How are giant elliptical galaxies formed in the early Universe? YouTube video by Nikolaus Sulzenauer

We also prepared a 1 min video summary: www.youtube.com/watch?v=NHph...

How giant galaxies could form just 1.4 billion years after the Big Bang Observations of the protocluster SPT2349-56 reveal how massive galaxies could form early in the Universe.

Paper day: I am extremely happy to announce our major discovery concerning the mysterious emergence of the first massive galaxies when the Universe was only 10% its current age:

Hi Svenja,
ich bin Doktorand der Astrophysik in Bonn und poste gerne auch auf Deutsch. Würde mich sehr freuen, zum Feed hinzugefügt zu werden! Meine ORCID: orcid.org/0000-0002-31...

Impossibly Hot Object Discovered 1.4 Billion Years After The Big Bang A 'shadow' cast on the faint, leftover glow of the Big Bang has revealed a giant object in the early Universe that defies our predictions of how the Universe should evolve.

That's one of the many press articles: www.sciencealert.com/an-impossibl...

What a great start into the new year. Prosit Neujahr!

Sunyaev–Zeldovich detection of hot intracluster gas at redshift 4.3 Nature - Detection of hot intracluster gas in SPT2349−56 with the Atacama Large Millimeter/submillimeter Array provides new insights into early cluster formation.

We found early Universe galaxies blowing scorchingly hot (~10 million Kelvin!) gas bubbles 🫧🔥

Congratulations to my colleague Dazhi Zhou at the University of British Columbia, and the rest of the SPT-SMG collaboration, for this astounding result!

🐦 Fly through a 3D map of stellar nurseries ✨

Scientists have created the most accurate 3D map of star-formation regions in our Milky Way galaxy, based on data from #ESAGaia.

The map extends to a distance of 4000 light-years from us, with the Sun at the centre 👉 www.esa.int/Science_Expl... 🔭 🧪

Hi everyone 👋 I am new here and want to share a few of my photos capturing the atmosphere of a summer day in Bonn, as seen by my camera in the near-infrared part of the spectrum🌈 Hope you like it!

I am currently perusing my PhD studies in astronomy and astrophysics and would like to be able to occasionally inform the astro community on bluesky about important or generally interesting findings within my field of expertise.
