Dr. rer. nat. Dhanya G. Nair

Dhanya is from Kerala, India. She completed her Ph.D. at the Max-Planck Institute for Radio Astronomy (MPIfR) in Germany with β€˜magna cum laude (1.0)’. Her thesis was titled "Global Millimeter VLBI Array Survey (GMVA) of Ultracompact Radio Sources at 86 GHz" in which she imaged the regions as small as 1000-10000 Schwarzschild radii of the central supermassive black holes in 174 AGN using VLBI techniques (for more details: here ).

After her Ph.D., she worked as a support scientist for the European VLBI Network (EVN) at the Joint Institute for VLBI ERIC (JIVE) in the Netherlands.

Currently, Dhanya is an Event Horizon Telescope (EHT) postdoctoral fellow working with Dr. Neil Nagar. She holds an independent Fondecyt postdoctoral fellowship for the project titled β€˜The Event Horizon and Environs Sample: beyond SgrA* and M87’. Her research focuses on identifying, observing and imaging a definitive sample of nearby AGN in which EHT (and ngEHT) can potentially resolve the black hole shadows and/or the jet base at <100 gravitational radii.

She is a member of the EHT and ngEHT collaboration, which aims to image the black hole shadows in M87, SgrA*, and several AGN observed with the EHT. She is actively involved in the data calibration (using the CASA rPICARD pipeline) and polarimetric imaging (with ehtim) of the M87 galaxy from 2021 EHT observations. She is also a member of the Low-Frequency Array (LOFAR) collaboration, which aims to conduct deep radio surveys to understand the formation and evolution of galaxies, clusters, and AGN.

Research interests & expertise:

  1. Acceleration and collimation of relativistic jets in AGN
  2. High-frequency very long baseline interferometry (GMVA, EHT)
  3. Restarted radio galaxies in Low-Frequency Surveys, particularly with LOFAR telescope
  4. EHT polarimetric imaging of M87
  5. Resolving the radio cores of the Quasar Feedback Survey sample with EVN+e-MERLIN
  6. Testing AGN evolution and feedback in the Lockman hole by combining the LOFAR telescope and e-MERLIN/EVN
