Can exoplanetary systems remain intact in dense stellar environments, or are their exoplanets destined to be flung into the far reaches of space? N-body simulations hint at characteristics that lead to a higher likelihood of survival.
It’s difficult to tell how the individual stars of a galaxy rotate. What can we find out just from their metal content?
High resolution images from New Horizons of the surfaces of Pluto and Charon show ancient craters, but fewer than astronomers expected.
Today’s post presents SIMBA, a cosmological simulation that focuses on understanding the growth and evolution of black holes and their host galaxy.
Observations of dim galaxies lensed by foreground clusters provides a way of measuring the progression of reionization.
Today’s post looks at the investigation of a very small galaxy hosting a black hole that’s 15% of its total mass. This paper investigates whether this was once a much bigger galaxy, but has been robbed of its stars by a close call with another nearby galaxy.
