Results of LUNASKA lunar Cherenkov observations at the ATCA

چکیده
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 during 2008. The observation dates and beam pointing position were chosen to maximise sensitivity to Centaurus A and the Galactic Centre (nominally Sgr A) region. We present the results of our (now complete) data analysis of order 10 candidate events – though we find no evidence for lunar Cherenkov pulses, our use of a wide (600 MHz) bandwidth has made our observations the most sensitive yet using the lunar technique.

Experimental set - up of the LUNASKA lunar Cherenkov observations at the ATCA
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...
متن کاملThe Directional Dependence of the Lunar Cherenkov Technique for UHE Neutrino Detection
The LUNASKA (Lunar UHE Neutrino Astrophysics with the Square Kilometre Array) project is a theoretical and experimental project developing the lunar Cherenkov technique for the next generation of giant radio-telescope arrays. This contribution presents our simulation results on the directional dependence of the technique for UHE neutrino detection. In particular, these indicate that both the in...
متن کاملATCA and CMB anisotropies
Australia Telescope Compact Array (ATCA) observations in sky regions selected to be low in foreground confusion have been used to infer limits on arcmin-scale CMB anisotropy in total intensity and polarization. These deep searches have, hitherto, been made using the East-West ATCA in an ultra-compact 1-D array configuration and in the highest available frequency band at 3-cm wavelength. The ATC...
متن کاملAnalysis Strategy for Large-Zenith-Angle-Observations with the HEGRA Cherenkov Telescope CT1
Cherenkov telescope observations at zenith angles > 70o are capable of providing large collection areas. This improves the detection efficiency for photons at very high energies. In order to understand the telescope’s performance extended Monte Carlo studies have been made taking the first HEGRA Cherenkov telescope CT1 as an example. First results of these studies will be presented.
متن کاملThe Australia Telescope Compact Array Broadband Backend (CABB): Description & First Results
Here we describe the Compact Array Broadband Backend (CABB) and present first results obtained with the upgraded Australia Telescope Compact Array (ATCA). The 16-fold increase in observing bandwidth, from 2× 128 MHz to 2× 2048 MHz, high bit sampling, and addition of 16 zoom windows (each divided into a further 2048 channels) provide major improvements for all ATCA observations. The benefits of ...
