The coherent image distortions induced by weak gravitational lens-ing can be used to measure the power spectrum of density inhomogeneities in the universe. We present our ongoing effort to detect this effect with the FIRST radio survey, which currently contains about 400,000 sources over 4,200 square degrees, and thus provides a unique resource for this purpose. We discuss the sensitivity of ou...

We present the results of our (the LUNASKA project’s) initial search for pulses of coherent radio Cherenkov radiation from UHE neutrino and cosmic ray interactions in the outer layers of the Moon. Three of the six 22 m antennas of the Australia Telescope Compact Array (ATCA) were implemented with our purpose-built pulse detection hardware and used to observe the Moon for two three-night periods...

This contribution describes the experimental set-up implemented by the LUNASKA project at the Australia Telescope Compact Array (ATCA) to enable the radio-telescope to be used to search for pulses of coherent Cherenkov radiation from UHE particle interactions in the Moon with an unprecedented bandwidth, and hence sensitivity. Our specialised hardware included analogue dedispersion filters to co...

Neutrinos interact with hadronic and leptonic matter only through weak processes having very low cross-sections. To detect neutrinos with a primary energy below 1 PeV, most efforts have relied on the use of photo multiplier (PM) tubes and detection of visible Vavilov-Čerenkov light. Above 1 PeV, the use of embedded optical detectors becomes unfeasible. Ideas on how to increase the detection vol...

Currently, spatial signal processing for adaptive source separation and interference cancellation are extensively discussed for application in future mobile radio systems. ESPRIT-type algorithms are especially concerned because of their low arithmetic complexity and their inherent ability for superresolution estimation of the direction of arrival (DoA) [1]. The latter is also true for mobile ra...

Context. The Crab pulsar emits across a large part of the electromagnetic spectrum. Determining the time delay between the emission at different wavelengths will allow to better constrain the site and mechanism of the emission.We have simultaneously observed the Crab Pulsar in the optical with S-Cam, an instrument based on Superconducting Tunneling Junctions (STJs) with μs time resolution and a...

Ambient backscatter communication (AmBC) leverages the existing ambient radio frequency (RF) environment to implement with battery-free devices. The key challenge in development of AmBC is very weak RF signals backscattered by Tag. To overcome this challenge, we propose use orthogonal space-time block codes (OSTBC) incorporating multiple antennas at Tag as well Reader. Our approach considers bo...

an association between coeliac disease and fertility disorders is well recognised in the current literature, but the information related to non-coeliac gluten sensitivity (ncgs) and infertility is lacking. this case highlights a possible role of treating ncgs in the reversal of infertility.
