    Data Orbit Star
AI Thread Summary
Data on the orbit of the S2 star around the black hole Sgr-A is sought for a project aimed at proving black hole existence. A specific paper is recommended, which contains the orbital elements of 28 stars, including S2. The paper can be accessed via the provided link to arXiv. Participants are encouraged to explore this resource for their calculations. This information is crucial for research on stellar orbits in the vicinity of black holes.

Hello,
I'm doing a project on proving the existence of black holes. I am using Sgr-A as a test subject and am after the data set for the orbit of the star S2 around it so I can do some of my own calculations on it. Does anyone know where i might be able to obtain these?

Thread 'Does it make sense to build new radio telescopes?'

TL;DR Summary: In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation. In case of failure to detect alien signals, it will further expand the radius of the so-called silence (or rather, radio silence) of the Universe. Is there any sense in this or is blissful ignorance better? In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation.

Thread 'Could gamma-ray bursts have an intragalactic origin?'

Thread 'Could gamma-ray bursts have an intragalactic origin?'

This is indirectly evidenced by a map of the distribution of gamma-ray bursts in the night sky, made in the form of an elongated globe. And also the weakening of gamma radiation by the disk and the center of the Milky Way, which leads to anisotropy in the possibilities of observing gamma-ray bursts. My line of reasoning is as follows: 1. Gamma radiation should be absorbed to some extent by dust and other components of the interstellar medium. As a result, with an extragalactic origin, fewer...
