SPEX X-ray Spectral Fitting Package

We have released SPEX 3.08.02! The new version, among other things, features a new table model that can use Xspec formatted table models, like APEC and Xillver. The new version is available here: spex-xray.github.io/spex-help/ge...

How do galaxies evolve? Sometimes elliptical galaxies do not evolve like the majority of their type. This paper studies some massive compact relic galaxies, who managed to avoid collisions with their neighbours for a long while.

The deadline for the ACME call for visits to @sronspace.bsky.social is April 6th! If you are a researcher and want to visit us to learn about X-ray spectroscopy, please apply through the link below.

Proudly launching our new brand identity!

This modern identity marks the beginning of a new chapter for SRON as we continue our mission to advance space research and technology.

A new brand identity also means a brand-new website! Check it out: www.sron.nl

#newidentity #launchevent #sron

Our institute @sronspace.bsky.social has a new logo and website. And they are active now on Bluesky! Check it out!

There is a new opportunity for researchers to visit SRON and learn about X-ray spectroscopy. Your visit can be funded through the ACME Project. The deadline for submissions is April 6th 2025. More details about the program and other host institutes can be found here: acme.in2p3.fr/tna-calls-ce...

Hi all! We are the HEACIT working group, a collaboration between scientists and software engineers in the field of high-energy astrophysics. We aim to coordinate various aspects of data analysis and software development together to improve the use of our data analysis tools.

XMM-Newton celebrates 25 years of breakthroughs Today, ESA’s powerful X-ray observatory, XMM-Newton, celebrates 25 years in space. From planets to black holes, the space telescope has delivered many ground-breaking observations of a variety of cele...

Today, XMM-Newton celebrates it's 25 year launch day 🎂https://www.esa.int/Science_Exploration/Space_Science/XMM-Newton/XMM-Newton_celebrates_25_years_of_breakthroughs

An artist impression of the XMM-Newton telescope in space.

Tomorrow, it is 25 years ago that the #XMM-Newton X-ray observatory was launched by ESA. Amazingly, the satellite is doing great! It still performs observations of the X-ray universe, from the hot gas swirling into black holes to the hot gas in the cosmic web. Stay tuned www.esa.int/Science_Expl...

SPEX is moving away from X, but not from X-rays! Wishing everybody blue skies ☀️ and good space weather 🛰️ for X-ray observations. More about SPEX software: www.sron.nl/astrophysics...
