The Parallax Zero-point of Gaia Early Data Release 3 from LAMOST Primary Red Clump Stars [PDF]

open access: yes, 2021
We present an independent examination of the parallax zero-point of the Third Gaia Early Data Release (hereafter EDR3), using the LAMOST primary red clump (PRC) stellar sample. A median parallax offset of around 26 μas, slightly larger than that found by

The Hawaii Infrared Parallax Program. IV. A Comprehensive Parallax Survey of L0–T8 Dwarfs with UKIRT [PDF]

open access: yesAstronomical Journal, 2020
We present parallaxes, proper motions, and J-band photometry for 348 L and T dwarfs measured using the wide-field near-infrared camera WFCAM on the United Kingdom Infrared Telescope.

Exploiting Motion Perception in Depth Estimation Through a Lightweight Convolutional Neural Network

open access: yesIEEE Access, 2021
Understanding the surrounding 3D scene is of the utmost importance for many robotic applications. The rapid evolution of machine learning techniques has enabled impressive results when depth is extracted from a single image.

Holographic Parallax Improves 3D Perceptual Realism [PDF]

open access: yesACM Transactions on Graphics
Holographic near-eye displays are a promising technology to solve long-standing challenges in virtual and augmented reality display systems. Over the last few years, many different computer-generated holography (CGH) algorithms have been proposed that ...

Distances and parallax bias in Gaia DR2 [PDF]

open access: yesMonthly notices of the Royal Astronomical Society, 2019
We derive Bayesian distances for all stars in the radial velocity sample of Gaia DR2, and use the statistical method of Schönrich, Binney & Asplund to validate the distances and test the Gaia parallaxes.

Parallax Theology: Reframing Compensation Theodicy

open access: yesReligions, 2023
The reality of suffering and the existence of natural and moral evils appear to present significant obstacles to the doctrine of God’s omnipotence, omniscience, and omnibenevolence. Theodicy is an attempt to resolve the problem of evil.

A CURRENT APPLICATION OF THE METHODS OF SECULAR AND STATISTICAL PARALLAX

open access: yesOdessa Astronomical Publications, 2012
The methods of secular and statistical parallax for homogeneous groups of Galactic stars are applied in a practical (classroom) exercise to establish the luminosity of bright B3 V stars. The solar motion of 20 km s-1 relative to group stars exceeds their

Narcissus and the Moon: Parallax in Early Modern Images

open access: yesSignata, 2021
This essay develops a comprehensive approach to the study of parallax effects in early modern images, with critical emphasis on painting. Parallax is the apparent displacement of an object relative to a given background, as caused by the movement of the ...

Confirmation of the Gaia DR2 Parallax Zero-point Offset Using Asteroseismology and Spectroscopy in the Kepler Field [PDF]

open access: yesAstrophysical Journal, 2018
We present an independent confirmation of the zero-point offset of Gaia Data Release 2 parallaxes using asteroseismic data of evolved stars in the Kepler field.

Parallax-Robust Surveillance Video Stitching

open access: yesSensors, 2015
This paper presents a parallax-robust video stitching technique for timely synchronized surveillance video. An efficient two-stage video stitching procedure is proposed in this paper to build wide Field-of-View (FOV) videos for surveillance applications.
