A Sliding Blocks Estimator for the Extremal Index
Christian Y. Robert, Johan Segers, Christopher A. T. Ferro
In extreme value statistics for stationary sequences, blocks estimators are usually constructed by using disjoint blocks because exceedances over high thresholds of different block…
Direct Imaging of Multiple Planets Orbiting the Star HR 8799
C. Marois, B. Macintosh, T. Barman +5
Direct imaging of exoplanetary systems is a powerful technique that can reveal Jupiter-like planets in wide orbits, can enable detailed characterization of planetary atmospheres, a…
The 2dF-SDSS LRG and QSO Survey: The spectroscopic QSO catalogue
Scott M. Croom, Gordon T. Richards, Tom Shanks +27
We present the final spectroscopic QSO catalogue from the 2dF-SDSS LRG and QSO (2SLAQ) Survey. This is a deep, 18<g<21.85 (extinction corrected), sample aimed at probing in detail…
Superlattice properties of semiconductor nanohelices in a transverse electric field
O. V. Kibis, M. E. Portnoi
A charge carrier confined in a quasi-one-dimensional semiconductor helical nanostructure in the presence of an electric field normal to the axis of the helix is subjected to a peri…
Exciton storage in a nano-scale Aharonov-Bohm ring with electric field tuning
Andrea M. Fischer, Vivaldo L. Campo, Mikhail E. Portnoi +1
We study analytically the optical properties of a simple model for an electron-hole pair on a ring subjected to perpendicular magnetic flux and in-plane electric field. We show how…
The Lagoon Nebula and its Vicinity
N. F. H. Tothill, Marc Gagné, B. Stecklum +1
The Lagoon Nebula is an HII region in the Sagittarius Arm, about 1.3 kpc away, associated with the young (1-3 Myr) open cluster NGC 6530, which contains several O stars and several…
