The Seyfert 1 galaxy, Ark 120, is a prototype example of the so-called class of bare nucleus AGN, whereby there is no known evidence for the presence of ionized gas along the direct line of sight. Here deep ($>400$ ks exposure), high resolution X-ray... Read More about A deep X-ray view of the bare AGN Ark 120. I. Revealing the Soft X-ray Line Emission.

Do open star clusters evolve toward energy equipartition? (2016)
Journal Article
(2016). Do open star clusters evolve toward energy equipartition?. Monthly Notices of the Royal Astronomical Society, 317-328. https://doi.org/10.1093/mnras/stw998

We investigate whether open clusters (OCs) tend to energy equipartition, by means of direct N-body simulations with a broken power-law mass function. We find that the simulated OCs become strongly mass segregated, but the local velocity dispersion do... Read More about Do open star clusters evolve toward energy equipartition?.

Mass segregation in star clusters is often thought to indicate the onset of energy equipartition, where the most massive stars impart kinetic energy to the lower-mass stars and brown dwarfs/free floating planets. The predicted net result of this is t... Read More about Mass segregation in star clusters is not energy equipartition.
