A Demonstration of Interstellar Navigation Using New Horizons
Tod R. Lauer, David H. Munro, John R. Spencer +51
As NASA's New Horizons spacecraft exits the Solar System bound for interstellar space, it has traveled so far that the nearest stars have shifted markedly from their positions seen…
Detection of a Radio Bubble around the Ultraluminous X-ray Source Holmberg IX X-1
Ciprian T. Berghea, Megan C. Johnson, Nathan J. Secrest +3
We present C and X-band radio observations of the famous utraluminous X-ray source (ULX) Holmberg IX X-1, previously discovered to be associated with an optical emission line nebul…
A Global Astrometric Solution for Pan-STARRS referenced to ICRF2
C. T. Berghea, V. V. Makarov, J. Frouard +13
We describe development and application of a Global Astrometric Solution (GAS) to the problem of Pan-STARRS1 (PS1) astrometry. Current PS1 astrometry is based on differential astro…
Correlated and zonal errors of global astrometric missions: a spherical harmonic solution
V. V. Makarov, B. N. Dorland, R. A. Gaume +4
We propose a computer-efficient and accurate method of estimation of spatially correlated errors in astrometric positions, parallaxes and proper motions obtained by space and groun…
The Worst Distortions of Astrometric Instruments and Orthonormal Models for Rectangular Fields of View
Valeri V. Makarov, Daniel R. Veillette, Gregory S. Hennessy +1
The non-orthogonality of algebraic polynomials of field coordinates traditionally used to model field-dependent corrections to astrometric measurements, gives rise to subtle advers…
Photometric observations of selected, optically bright quasars for Space Interferometry Mission and other future celestial reference frames
Roopesh Ojha, Norbert Zacharias, Gregory S. Hennessey +2
Photometric observations of 235 extragalactic objects that are potential targets for the Space Interferometry Mission (SIM) are presented. Mean B, V, R, I magnitudes at the 5% leve…
