Release of the new version the XMM-Newton Serendipitous Source
Catalogue 3XMM (DR6)
---------- ---------------------------------------------------

A  new version of  the XMM-Newton  EPIC Serendipitous  Source Catalogue,
3XMM-DR6, has been released. The  catalogue includes more than two years
of  additional data  with respect  to 3XMM-DR5,  with  678680 detections
which relate to  468440 unique sources from 9160  observations that were
public by the 31st January 2016.  3XMM-DR6 covers a total sky area, with
at least  1 ks exposure,  of ~982 square  degrees if overlaps  are taken
into account, where some regions of the sky have been pointed as many as
50 times.  This represents an  increase of approximately 18% in terms of
unique sources compared with 3XMM-DR5,  that was released in April 2015.
Around 10% of the detections are classified as extended, and spectra and
time  series have been  extracted for  around 22%  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  prior 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 the  paper Rosen, Webb, Watson et  al. 2016, A&A, 590,  1. 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 (rather than per
detection as in the main catalogue) and a reduced number of columns that
essentially pertain to the unique source quantities.

Alongside the XSA user interface, 3XMM is also distributed through:

XCATDB .... http://xcatdb.unistra.fr/3xmmdr6
LEDAS ..... http://www.ledas.ac.uk
HEASARC ... http://heasarc.gsfc.nasa.gov/W3Browse/xmm-newton/xmmssc.html

XSA v9.1 release with access to the 3XMM (DR6) Catalogue

A new version of the  XMM-Newton Science Archive (XSA v9.1) is available


It includes  access to  the incremental version  of the  EPIC (3XMM-DR6)
catalogue  and, among  other improvements,  a new  visualisation  of the
results for a search on a list of objects.

Details can be found at


Release of ESASky v1.0

The first version of ESASky has been released and can be accessed at


This new web service  provides multi-wavelength visualization and access
to the public data of  ESA astronomy missions, and some non-ESA missions
that are  being incorporated regularly.  It uses Aladin Lite,  which has
been developed at  the Centre de Donnees Astronomiques  de Strasbourg in

Progressive  XMM-Newton EPIC  and OM  images have  been  integrated into
ESASky by projecting the footprints of the exposures onto the sky.  They
can  be visualized  together with  similar high-level  data  products of
other missions.  EPIC and OM  catalogue sources, as well as sources from
catalogues in other wavelengths, can be overlaid on the sky images.

Direct links  from the  ESASky images and  catalogues to  the XMM-Newton
Science Archive (XSA)  allow to get specific information  or to download
the selected data.

FLIX upper-limit server updated

The FLIX  upper-limit server,  a service hosted  by LEDAS,  has recently
been  updated  to include  all  observations used  in  DR5  of the  3XMM
serendipitous source catalogue. This tool is available at


ESA Research Fellowship in Space Science at ESAC

Postdoctoral  fellowships  in the  area  of  Astronomy and  Astrophysics
related  to  the  X-ray   observatory  XMM-Newton  are  tenable  at  the
XMM-Newton  Science Operations  Centre in  the European  Space Astronomy
Centre (ESAC) located in Villafranca del Castillo, near Madrid, Spain.

The European  Space Agency awards several  postdoctoral fellowships each
year.   The aim  of these  fellowships is  to provide  young scientists,
holding a  PhD or  the equivalent degree,  with the means  of performing
space science research  in fields related to the  ESA Science Programme.
The fellowships have a duration of two years.

Applications are now solicited for fellowships in space science to begin
in the fall of 2017.  Preference will be given to applications submitted
by candidates within  five years of receiving their  PhD. Candidates not
holding  a  PhD yet  are  encouraged to  apply,  but  they must  provide
evidence of receiving their degree before starting the fellowship.

Research opportunities with XMM-Newton science staff include: studies of
the high  energy emission of  novae, galaxies, and AGN  using XMM-Newton
data.   Working at  ESAC within  the  XMM-Newton team  gives the  unique
opportunity  of being in  contact with  the calibration  scientists, the
developers of the analysis software and the User Support Group.

Please  contact Norbert  Schartel  (Norbert.Schartel@sciops.esa.int) for
more details on ESA Research Fellowships related to XMM-Newton.

The deadline for applications is

                         29th September 2016

More  information on  the  ESA Research  Fellowship  programme in  Space
Science, on the  conditions and eligibility, as well  as the application
form can be retrieved from
