Jets, Disks and Winds from Spinning Black Holes: Nature or Nurture?
Galaxies, 2022 A brief summary is given of an alternative interpretation of the Event Horizon Telescope observations of the massive black hole in the nucleus of the nearby galaxy M87. It is proposed that the flow is primarily powered by the black hole rotation, not the

Astronomy in the City for Astronomy Education [PDF]
Proceedings of the International Astronomical Union, 2015 AbstractAstronomy is part of our culture. Astronomy cannot be isolated in a classroom, it has to be integrated in the normal life of teachers and students. “Astronomy in the city” is an important part of NASE (Network for Astronomy School Education) (Ros & Hemenway 2012). In each NASE course we introduce a “working group session” chaired by a local

Dark Energy in Light of Multi-Messenger Gravitational-Wave Astronomy [PDF]
Frontiers in Astronomy and Space Sciences, 2018 Gravitational waves (GWs) provide a new tool to probe the nature of dark energy (DE) and the fundamental properties of gravity. We review the different ways in which GWs can be used to test gravity and models for late-time cosmic acceleration. Lagrangian-
