An international team of astronomers led by Francesco Dega of the Hamburg Observatory made the most detailed images of the largest cosmic shock waves ever observed.

Detailed images of a shock wave that extends for 6.5 million light years An international team of astronomers led by the Hamburg Observatory made the most detailed images of the largest cosmic shock waves ever observed. The observations are based on data from the MeerKAT radio telescope in South Africa and have been published in the journal Astronomy & Astrophysics.

New results from our scientists working with the new MeerKAT telescope (Francesco Dega Denis Wi Paola Domínguez Virginia Cuciti) - incredibly detailed images of a cosmic shock wave generated after the clash of two galaxy clusters.

The low-frequency radio group of the observatory of Hamburg helped preparing these incredible images of a black hole that gives shape to bubbles, rings and intergalactic smoke filaments!

LOFAR lastest discovery on exoplanets!

Aurorae discovered on distant stars suggest hidden planets Using the radio telescope LOFAR, scientists have discovered stars unexpectedly blasting out radio waves, possibly indicating the existence of hidden planets. The research was recently published in Nature Astronomy.

This weekend the Observatory in collaboration with Proxima (http://prox-ima.it) experimented with a novel type of outreach, mixing science, theater and live action role play. Play set in 1988. Lots of fun!

Anlässlich der partiellen ringförmigen Sonnenfinsternis am 10.06.2021 laden die Hamburger Sternwarte und der Förderverein herzlich ein, das Naturereignis direkt an der Sternwarte im Live-Stream mit zu verfolgen, eingerahmt in ein Programm aus vier astronomischen und kulturgeschichtlichen Vorträgen zum Thema Sonnenfinsternis.

Zum Ausklang gibt es ab 16 Uhr „Der Kleine Prinz“ als musikalische Lesung, dargeboten vom Tourneetheater Hamburg (Hutspende).

Die Vorträge und Darbietungen können auch einzeln besucht werden.

Einlass: Ab 10:00 August-Bebel-Straße 196.

Eine Teilnahme in Präsenz ist nach vorheriger Anmeldung und unter Beachtung der allgemeinen Abstands- und Hygieneregeln (Mund-Nasen-Schutz) möglich. Alle Veranstaltungen finden im Freien statt. Alles weitere dazu auch auf unserer Homepage.

Zusätzlich gibt es die Möglichkeit zur digitalen Teilnahme: ZOOM ID 631 0065 3984 - Kenncode: HS_@gw24

We have an open PhD position in the radio group the the university of Hamburg! The project revolves around the study of clusters and active nuclei at the lowest frequencies (deadline: May, 15th) :)

An international team of astronomers, led by Junior Professor Francesco de Gasperin, scientist at the Hamburg Obervatory and member of the Cluster of Excellence at Universität Hamburg, has produced the largest and sharpest map of the sky at ultra-low radio frequencies. The map published in the journal Astronomy & Astrophysics reveals more than 25,000 active supermassive black holes in distant galaxies.

**LIVE NOW** - our colleague Virginia Cuciti is talking at the ESO Hypatia Colloquium with a presentation titled: "Clash of Giants: radio emission from merging galaxy clusters"

Hypatia Colloquium

Clash of giants: radio emission from merging galaxy clusters! This is the title of the talk that our von Humboldt fellow Dr. Virginia Cuciti will give at the ESO Hypatia colloquium on Tuesday 2nd, February at 3 pm.

ESO - Program ESO is the European Organisation for Astronomical Research in the Southern Hemisphere. It operates the La Silla Paranal Observatory in Chile and has its headquarters in Garching, near Munich, Germany.

This beautiful image of the brightest radio sources, observed with LOFAR at 54 MHz by our colleagues in de Gasperin et al. (2020), made it on the calendar of Astronomy & Astrophysics
