Addendum: "Hubble Space Telescope Evidence for an Intermediate-Mass Black Hole in the Globular Cluster M15: II. Kinematical Analysis and Dynamical Modeling"
Joris Gerssen,Roeland P. van der Marel,Karl Gebhardt,Puragra Guhathakurta,Ruth C. Peterson,Carlton Pryor +5 more
TL;DR: In this article, it was shown that there is an error in the figure in Dull et al. (1997, D97) that shows the radial M/L profile in Fokker-Planck models of M15.

Hubble Space Telescope Observations of NGC 6240: a Case Study of an Ultra-Luminous Infrared Galaxy with Obscured Activity
Joris Gerssen,Roeland P. van der Marel,David J. Axon,J. Christopher Mihos,Lars Hernquist,Joshua E. Barnes +5 more
TL;DR: In this article, the authors present results from an HST study of the morphology and kinematics of NGC 6240, a merging galaxy with a double nucleus, which is one of the nearest and best-studied ultraluminous infrared galaxies.
Model independent measurements of bar pattern speeds

- 01 Dec 2002
TL;DR: In this paper, the authors present the results of model-independent measurements of the bar pattern speed in four galaxies ranging in Hubble type from SB0 to SBBC, and three of the four galaxies in their sample are consistent with bars being fast rotators.

Hubble Space Telescope Evidence for an Intermediate-Mass Black Hole in the Globular Cluster M15: I. STIS Spectroscopy and WFPC2 Photometry
Roeland P. van der Marel,Joris Gerssen,Puragra Guhathakurta,Puragra Guhathakurta,Ruth C. Peterson,Karl Gebhardt +5 more
TL;DR: In this article, the authors describe a project with STIS on HST to measure the line-of-sight velocities of stars in the central few arcsec of the dense globular cluster M15.

GMOS IFU observations of the stellar and gaseous kinematics in the centre of NGC 1068
TL;DR: In this paper, an atlas of velocity components derived from multiple Gaussian component fits to the emission lines is presented, which cannot be readily associated with distinct physical structures and are suggestive of high velocity flows or disk-like structures.
