Final results from the Palo Verde Neutrino Oscillation Experiment
F. Boehm, J. Busenitz, B. Cook +14
The analysis and results are presented from the complete data set recorded at Palo Verde between September 1998 and July 2000. In the experiment, the $\nuebar$ interaction rate has…
EWOCS-IV: 1Ms ACIS Chandra observation of the supergiant B[e] star Wd1-9
K. Anastasopoulou, M. G. Guarcello, J. J. Drake +21
Supergiant B[e] (sgB[e]) stars are exceptionally rare objects, with only a handful of confirmed examples in the Milky Way. The evolutionary pathways leading to the sgB[e] phase rem…
Search for Neutrino Oscillations at the Palo Verde Nuclear Reactors
F. Boehm, J. Busenitz, B. Cook +14
We report on the initial results from a measurement of the anti-neutrino flux and spectrum at a distance of about 800 m from the three reactors of the Palo Verde Nuclear Generating…
A New Measurement of the Radiative Decay Width
I. Larin, D. McNulty, E. Clinton +70
High precision measurements of the differential cross sections for photoproduction at forward angles for two nuclei, C and Pb, have been performed for inciden…
Results from the Palo Verde Neutrino Oscillation Experiment
F. Boehm, J. Busenitz, B. Cook +14
The $\nuebar$ flux and spectrum have been measured at a distance of about 800 m from the reactors of the Palo Verde Nuclear Generating Station using a segmented Gd-loaded liquid sc…
Nuclear Targets for a Precision Measurement of the Neutral Pion Radiative Width
P. Martel, E. Clinton, R. McWilliams +60
A technique is presented for precision measurements of the area densities, density * T, of approximately 5% radiation length carbon and 208Pb targets used in an experiment at Jeffe…
EWOCS-I: The catalog of X-ray sources in Westerlund 1 from the Extended Westerlund 1 and 2 Open Clusters Survey
M. G. Guarcello, E. Flaccomio, J. F. Albacete-Colombo +48
Context. With a mass exceeding several 10^4 solar masses and a rich and dense population of massive stars, supermassive young star clusters represent the most massive star-forming…
An initial study of mesons and baryons containing strange quarks with GlueX
The GlueX Collaboration, A. AlekSejevs, S. Barkanova +97
The primary motivation of the GlueX experiment is to search for and ultimately study the pattern of gluonic excitations in the meson spectrum produced in collisions. Recent l…
EWOCS-III: JWST observations of the supermassive star cluster Westerlund 1
M. G. Guarcello, V. Almendros-Abad, J. B. Lovell +29
The typically large distances, extinction, and crowding of Galactic supermassive star clusters have so far hampered the identification of their very low mass members, required to e…
A study of decays to strange final states with GlueX in Hall D using components of the BaBar DIRC
The GlueX Collaboration, M. Dugger, B. Ritchie +103
We propose to enhance the kaon identification capabilities of the GlueX detector by constructing an FDIRC (Focusing Detection of Internally Reflected Cherenkov) detector utilizing…
Measurement of single- and double-polarization observables in the photoproduction of ~meson pairs off the proton using CLAS at Jefferson Laboratory
P. Roy, S. Cao, V. Crede +141
The photoproduction of meson pairs off the proton has been studied in the reaction using the CEBAF Large Acceptance Spectrometer (CLAS) and the froz…
EWOCS-II: X-ray properties of the Wolf-Rayet stars in the young Galactic super star cluster Westerlund 1
K. Anastasopoulou, M. G. Guarcello, E. Flaccomio +20

First spectroscopic identification of the main sequence in Westerlund 1
R. Castellanos, F. Najarro, M. Garcia +8
Being the most massive known young stellar cluster in the Milky Way, Westerlund 1 (Wd1) constitutes an ideal benchmark for understanding the evolution of massive stars. However, th…
Investigating the properties of Galactic Luminous Blue Variables via IR observations
J. S. Clark, A. Arkharov, V. Larionov +3
Recent IR surveys of the Galactic plane have revealed a large number of candidate Luminous Blue Variables. In order to verify these classifications we have been undertaking a long…
