AI Thread Summary
Calculating the inclination angle for galaxies in the Tully-Fischer relation requires knowledge of their major and minor axis dimensions. The user initially struggled with the geometrical relations needed for this calculation. They had the necessary data but were confused by the output format in Excel, which provided angles in radians. Ultimately, the issue was resolved as the user realized they had the correct approach all along. Accurate inclination angles are essential for understanding galaxy dynamics in the Tully-Fischer relation.

I've got a lab. And the deal is, you're measuring certain things on various galaxies and eventually calculating the Tully-Fischer relation. Anyways, part of it is calculating an inclination angle to all of the galaxies measured. And I'm stuck with this. I have the major and minor axis dimensions to each galaxy but not really much else. Have the magnitude of the flux through each of them, but don't think that would help. I'm somewhat bad at geometrical relations, can anyone help clue me in on getting inclination angles with just the dimensions of the galaxy and assuming that they're intrinsically circular systems and infinitely thin disks?

Nevermind, had it right beforehand. Excel just spits out angles in radians, got confused, hehe.
 
3I/ATLAS, also known as C/2025 N1 (ATLAS) and formerly designated as A11pl3Z, is an iinterstellar comet. It was discovered by the Asteroid Terrestrial-impact Last Alert System (ATLAS) station at Río Hurtado, Chile on 1 July 2025. Note: it was mentioned (as A11pl3Z) by DaveE in a new member's introductory thread. https://www.physicsforums.com/threads/brian-cox-lead-me-here.1081670/post-7274146 https://earthsky.org/space/new-interstellar-object-candidate-heading-toward-the-sun-a11pl3z/ One...
Is a homemade radio telescope realistic? There seems to be a confluence of multiple technologies that makes the situation better than when I was a wee lad: software-defined radio (SDR), the easy availability of satellite dishes, surveillance drives, and fast CPUs. Let's take a step back - it is trivial to see the sun in radio. An old analog TV, a set of "rabbit ears" antenna, and you're good to go. Point the antenna at the sun (i.e. the ears are perpendicular to it) and there is...
