«It was only a few months ago that our observations showed that
such bursting objects are located far beyond our own galaxy.
Not exact matches
Some might even suggest they may be messages from advanced alien civilisations but many experts have predicted that the
bursts are emitted when jets of particles are thrown out by massive astrophysical
objects,
such as black holes.
The Compton Gamma Ray Observatory (CGRO), designed to detect gamma rays from distant astrophysical
objects such as neutron stars and supernova remnants, had also begun recording bright, millisecond - long
bursts of gamma rays coming not from outer space but from Earth below.
No further
bursts were seen in 90 hours of additional observations, which implies that it was a singular event
such as a supernova or coalescence of relativistic
objects.
«By picking up the gravitational waves associated with these events, we will be able to access precious information that was previously hidden,
such as whether the collision of a star and a black hole has ignited the
burst and roughly how massive these
objects were before the impact,» explained Dr Ohme, who has focused his research on predicting the exact shape of the gravitational wave signals scientists are expecting to see.
Future missions
such as the Joint Astrophysics Nascent Universe Satellite — a small explorer mission being considered by NASA — could give astronomers their first look at gamma - ray
bursts produced by these first - generation stellar
objects.
«NIRES is expected to be one of the most efficient single -
object, near - infrared spectrographs on an eight to ten - meter telescope, designed to study explosive, deep sky phenomena
such as supernovae and gamma ray
bursts, a capability that is in high demand.»
This allows it to study a variety of astronomical
objects,
such as the molecular gas in planetary nebulae, molecules on active comets, the heating mechanisms of red giants and the afterglows of gamma - ray
bursts.
Enrico Ramirez - Ruiz studies stellar explosions, gamma - ray
bursts and how material accretes onto dense
objects such as black holes and neutron stars.
Besides keeping an eye out for the right coloured balloons, players must also watch out for
objects such as helicopters and spaceships that will
burst your balloons and make an inky mess on the iPhone screen.
These may include Autofocus
burst, which tracks and captures sequences of moving
objects in sharp focus to avoid blurred action shots, and Predictive Capture that attempts to capture unexpected motion
such as your child's smile.
