Evaluating the Alignment of the Polarized Starlight from 893 Stars in a Region on the Disk of the Milky Way

Detecting polarized starlight projects an intriguing pattern of polarization directions on the Galaxy. Polarized starlight is a well known tracer of Galactic Magnetic fields and is a tool for studying the dust that contaminates the view of more distant objects. The alignment of the polarization directions of a sample of stars on the Galactic Disk is investigated with a recently devised test. The Hub Test offers numerical metrics based on the geometry of spherical geodesics, i.e. great circles, to judge alignment. The test always compares the directions of two vectors at a single point, a process that avoids comparing the directions of two vectors at distinct points; no parallel transport needed. The sample of 893 stars, located from longitude 90° to 160° and latitude -15° to +15°, is among the best aligned regions on the Disk. The alignment function provides a full-sphere depiction of the collective alignment. The metrics include the likelihood that random polarization directions would produce equal or better alignments. For the 893 star sample considered here, the alignment occurs at the 54sigma level. The alignment function has minima along an equator, which, for this sample, coincides with the Galactic Disk, and the function has maxima at poles, here coincident with the Galactic Poles. The source of the polarization data is the Heiles 2000 agglomeration catalog. This article is a Mathematica notebook which can be accessed and run via a link in the References.

"Зеркало" Вселенной ("Mirror" of the Universe)

автор ездил в Москву в МГУ на семинар биофизика А. П. Левича (по его приглашению). К сожалению, обзорный доклад автора (есть в интернете) не мог включать довольно «тонкие» и весьма любопытные вопросы мира чисел, которые содержатся в книге «Зеркало» Вселенной». Например, там (в гл. 10) впервые говорится про удивительные метачисла (но сам этот термин появился только в апреле 2020 г., когда автор открыл формулу для вычисления любого метачисла).

the author traveled to Moscow at Moscow State University for a seminar by biophysicist A.P. Levich (at his invitation). Unfortunately, the author's survey report (available on the Internet) could not include rather "subtle" and very curious questions of the world of numbers, which are contained in the book "Mirror" of the Universe ". For example, there (in Chapter 10), for the first time, it is said about amazing meta numbers (but this term itself appeared only in April 2020, when the author discovered a formula for calculating any meta number).
