Determination of Hubble Constant Using Apparent Magnitude and Redshift of Type-I Supernovae

The Hubble constant is a very important constant in cosmology which measures the mean expansion rate of the universe. In this paper, we obtain a non-linear relationship between apparent magnitude and redshift of type Ia supernovae (SNe Ia). Using this relation we determine the Hubble constant H-0 = 63.13 +/- 6.48 km/s/MPc.
