Astronomers can study how objects around the black hole, such as gas clouds and stars, are affected by its strong gravity…READ MORE

The Hydrogen Line V: Dark Matter

10 March 2014

In the last post we talked about using Newtons theory of gravity to calculate the mass of the Milky Way using the velocity of hydrogen clouds which we can measure with XRT-S. An example of this data from another similar project is shown below. This is called a rotation curve and plots the measured orbital…READ MORE
