This topic will take you for a quick walk through the Universe. One of the important challenges in cosmology is to explain the formation of structure in the Universe. More than 30% of the ultraviolet and optical light from the stars and galaxies in the Universe may be absorbed and reradiated thermally at infrared and millimeter wavelengths by the obscuring dust. The cool and dusty sites in the Universe provide seeds for the formation of molecules and organic compounds. These molecular clouds are actually stellar nurseries which give rise to star formation and its evolution. To study dust extinction and its properties, among various structures, the highly energetic, Gamma-ray burst afterglows are excellent probes. This topic will cover that what we know about cosmic dust and how do we study it.
I was born and brought up in Pakistan. I did my masters in Physics from there. After masters my fascination to astronomy kept on going and I started reading books and looking things online. Later I applied for PhD positions in astronomy and after an interview and a written test I got selected by the University of Copenhagen Denmark for a PhD. After my PhD, I worked in Marseille France as a Postdoc and then later joined as a postdoc fellow at the European Southern Observatory, Germany. This gave me opportunity to work with the world class 8meter telescopes in Chile. I recently moved to Australia and presently working at the Australian Astronomical Observatory and continuing staring the vast heavens.
My research is mainly focused on studying gas, metals and dust in the interstellar medium of distant bright galaxies, mostly through Gamma-ray bursts, quasars and their intervening absorbers.
