A technique to detect periodic and non-periodic ultra-rapid flux time variations with standard radio-astronomical data

Ermanno F. Borra, Jonathan D. Romney, Eric Trottier

We demonstrate that extremely rapid and weak periodic and non-periodic signals can easily be detected by using the autocorrelation of intensity as a function of time. We use standa…

Radio interferometric observation of an asteroid occultation

Jorma Harju, Kimmo Lehtinen, Jonathan Romney +5

The occultation of the radio galaxy 0141+268 by the asteroid (372) Palma on 2017 May 15 was observed using six antennas of the Very Long Baseline Array (VLBA). The shadow of Palma…

Astrometry of Cassini with the VLBA to Improve the Saturn Ephemeris

Dayton L. Jones, William M. Folkner, Robert A. Jacobson +4

Planetary ephemerides have been developed and improved over centuries. They are a fundamental tool for understanding solar system dynamics, and essential for planetary and small bo…

VLBA Astrometric Observations of the Cassini Spacecraft at Saturn

D. L. Jones, E. Fomalont, V. Dhawan +5

The planetary ephemeris is an essential tool for interplanetary spacecraft navigation, studies of solar system dynamics (including, for example, barycenter corrections for pulsar t…

VLBA Continuum and H I Absorption Observations of the Ultra-Luminous Infrared Galaxy IRAS 17208-0014

E. Momjian, J. D. Romney, C. L. Carilli +2

We present phase-referenced VLBI observations of the radio continuum emission from, and the neutral hydrogen 21 cm absorption toward, the Ultra-Luminous Infrared Galaxy IRAS 17208-…

Global VLBI Observations of the High Velocity HI Absorption Toward NGC 1275

E. Momjian, J. D. Romney, T. H. Troland

We present global VLBI observations of the ~8100 km s HI absorption feature detected toward the strong radio nucleus 3C 84 of NGC 1275 in the Perseus cluster (${V_{\rm sys}\…
