Proper Motion of the Leo II Dwarf Galaxy Based On Hubble Space Telescope Imaging
Slawomir Piatek, Carlton Pryor, Edward W. Olszewski
This article reports a measurement of the proper motion of Leo II, a dwarf galaxy that is a likely satellite of the Milky Way, based on imaging with the Hubble Space Telescope and…
Proper Motion of the Draco Dwarf Galaxy Based On Hubble Space Telescope Imaging
Carlton Pryor, Slawomir Piatek, Edward W. Olszewski
We have measured the proper motion of the Draco dwarf galaxy using images at two epochs with a time baseline of about two years taken with the Hubble Space Telescope and the Advanc…
The Star Formation History and Extended Structure of the Hercules Milky Way Satellite
D. J. Sand, E. W. Olszewski, B. Willman +5
We present imaging of the recently discovered Hercules Milky Way satellite and its surrounding regions to study its structure, star formation history and to thoroughly search for s…
Proper Motions of the LMC and SMC: Reanalysis of Hubble Space Telescope Data
S. Piatek, C. Pryor, E. W. Olszewski
Kallivayalil et al. have used the \textit{Hubble Space Telescope} to measure proper motions of the LMC and SMC using images in 21 and five fields, respectively, all centered on kno…
Proper Motions of Dwarf Spheroidal Galaxies from Hubble Space Telescope Imaging. V: Final Measurement for Fornax
Slawomir Piatek, Carlton Pryor, Paul Bristow +5
The measured proper motion of Fornax, expressed in the equatorial coordinate system, is mas century. This proper motion is a weighted…
A Fundamental Relation Between Compact Stellar Nuclei, Supermassive Black Holes, and Their Host Galaxies
Laura Ferrarese, Patrick Cote, Elena Dalla Bonta +9
Imaging surveys with the Hubble Space Telescope (HST) have shown that roughly 50-80% of low- and intermediate-luminosity galaxies contain a compact stellar nucleus at their center,…
