Welcome to homepage of Kishalay De
I am a fifth year graduate student in the Department of
Astrophysics at the California Institute of Technology. I am
working with my advisor Mansi
Kasliwal on optical and infrared transients in the local
universe, using the Palomar Gattini-IR and Zwicky Transient
Facility time domain surveys as discovery engines.
For my thesis, I am using demographics of transients in the local universe as probes of the formation and fates of compact objects in binary systems. I lead the Palomar Gattini-IR survey (De et al. 2020a), focusing on obscured large amplitude transients (such as classical novae) in the Galactic plane (De et al. 2020c, De et al. 2021b). With the optical time domain group at Caltech, I lead the Census of the Local Universe Experiment of the Zwicky Transient Facility (De et al. 2020b) to study large samples of low luminosity transients in the local universe that may arise from compact objects in accreting close binary systems (De et al. 2018a, De et al. 2018b, De et al. 2019, De et al. 2021a). Here is a complete list of my publications.
I grew up in the city of Kolkata, India. I obtained my undergraduate degree in Physics from the Indian Institute of Science in Bangalore, India. For my undergraduate thesis, I worked with Yashwant Gupta and Prateek Sharma on developing GPU-based signal processing pipelines for the pulsar back-end of the Giant Metrewave Radio Telescope. High time resolution studies of radio pulsars with these pipelines (De & Gupta 2016) led to the first detection of microstructure emission in millisecond pulsars (De et al. 2016), and now forms the core of the Indian Pulsar Timing Array experiment (Joshi et al. 2018). Previously, I also worked with Kirpal Nandra and Gabriele Ponti at the Max Planck Institute for Extraterrestrial Physics (as DAAD-WISE fellow) on the secular evolution of low mass X-ray binaries (Ponti, De et al. 2017).
