• #### Object-based attention with endogenous cuing and positional certainty ﻿

(University of Canterbury. Psychology., 2008)
Previous studies have concluded that object-based attention does not always arise if attention is cued endogenously (Macquistan, 1997) or if the target location is known with certainty (Shomstein & Yantis, 2002). In the ...
• #### An object-based cost of visual filtering ﻿

(University of Canterbury. Psychology., 2000)
Although evidence for object-based attention has been reported in a variety of paradigms, few studies have examined directly the relationship between the processing efficiency of the targets and the number of ...
• #### Observational challenges for the standard FLRW model ﻿

(University of Canterbury. Physics and Astronomy, 2016)
We summarise some of the main observational challenges for the standard Friedmann– Lemaˆıtre–Robertson–Walker cosmological model and describe how results recently presented in the parallel session “Large–scale Structure ...
• #### Occurrence of a novel mastrevirus in sugarcane germplasm collections in Florida, Guadeloupe and Réunion ﻿

© 2017 The Author(s). Background: In Africa and Asia, sugarcane is the host of at least seven different virus species in the genus Mastrevirus of the family Geminiviridae. However, with the exception of Sugarcane white ...
• #### Octasubstituted biphenylenes: is there a favoured conformation? ﻿

(University of Canterbury. Chemistry., 2007)
Octakis(pyrazol-1-ylmethyl)biphenylene ethanol solvate, C₄₄H₄₀N₁₆C₂H₆O, has two independent centrosymmetric molecules, one of which is hydrogen bonded to the solvent molecule. One molecule adopts an arrangement with three ...
• #### OGLE-2005-BLG-071Lb, the Most Massive M Dwarf Planetary Companion? ﻿

(University of Canterbury. Physics and Astronomy, 2009)
We combine all available information to constrain the nature of OGLE-2005-BLG-071Lb, the second planet discovered by microlensing and the first in a high-magnification event. These include photometric and astrometric ...
• #### OGLE-2011-BLG-0265Lb: A Jovian Microlensing Planet Orbiting an M Dwarf ﻿

(University of Canterbury. Physics and Astronomy, 2015)
We report the discovery of a Jupiter-mass planet orbiting an M-dwarf star that gave rise to the microlensing event OGLE-2011-BLG-0265. Such a system is very rare among known planetary systems and thus the discovery is ...
• #### OGLE-2015-BLG-1459L: The Challenges of Exo-Moon Microlensing ﻿

(2017)
We show that dense OGLE and KMTNet $I$-band survey data require four bodies (sources plus lenses) to explain the microlensing light curve of OGLE-2015-BLG-1459. However, these can equally well consist of three lenses ...
• #### OGLE-2016-BLG-0168 Binary Microlensing Event: Prediction and Confirmation of the Microlens Parallax Effect from Space-based Observations ﻿

(2017)
© 2017. The American Astronomical Society. All rights reserved.. The microlens parallax is a crucial observable for conclusively identifying the nature of lens systems in microlensing events containing or composed of faint ...
• #### OGLE-2016-BLG-0263Lb: Microlensing Detection of a Very Low-mass Binary Companion through a Repeating Event Channel ﻿

(2017)
© 2017. The American Astronomical Society. All rights reserved. We report the discovery of a planet-mass companion to the microlens OGLE-2016-BLG-0263L. Unlike most lowmass companions that were detected through perturbations ...
• #### OGLE-2016-BLG-0613LABb: A Microlensing Planet in a Binary System ﻿

(2017)
© 2017. The American Astronomical Society. All rights reserved.. We present the analysis of OGLE-2016-BLG-0613, for which the lensing light curve appears to be that of a typical binary-lens event with two caustic spikes ...

(2017)
We report the analysis of the first resolved caustic-crossing binary-source microlensing event OGLE-2016-BLG-1003. The event is densely covered by the round-the-clock observations of three surveys. The light curve is ...
• #### OGLE-2016-BLG-1045: A Test of Cheap Space-Based Microlens Parallaxes ﻿

(2018)
Microlensing is a powerful and unique technique to probe isolated objects in the Galaxy. To study the characteristics of these interesting objects based on the microlensing method, measurement of the microlens parallax ...
