MMA Winter Science Speaker Series: Tanveer Karim
"Unraveling the Universe with Spectroscopy and Big Data"

The Dark Energy Spectroscopic Instrument (DESI) is an upcoming cosmological survey and experiment that will create the most precise 3D map of the Universe to-date by mapping the positions of 30 million galaxies spanning the past 11 billion years. By precisely measuring the position of these galaxies, DESI will try to shed light on the mysterious Dark Energy, the leading explanation for the accelerated expansion of the Universe, as well as test Einstein’s Theory of Relativity at the largest scales. In this talk, I will be discussing what dark energy is, how DESI works, how we plan to measure distances of such a large number galaxies, and what interesting sciences we can expect over the next ten years. In particular, I will be discussing how I am using DESI data along with cosmic microwave background (the earliest relic light of the Universe) data to figure out how matter is distributed in our Universe.

Bio: Tanveer Karim is a 4th year PhD student and a National Science Foundation Graduate Fellow at Harvard University working on the Dark Energy Spectroscopic Instrument (DESI) experiment. Tanveer’s dissertation work focuses on using a type of galaxy called emission-line galaxies to study the distribution of matter in the Universe and measuring cosmological parameters that can help us test different cosmological theories.

Prior to this, Tanveer completed his BS in Physics and Astronomy at the University of Rochester in 2017. He was also an MMA intern in 2016 studying and characterizing the Fermi Bubbles and he subsequently published two papers on this project. He also enjoys science outreach activities and mentoring students interested in astronomy. Outside astronomy, he enjoys reading and learning languages.
