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…
On Kinematic Substructure in the Sextans Dwarf Spheroidal Galaxy
Matthew G. Walker, Mario Mateo, Edward W. Olszewski +3
We present multifiber echelle radial velocity results for 551 stars in the Sextans dwarf spheroidal galaxy and identify 294 stars as probable Sextans members. The projected velocit…
The faint afterglow and host galaxy of the short-hard GRB 060121
A. J. Levan, N. R. Tanvir, A. S. Fruchter +14
We present optical and X-ray observations of the afterglow and host galaxy of the short-hard GRB 060121. The faint R-band afterglow is seen to decline as t^(-0.66) while the X-ray…
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…
