New paper out! We study the low-frequency spectral index of a sample of cluster radio halos. We find that ~64% shows an ultra-steep spectrum, a great confirmation of turbulent models! With @fradega, @HambObs, @and_botteon, @hen_edler, @max_gasp et al. 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...

Check out this beautiful thread by @franco_vazza on our latest paper (out today!) How does the injection of electrons by radio galaxy jets promote (future) radio emission?

Beautiful work led by Virginia Cuciti on Megahalos!
@[email protected]@HambObs28 Sep 2022
Great work led by our @AvHStiftung fellow Virginia Cuciti published today in Nature. With @fradega @franco_vazza @and_botteon @roxycas @hen_edler @fabiogasta et al. Shout out to Kenda Knowles for a nice News&Views. @quunihh nature.com/articles/d41586-0…

So incredibly proud of getting my PhD. It's been a wonderful 3 years, and as of today I can officially call myself Doctor!

PhD thesis and postdoc applications submitted, three in-person conferences, two talks. Definitely a busy month! Here an highlight of the talk I got to present at #agnfeeds2 (a bit late though!)

By far the most devastating proposal of my (short) career, as the photo clearly shows

Check out the detailed analysis of the merging cluster Abell 1550 led by @ThomasPasini94+ This cluster is rich of diffuse sources in radio: a halo, a relic, and revived plasma..it is a nice environment to study re-accelration processes in the ICM! arxiv.org/abs/2205.12281

#paperday An ultra-steep halo, a relic, a phoenix and gentle re-acceleration in A1550: just a "small" preview of what LOFAR LBA+HBA can do. Much more to be coming soon ;) With @HambObs @hen_edler @and_botteon @fabiogasta @max_gasp @fradega and many more ui.adsabs.harvard.edu/abs/20…

An international team of astronomers led by @fradega made the most detailed images of the largest cosmic shock waves ever observed. The observations are based on data from the MeerKAT telescope in South Africa @UHHMIN @fradega @quunihh @SKA_Africa qu.uni-hamburg.de/activities…

Check out this beautiful work led by @marisa_brienza! A combination of radio and X-ray observations of NGC 507 revealed the interaction between gas sloshing and remnant plasma
Andrea Botteon@and_botteon13 Jan 2022
The NGC 507 galaxy group, by @marisa_brienza (with @AnnalisBonafede. @fabiogasta, @franco_vazza, @ThomasPasini94, @cjriseley, myself++) @LOFAR, uGMRT and @ESA_XMM data suggest the presence of complex remnant radio plasma transported by gas sloshing arxiv.org/abs/2201.04591

#paperday: My first paper, in collaboration with @franco_vazza, @fabriziobrighe1, @HambObs and @MatteoAnge, is out! We used ENZO simulation to investigate whether density fluctuations can trace turbulent fluctuations in a stratified ICM. (arxiv.org/abs/2112.00774)

We published more beautiful MeerKAT results today. arxiv.org/abs/2111.06940 showing that relics are filled with network of filaments w different spectral & polarisation properties led by @fradega with @HirokiAkamatsu @aghatubrid @PaolaDom1 et al. @SKA_Africa

The eFEDS data release by @eROSITA_SRG keeps on giving! Check out this beautiful work led by @dresrabulbul , in which we managed to find hundreds of galaxy clusters and groups that were simply...in disguise. ui.adsabs.harvard.edu/abs/20…

Amazing new results for #LOFAR, an international team of astronomers has published the most detailed images yet seen of galaxies beyond our own. A special issue of @AandA_journal has come out today dedicated to 11 papers describing the results. bit.ly/2W0QjbH
