A Near-Infrared Spectroscopic Survey of K-selected Galaxies at z ~ 2.3: Redshifts and Implications for Broadband Photometric Studies
(2008)
Using the Gemini Near-InfraRed Spectrograph (GNIRS), we have completed a near-infrared spectroscopic survey for K-bright galaxies at z~2.3, selected from the MUSYC survey. We derived spectroscopic redshifts from emission ...
A near-infrared spectroscopic survey of K-selected galaxies at z similar to 2.3: Redshifts and implications for broadband photometric studies
(UNIV CHICAGO PRESS, 2008-04-10)
Using the Gemini Near-Infrared Spectrograph (GNIRS), we have completed a near-infrared spectroscopic survey for K-bright galaxies at z similar to 2.3 selected from the MUSYC survey. We derived spectroscopic redshifts from ...
Rr lyrae stars as probes of structure in the milky way galaxy: tools and applicatións
(2015)
We present a compendium of two works regarding computational approach to RR Lyrae in surveys. We believe that improving programming skills and statistical knowledge is fundamental to tackle the challengesthat future surveys ...
Desafios da iluminação pública no Brasil e nova técnica de projetos luminotécnicos fundamentada na fotometria mesópica

Uma abordagem estatística sobre a estimação de redshifts de quasares usando dados do S-PLUS
(Universidade Federal de São CarlosUFSCarCâmpus São CarlosEstatística - Es, 2022-09-08)
Redshift is a cosmic index used to measure distances to astronomical objects. The study of this quantity is important for the understanding of the expansion of the Universe and the current objective of the stars, according ...
Physical parameters for RR Lyrae stars in the sdss filter system
(2013)
We present a calibration of the metallicity and physical parameters (temperature, luminosity, gravity, mass, radius) for RR Lyrae stars using the ugriz sdss photometric system. Our work is based on calculations of synthetic ...
Correlational study between model variables and observable quantities of magnetar-powered H-rich supernovae

Analysis of the Cramér-Rao Bound in the Joint Estimation of Astrometry and Photometry
(The Astronomical Society of the Pacific, 2014)
In this paper, we use the Cramér-Rao lower uncertainty bound to estimate the maximum precision that could be achieved on the joint simultaneous (or two-dimensional) estimation of photometry and astrometry of a point source ...
