Two large cold fronts detected in the galaxy cluster Abell 3558
Astronomers from the University of Alabama in Huntsville have investigated the galaxy cluster Abell 3558 using ESA's XMM-Newton spacecraft. In their results, they detected two large-scale sloshing cold fronts in the outskirts of this cluster. The finding was reported in a paper published August 30 on the pre-print server arXiv.

Astronomers Reveal Marvellous Eclipsing Absorber in Active Galaxy NGC 6814
A research team led by Prof. WANG Junxian and PhD students KANG Jialai from University of Science and Technology of China (USTC) of the Chinese Academy of Science (CAS) has revealed a marvellous, composite eclipsing absorber responsible for a highly distinct X-ray eclipse event in active galaxy NGC 6814 observed with XMM-Newton. The paper, titled as “What can be learnt from a highly informative X-ray occultation event in NGC 6814? A marvellous absorber” was published by Monthly Notices of the Royal Astronomical Society on August 23.

Astronomers discover a new type of stellar object hiding in plain sight
Astronomers have made a thorough forensic study of a star that was torn apart when it ventured too close to a giant black hole and then had its insides tossed out into space. NASA's Chandra X-ray Observatory and ESA's XMM-Newton studied the amount of nitrogen and carbon near a black hole known to have torn apart a star. Astronomers think these elements were created inside the star before it was ripped apart as it neared the black hole.

Astronomers discover a new type of stellar object hiding in plain sight
The object could be an ultra-long period magnetar, a rare type of neutron star with extremely strong magnetic fields that can produce powerful bursts of energy, but also a magnetic white dwarf, the old phase of a Sun-like star. ICE-CSIC researchers Nanda Rea and Francesco Coti Zelati led follow-up observations of this new object using the Gran Telescopio CANARIAS (GTC), the world's largest optical telescope located in La Palma (Canary Islands, Spain), along with ESA's XMM-Newton X-ray telescope, and coordinated the physical interpretation of the results.

White dwarf pulsar discovery confirms new class of star
The discovery of a new “pulsing” binary star system has shed new light on the evolution of stars while confirming a new exotic class of stellar object: the white dwarf pulsar. The follow-up investigation with the ESA satellite XMM-Newton revealed the pulsations in the high-energy X-ray regime, thus confirming the unusual nature of the new object and firmly establishing the white dwarf pulsars as a new class.

An X-ray look at the heart of powerful quasars
Researchers have observed the X-ray emission of the most luminous quasar seen in the last 9 billion years of cosmic history, known as SMSS J114447.77-430859.3, or J1144 for short. The new perspective sheds light on the inner workings of quasars and how they interact with their environment. For this study, researchers combined observations from several space-based observatories: the eROSITA instrument on board the Spectrum-Roentgen-Gamma (SRG) observatory, the ESA XMM-Newton observatory...

The ultra-fast space winds that shape the evolution of galaxies
The research project is called SUBWAYS (SUper massive Black hole Winds in the x-rAYS) and the first results have been published in two papers in Astronomy & Astrophysics. The first of these, led by scholars from the University of Bologna and INAF, is mainly based on data obtained from ESA's XMM-Newton space telescope.

Scientists map gusty winds in a far-off neutron star system
MIT astronomers mapped the “disk winds” associated with the accretion disk around Hercules X-1, a system in which a neutron star is drawing material away from a sun-like star, represented as the teal sphere. The findings may offer clues to how supermassive black holes shape entire galaxies.

Astronomers investigate X-ray spectral variability of active galaxy NGC 7582
Using ESA's XMM-Newton and NASA's NuSTAR space telescopes, astronomers have observed a nearby active galaxy known as NGC 7582. Results of the observational campaign, published March 30 on the arXiv pre-print server, shed more light on the X-ray spectral variability of NGC 7582's active galactic nucleus (AGN).

Astronomers discovered helium-burning white-dwarf
The team has found a binary star system in which matter flows onto the white dwarf from its companion. Bright, so-called supersoft X-rays that result from the nuclear fusion of the spilled gas close to the white dwarf’s surface led to the discovery of the system.

XMM-Newton spies black holes eating the same stars again and again
Two teams of astronomers using ESA’s XMM-Newton space telescope have observed repeated outbursts of light from inactive black holes that partially destroy stars again and again. This discovery is unexpected, since outbursts of black holes usually appear only once when a black hole consumes a star.
