Mystery objects stump astronomers Posted March 24, 2005
Special to World Science

Astronomers are puzzled by two vast objects in our galaxy that spew powerful
radiation, yet appear pitch black.

The objects are not black holes, which generally are smaller and which,
despite their name, do seem to emit visible light, though that light
actually comes from around them and not inside them.

The two bizarre objects were detected in a survey of sources within our
galaxy of very high-energy gamma rays. Gamma rays are a type of light that
is the most powerful known, yet is invisible to our eyes.

The objects appear to be light-years wide, the astronomers said. This would
make them bigger than our Solar System-as measured not just out to the
furthest known planet, but all the way out to the distant Oort Cloud of
comets that surrounds our system, 1,000 times further. A light year is the
distance light travels in a year.

The newfound objects are also distinct from another, well known type of
gamma-ray source called gamma-ray bursts-momentary flashes of gamma rays,
detected about once a day, which astronomers think may signal the birth of
black holes as dead stars abruptly shrink out of existence.

Astronomers have dubbed the mystery objects dark accelerators.

"They are, for the moment, a complete mystery," said Paula Chadwick of the
University of Durham, U.K., one of the researchers. Durham is a member of an
international team of astrophysics who found the objects and reported the
findings in the March 25 issue of the research journal Science.

Astrophysicists use the term "accelerator" to refer to objects or violent
processes, such as stellar explosions, that swing electrically charged
particles up to high speeds. These events also emit gamma rays, which are
easier to detect than charged particles because they travel outward in
straight lines, unlike the particles, which are deflected by magnetic
fields.

In addition to emitting gamma rays, most accelerators also radiate light of
various other energy ranges. But the new dark accelerators appear to emit
the very highest energy gamma rays only.

The group of researchers, known as the High Energy Stereoscopic System team,
obtained the results using a special set of four gamma-ray detecting
telescopes in Namibia, in South-West Africa, similarly called the High
Energy Stereoscopic System.

Survey Finds Dark Accelerators

Summary - (Mar 28, 2005) A team of European astronomers has found some
unusual objects in the central part of our galaxy which are emitting very
high-energy gamma rays. What's strange, though, is these objects are
invisible in the optical and X-ray spectra. So what they are is a complete
mystery. Not only that, but these objects are also quite large; possibly on
the order of several light years across. The observations were done using
the High Energy Stereoscopic System (H.E.S.S.) telescopes in Namibia.

Full Story - In the March 25th 2005 issue of Science Magazine, the High
Energy Stereoscopic System (H.E.S.S.) team of international astrophysicists,
including UK astronomers from the University of Durham, report results of a
first sensitive survey of the central part of our galaxy in very high energy
(VHE) gamma-rays. Included among the new objects discovered are two 'dark
accelerators' - mysterious objects that are emitting energetic particles,
yet apparently have no optical or x-ray counterpart.

This survey reveals a total of eight new sources of VHE gamma-rays in the
disc of our Galaxy, essentially doubling the number known at these energies.
The results have pushed astronomy into a previously unknown domain,
extending our knowledge of the Milky Way in a novel wavelength regime
thereby opening a new window on our galaxy.

Gamma-rays are produced in extreme cosmic particle accelerators such as
supernova explosions and provide a unique view of the high energy processes
at work in the Milky Way. VHE gamma-ray astronomy is still a young field and
H.E.S.S. is conducting the first sensitive survey at this energy range,
finding previously unknown sources.

Particularly stunning is that two of these new sources discovered by
H.E.S.S. have no obvious counterparts in more conventional wavelength bands
such as optical and X-ray astronomy. The discovery of VHE gamma-rays from
such sources suggests that they may be `dark accelerators', as Stefan Funk
from the Max-Planck Institut in Heidelberg affirms: "These objects seem to
only emit radiation in the highest energy bands. We had hoped that with a
new instrument like H.E.S.S. we would detect some new sources, but the
success we have now exceeds all our expectations."

Dr Paula Chadwick of the University of Durham adds "Many of the new objects
seem to be known categories of sources, such as supernova remnants and
pulsar wind nebulae. Data on these objects will help us to understand
particle acceleration in our galaxy in more detail; but finding these 'dark
accelerators' was a surprise. With no counterpart at other wavelengths, they
are, for the moment, a complete mystery."

Cosmic particle accelerators are believed to accelerate charged particles,
such as electrons and ions, by acting on these particles with strong shock
waves. High-energy gamma rays are secondary products of the cosmic
accelerators and are easier to detect because they travel in straight lines
from the source, unlike charged particles which are deflected by magnetic
fields. The cosmic accelerators are usually visible at other wavelengths as
well as VHE gamma rays.

The H.E.S.S. array is ideal for finding these new VHE gamma ray objects,
because as well as studying objects seen at other wavelengths that are
expected to be sources of very high energy gamma rays, its wide field of
view (ten times the diameter of the Moon) means that it can survey the sky
and discover previously unknown sources.

Another important discovery is that the new sources appear with a typical
size of the order of a tenth of a degree; the H.E.S.S. instrument for the
first time provides sufficient resolution and sensitivity to see such
structures. Since the objects cluster within a fraction of a degree from the
plane of our Galaxy, they are most likely located at a significant
distance - several 1000 light years from the sun - which implies that these
cosmic particle accelerators extend over a size of light years.

The results were obtained using the High Energy Stereoscopic System
(H.E.S.S.) telescopes in Namibia, in South-West Africa. This system of four
13 m diameter telescopes is currently the most sensitive detector of VHE
gamma-rays, radiation a million million times more energetic than the
visible light. These high energy gamma rays are quite rare - even for
relatively strong sources, only about one gamma ray per month hits a square
meter at the top of the earth's atmosphere. Also, since they are absorbed in
the atmosphere, a direct detection of a significant number of the rare gamma
rays would require a satellite of huge size. The H.E.S.S. telescopes employ
a trick - they use the atmosphere as detector medium. When gamma rays are
absorbed in the air, they emit short flashes of blue light, named Cherenkov
light, lasting a few billionths of a second. This light is collected by the
H.E.S.S. telescopes with big mirrors and extremely sensitive cameras and can
be used to create images of astronomical objects as they appear in
gamma-rays.

The H.E.S.S. telescopes represent several years of construction effort by an
international team of more than 100 scientists and engineers from Germany,
France, the UK, Ireland, the Czech Republic, Armenia, South Africa and the
host country Namibia. The instrument was inaugurated in September 2004 by
the Namibian Prime Minister, Theo-Ben Guirab, and its first data have
already resulted in a number of important discoveries, including the first
astronomical image of a supernova shock wave at the highest gamma-ray
energies.
