Cycle 8 Call for Proposals: LWA Radio Observatory<br class="">
<br class="">
We invite applications for observing time with the LWA Radio Observatory. At this time proposers can request observations with LWA1, LWA-SV, or an interferometry mode between the two.<br class="">
<br class="">
LWA1 offers up to three independently-steerable wide-band beams. Each beam supports two independent tunings over the LWA1 frequency range from 10 to 88 MHz with a FWHM ranging from 15 to 2 degrees. Each tuning can cover up to 20 MHz bandwidth. Two all-dipole
modes are also available; a transient buffer narrow (TBN), and a transient buffer wide (TBW).<br class="">
<br class="">
LWA-SV offers up to two beams with 2 tunings of 20 MHz each. The two tunings are dependent between the beams, and thus need to be at the same frequency. In addition, two all-dipole modes are available; a transient buffer narrow (TBN) and a transient buffer
frequency domain (TBF). At LWA-SV there is also a commensal all-sky broadband imaging system (BIM) that provides images of the sky over 20 MHz of bandwidth at a 10 s cadence.<br class="">
The frequency range of the image data is set by the first beam tuning.<br class="">
<br class="">
For the interferometer mode two beams are used at both LWA1 and LWA-SV, one-beam for calibration and the other beam for the target source. The correlation produces a fan-beam on the sky with a phase center that is affected by the ionosphere. The bandwidth
available is 2 tunings of 20 MHz each. For details about the observing setup and data reduction see the online tutorial at: <a href="http://www.phys.unm.edu/~lwa/singleB_tutorial.pdf" class="">http://www.phys.unm.edu/~lwa/singleB_tutorial.pdf</a><br class="">
<br class="">
The deadline for application is midnight MST on November 1, 2019 and covers observations expected to occur in the 2020 calendar year. The complete call for proposals including a cover page can be found at <a href="http://lwa.unm.edu/" class="">http://lwa.unm.edu</a>.
Support for operations and continuing development of the LWA is provided by the National Science Foundation under grant AST-1835400 of the MSIP program, AGS-1708855 and the Air Force Research Laboratory. We invite proposals from all communities wishing to
use this instrument.<br class="">
<br class="">
More information about the capabilities of the LWA1 can be found on the LWA web pages <a href="http://www.phys.unm.edu/~lwa/status.html" class="">http://www.phys.unm.edu/~lwa/status.html</a>. An introduction to using the LWA1 is also available at <a href="http://www.ece.vt.edu/swe/lwa1/" class="">http://www.ece.vt.edu/swe/lwa1/</a>.<br class="">
<br class="">
