Gaurav Goswami is an Assistant Professor at School of Engineering and Applied Science, Ahmedabad University. Before joining Ahmedabad University he was a postdoctoral fellow at Physical Research Laboratory (PRL), Ahmedabad. He obtained his PhD (Physics) in the field of theoretical cosmology from Inter-University Centre for Astronomy and Astrophysics (IUCAA), Pune.

His primary research interest is the interface of fundamental physics and cosmology.

Broad area of research:

The interface of cosmology and fundamental physics (high energy physics). Particularly,

  • Theoretical cosmology:
    • Main focus on cosmic inflation and its realisations in theories of high energy physics e.g. string theory,
    • Other subjects at the interface of cosmology and high energy physics e.g. baryon asymmetry of the universe, dark matter, dark energy, neutrino masses; physics beyond the standard model of elementary particle physics;
  • Cosmological probes of fundamental physics: Cosmic Microwave Background (e.g. current and near future constraints on inflationary observables), Gravitational Waves.

  • Computational cosmology: Cosmic Microwave Background data analysis.

Specific research directions:

  • Past:
    • Classical and quantum dynamics of cosmological perturbations (1011.4914, 1307.4735, 1406.6352)
    • Constraining properties of viscous dark matter from gravitational wave observations (1603.02635), 
    • Using observations of temperature anisotropies of CMB to reconstruct Primordial Power Spectrum (1303.4747), 
    • An attempt to resolve the Higgs vacuum stability problem (1406.5644),
    • The observational constraints on a pre-inflationary radiation dominated era (1412.7093, 1506.04808), 
    • The observational constraints on warm inflation (1710.11109),
    • New models of elementary particle physics to explain collider signals as well as their implications for cosmology (1512.06782),
    • Observational constraints on models of cosmic inflation involving extra dimensions of space which attempt to resolve ultraviolet sensitivity of inflation (1705.11071);
  • Current:
    • Cosmological solutions in string theory e.g. swampland and related conjectures e.g.
      • Attempting to find string theoretic realisation of large field excursions (1812.11909),
      • Consequences of trans-Planckian censorship conjecture on moduli dominated cosmology (1910.06233),
      • Warm inflationary models which are consistent with swampland distance conjecture, refined swampland conjecture and trans-Planckian censorship conjecture (1911.00323).
    • Axions and axion like particles, their possible role in structure formation, and novel ideas for detecting them,
    • Other issues in cosmology e.g. dark energy, neutrino masses, baryon asymmetry of the universe, dark matter; moduli cosmology;
