About me

Hi I'm Martyna

I am an independent research fellow at the Max Planck Institute for Astrophysics (MPA) in Garching, Germany. My research connects the evolution of massive stars and binaries with chemical evolution of the Universe. I combine both topics in the context of gravitational wave astrophysics. I obtained a cum laude doctoral degree at the Radboud University. In 2020, I have been distinguished with a Christine Mohrmann Grant, awarded to ten female PhD researchers from all disciplines by the Radboud University. In 2022, my PhD thesis has been distinguished with a honourable mention by the Galaxies and Cosmology Divison of the International Astronomical Union and by the GWIC-Braccini Thesis Prize Committee (for research in gravitational wave related areas).

I am a member of the ENGRAVE, LISA and the Einsten Telecsope collaborations. You can read more about my scientific interests below or in this short article in which I was featured as part of the "meet MPA fellows" series. I love figure skating (both on ice and inlines), but enjoy doing (almost) any other sport too.

My family name (Chruślińska) tends to scare people - before you give up, try reading it as: Hroo-shlin-ska (assuming standard English pronunciation).

With gravitational wave detectors, we are now routinely observing merging black holes and neutron stars. Those are the afterlives of massive stars that formed all across the Universe. Their mergers carry information about the way stars and galaxies form . They are unique probes of stellar evolution in galaxies that are very different from our own. This information could be deciphered by comparison with the models, provided that the uncertainties involved in the modeling are well understood.
My work shows that the outcome of the modeling is strongly affected not only by the description of the formation of mergers, but also by the assumed amount of elements heavier than helium with which the stars are born. Those elements are produced in stellar interiors and gradually released to the surrounding medium, where the new stars can form. I use observational properties of star forming galaxies to understand how the abundance of those elements changes with the next generations of stars forming over time. This is crucial for the correct interpretation of the properties of the populations of gravitational wave sources observed with current and future detectors.

Teaching & Outreach

I have been working as a teaching assistant at the Radboud University for a number of courses:
  • Stellar evolution (academic years 2017/2018, 2018/2019, 2019/2020)
  • Interstellar medium (academic years 2017/2018, 2018/2019, 2019/2020)
  • Programming in Python (academic year 2018/2019)
  • Galaxies (academic year 2017/2018)
I was also involved in the organisation of the Dutch Astronomy Olympiad (Nederlandse Sterrenkunde Olympiade) in 2019 in Nijmegen.
I am a member of the the Almukantarat Astronomy Club - a non-profit organization based in Poland, whose main goal is popularisation of science, in particular astronomy among young people. I have been a volunteer lecturer during the summer astronomy camps for the high school students organized by the Club in 2012,2013,2014,2015,2017 and 2018. I've co-organized one of the spring meetings on behalf of the Club and was a member of the Club's board in 2015-2017.

I was the President of the Students Astronomy Association (KNAstr) at the Warsaw University (Jan. 2013 - Oct. 2015), organizing the weekly meetings, a number of outreach activities for both general public and the members of the Faculty of Physics, as well as the student's astronomy conference in the beautiful Izera Dark-Sky Park in April 2015.
