Probing the gravitational redshift with an Earth-orbiting satellite
D. A. Litvinov, V. N. Rudenko, A. V. Alakoz +45
We present an approach to testing the gravitational redshift effect using the RadioAstron satellite. The experiment is based on a modification of the Gravity Probe A scheme of nonr…
PKS 1954-388: RadioAstron Detection on 80,000 km Baselines and Multiwavelength Observations
P. G. Edwards, Y. Y. Kovalev, R. Ojha +24
We present results from a multiwavelength study of the blazar PKS 1954-388 at radio, UV, X-ray, and gamma-ray energies. A RadioAstron observation at 1.66 GHz in June 2012 resulted…
Planetary Radio Interferometry and Doppler Experiment (PRIDE) technique: A test case of the Mars Express Phobos fly-by
Dmitry A. Duev, Sergei V. Pogrebenko, Giuseppe Cimò +33
The closest ever fly-by of the Martian moon Phobos, performed by the European Space Agency's Mars Express spacecraft, gives a unique opportunity to sharpen and test the Planetary R…
Interstellar scintillation is an indicator of astrometric stability
Robert Schaap, Stanislav Shabala, Simon Ellingsen +2
We examine the relationship between astrometric stability and astrophysical properties in flat-spectrum radio-loud quasars making up the celestial reference frame. We use position…
Discovery of four water masers in the Small Magellanic Cloud
S. L. Breen, J. E. J. Lovell, S. P. Ellingsen +3
We report the detection of four water masers within the Small Magellanic Cloud (SMC); two discovered with the 70-m Tidbinbilla radio telescope, and two discovered with the Australi…
PKS 2123-463: a confirmed gamma-ray blazar at high redshift
F. D'Ammando, A. Rau, P. Schady +11
The flat spectrum radio quasar (FSRQ) PKS 2123-463 was associated in the First Fermi-LAT source catalog with the gamma-ray source 1FGL J2126.1-4603, but when considering the full f…
