SPARC4 control system
Denis Bernardes, Orlando Verducci Junior, Francisco Rodrigues +15
SPARC4 is a new astronomical instrument developed entirely by Brazilian institutions, currently installed on the 1.6-m Perkin-Elmer telescope of the Pico dos Dias Observatory. It a…
CUBES: a UV spectrograph for the future
S. Covino, S. Cristiani, J. M. Alcala' +86
In spite of the advent of extremely large telescopes in the UV/optical/NIR range, the current generation of 8-10m facilities is likely to remain competitive at ground-UV wavelength…
CUBES, the Cassegrain U-Band Efficient Spectrograph
S. Cristiani, J. M. Alcalá, S. H. P. Alencar +74
In the era of Extremely Large Telescopes, the current generation of 8-10m facilities are likely to remain competitive at ground-UV wavelengths for the foreseeable future. The Casse…
CUBES Phase A design overview -- The Cassegrain U-Band Efficient Spectrograph for the Very Large Telescope
Alessio Zanutta, Stefano Cristiani, David Atkinson +51
We present the baseline conceptual design of the Cassegrain U-Band Efficient Spectrograph (CUBES) for the Very Large Telescope. CUBES will provide unprecedented sensitivity for spe…
Astrometric and photometric study of Dias 4, Dias 6 and other five open clusters using ground based and Gaia DR2 data
Wilton S. Dias, Hektor Monteiro, Jacques R. D. Lépine +3
We present a study of 7 southern open clusters based on UBVRI CCD photomety (Johnsons-Cousins system) and Gaia DR2 data. Dias 4, Dias 6 and four other clusters had UBVRI photometri…
Studying focal ratio degradation of optical fibers for Subaru Prime Focus Spectrograph
Jesulino Bispo dos Santos, Antonio Cesar de Oliveira, James Gunn +9
Focal Ration Degradation (FRD) is a change in light angular distribution caused by fiber optics. FRD is important to fiber-fed, spectroscopic astronomical systems because it can ca…
Fiber Optical Cable and Connector System (FOCCoS) for PFS/Subaru
Antonio Cesar de Oliveira, Lígia Souza de Oliveira, Márcio V. de Arruda +29
FOCCoS, Fiber Optical Cable and Connector System, has the main function of capturing the direct light from the focal plane of Subaru Telescope using optical fibers, each one with a…
Discovery of optical pulsations in V2116 Ophiuchi/GX 1+4
Francisco J. Jablonski, Marildo G. Pereira, Joao Braga +1
We report the detection of pulsations with s period in V2116 Oph, the optical counterpart of the low-mass X-ray binary GX 1+4. The pulsations are sinusoidal with modulat…
