A map has been created that shows all the sources the XMM-Newton X-ray telescope has detected as it moves between specific targets (slew paths).
Astrophysicists used the NuSTAR X-ray telescope to study 52 supermassive black holes (SMBHs) in nearby merging galaxies to improve our understanding of the relationship between a black hole and the galaxy it lives in.
Astrophysicists used data from NASA’s Chandra X-ray Observatory in conjunction with radio observations and computer simulations to find the origin of one of the mysterious features that have been observed in the Perseus galaxy cluster.
Athena, the X-ray telescope scheduled to launch in 2028 and the SKA project, the largest radio telescope explore foreseeable scientific synergies.
Scientists used the MUSE and X-shooter instruments on the Very Large Telescope (VLT) at ESO’s Paranal Observatory in Chile, to detect for the first time stars that are created inside colossal winds of material.
NASA’s Chandra X-ray Observatory detected a mysterious flash of X-rays that scientists have never seen before. The source is located in a sky region known as Chandra Deep Field-South (CDF-S) and when erupted it became 1,000 brighter in a few hours producing a thousand times more energy than all the stars in its host galaxy.
On February 2 NASA’s satellite, Swift, was hit by cosmic gamma rays. This triggered an alert and seconds later University of WA’s Zadko Telescope swung into robotic action to take images and record the entire evolution of the event. The event appeared as a rapid brightening visible in the sky for a brief period of time. Its brightness was equivalent to millions of stars shining together from the same location. What was actually detected is known as a Gamma Ray Burst.
A star is disrupted violently when it wanders in the vicinity of a supermassive black hole. Until today, we have observed only a few of these events. Now astronomers say that they can predict where the next stellar disruption will happen, as they found the type of galaxy these events prefer.
Astronomers built a virtual telescope by linking a large array of radio receivers around the world. The telescope is called “Event Horizon Telescope” and will observe for the first time the “edge” of the black hole at the centre of our galaxy.
Using NuSTAR and ESA’s XMM-Newton telescope, astrophysicists observed, for the first time, winds from a nearby black hole to change temperatures rapidly.
