Suppression of the near-infrared OH night sky lines with fibre Bragg gratings - first results
S. C. Ellis, J. Bland-Hawthorn, J. Lawrence +20
The background noise between 1 and 1.8 microns in ground-based instruments is dominated by atmospheric emission from hydroxyl molecules. We have built and commissioned a new instru…
Search for a 33.9 MeV/c^2 Neutral Particle in Pion Decay
J. A. Formaggio, E. D. Zimmerman, T. Adams +41
The E815 (NuTeV) neutrino experiment has performed a search for a 33.9 MeV/c^2 weakly-interacting neutral particle produced in pion decay. Such a particle may be responsible for an…
Crystal plasticity finite element simulation of lattice rotation and x-ray diffraction during laser shock-compression of Tantalum
P. Avraam, D. McGonegle, P. G. Heighway +7
Wehrenberg et. al. [Nature 550 496 (2017)] used ultrafast in situ x-ray diffraction at the LCLS x-ray free-electron laser facility to measure large lattice rotations resulting from…
4MOST: Project overview and information for the First Call for Proposals
R. S. de Jong, O. Agertz, A. Agudo Berbel +335
We introduce the 4-metre Multi-Object Spectroscopic Telescope (4MOST), a new high-multiplex, wide-field spectroscopic survey facility under development for the four-metre-class Vis…
Sensitivity to the KARMEN Timing Anomaly at MiniBooNE
S. Case, S. Koutsoliotas, M. L. Novak
We present sensitivities for the MiniBooNE experiment to a rare exotic pion decay producing a massive particle, Q^0. This type of decay represents one possible explanation for the…
First demonstration of OH suppression in a high efficiency near-infrared spectrograph
S. C. Ellis, J. Bland-Hawthorn, J. S. Lawrence +21
Ground-based near-infrared astronomy is severely hampered by the forest of atmospheric emission lines resulting from the rovibrational decay of OH molecules in the upper atmosphere…
