Dr. Maryam Arabsalmani (ORIGINS Vera Rubin Fellow)

I am an observational astronomer. I did my Ph.D. jointly at European Southern Observatory (ESO) and Dark Cosmology Centre, Niels Bohr Institute, Copenhagen University. Thereafter I continued my research as a Postdoctoral Fellow at CEA Paris-Scaly, and as an ASTRO 3D Research Scientist jointly at the University of Western Australia and the University of Melbourne. At the moment I am working at the the Excellence Cluster Origins as a Vera Rubin Fellow.

Rather than astronomy, I enjoy cooking, going for long walks, and having long chats with my friends over a cup of tea. But what I enjoy the most is looking at paintings, listening to music, and watching good movies.

My research

My main interest is unveiling the physical conditions required for the formation of Gamma Ray Bursts (GRBs), Superluminous supernovae (SLSNe), and Hypernovae (HNe). These rare events are the violent explosions of very massive stars in the hearts of star forming regions and are observed out to very high redshifts. These energetic transients not only are valuable laboratories for extreme physical conditions, but also are powerful tracers of fundamental processes in galaxy formation. Thus they open an independent window into addressing the unresolved issues in galaxy formation and evolution. Although significant and concerted efforts invested over the past decades have brought valuable insights, our knowledge of the true nature of these rare events remains elusive. Revealing the characteristics of the progenitor stars giving rise to these bright events and the physical conditions in which they form will significantly advance the field of transient astronomy and will have strong impacts on the fields of galaxy formation and evolution, cosmology, stellar evolution, and massive star formation.
Over the past few years, I have been leading a large project for detailed studies of the distribution and kinematics of gas components, the main tracers of galaxy dynamics, in the explosion sites and over galaxy scales. These studies have proven to be essential for addressing the outstanding questions on conditions required for formation of massive star explosions. I have also carried out projects for utilising these energetic explosions to address the core issues in galaxy formation and evolution which cannot be addressed otherwise.

I use multi-wavelength observations obtained by optical, mm, and radio telescopes. These include The Very Large Telescope (VLT), The Atacama Large Millimeter Array (ALMA), The Karl G. Jansky Very Large Array (JVLA), The Giant Metrewave Radio Telescope (GMRT), and MeerKAT.
