OFFER DESCRIPTION

Join a vibrant research group in revealing the processes that govern solar eruptions and the acceleration of solar energetic particles. Explore rich datasets of low-frequency solar radio imaging observations. Develop state-of-the-art machine learning and deep learning models for automated processing of large radio data and characterising eruptive features with unprecedented detail. Help develop a professional radioastronomical observatory!

The research group of Prof. Kamen Kozarev at the Institute of Astronomy and National Astronomical Observatory (IANAO) of the Bulgarian Academy of Sciences is looking for a postdoctoral researcher to work on processing and analysing advanced low-frequency radio imaging observations of solar coronal shocks and coronal mass ejections from the Low Frequency Array (LOFAR) and Murchison Widefield Array (MWA) low-frequency telescopes. The two-year full-time position is available starting on November 1st 2021, or soon thereafter, and can be extended for an additional year. A very competitive salary and ample conference travel funds are offered. Applications will be reviewed on an on-going basis.

The postdoctoral researcher's term will coincide with the EU-funded STELLAR project (http://lofar.bg/stellar), focused on developing a strong radio astronomy community in Bulgaria via a training and research visits programme led by The Netherlands Institute of Radio Astronomy (ASTRON) and the Dublin Institute of Advanced Studies (DIAS). The successful candidate will benefit from this educational and collaboration opportunity.

The postdoctoral researcher will join Dr. Kamen Kozarev and his research group to study the dynamic features of solar eruptions and time-dependent spectra of energetic electron beams in the corona. The researcher will help develop and employ processing pipelines for solar interferometric observations. These data can reveal the locations of charged particle acceleration with great spatial, temporal and frequency resolutions. While such observations have traditionally been challenging, new advanced approaches, together with improved computing technology and software, have made them more accessible for routine investigation of solar activity. Available synergistic EUV and in situ data (from Parker Solar Probe and Solar Orbiter) will also be analyzed.

 

Requirements:

Applicants must hold a PhD in physics, astronomy, or astrophysics, with a focus in radio astronomy, heliophysics, or a closely related field. Previous experience in scientific programming in Python, Sunpy, CASA or similar, Linux/Unix environments, version control (svn, git), and work on building processing pipelines will be considered an advantage.

How to Apply:

Interested candidates should contact Dr. Kamen Kozarev (kkozarev@astro.bas.bg):

1) arrange for two letters of recommendation to be sent to him, and provide

2) a cover letter describing their experience and research interests,

3) a curriculum vitae,

4) a list of relevant publications.

Additional Information:

The position is part of the 5-year CAREER-type project ”Modeling and ObServAtional Integrated Investigations of Coronal Solar Eruptions” (MOSAIICS), funded by the National Science Fund of Bulgaria. The project is led by Assoc. Prof. Kamen Kozarev.

The overall goal of the MOSAIICS project is to adopt an integrated approach providing a deeper understanding of the plasma processes leading to charged particle acceleration by CMEs near the Sun. The project’s high level objectives are to (i) develop and integrate novel image processing and machine learning techniques to reliably analyse radio and EUV remote imaging observations of CMEs and their shocks; (ii) investigate the origins and evolution of radio emission from energetic electron beams in CMEs, comparing with in situ measurements; (iii) develop and apply advanced global data-driven models of particle acceleration and transport to test and improve our theoretical understanding of SEP production and transport. This postdoctoral position will focus on the second objective.
