Dear Emma,
thanks for the thoughts.
As for the next steps, there is no need to write a preliminary proposal.
ESA states:
... interested scientists are strongly urged to
send an e-mail as letter of intent to the XMM-Newton Project
Scientist (Norbert.Schartel + esa.int )
before 6 March 2020. The e-mail should contain a
draft title, a short (up to three sentences) description of the
respective scientific area and an estimate of the required
observing time.
We 'only' need to understand whether we believe we want to put in the effort
to write a good heritage program.
As far as I see, preliminary considerations would be:
- what can we achieve with 2-4Ms of XMM time that is sufficiently
interesting not only for us but also for the wider community?
It would be key to argue that such a program will enable science that
cannot be done otherwise.
- there are already decent observations of many HESS sources (see Emma's
plots).
- a wide/shallow coverage would need to significantly exceed eROSITA's job
(even if the data are not public)
- a deeper coverage needs tiling (XMM-fov) and yet the total time must
clearly go beyond a handful of sources.
Best,
Stefan
Dear Stefan,
thanks for bringing this up.
I like very much the idea of pursuing a heritage program with XMM, but I
wonder if the X-ray properties of the Galactic TeV sources is a bit too
wide to really have an impact. We can discuss further in Heidelberg, but
since we need to have a preliminary proposal by the 6 of March (not sure
if that’s correct?), maybe we could discuss it a bit online? Below I wrote
a few thoughts...
For the general XMM follow-up of the HGPS, I see two (I guess obvious)
problems: 1/ the size of the HESS are too large wrt the XMM FoV, 2/ there
is already a large coverage of many of them, with different exposures. See
as an example the plot below on the Galactic center region (contours are
HESS on the XMM observations)
and here for a much larger region
We need a major effort to understand the coverage and the needed
pointings. Maybe we could focus it on the unidentified bright sources and
have a full coverage on them?
* There are 47 sources classified as unidentified in the HGPS, from those,
~10 are bright above 1 TeV (>0.05 Crab), in which you would expect X-ray
counterparts. The high energy part would give us also a better
localisation of the emitter, and decrease the number of points…
* A second possibility I can think of could be to focus on the VHE
shell-like SNRs. For the brightest ones (Vela Jr., J1713) there is already
quite a bit of coverage, but maybe for the new ones (or candidates) we can
try to get some time?
My 2 cents, hope this helps to shape a good proposal!
Best wishes
Emma

Dear all,
I cc Gerd (who will be interim chair of the new OC until the OC will
elect
a chair in Obergurgl) for information.
last fall I participated again in the xmm review. In the meeting of
panel
chairs we recommended the Multi-Year Heritage Programme of XMM for
continuation.
Based on the discussions among the XMM panel chairs, I thought that we
may
consider this in HESS as well.
The XMM plan for Multi-Year Heritage Programms has now been approved and
has been announced (see below).
I wonder whether we should consider a proposal to study, e.g., the X-ray
properties of the Galactic TeV sources. This would combine the efforts
of
the entire Galactic science in HESS. We should be clear that a proposal
would be a significant amount of work (last round's proposals were VERY
GOOD) but I think we would now have a good chance (with the published
HGPS out, etc.)
An obvious option would be to propose this effectively by HESS (Co-Is
would have to be individual HESS members). Please feel free to consider,
to comment, to discuss in your groups. I suggest we discuss this
briefly
on Feb 25/26. In case we wanted to go this way, we ought to prepare the
LOI
mentioned in the announcement at that mtg.
Best regards,
Stefan

Letter of Intent for Multi-Year Heritage Programmes
In the next call for XMM-Newton proposals (20th Announcement of
Opportunity) a "Multi-Year Heritage Programme" will be offered for
the second time.
This programme seeks scientific visionary projects which require
at
least 2 Ms of observing time. A total of 6 Ms of observing time,
spread over three years, is planned to be made available for this
programme.
In order to organise the evaluation of "Multi-Year Heritage
Programme" proposals, interested scientists are strongly urged to
send an e-mail as letter of intent to the XMM-Newton Project
Scientist (Norbert.Schartel + esa.int ) before 6 March 2020.
The e-mail should contain a draft title, a short (up to three
sentences) description of the respective scientific area and an
estimate of the required observing time.
Anticipated timeline for next XMM-Newton Announcement of
Opportunity: AO-20
The planned key milestones for the Twentieth XMM-Newton
"Announcement of Opportunity" have been established. Within this
AO-20 a new call to submit proposals for observations to be
performed with the XMM-Newton observatory will be issued.
To be prepared for this, please find below the anticipated
timeline:
Announcement of Opportunity
18 August 2020
Due date for Proposals 9
October 2020 (12:00 UT)
Final OTAC approved programme
mid December 2020
For approved
proposals only:
Start of Phase II
proposal submission 11
January 2021
Closure of Phase II proposal submission
5 February 2021
Start of observations
May 2021
The official "Announcement of Opportunity" will be made public in
the XMM-Newton News and on the XMM-Newton Science Operations
Centre Home Page.
Let us know about XMM-Newton related Ph.D.
As already announced in previous issues of this Newsletter, the
XMM-Newton team is collecting information about the completion of
doctorates and Ph.D. theses based on (or making use of) XMM-Newton
observations.
We would appreciate if you - being a candidate or a supervisor of
a
doctorate - could let us know details through the page
http://www.cosmos.esa.int/web/xmm-newton/phd-theses
Also, we would be grateful if you could inform us (via a message
to
xmmhelp(a)sciops.esa.int, with subject "Ph.D. thesis work") in case
you are aware of theses from, or supervised by, colleagues that
make use of XMM-Newton data but are not yet included in the above
list.
