Monster black hole found in the early universe!

June 29, 2020June 29, 2020 Ektoras PouliasisArticle

Astronomers have discovered the second-most distant quasar ever found using three Maunakea Observatories in Hawai’i: W. M. Keck Observatory, the international Gemini Observatory, a Program of NSF’s NOIRLab, and the University of Hawai’i-owned United Kingdom Infrared Telescope (UKIRT). It is Read More …

Our deepest view of the X-ray sky

June 19, 2020June 19, 2020 Ektoras PouliasisArticle

The eROSITA telescope has provided a new, sharp view of hot and energetic processes across the Universe. Over the course of 182 days, the eROSITA X-ray telescope onboard SRG has completed its first full sweep of the sky. This new Read More …

Educational presentations for children!

June 18, 2020June 18, 2020 Ektoras PouliasisShort article

As most people stayed at home due to the coronavirus pandemic, we have prepared some educational presentations for children with ages below 14 to dive in-depth into astronomy topics. These series of presentations include videos, interactive games and a lot Read More …

#AthenaNuggets: Extrasolar planets: a radiation diet, by Jorge Sanz

June 17, 2020June 17, 2020 Ektoras PouliasisShort article

In #AthenaNuggets 40, Jorge Sanz talks about the relationship between the emission of X-rays by a star and its exoplanets. The role of the X-rays is fundamental to understand the phenomena of erosion in exoplanet’s atmospheres. The sensitivity of Athena Read More …

First optical measurements of Milky Way’s Fermi Bubbles probe their origin

June 16, 2020 Ektoras PouliasisArticle

Using the Wisconsin H-Alpha Mapper telescope, astronomers have for the first time measured the Fermi Bubbles in the visible light spectrum. The Fermi Bubbles are two enormous outflows of high-energy gas that emanate from the Milky Way and the finding Read More …

A New Galactic Center Adventure in Virtual Reality

June 14, 2020June 14, 2020 Ektoras PouliasisArticle

A new visualization, “Galactic Center VR,” features simulations of material streaming toward the Milky Way’s supermassive black hole, Sagittarius A*. Experience the last 500 years of cosmic evolution in this area in a free virtual reality program. This free program Read More …

‘Heart’ Of Black Hole Still Beating

June 14, 2020June 14, 2020 Ektoras PouliasisVideo

The first confirmed heartbeat of a supermassive black hole is still going strong more than ten years after first being observed. X-ray satellite observations spotted the repeated beat after its signal had been blocked by our Sun for a number Read More …

#AthenaNuggets: Tracing the expanding universe with quasars, by Elisabeta Lusso

June 14, 2020June 14, 2020 Ektoras PouliasisShort article

#AthenaNuggets 42 proposes the study of quasars as new cosmic tracers. These astronomical objects will allow the measurement of the expansion rate of the Universe up to z~10, i.e., when the Universe was less than 500 million years old. The role Read More …

#AthenaNuggets: The hunt for super-Eddington accretion flows in ultraluminous X-ray sources, by Ciro Pinto

June 14, 2020June 14, 2020 Ektoras PouliasisShort article

Ultraluminous X-ray sources (ULXs), the most extreme among binary stars, can aid us to face the following question: how many black holes managed to grow up to 10 billion Solar masses in less than a billion years after the Big Read More …

‘Heart’ Of Black Hole Still Beating After 10 Years

June 11, 2020 Ektoras PouliasisArticle

The first confirmed heartbeat of a supermassive black hole is still going strong more than ten years after first being observed. X-ray satellite observations spotted the repeated beat after its signal had been blocked by our Sun for a number Read More …
