Submillimetre Cosmology at High Angular Resolution [PDF]

EAS Publications Series, 2009
Over the last decade observations at submillimetre (submm) and millimetre (mm) wavelengths, with their unique ability to trace molecular gas and dust, have attained a central role in our exploration of galaxies at all redshifts.

Prototype high angular resolution LEKIDs for NIKA2 [PDF]

Journal of Low Temperature Physics, 2018
The current resolution of the NIKA2 260 GHz arrays is limited by the $1.6\times 1.5 mm^2$ inductor size on the individual pixels. In view of future updates of the instrument, we have developed a prototype array with smaller pixels that is experimentally ...

The High Angular Resolution Multiplicity of Massive Stars [PDF]

The Astronomical Journal, 2008
We present the results of a speckle interferometric survey of Galactic massive stars that complements and expands upon a similar survey made over a decade ago.

TNO, occultation, and high angular resolution astronomy [PDF]

EPJ Web of Conferences, 2011
The trans-Neptunian region is a new frontier in the solar system research. Occultation is currently the only way to detect a trans-Neptunian object (TNO) of typical comet-size in that region.

Fast diffusion imaging with high angular resolution. [PDF]

Magn Reson Med, 2017
PurposeHigh angular resolution diffusion imaging (HARDI) is a well‐established method to help reveal the architecture of nerve bundles, but long scan times and geometric distortions inherent to echo planar imaging (EPI) have limited its integration into clinical protocols.MethodsA fast imaging method is proposed here that combines accelerated multishot

High-angular-resolution interferometric backscatter meter

Optics Letters, 2022
Backscatter limits many interferometric measurements, including gravitational wave detectors, by creating spurious interference. We describe an experimental method to directly and quantitatively measure the backscatter interference. We derive and verify experimentally a relation between backscatter interference, beam radius, and the scattering sample ...

High-angular resolution diffusion tensor imaging: physical foundation and geometric framework

Frontiers in Physics
This paper proposes a statistical physics-based data assimilation model for the mobility of water-bound hydrogen nuclear spins in the brain in the context of diffusion weighted magnetic resonance imaging (DWI or DW-MRI).

The AT20G high-angular-resolution catalogue [PDF]

Monthly Notices of the Royal Astronomical Society, 2013
We present the high angular resolution catalogue for the Australia Telescope 20 GHz (AT20G) survey, using the high angular resolution 6-km antenna data at the baselines of ~ 4500 m of the Australia Telescope Compact Array (ATCA). We have used the data to produce the visibility catalogue that separates the compact Active Galactic Nuclei (AGNs) from the ...

High angular resolution gravitational wave astronomy [PDF]

Experimental Astronomy, 2021
AbstractSince the very beginning of astronomy the location of objects on the sky has been a fundamental observational quantity that has been taken for granted. While precise two dimensional positional information is easy to obtain for observations in the electromagnetic spectrum, the positional accuracy of current and near future gravitational wave ...

gyre_tides: Modeling Binary Tides within the GYRE Stellar Oscillation Code

The Astrophysical Journal, 2023
We describe new functionality in the GYRE stellar oscillation code for modeling tides in binary systems. Using a multipolar expansion in space and a Fourier-series expansion in time, we decompose the tidal potential into a superposition of partial tidal ...
