Wowowow! That was quick! These look incredible!

You can find a list of Christian's publications here: orcid.org/0000-0002-88...

Congratulations, Dr. Groeneveld!

Christian’s research focused on the Perseus galaxy cluster. They confirmed two giant structures: a radio "mini-halo" around the central galaxy, and a much larger "giant radio halo" over a million ly! These halos likely come from turbulence caused by past cosmic mergers, which re-energize particles.

Studying space at such low frequencies is incredibly challenging because the Earth's ionosphere distorts the incoming radio waves. Christian helped develop a new calibration technique that enables higher sensitivity and resolution imaging at these wavelengths.

These are great! I would put prints of a set up in my office.

This is so great 😍😍

Hi Bunny! What a fabulous idea - it would be an honour to collaborate. I'll DM you.

Aww thanks for the sweet words! I'm so happy you like my art. Yes, please repost with credit :-) 🙏

I was asked to give my social media accounts when applying for my work visa last fall.

I hope so too Susan. I think too often scientists try to remain applitical and (are told to) "stick to the science". I try to remember that science is (and has always been) political and we scientists are also (first and foremost) humans.

The pillars of creation were first made famous when imaged by the Hubble Space Telescope in 1995 (and again in 2014) in visible light - which I have previously painted. The near-infrared view from JWST helps us peer through more of the dust - revealing many more stars that are forming within.
