Here are two recent papers related to developments in black hole science:

1. **Black Holes with Skyrme Hair**
   - Authors: Noriko Shiiki, Nobuyuki Sawado
   - Published: 2005-01-09
   - Summary: This paper reviews developments in the field of black holes with Skyrme hair. The Einstein-Skyrme system has been shown to possess black hole solutions with Skyrme hair, countering the no-hair conjecture for black holes. The study details the properties of B=1 and B=2 skyrmions, extension to monopole black hole skyrmions, and stable solutions with balanced gravitational, electromagnetic, and strong forces.

2. **Galaxy bulges and their massive black holes: a review**
   - Author: Alister W. Graham
   - Published: 2015-01-13
   - Summary: This article reviews the historical development of the understanding of massive black holes at galactic centers, the evolution of their mass relations, and observed sub-structure in black hole-velocity dispersion diagrams. It focuses on the fundamental connections between massive black holes and their host galaxies, reviewing various scaling relations.
