When stars like our Sun use up all their fuel, they shrink to form white dwarfs. Sometimes such dead stars flare back to life in a super-hot explosion, called a “nova”, and produce a fireball of X-ray radiation. Using the eROSITA telescope on the SRG space observatory, a research team led by Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) has now been able to observe such an explosion of X-ray light for the very first time. more

Using the SRG/eROSITA all-sky survey data, scientists at the Max Planck Institute for Extraterrestrial Physics have found two previously quiescent galaxies that now show quasi-periodic eruptions. The nuclei of these galaxies light up in X-rays every few hours, reaching peak luminosities comparable to that of an entire galaxy. The origin of this pulsating behaviour is unclear. A possible cause is a stellar object orbiting the central black hole. As these galaxies are relatively close and small, this discovery could help scientists to better understand how black holes are activated in low-mass galaxies. more

Gigantic hot-gas structures above and below the galactic disc are probably due to shock waves generated by past energetic activity in the center of our Galaxy. more

A study led by Alejandra Yrupe Fresco (Max Planck Institute for Extraterrestrial Physics) during her stay at the Instituto de Astrofísica de Canarias (IAC) has revealed the dim core and the jet structure in the nuclear region of M87, the brightest galaxy in the Virgo cluster. The observations were acquired in early April 2017, almost simultaneously with the Event Horizon Telescope campaign that delivered the world famous first image of the event horizon in a black hole in the nucleus of the galaxy M87. more

X-ray observatory XMM-Newton shows large scale plasma motion more

Launched from Baikonur on July 13th 2019 to the second Sun-Earth Lagrange point (L2), the Russian-German SRG mission has now started its main task. On December 8th, after an extensive program of commissioning, calibration and performance verification of its two X-ray telescopes (ART-XC and eROSITA), the satellite has begun observing the sky in continuous scanning mode. As SRG follows the revolution of Earth, and hence also of the L2 point, around the Sun, it will perform eight complete surveys of the whole sky, one every six months, for the next 4 years. Pre-launch predictions suggest that, over that time, the eROSITA instrument, conceived, designed and built at MPE, should discover approximately 100,000 clusters of galaxies, around 3 million accreting supermassive black holes and half a million active stars. more
