Out today: Ultra-low frequency @LOFAR spectral indices of cluster radio halos led by @ThomasPasini94 w @roxycas @and_botteon @hen_edler et al. Main result: more massive clusters host flatter-spectrum halos arxiv.org/abs/2406.12005

Ultra-low frequency LOFAR spectral indices of cluster radio halos

A fraction of galaxy clusters harbor diffuse radio sources known as radio halos. The currently adopted scenario for their formation is based on second-order Fermi re-acceleration of seed electrons...

Our paper on Virgo Cluster AGN, lead by Hamburg student Angelina Spasic, was accepted today! This includes an analysis of the infalling giant elliptical M49, where we discovered a stunning superposition of the western radio and X-ray tail. --> arxiv.org/abs/2406.00781

Paper day! Our paper on decameter calibration has just been published in Nature Astronomy: nature.com/articles/s41550-0…

Characterization of the decametre sky at subarcminute resolution

Nature Astronomy - Decametre radio observations are challenging due to the presence of the ionosphere. Here Groeneveld et al. present a strategy to correct for the ionosphere that allows them to...

LOFAR is now officially an ERIC (European Research Infrastructure Consortium)! The LOFAR station of @unihh together with @unibielefeld is located just north of Hamburg in the city of Norderstedt. Congratulations to everyone who made it possible. @HambObs
Universität Hamburg@unihh22 Jan 2024
Das @LOFAR ist das größte Radioteleskop für den Empfang von Radio- und Ultrakurzwellen. Mit der @unibielefeld betreibt die UHH ein Antennenfeld in Hamburg-Norderstedt. Nun soll eine Trägereinrichtung für noch tiefergehende Radiobilder des Universums sorgen.uni-hamburg.de/newsroom/pres…

We just sent a letter to the EAS president informing them about a mistake in their carbon account that allowed them to ignore 99% of their emissions (namely that of the EAS Annual Meeting).

Paper day! We used LOFAR to observe the nearby Virgo cluster at unprecedented sensitivity. We detected >100 cluster member galaxies and measured their radio properties. The catalog as well as the images are available online at lofar-surveys.org/virgo_data…. arxiv.org/abs/2306.04513

Germany is basically the only country in the world without a speed limit. We wondered: is this economically justified, for example to save travel time? Read the results here: The economic cost of a 130 kph speed limit in Germany. doi.org/10.1016/j.ecolecon.2…

Wochenendtipp 📅 Sterne beobachten, Raketen basteln und Live-Musik: Der Tag der offenen Tür im @HambObs bietet vielseitiges Programm für Kinder und Erwachsene. Los geht es am Samstag ab 14 Uhr. Der Eintritt ist frei. Mehr Infos: uhh.de/4dsoe
Zu sehen ist ein Kuppelgebäude der Hamburger Sternwarte. Um das Gebäude herum stehen Bäume. Die Blätter sind bereits herbstlich gelb und orange gefärbt.
