Kanan Kumar Datta

Assistant Professor

I am a UGC Assistant Professor at the Physics Deperatment, Presidency University, Kolkata.  The broad topic of my research is Astrophysics and Cosmology. In particular, we are trying to understand one of the landmark events in the early universe i.e, the cosmic dawn and epoch of reionization. The key questions that we are trying to find answers to:

1. when did first stars, galaxies, black holes appear in the universe?

2. how did they look like ?

3. how exactly did the reionization of universe take place ?

The cosmic dawn and reionization of universe is often regarded as one of the last frontiers of modern cosmology and astrophysics. Observations of 21-cm signal from neutral Hydrogen will provide detailed picture of the cosmic dawn and reionization epochs. I am involved in modelling the HI 21 cm signal that is expected to come from the early Universe, developing detection techniques and bridge the gap between observations and theory. Apart from that, I work on cross-correlations of the HI 21 cm signal with CMBR, Lyman- alpha, Lyman Break Galaxies to understand the post reionization universe.

I am also actively involved in "Cosmic Reionization group in India". See here for details of the group activities.
