Soluções de Gödel e tipo-Gödel no formalismo de Brans-Dicke
(Universidade Federal de Mato GrossoBrasilInstituto de Física (IF)UFMT CUC - CuiabáPrograma de Pós-Graduação em Física, 2016-03-04)
In this work, behaviour and main properties of Gödel and Gödel-like solutions, which describe homogenous and stationary space-times with rotation, in the gravitational Brans-Dicke formalism, which is one of the first and ...
GW Librae: a unique laboratory for pulsations in an accreting white dwarf
(2016)
Non-radial pulsations have been identified in a number of accreting white dwarfs in cataclysmic variables. These stars offer insight into the excitation of pulsation modes in atmospheres with mixed compositions of hydrogen, ...
A fully sampled ë21 cm linear polarization survey of the southern sky
(Edp Sciences, 2008-12)
Context: Linear polarization of Galactic synchrotron emission provides valuable information on the Galactic magnetic field and on the properties of the Galactic magneto-ionic medium. Polarized high-latitude Galactic emission ...
A 3-D perspective to the internal properties of low and high-redshift galaxies
(2019)
In the present work, I study the morpho-kinematics of two moderate galaxy samples at
low- and high-redshift. I analyse the internal kinematics of these galaxies aiming to find
possible correlations between the kinematic ...
The Q/U Imaging ExperimenT: Polarization Measurements of the Galactic Plane at 43 and 95 GHz
(IOP Publishing, 2015)
We present polarization observations of two Galactic plane fields centered on Galactic coordinates (l, b) = (0 degrees, 0 degrees) and (329 degrees, 0 degrees) at both Q (43 GHz) and W bands (95 GHz), covering between 301 ...
Origin of primordial magnetic fields
(AMER PHYSICAL SOC, 2008)
Magnetic fields of intensities similar to those in our galaxy are also observed in high redshift galaxies, where a mean field dynamo would not have had time to produce them. Therefore, a primordial origin is indicated. It ...
Exploiting The Synergy Between Alma And Vlt Ao-Ifu Imaging Using Samples Of High-Z Star-Forming Galaxies
We initially requested funding for a postdoc position to work with spatially resolved imaging in high-z galaxies making use of three approved proposals from ALMA and VLT-SINFONI (AO-aided). Thirty galaxies are selected ...
Diffuse molecular gas at high redshift. Detection of CO molecules and the 2175 Å dust feature at z = 1.64
(2009)
We present the detection of carbon monoxide molecules (CO) at towards the quasar SDSS J160457.50+220300.5 using the Very Large Telescope Ultraviolet and Visual Echelle Spectrograph. We detected CO absorption in at least ...
