An exciting map showing for the first time Bulgaria highlighted as part of the growing Low Frequency Array family! The STELLAR project is preparing the Bulgarian research community for developing its own LOFAR.BG station, science, and engineering. stellar-h2020.eu

LOFAR images of the Sun become more accurate; we start to reveal the details of the quiet Sun, fundamental in understanding how the corona is hotter than the solar photosphere. With LOFAR 2.0 we can study this using the LBA and HBA simultaneously. bit.ly/3a6KeAZ

Good demonstration of how some LEDs can cause problems for LOFAR.

A new STELLAR paper on solar radio emissions at the lowest radio frequencies observable from the ground just came out, led by Peijin Zhang 📡☀️!

Bulgaria joins the Low Frequency Array family!! #lofar22

My poster at #COSPAR2022 E2.4, very much welcome to come and have a quick chat or ask me anything in DM or comment

📜 Paper accepted √, it's a GPU accelerated method to derive the Quasi-Separatrix Layers (QSL), which could be used for the magnetic field topology analysis in solar active regions. FastQSL: arxiv.org/abs/2208.12569

Wow, here’s a satellite impacting an asteroid yesterday.

Hosting colleagues today from the STELLAR_H2020 project, ASTRON and Observatoire de Paris for more radio discussion DIAS Dunsink Observatory #PRE2022

New paper led by Dr. Corentin Louis from DIAS Astronomy & Astrophysics showing how we can observe Jupiter with ground-based radio telescopes including I-LOFAR. Comparing radio emission prediction tools against observations of Io-induced decametric emission. doi.org/10.1093/rasti/…

First ever imaging sequence of a solar eclipse at 50 MHz with Low Frequency Array!

The #LOFAR Science School has started! This week, 15 undergraduate and graduate students from Bulgaria and the region will learn about radio astronomy with LOFAR in Sofia. #radioastronomy

This morning we start with Pietro Zucca giving an overview of the Low Frequency Array telescope to the students. Check the full programme at stellar-h2020.eu/index.php/lofa…

Today Jeremy Rigney from DIAS Astronomy & Astrophysics is telling the students about transient radio signals on the sky, such as pulsars and fast radio bursts. Up next - what studies can be done with a single LOFAR station?

Today the students got treated to a visit of the #Discoverer petascale supercomputer, hosted at Sofia Tech Park. Bulgarian researchers already use this monster machine for processing of Low Frequency Array data!

📡 Radio waves from satellite constellations pose a threat to astronomical exploration. LOFAR confirms unintended emissions. Collaboration between astronomy and industry is vital, urging Int’l Telecommunication Union to regulate this emission. astron.nl/radio-waves-le… (Artist impression @DanielleFuts)

The final meeting of the STELLAR_H2020 project is underway in historic #Plovdiv!

Seeing first-light images of the Sun from the enormous Daocheng Solar Radio Telescope (DSRT) located in SW China CESRA Solar Radio and STELLAR_H2020 meetings in UK and Bulgaria this week. Built in only 3 years - amazing. Looking forward to seeing first-result papers Peijin Zhang 📡☀️.

The STELLAR_H2020 Final Meeting was a great success! From summaries of project achievements and discussions of how to strengthen our Low Frequency Array collaborations even further, to walks along historic old #Plovdiv's cobblestone streets, and a visit to the LOFAR.BG station site.
