Compression of space for low visibility probes [PDF]

open access: yesFrontiers in Systems Neuroscience, 2016
Stimuli briefly flashed just before a saccade are perceived closer to the saccade target, a phenomenon known as perisaccadic compression of space (Ross, Morrone, & Burr, 1997). More recently, we have demonstrated that brief probes are attracted towards a

SQUARE2: Spacecraft in QUAdrature for Solar Exploration—A Mission Concept for Synergetic Observations of the Sun and Heliosphere

open access: yesFrontiers in Astronomy and Space Sciences, 2022
SQUARE2 is the acronym for Spacecraft in QUAdrature for solaR Exploration, and is a mission concept for multi-instrumental two-point observations of the Sun and its environment. It stems from the need to have two probes that are systematically in orbital

Reflection from Inclined, Relativistic Light Sails

open access: yesThe Astronomical Journal, 2023
We present a new formula for relativistic reflection of solar radiation from a light sail moving at a velocity v inclined at an arbitrary angle θ , using an elementary two-body analysis. The formula is shown to reduce to the formulas of Euclid, Einstein,

Dust Outburst Dynamics and Hazard Assessment for Close Spacecraft–Comet Encounters

open access: yesThe Planetary Science Journal, 2021
Using the gas drag by sublimating cometary surface ices for the acceleration of dust particles and deceleration by the gravity field of the nucleus combined with basic laws of mechanics, the sizes, velocities, and number densities of escaping particles ...

Applicability of Taylor's hypothesis in thermally driven turbulence [PDF]

open access: yesRoyal Society Open Science, 2018
In this paper, we show that, in the presence of large-scale circulation (LSC), Taylor’s hypothesis can be invoked to deduce the energy spectrum in thermal convection using real-space probes, a popular experimental tool. We perform numerical simulation of

Black holes as probes of moduli space geometry

open access: yesJournal of High Energy Physics, 2023
We argue that supersymmetric BPS states can act as efficient finite energy probes of the moduli space geometry thanks to the attractor mechanism. We focus on 4d N $$ \mathcal{N} $$ = 2 compactifications and capture aspects of the effective field theory ...

Surviving in Ocean Worlds: Experimental Characterization of Fiber Optic Tethers across Europa-like Ice Faults and Unraveling the Sliding Behavior of Ice

open access: yesThe Planetary Science Journal, 2023
As an initial step toward in situ exploration of the interiors of Ocean Worlds to search for life using cryobot architectures, we test how various communication tethers behave under potential Europa-like stress conditions.

Probing Olfaction in Space and Time [PDF]

open access: yesNeuron, 2020
In this issue, Gill et al. apply holographic optogenetic stimulation in the olfactory bulb to control select neuronal ensembles in 3D. This approach allows them to dissociate the contribution of temporal spike features and spike rate to stimulus detection.
