HST astrometry: the Galactic constant Theta_0/R_0
L. R. Bedin, G. Piotto, I. R. King +1
From multi-epoch WFPC2/HST observations we present astrometric measurements of the absolute motion of the bulge stars. The presence of an extragalactic point-source candidate allow…
Chandra observations of PSR B1509-58 and Supernova Remnant G320.4-1.2
B. M. Gaensler, J. Arons, M. J. Pivovaroff +1
The young and energetic pulsar B1509-58 powers a bright X-ray synchrotron nebula, embedded in the unusual supernova remnant G320.4-1.2. We present observations of this system with…
Hands-On Universe: A Global Program for Education and Public Outreach in Astronomy
M. Boer, H. Pack, C. Pennypacker +3
Hands-On Universe (HOU) is an educational program that enables students to investigate the Universe while applying tools and concepts from science, math, and technology. Using the…
Hands-On TAROT: Intercontinental use of the TAROT for Education and Public Outreach
M. Boer, C. Thiebaut, A. Klotz +4
The TAROT telescope has for primary goal the search for the prompt optical counterpart of Cosmic Gamma-Ray Bursts. It is a completely autonomous 25cm telescope installed near Nice…
EUVE Observations of clusters of galaxies: Virgo and M87
Thomas W. Berghoefer, Stuart Bowyer, Eric Korpela
We present results of a re-analysis of archival EUVE data of the central region of the Virgo cluster. We employ the new analysis method developed by Bowyer, Berghöfer & Korpela (19…
Application of SFD Dust Maps to Galaxy Counts and CMB Experiments
D. J. Schlegel, D. P. Finkbeiner, M. Davis
We have constructed a full-sky map of the far-infrared suitable for measuring Galactic reddening and extinction (Schlegel, Finkbeiner & Davis 1998: SFD). The SFD map is based upon…
