Research interests of the galaxy formation research group

Halo occupation models:

• Connection between the galaxies and the dark matter halos.

• Mock catalogues based on Conditional Luminosity Function (CLF) model.

• Constrain cosmological parameters using halo occupation model.

• Properties of the satellite galaxies.

Galaxy Groups and Clusters:

• Searching galaxy groups with a halo-based group finder.

• Searching galaxy clusters from photometric redshift surveys.

• Probe the halo-halo (group-group) bias from the observations.

• Measuring the halo occupations directly from the observations.

Cosmological weak lensing:

• Estimate the shear field, the lensing power spectrum.

• Probe the mass-light relation using numerical simulations/halo occupation model.

• To infer the mass-light relation from the galaxy-galaxy lensing signal.

• To infer the mass-light relation from the group-galaxy lensing signal.

Galaxy Formation and Evolution:

• Semi-analytical models.

• Numerical simulations.

• Understanding the galaxy formation and evolution using halo occupation models.

Large-Scale Structure of the Universe:

• Clustering properties of galaxies in large redshift surveys (i.e. 2dFGRS and SDSS).

• Traditional analysis:

  • 2PCF, 3PCF, power spectrum, bispectrum, etc.

• Discrete Wavelet Transform (DWT) analysis:

  • power spectrum, velocity field, redshift distortion, scale-scale correlation.

N-body and Gas Simulations:

• N-body simulations of structure formation.

• Gas simulations... to probe the properties of IGM
