The James Webb Space Telescope Mission

Jonathan P. Gardner, John C. Mather, Randy Abbott +1004

Twenty-six years ago a small committee report, building on earlier studies, expounded a compelling and poetic vision for the future of astronomy, calling for an infrared-optimized…

A Stellar Dynamical Measurement of the Black Hole Mass in the Maser Galaxy NGC 4258

Christos Siopis, Karl Gebhardt, Tod R. Lauer +13

We determine the mass of the black hole at the center of the spiral galaxy NGC 4258 by constructing axisymmetric dynamical models of the galaxy. These models are constrained by hig…

The Black Hole Mass and Extreme Orbital Structure in NGC1399

Karl Gebhardt, Tod R. Lauer, Jason Pinkney +12

The largest galaxies, and in particular central galaxies in clusters, offer unique insight into understanding the mechanism for the growth of nuclear black holes. We present Hubble…

The Black Hole Mass of NGC 4151: Comparison of Reverberation Mapping and Stellar Dynamical Measurements

Christopher A. Onken, Monica Valluri, Bradley M. Peterson +11

We present a stellar dynamical estimate of the black hole (BH) mass in the Seyfert 1 galaxy, NGC 4151. We analyze ground-based spectroscopy as well as imaging data from the ground…

HST STIS spectroscopy of the triple nucleus of M31: two nested disks in Keplerian rotation around a Supermassive Black Hole

Ralf Bender, John Kormendy, Gary Bower +12

We present HST spectroscopy of the nucleus of M31 obtained with STIS. Spectra taken around the CaT lines at 8500 see only the red giants in the double bright- ness peaks P1 and P2.…
