eROSITA

In 2015, CAASTRO and eROSITA_DE signed a Memorandum of Understanding (MoU) that enables collaboration on projects requiring combined data from eROSITA (to be launched in 2016) and from Australian wide-field facilities (including ASKAP, MWA, SKAMP, Parkes, ATCA, SkyMapper, AAT, TAIPAN). To briefly summarise, this will oversee science projects that:

  • require the use of both eROSITA_DE and CAASTRO data
  • involve at least one member from each of eROSITA_DE and CAASTRO
  • do not conflict with existing eROSITA_DE or CAASTRO projects
  • (optionally) allow participation by undergraduate and postgraduate students
  • adhere to the existing policies for the individual facilities involved (e.g. proprietary periods, data access, survey teams, observing time, publications)

Such projects will be formally proposed to, approved by and monitored by a joint CAASTRO/eROSITA_DE Management Committee, as per the details in the MoU. The CAASTRO/eROSITA_DE Management Committee currently consists of :

  • Prof Paul Nandra (eROSITA_DE)
  • Prof Elaine Sadler (CAASTRO)
  • Dr Andrea Merloni (eROSITA_DE) and
  • Ms Kate Gunn (CAASTRO).

If you instead have just a nice idea, and wish to express interest  in developing it, or to be put in touch with potential collaborators within the partner organisation, please complete the expression of interest (EoI) form (see Resources below), and send to coo@caastro.org.  

Full proposals should be submitted by completing the project template form (see Resources below), and sending it to coo@caastro.org.
