415
(WILEY-BLACKWELL PUBLISHING, INC, 2008)
We employ the recently installed near-infrared Multi-Conjugate Adaptive Optics demonstrator (MAD) to determine the basic properties of a newly identified, old and distant, Galactic open cluster (FSR 1415). The MAD facility ...
Mapping low- and high-density clouds in astrophysical nebulae by imaging forbidden line emission
(WILEY-BLACKWELL PUBLISHING, INC, 2009)
Emission line ratios have been essential for determining physical parameters such as gas temperature and density in astrophysical gaseous nebulae. With the advent of panoramic spectroscopic devices, images of regions with ...
Intragroup diffuse light in compact groups of galaxies - II. HCG 15, 35 and 51
(WILEY-BLACKWELL, 2008)
This continuing study of intragroup light in compact groups of galaxies aims to establish new constraints to models of formation and evolution of galaxy groups, specially of compact groups, which are a key part in the ...
