XSA v8.4 release with access to the 3XMM (DR5) and OM (SUSS2.1) catalogues

A  new  version  of  the  XMM-Newton Science  Archive  (XSA v8.4)  is
available at


It includes,  besides several improvements, access  to the incremental
versions of the EPIC (3XMM-DR5) and OM (XMM-SUSS2.1) catalogues.

- Release of the new version of the XMM-Newton Serendipitous
  Source Catalogue:  3XMM (DR5)

A new  version of the XMM-Newton EPIC  Serendipitous Source Catalogue,
3XMM-DR5, has been  released. The catalogue includes an  extra year of
data with respect to 3XMM-DR4  and corrects minor issues that exist in
earlier catalogue versions.

The  3XMM-DR5 catalogue  contains  565962 detections  which relate  to
396910 unique sources  from 7781 observations that were  public by the
31st December 2013. 3XMM-DR5 covers a  total sky area, with at least 1
ks  exposure,  of ~877  square  degrees  if  overlaps are  taken into
account, where some regions of the sky have been pointed as many as 48
times. This  represents an  increase of approximately  7% in terms of
unique sources compared with 3XMM-DR4.

Around 10% of  the detections are classified as  extended, and spectra
and time  series have  been extracted for  around 25% of  the sources.
The positional  uncertainty of  the catalogue detections  is generally
less than 3 arcseconds (90% confidence) and the astrometric quality of
3XMM  is   improved  with  respect  to   previous  releases. Typical
sensitivities in  the catalogue are  ~6E-15 and ~1.5E-14 erg/cm2/s in
the soft (0.2-2 keV) and hard (2-12 keV) X-ray band, respectively.

The creation of  the 3XMM catalogue is a joint  venture carried out by
the  XMM-Newton Survey  Science Centre  Consortium.  The catalogue is
described in  Rosen, Webb, Watson  et al.  2015, (A&A, submitted, see
http://arxiv.org/abs/1504.07051). Details   of  the  catalogue,  the
catalogue files and full 3XMM documentation are available at


FITS files containing summary  information about the observations used
in the catalogue are also provided.  FITS and CSV versions of the full
3XMM  catalogue and  a  slimline version  of  the FITS  file are also
available for download at


The slimline version has only one  row per unique source and a reduced
number  of  columns that  essentially  pertain  to  the unique source

Alongside the XSA user interface at


3XMM is also distributed through

- Incremental version of the XMM-Newton OM Catalogue (XMM-SUSS2.1)

The  OM Serendipitous Ultraviolet  Source Survey  Catalogue (XMM-SUSS)
has been  updated with the  inclusion of all observations obtained in
2013 (XMM-SUSS2.1).   The new data  have been processed with  the same
SAS version as the already existing ones, namely SAS v14.

The observing  period covered by  the catalogue is now  2000-2013. The
total number of entries is 6.25 million.  They correspond to more than
4 million  sources, of  which 19% have  multiple entries,  coming from
different observations.   The number  of observations included  in the
catalogue is 7170.

The  XMM-SUSS  catalogue  can  be  accessed  through  the  XSA search
interface.   Besides,  either  the  complete catalogue  or  a reduced
version of it can be downloaded at


Users Group meeting #16: Invitation from UG chair to contact them

The XMM-Newton  Users Group  (UG) will be  holding its  yearly meeting
this coming May 21st and 22nd, at ESAC in Spain. This will be my first
meeting as  Chair of  the UG, having  taken over from  Xavier Barcons,
whom I would like to thank personally, and I believe also on behalf of
the wider community  for all his efforts in  support of the XMM-Newton
project, over the years.

The UG welcomes all comments and suggestions on any relevant aspect of
XMM-Newton operations and future  direction. You may send these either
directly to me, or if you prefer  to any member of the UG.  So that we
will be  able to collate your inputs  for the meeting, I  ask that you
e-mail them  before Friday May  15th.  Together with your  support and
feedback,  the  UG  will  advise   the  project  and  help  to ensure
continuation of XMM-Newton???s unique contribution to astrophysics.

Martin Ward,  UG-Chair

The agenda for UG meeting #16  and contact information of the UG chair
and all the other UG members are available at


Second Announcement: "Exploring the Hot and Energetic Universe"

As  announced in  a  previous  issue of  this  Newsletter (#171), the
conference  "Exploring  the  Hot  and Energetic  Universe:  The first
scientific conference dedicated to  the Athena X-ray observatory" will
take place from 8th to 10th September 2015 at ESAC, Madrid, Spain.

The Second Announcement inviting  for contributed talks and posters is
available now,  together with information  on the draft  programme and
accommodation, from the conference website at:


Abstract  submission is  possible until  Monday, 1st  June  2015. The
Registration deadline is Friday, 21st August 2015.

Yours sincerely,
