Priyamvada Natarajan

Priya Natarajan is a theoretical astrophysicist interested in cosmology, gravitational lensing and black hole physics. Specific questions that her work addresses are:

Cosmology

• Substructure in cosmological models
• Evolution and assembly of clusters
• Cosmological constraints from clusters and lens statistics
• Gamma-ray bursts as cosmological probes
• Mapping dark matter
• Probing the nature of dark energy with cluster strong lensing
• Black Hole seed formation at high redshifts
• Mass assembly history of black holes
• Alignments of black hole spins
• Black hole accretion
• Warped accretion disks
• High redshift pre-galactic disks
• Direct formation of black hole seeds
• Feedback processes: energy input from AGN and Supernovae
• Issues in epistemology
• Philosophy of Cosmology
