RESEARCH INTERESTS

My primary research area are supernova remnants. A supernova explosion marks the endpoint of a massive star evolution, resulting in an expanding shell, the supernova remnant (SNR), followed by slower moving stellar ejecta. The input of energy and freshly produced heavy elements into the interstellar medium make SNRs, dynamically and chemically, one of the most important objects in galaxies.

Life cycles of stars Image credit: Life cycles of stars from NASA's Imagine the Universe . The bottom diagram shows evolution of a normal mass star, like our Sun: the star is burning its fuel slowly, and towards the end of the life goes through a red giant phase, ending its life as a white dwarf, and then brown dwarf. The upper diagram shows the evolution of a massive star: the star is burning its fuel more rapidly, goes through a supernova stage and explodes, creating a supernova remnant shell that dissipates back into interstellar medium. The supernova explosion can also leave behind a compact stellar core, a neutron star or a black hole.

Current research interests:

  • gamma-ray emission and particle efficiency in old SNRs (see e.g. Abdo et al 2010, Science, vol. 327, page 1103);
  • origin of overionised plasma in mixed-morphology SNRs (see e.g. Yamaguchi et al. 2009, ApJ, vol. 705, page L6);
  • study of stellar nucleosythesis via SNR ejecta and link with SNR shocks and dust destruction in the interstellar medium (see e.g. Lee et al. 2010, ApJ, vol. 711, p. 861);
  • study of new class of neutron stars named 'compact central objects' that oppose to the standard scenario for neutron star creation (see e.g. Gotthelf et al. 2010, ApJ, vol. 709, page 436);
  • broad-band emission of pulsar wind nebulae and their evolution inside the SNRs (see e.g. Pellizzoni et al. 2010, Science, vol. 327, page 663);
  • plasma properties of filaments in galaxies (see e.g. Fraser et al. 2011, MNRAS).
