A posteriori correction of Gaia CRF proper motions using conditional probability and zero-parallax prior
Valeri V. Makarov
Precision of proper motions and positions given in the Gaia Celestial Reference Frame (CRF) catalog can be statistically improved introducing conditional probability based on the p…
Gaia parallax bias via spherical harmonics: A Python tool and discussion of possible causes
Valeri V. Makarov, Ciprian T. Berghea
Parallaxes in Gaia DR3 are known to suffer from a complex set of sky-correlated and magnitude-dependent offsets or biases at the level of a few tens of as. Estimated from a samp…
Systematic Effects in Gaia CRF Photometry Related to Scanning Geometry and BP/RP excess factor
Valeri V. Makarov
I report a previously undocumented, large-amplitude systematic dependence of the median Gaia -band magnitude of CRF3 sources on \texttt{ra\_dec\_corr}, which reflects the prefer…
Mapping the Universe as a Bianchi I cosmology with Gaia data
Valeri V. Makarov, Asta Heinesen, Thomas Schücker
Measurements of tangential drifts of distant quasars and galactic nuclei on the celestial sphere provide a novel and independent method of testing cosmological hypotheses. In this…
The Peculiar Velocity of Messier~87 from Microarcsecond Geodetic VLBI Astrometry
Valeri V. Makarov, Phil Cigan, Kyle Corcoran
Our knowledge of the space velocity of Messier 87, which is the dominant galaxy in the Virgo cluster, has been limited to the radial velocity component. Using a cadence of precisio…
Distributions of wide binary stars in theory and in Gaia data: III. Orbital momenta, masses, and manifestations of MOND
Valeri V. Makarov
Using the censored catalog of 103,169 resolved Gaia DR3 binary stars with accurate astrometric data for each component, a new observable, object-specific parameter is computed for…
