XMM-Newton Twenty-third Announcement of Opportunity (AO-23)

 

The Announcement of Opportunity is closed now

Effective 17 August 2023, XMM-Newton observing proposals were solicited in response to the Twenty-third Announcement of Opportunity, AO-23.

A letter from ESA's Director of Science, inviting you to participate in the Twenty-third Call for Proposals, is available in electronic form.

The deadline for XMM-Newton AO-23 proposal submission was Friday 6 October 2023, 12:00 UT.

Important changes for AO-23 relative to earlier Calls

(see the Policies and Procedures Document)

Multi-Year Heritage Programmes offered in this AO

Scientifically visionary programmes which require more than 2 Ms of observing time may be proposed as "Multi-Year Heritage Programmes".

These programmes may be accepted for observation over three consecutive AOs.

In total, up to 6.0 Ms of observing time may be allocated for this type of programmes.

"Multi-Year Heritage Programmes" will be reviewed by the Senior Review Panel, which will be a special and separate panel within the Time Allocation Committee.

 

New Join Programme

A new Joint Programme with JWST is offered in this AO.

The XMM-Newton Project may award up to 40 hours of JWST observing time.

Full details are given in the Policies and Procedures Document.

 

Maximum observation duration

Due to he evolution of the XMM-Newton orbit, the fraction of the orbit during which the spacecraft is close to perigee, and hence instruments are affected by high background, is slowly increasing with time.

To be in-line with the actual duration of the science window, the maximum exposure time that can be entered in XIPS has been set to 120 ks. This value does not include overheads, that will be added automatically by the system.

 

Proposal Submission System: XIPS

Access to the Phase I submission system (XIPS) requires login with the ESA-Cosmos account credentials, the same used to log in to the XMM-Newton Science Archive (XSA).

Registration in ESA-Cosmos can be done via

    https://www.cosmos.esa.int/web/xsa/self-registration

Forgotten usernames and/or passwords can be recovered through the XSA or XIPS login boxes.

AO-21 and AO-22 proposals are available to be copied for edition and re-submission in AO-23.

Proposers are advised to become familiar with the system well in advance to avoid last minute problems.

XIPS is available at

    http://xmmrps.esac.esa.int/xips/

 

Reminder: Length of Scientific Justification

The maximum number of pages allowed for the scientific justification of the different types of proposals is:

Multi-Year Heritage Programmes: 8 pages
Large Programmes: 5 pages
Fulfil Programmes: 2 pages
Other Programmes: 4 pages

This limit includes all accompanying material, like the section on the feasibility of the proposed observations, figures, tables, references, previous work and publications.

Proposal Submission Documentation

The following AO-23 documentation is available:

Letter by the Director of Science announcing AO-23 pdf
Policies and Procedures for the XMM-Newton AO-23 pdf
XMM-Newton Users Handbook (UHB) on-line, pdf
XMM-Newton Scientific Justification LaTeX Template LaTeX File

On-line documentation contains updated links to references in the text.

The XMM-Newton SOC highly recommends the use of the Scientific Justification LaTeX Template (see further instructions at the end of this page).

AO-23 Timetable

Key milestones for AO-23 are

Announcement of Opportunity 17 August 2023
Due date for Proposals 6 October 2023 (12:00 UT)
Final OTAC approved programme mid December 2023
   
For approved proposals only:  
Start of Phase II proposal submission 9 January 2024
Closure of Phase II proposal submission 2 February 2024
Start of AO-23 observations May 2024

 

Approved AO-23 observations are planned to be performed during the period May 2024 to April 2025 (XMM-Newton revolutions 4468-4650).

Proposal Submission Procedure and Tools

XMM-Newton Proposals were submitted using the XMM-Newton Interface for Proposal Submission software:

XMM-Newton Interface for Proposal Submission

 

The following tools are available to assist AO-23 proposers:

  • Visibility Checker Tool
    Check if a target is visible with XMM-Newton

  • Sky Visibility Map
    Check visibility constraints for any position on the sky during this AO

  • Observation Lokator
    Check if a target has been observed or is awaiting observation by XMM-Newton

  • Pending Anticipated ToOs
    Check if a target has already been accepted as anticipated ToO, and find the validity period of the corresponding proposal

  • EPIC Exposure Map Simulator
    For XMM-Newton Mosaic Mode

  • xmm_footprint.tpl (for ds9), xmm_footprint.xml (for Aladin)
    EPIC-pn footprint templates
    These files can be downloaded and be used as templates for ds9 and Aladin viewers. They should be loaded as Region-Template-Load (in ds9) and FOV (in Aladin).
    The Position Angles with which a given object can be observed with XMM-Newton can be obtained with the Visibility Checker Tool.

Using the LaTeX Template File

Use of the provided LaTeX template to write the scientific justification is highly recommended.

Proposal justifications MUST be submitted as one file in Portable Document Format (PDF). A PDF file can be generated from the LaTeX template in one of two ways:

  1. Use a LaTeX installation which allows you to create PDF files directly from the .tex file (e.g. pdflatex). Some installations of pdflatex do not allow you to include postscript figures. In this case you might use method 2.

  2. Use ps2pdf (preferably version 1.4) to convert the postscript file to PDF:
    > latex file.tex
    > dvips -Ppdf -G0 -o file.ps file.dvi
    > ps2pdf14 file.ps file.pdf

Please take note of the following points regarding the use of the LaTeX template provided:

  • Proposers must make sure that generated pdf output from the template is complete both when displayed with a viewer (acroread) and when printed on paper. LaTeX installations vary greatly and therefore it might not be possible to get all proposals to come out correctly with a single text page layout. In some cases the user will have to adjust the \topmargin=-7mm command in the template to vertically centre the text.

  • The page limit of 4 pages (5 pages for "Large Programmes", 2 pages for "Fulfil Programmes") includes all materials, i.e. science justification and Sections 4 and 5 (previous work and publications).

  • Color images are allowed and proposals are distributed to OTAC in electronic form. However, the scientific content of images should still remain clear when displayed or printed in black and white.

  • The proposal justification can be submitted in single or in two-column format. Instructions on how to switch between these two layouts are given in the LaTeX template.

  • The font size (11pt) is mandatory.

All questions regarding XMM-Newton proposal submission should be directed to the XMM-Newton HelpDesk.
