PJ352-15: Gigantic Jet Spied From Black Hole in Early Universe!

March 21, 2021March 21, 2021 Ektoras PouliasisArticle

Astronomers may have found the most distant supermassive black hole with a jet detected in X-rays using NASA’s Chandra X-ray Observatory. The source of this jet is a quasar — a rapidly growing supermassive black hole — named PSO J352.4034-15.3373 Read More …

eROSITA X-Ray Telescope Spots Enormous Supernova Remnant!

March 11, 2021March 11, 2021 Ektoras PouliasisArticle

In the first all-sky survey by the eROSITA X-ray telescope onboard SRG, astronomers at the Max Planck Institute for Extraterrestrial Physics have detected the largest in terms of apparent size supernova remnant ever observed in X-rays. The supernova remnant (SNR) Read More …

Talk: “AGN Warm Absorbers: The Rosetta Stone of AGN phenomenology?” by Prof. D. Kazanas (NASA/GSFC)

March 9, 2021March 9, 2021 Ektoras PouliasisEvent

The Section of Astrophysics, Astronomy and Mechanics of the Department of Physics of the National and Kapodistrian University of Athens in Greece offers a series of virtual Colloquia in Astrophysics, every Wednesday at 6pm EET. The Spring Colloquium Sessions of Read More …

Talk: “ALMA: the soul of (sub)mm astronomy” by Dr. Evanthia Hatziminaoglou (ESO, Germany)

March 9, 2021March 9, 2021 Ektoras PouliasisEvent

The Hellenic Astronomical Society organizes its 6th Monthly Colloquium of HelAS – 9 March 2021with invited speaker Dr. Evanthia Hatziminaoglou from the European Southern Observatory (ESO) in Germany. This event will happen on Tuesday, 9 March 2021 at 18:00 Athens Read More …

E0102-72.3: A Distant and Lonely Neutron Star!

March 8, 2021March 8, 2021 Ektoras PouliasisImage

Neutron stars are the ultra dense cores of massive stars that collapse and undergo a supernova explosion. This neutron star is located within the remains of a supernova — known as 1E 0102.2-7219 (E0102 for short) — in the Small Read More …

Super-bubbles found in the galaxy NGC 3079!

March 2, 2021March 3, 2021 Ektoras PouliasisImage

The galaxy NGC 3079, located about 67 million light years from Earth, contains two “super-bubbles”. A pair of balloon-like regions stretch out on opposite sides of the center of the galaxy: one is 4,900 light years across and the other Read More …

NASA’s Swift Helps Connect Neutrino to Star-shredding Black Hole!

March 1, 2021March 3, 2021 Ektoras PouliasisArticle

For only the second time, astronomers have linked an elusive particle called a high-energy neutrino to an object outside our galaxy. Using ground- and space-based facilities, including NASA’s Neil Gehrels Swift Observatory, they traced the neutrino to a black hole Read More …

Reclusive Neutron Star May Have Been Found in Famous Supernova!

February 28, 2021February 28, 2021 Ektoras PouliasisArticle

Since astronomers captured the bright explosion of a star on February 24, 1987, they have been searching for the squashed stellar core that should have been left behind. A new study from two NASA X-ray telescopes may have finally been Read More …

Cartwheel Galaxy in optical and X-rays!!

February 20, 2021February 20, 2021 Ektoras PouliasisImage

This galaxy resembles a bull’s eye, which is appropriate because its appearance is partly due to a smaller galaxy that passed through the middle of this object. The violent collision produced shock waves that swept through the galaxy and triggered large amounts Read More …

Data Sonification: Listen to the Sounds of the Universe!

February 19, 2021February 19, 2021 Ektoras PouliasisVideo

A new project using sonification turns astronomical images from Chandra and other telescopes into sound. This allows users to “listen” to the center of the Milky Way as observed in X-ray, optical, and infrared light. As the cursor moves across Read More …

Are you ready to explore the X-ray Universe?

Welcome to CLAXSON!

(Classification of X-ray Sources for Novices)

Now available in EN, FR, ES and GR!

CLAXSON is a platform that trains you to identify new objects observed in the X-ray sky with the European Space Agency X-ray telescope XMM-Newton. Be the first to find new supermassive black holes, stars, galaxies and other exotic objects in observations taken over the last 20 years, and help astronomers unravel the mysteries of the X-ray sky.

Invitation to submit news

Astronomers are invited to advertise their work and/or recent results in our website. Publications/news related to High Energy Astrophysics are of particular interest.
