This week’s Astrotweeps host is Gautham Narayan (@gsnarayan, http://www.noao.edu/noao/staff/narayan/). Gautham is an astrophysicist who likes stuff that blows up – explosive transients – particularly supernovae! He moved to the US in 2001 and got his BS in Physics at Illinois Wesleyan, where he worked with Prof. Linda French (@ispahan1) working on Jovian Trojans and Damocloids. From there he moved to grad school at Harvard University where he worked with Prof. Christopher Stubbs and Prof. Robert Kirshner. He got his PhD in Physics using type Ia supernovae from the ESSENCE and Pan-STARRS surveys to study the accelerating rate of expansion of the Universe, and the equation of state of the dark energy, w.
He began his post-doctoral career at the National Optical Astronomy Observatory (www.noao.edu) in Tucson, AZ, where he used the Hubble Space Telescope to establish a set of faint DA White Dwarfs as spectrophotometric standards for LSST and future surveys to address the largest source of systematic bias with SNIa cosmology surveys. These days, he works with the Computer Science department at University of Arizona on the ANTARES (Arizona-NOAO Transient Alert and Response to Events System) project, using machine learning techniques to characterize transients using their light curves, and identify the rarest, most interesting objects. He also works on education and outreach with the NOAO EPO office, and organizes Astronomy on Tap in Tucson (@space_drafts).
When he’s not sciencing, he’s hanging out with friends and his dog, Kepler, wandering town & listening to local musical acts, working on his photography (http://flickr.com/photos/gnarayan), hiking, and he’s known to get passionate about politics and equity in astronomy and society.
