RESEARCH FOCUS-Physical Cosmology
Current main research activities of my team:Late Universe and Dark Energy
- Reconstruction of the expansion history of the Universe and growth of structure
- Falsifying different aspects of the standard model of cosmology
- Cosmology with strong lens systems
- Cosmology with gravitational waves (bright and dark sirens)
- Dark energy modeling.
- Testing isotropy and homogeneity of the Universe using different cosmological observations (CMB, galaxy distribution, low-z SN Ia, GRBs, etc).
- Probing systematics in cosmological data through model-independent consistency checks.
Early Universe Scenarios and Primordial Power Spectrum
- Reconstructing the primordial spectrum using CMB and large scale structure data
- Inflationary scenarios
- ISW and connecting late and early universe.
Advanced Statistical Techniques
- Crossing Statistics
- Iterative method of smoothing
- Deconvolution methods such as Modified Richardson-Lucy algorithm
- Gaussian Processes
Astrophysics
- Reconstructing the internal dynamic of the galaxies (rotation curves)
- Supernovae light curve analysis using Gaussian processes and cross-correlation
- Time-delay estimation in strongly lensed systems (supernovae and quasars)
- Resolving unresolved strongly lensed systems (supernovae and quasars)
Collaborations
- DESI (Dark Energy Spectroscopic Instrument)
- Rubin Observatory (LSST)
