Lunar nutation effect defines the sign of the Earth rotation rate for now, but this may change soon
Oleg Titov
The Earth slowly decelerates in its rotation due to the energy dissipation caused by the interaction with the Moon. This leads to the continuous increasing in the length of the mea…
A novel approach for the direct estimation of the instantaneous Earth rotation velocity
Oleg Titov
Very Long Baseline Interferometry (VLBI) measures two standard observables: group delay and fringe frequency (delay rate). While group delay is widely used to estimate a broad rang…
Quantum-enabled optical large-baseline interferometry: applications, protocols and feasibility
Zixin Huang, Oleg Titov, Mikolaj K. Schmidt +4
Optical Very Long Baseline Interferometry (VLBI) offers the potential for unprecedented angular resolution in both astronomical imaging and precision measurements. Classical approa…
Parallactic delay for geodetic VLBI and non-orthogonality of the fundamental axes
Oleg Titov, Angelina Osetrova
The Gaia optical astrometric mission has measured the precise positions of millions of objects in the sky, including extragalactic sources also observed by Very Long Baseline Inter…
Serial MultiView: an efficient approach to mitigating atmospheric spatial-structure errors for VLBI astrometry
Jingdong Zhang, Bo Zhang, Shuangjing Xu +4
Atmospheric propagation errors are a main constraint on the accuracy of Very Long Baseline Interferometry (VLBI) astrometry. For relative astrometry, differential techniques can mi…
Resolving VLBI correlator ambiguity in the time delay model improves precision of geodetic measurements
Oleg Titov, Alexei Melnikov, Yulia Lopez
The modern Very Long Baseline Interferometry (VLBI) relativistic delay model, as documented in the IERS Conventions refers to the time epoch when the signal passes one of two stati…
On the nature of bright compact radio sources at z>4.5
Rocco Coppejans, Sándor Frey, Dávid Cseh +7
High-redshift radio-loud quasars are used to, among other things, test the predictions of cosmological models, set constraints on black hole growth in the early universe and unders…
The ICRF-3: Status, plans, and progress on the next generation International Celestial Reference Frame
Z. Malkin, C. S. Jacobs, F. Arias +17
The goal of this presentation is to report the latest progress in creation of the next generation of VLBI-based International Celestial Reference Frame, ICRF3. Two main directions…
Optical Spectra of Candidate Southern Hemisphere International Celestial Reference Frame (ICRF) radio sources
O. Titov, D. L. Jauncey, H. M. Johnston +2
We present the results of spectroscopic observations of the optical counterparts of 47 southern radio sources from the candidate International Celestial Reference Catalogue (ICRC),…
