X-Ray
Astronomy Data Center at the Max-Planck-Institute for Extraterrestrial Physics
( MPE )
Research
activities, data center services, and databases related to the X-ray satellite
ROSAT at the Max-Planck-Institute
for extraterrestrial Physics.
X-Ray
Timing Explorer
( XTE. GSFC.NASA )
The
Rossi X-ray Timing Explorer is a Goddard mission which was launched on December
30th, 1995. RXTE is designed to facilitate the study of time variability in the
emission of X-ray sources with moderate spectral resolution. Time scales from
microseconds to months are covered in an instantaneous spectral range from 2 to
250 keV. It is designed for a required lifetime of two years, with a goal of
five years.
X-Ray
WWW Server
( at Uppsala Universitet )
The
Server makes available bibliographies and databases related to x-ray
spectroscopic physics. In particular, the Henke database of atomic scattering
factors can be downloaded. Also, this is the site for the Atomic and Molecular
Core- Edge Excitation Database and Bibliography, compiled originally by A.P.
Hitchcock, and prepared by Hitchcock and Mancini for electronic distribution (COREXDB).
A simple bibliographic search mechanism has been implemented for the COREX
bibliography. A visualization mechanism is currently being developed to allow
Web Browsers to preview datafiles as in-line GIFs before choosing to download.
X-rays
from Hot Massive Stars
( XMEGA )
This
site is a central location for scientists interested in the problem of X-ray
emission from hot, massive stars. It contains a list of current observational
projects and planned observations. Schedules of currently planned X-ray
observations are also included for those interested in providing ground-based
coordinated observations.
Xephem:
An Interactive Ephemeris for X Windows/Motif
( XEPHEM )
Xephem
is an interactive astronomical ephemeris program for X Windows systems. It
computes heliocentric, geocentric and topocentric information for celestial
objects. Xephem has built-in support for all planets; the moons of Jupiter,
Saturn and Earth and Mars' central meridian longitude. Xephem supports objects
in heliocentric or Earth orbit given the appropriate elements. Sample databases
of over 16000 objects are included in the release kit. Xephem generates data in
configurable tabular forms and in several detailed graphical formats. Xephem can
plot and list all data fields and can be programmed to search for arbitrary
circumstances. Xephem can serve as the control point for automated telescopes
and can connect to auxiliary database servers in real-time via named streams
pipes (UNIX fifos).
Xerox Palo Alto Research Center ( PARC )
XIRAF
- a startup script for IRAF
XIRAF is C shell script which starts up an IRAF session on an xgterm, including
starting an image display of the user's choice (i.e. SAOimage, XImtool, SAOtng).
Its purpose is to provide a simple IRAF startup from Unix/Linux.
XMM
Survey Science Centre
( XMM SSC )
The
XMM Survey Science Centre (SSC) has responsibilities within the XMM
project in three
main areas:
·
the follow-up/identification
programme for the XMM serendipitous X-ray sky survey
·
the development
of science analysis software for XMM
·
the
"pipe-line processing" of all XMM observations.
XMM-Newton
Science Operations Centre
( XMM, ESA )
ESA
s X-ray Multi Mirror mission XMM-Newtion is the second Cornerstone in ESA's Long
Term Scientific Programme. With a large collecting area of its mirrors and the
high sensitivity of its cameras, XMM-Newton is expected to increase radically
our understanding of high-energy sources - clues to a mysterious past, and keys
to understanding the future of the Universe.
XMM-Newton
( ESA )
The
European Space Agency's X-ray Multi-Mirror satellite is the most powerful X-ray
telescope ever placed in orbit. It has an unprecedented sensitivity and the
mission will help solve many cosmic mysteries, ranging from enigmatic black
holes to the formation of galaxies.
