Description
Type Ia supernovae (SNe Ia) are thermonuclear explosions resulting from white dwarfs that have exceeded the Chandrasekhar limit of 1.44 solar masses.
In near-infrared (NIR) wavelengths, these SNe are nearly standard candles even before correcting for light-curve shape and reddening, and can with high precision be used as distance estimators to their host galaxies.
In this talk, I will describe some of the techniques we use to determine the brightness of a SN in the local Universe at redshifts less than 0.1.
This includes how the raw telescope images are processed, how we determine the brightness of the SN at a given epoch, determination of the peak brightness of the SN and constructing a Hubble diagram.
