[ASA] ATNF Telescope Proposals for 2025OCT

[Hobbs, George (S&A, Marsfield)]

Dear ASA members,

Apologies if you receive this multiple times.

Proposals for observing time are now invited for the 2025APR semester for the:

  *   ASKAP radio telescope;
  *   Australia Telescope Compact Array (ATCA);
  *   Murriyang, the CSIRO Parkes Radio Telescope
  *   Tidbinbilla 70-m and 34-m antennas; and
  *   Long Baseline Array (VLBI).

The deadline for all proposals is 07:00 UT (17:00 Sydney local time) on Tuesday, 17 June 2025.

 All proposals must be submitted using the online proposal application system, OPAL (https://url.au.m.mimecastprotect.com/s/nTZ_CGv0oyCAwj0wXIKfRfBErxL?domain=opal.atnf.csiro.au).

 Significant changes for the 2025OCT semester are detailed here and<https://url.au.m.mimecastprotect.com/s/sRQsCJyBrGfKx01xMIGhKfyBPfa?domain=atnf.csiro.au> include:

  *   Since February 2025, the Cryogenically Cooled Phased Array Feed (CryoPAF) has been installed in the focus cabin of Murriyang, CSIRO’s 64-m Parkes radio telescope.
  *   BIGCAT commissioning is underway during 2025APR meaning that BIGCAT will be offered in shared-risk mode during the 2025OCT semester. Since the ATCA schedule for 2025APR has not yet been released, teams that wish to carry over their proposals in 2025OCT can request pre-graded status. Please follow instructions under “Impact of instrument upgrades”.
  *   ATNF proposals are fully anonymised. Proposals that reveal applicant identities will be penalised by a reduction of scores or outright rejection for blatant breaches of anonymity (e.g. self-citations where the first author is listed by name). Please check under “Proposal Guidance” below.
  *   We strongly encourage proposers to use this LaTeX template for ATNF scientific justifications<https://url.au.m.mimecastprotect.com/s/1mlyCK1DvKT4L3BLpC3imf5W0UN?domain=overleaf.com> (with appropriate BibTeX setup to support anonymisation). This template is also now available in the Overleaf template gallery.
  *   ATNF long-term proposals are only accepted once per year at the December deadline. As such, long-term proposals will NOT be accepted this semester.

Details of these changes and other important information on the current status of ATNF telescopes are provided at https://url.au.m.mimecastprotect.com/s/sRQsCJyBrGfKx01xMIGhKfyBPfa?domain=atnf.csiro.au
