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,…
The ACS Virgo Cluster Survey. VI. Isophotal Analysis and the Structure of Early-Type Galaxies
Laura Ferrarese, Patrick Cote, Andres Jordan +8
(Abridged) We present a detailed analysis of the morphology, isophotal parameters and surface brightness profiles for 100 early-type members of the Virgo Cluster, from dwarfs (M_B…
Proper Motions of Dwarf Spheroidal Galaxies from Hubble Space Telescope Imaging. IV: Measurement for Sculptor
S. Piatek, C. Pryor, P. Bristow +5
This article presents a measurement of the proper motion of the Sculptor dwarf spheroidal galaxy determined from images taken with the Hubble Space Telescope using the Space Telesc…
Proper Motions of Dwarf Spheroidal Galaxies from Hubble Space Telescope Imaging. III: Measurement for Ursa Minor
S. Piatek, C. Pryor, P. Bristow +5
This article presents a measurement of the proper motion of the Ursa Minor dwarf spheroidal galaxy determined from images taken with the Hubble Space Telescope in two distinct fiel…
