About myself


I am Dr. Sambaran Banrjee, a theoretical astrophysicist, currently working as an independent researcher and a principal investigator at the Argelander-Institut für Astronomie and the Helmholtz-Instituts für Strahlen- und Kernphysik University of Bonn, Germany. I am born and grown up in Kolkata, India, where I went to school and completed my undergraduate studies.


I obtained my undergraduate education from the Presidency College (University), Kolkata with physics as the Major (B.Sc.). I joined the graduate school at the Tata Institute of Fundamental Research, Mumbai, India in 2001, where I did my Masters (M.Sc.) and the doctoral research work. I obtained my doctorate in August, 2008.


I joined the Argelander-Institut für Astronomie (AIfA) in Bonn, Germany in the same year with an Alexander von Humboldt (AvH) Fellowship (for postdoctoral researchers for two consecutive years). At present, I am a researcher (Wissenschaftlich Mitarbeiter) and as well a project principal investigator (PI) at the Bonn University.


Apart from my scientific activities, I also find interests in running, fitness, hiking, and cooking.



My main technical expertise lies in direct N-body simulations of stellar clusters, managing long runs (lasing up to months) of such computations, and managing and analyzing the simulation output data. In my work, I mainly use the state-of-the-art direct N-body code NBODY6/7 running on multi-CPU-multi-GPU platforms. In all the papers where I am the sole or first (and corresponding) author, I have done the N-body simulations, analyzed the simulation data, made the plots and the illustrations, organized and written the manuscript, and addressed the referee reports all by myself.
This is how I used to look like (a more recent picture coming soon!)






Description of the cover image:


Left panel: Star-burst region NGC 3603 (or the Giant Nebula) in our Milky Way galaxy as imaged by the Hubble Space Telescope. The central concentration of stars comprise a young (about a million year age), massive (about ten thousand times the mass of the Sun) star cluster. Such mammoth association of young stars are thought to be the progenitors of globular clusters that we find in numbers today in galaxies. The dimensions of this image are approx. 5 parsec. Image credit: NASA/ESA/HST.


Right panel: Globular cluster 47 Tucanae (NGC 104), one of the most massive (few million solar mass) and densest (spread over some 10 parsec) stellar systems in our Galaxy. Apart from the massive stellar population, a globular cluster like this host many neutron stars and black holes which can be seen as a number of pulsars and X-ray sources near its center. Mutual dynamical encounters among these closely-packed objects and with the normal stars can give rise to high-energy phenomena such as gamma-ray bursts and gravitational-wave emission.
