Dear colleagues,

We would like to remind you of the ongoing partnership between the Australian Research Council Centre of Excellence for All-sky Astrophysics (CAASTRO) and the German eROSITA Consortium (eROSITA_DE), which will provide exciting new opportunities for multi-wavelength astronomy projects across the southern sky.

While the MoU was signed by CAASTRO, this agreement covers all Australian astronomers. We are now preparing for a transition from the current eROSITA_DE-CAASTRO MoU to an agreement between eROSITA_DE and an entity representing the entirety of the Australian astronomical community. This transition will take place at the end of 2017, before the official ending date of CAASTRO on 31 March 2018.

In the meantime, significant progress has been made on eROSITA, and on a number of other Australian projects, and we would like to give you a brief update on these.

Following our call for proposals and expressions of intent of last May, the first four collaborative projects have started, and a few more are in the planning.

Given all the above developments, we are now opening a new call for proposals for joint eROSITA_DE/CAASTRO projects. The Proposal submission will be open until Friday 8 December 2017 and the (new) project template is attached. Below, you'll find information on all these three points.

We look forward to hearing your ideas, and to seeing new discoveries emerge from this partnership.

Best Regards,
Andrea, Paul, Elaine and Kate

1) Project updates:
- eROSITA (https://protect-au.mimecast.com/s/rNKaBYf92prAFW?domain=mpe.mpg.de<https://protect-au.mimecast.com/s/rNKaBYf92prAFW?domain=mpe.mpg.de>): all-sky X-ray imaging, 0.5-8 keV, 15"-30" angular resolution; eROSITA_DE covers Galactic longitudes 180 < l < 360. The telescope has been completed, assembled and shipped to Russia for final test and integration into the spacecraft (see https://protect-au.mimecast.com/s/ZXg4BxUoZYlpHx?domain=mpe.mpg.de<https://protect-au.mimecast.com/s/ZXg4BxUoZYlpHx?domain=mpe.mpg.de>). Tests are ongoing. Launch is foreseen in September/October 2018. The first all-sky survey should then be completed in Fall 2019, and it is anticipated that seven more passes of the whole sky will be completed by early 2022.

The eROSITA_DE team have agreed on a program of Early Science (Performance Verification), to be carried out within the first four months of the mission (starting approximately 2 months after launch). The full list of approved proposals, with PIs and relevant leading Working Groups is attached. We also include a schematic of the footprints of the eFEDS equatorial mini-survey, that will cover two of the three NGC equatorial GAMA regions down to the full eRASS:8 all-sky survey depth (which one of these two will depend on the exact launch date).

2) Transition to a new MoU, and extension thereof
CAASTRO has commenced discussions with a national body to consider the transition arrangements for the eROSITA_DE and CAASTRO MoU.  These discussions are ongoing however we would anticipate a new MoU signed by the end of 2017 which will encompass all Australian astronomers.

3) Call for Proposals:
CAASTRO and eROSITA_DE have signed a Memorandum of Understanding (MoU) that enables collaboration on projects requiring combined data from eROSITA 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/AUS data
- involve at least one member from each of eROSITA_DE and CAASTRO/AUS
- do not conflict with existing eROSITA_DE or CAASTRO/AUS 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 attached 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).

At this time, we wish to invite proposals for joint eROSITA_DE/CAASTRO/AUS projects.

- If you wish to propose a fully-formed project, please read clause 9 of the attached MoU, complete the attached project template form, and send to coo at caastro.org<mailto:coo at caastro.org>. Proposals should be submitted by Friday 8 December 2017 in order to be considered at the next MC meeting.

We strongly encourage potential proposer to get in touch with their corresponding partners early on. If you are generically interested in a facility, but do not know who to contact specifically, do not hesitate to ask either the members of the Management Committee, or the contact persons listed below. Also, we remind you that, according to the eROSITA_DE policy, each proposal should be approved by a Working Group before submission (this is now explicitly mentioned in the form).
