A blazar is an active galactic nucleus (AGN) with a relativistic jet (a jet composed of ionized matter traveling at nearly the speed of light) directed very nearly towards the observer. Relativistic beaming of electromagnetic radiation from the jet makes Read More …
Extraordinarily long threads of hot gas known as intergalactic filaments connect and surround galaxies and galaxy clusters throughout the cosmos — and scientists just discovered the longest one yet. The intergalactic filaments make up a cosmic web that stretches across Read More …
#AthenaNuggets 48 deals with Supermassive Black Holes (SMBHs) present in Active Galactic Nucleus (AGN). Its X-ray emission is a unique feature and enables to pierce the inner regions close to the SMBHs. Supermassive black holes are ubiquitous in the center Read More …
The first all-sky survey performed by the eROSITA X-ray telescope on-board the Spektrum-Roentgen-Gamma (SRG) observatory has revealed a large hourglass-shaped structure in the Milky Way. In particular, astronomers have spotted a pair of enormous bubbles of plasma extending above and Read More …
By studying a sample of distant galaxies, whose light comes to us from an era when the Universe was only three billion years old, a team of researchers led by Giustina Vietri of the National Institute of Astrophysics has followed Read More …
The planetarium documentary “The Hot and Energetic Universe” presents with the use of Immersive Visualizations and real images the achievements of the modern astronomy, the most advanced terrestrial and orbital observatories, the basic principles electromagnetic radiation and the natural phenomena Read More …
An international team of astronomers has conducted simultaneous radio and X-ray observations of the magnetar 1E 1547.0–5408 during its period of enhanced activity. In result, new X-ray and radio bursts were detected from this source. The finding is reported in Read More …
A new study using data from NASA’s Chandra X-ray Observatory and Hubble Space Telescope gives new insight into an important question: how habitable are planets that orbit the most common type of stars in the Galaxy? The target of the Read More …
For more than two decades, astronomers have been systematically tracing mystery sources of high-energy gamma rays to their sources. One, however, remained stubborn – the brightest unidentified source of gamma rays in the Milky Way. It seemed to be coming from Read More …
The covid-19 situation suspended all the visits on site, though the visits in EGO and Virgo will be LIVE BROADCASTED from the time beeing! Stay tuned! Galileo’s telescope opened the door to the stars, EGO and Virgo opened a new Read More …
The AHEAD2020 main goal is to integrate and open research infrastructures for high energy and multi-messenger astrophysics. We offer a wide program of transnational access (TNA) to the best European test and calibration facilities and access free of cost to Read More …
Astronomers have measured motions within a remarkable cosmic structure for the first time using NASA’s Chandra X-ray Observatory. The data show a blast wave and debris from an exploded star moving away from the explosion site and colliding with a Read More …
Astrophysicists have used computer simulations to show that in deep in space, tsunami-like structures may form on much bigger scales than here on Earth, from gas escaping the gravitational pull of a supermassive black hole. In fact, the mysterious environment Read More …
IAU Symposium 363: Neutron Star Astrophysics at the Crossroads: Magnetars and the Multimessenger Revolution — 1st Announcement! The 363st International Astronomical Union (IAU) Symposium will be held remotely, November 29th – December 3rd 2021. Neutron stars are the strongest magnets Read More …
Published on Nature Communications the work led by Samuele Ronchini, PhD student at GSSI and INFN associate, together with INAF, which sheds new light on cooling processes happening in jets of Gamma-Ray Bursts. What are the processes that determine the Read More …
After the discovery of quasars (QSO), in the mid-1960s the X-ray astronomy started and was important to understand better the nature and the properties of the Active Galactic Nuclei (AGN), as the X-ray emission seemed to occur in the majority Read More …
A new panorama from NASA’s Chandra X-ray Observatory and the MeerKAT radio telescope provides a stunning view of the center of our Milky Way galaxy. It also reveals threads of superheated gas and magnetic fields, which are weaving a tapestry Read More …
The Athena (Advanced Telescope for High ENergy Astrophysics) mission is the second long-range space mission (L2) of the long term program “Cosmic Vision” of the European Space Agency (ESA). This mission is dedicated to the scientific theme “The hot and Read More …
Black holes are divided, based on their mass, into supermassive black holes (SMBHs) with masses more than 1 million Suns together that reside in the centre of the galaxies and stellar black holes with masses up to 20 times the Read More …
