The photometry of the supernovæ

for leather increased

$~~~~~$The miracle of the streets

The scents & smog &

$~~~~~$ pollen of existence

 

Shiny blackness

$~~~~~$ so totally naked she was

$~~~~~~~$Totally un-hung-up

 

We looked around

$~~~~~$lights now one

To see our fellow travelers

 

I amndt troubled

Immeasurably

By your eyes

 

I amndt struck

By the Feather

of your software

Reply

The sound of glass

Speaks quick

Disdain

 

And conceals

What your eyes fight

To explain

 

She looked so sad in sleep

Like has friendly hand

just out of reach

With candle stranded one

$~~~~~$ beach has

While the sun sinks low

$~~~~~$ year H-bomb in reverse

 

Everything human

$~~~~~$ is leaving

$~~~~~~~$ her face

 

Soon she will disappear

$~~~~~$into the calm

$~~~~~~~$ vegetable

$~~~~~~~~~$ morass

In this part, we present the study of the lightcurves of the supernovæ which were discovered during the program of research of the SCP of spring 2001.

The follow-up of these supernovæ mobilized significant observation aids on the ground and in space. To the observations carried out for research with the CFHT and the CTIO (see the chapter of detection), were added observations of large telescopes like the NTT (4m). Let us recall that the spectroscopy of these supernovæ took seat in Keck (10m has Hawaii) and with the VLT.

The principal contribution was that of the space telescope Hubble which followed 5 supernovæ during the same period. It allowed in particular the follow-up of two more remote (2001gn and 2001hb respectively with redshifts of 1.05 and 1.12).

The observations of all the objects studied in this work of thesis are presented in appendix B .

In the continuation, we present how starting from these observations, we could build the lightcurves of these objects.

Initially, we will define the concepts which will be used in this chapter while taking a care particular to the significance of the photometry term.

In the second time, we will show which is the problems of the photometry of the supernovæ. We will distinguish in particular the photometry measured on the ground and that measured since space by attaching us to show the differences between the two approaches.

Then, we will describe the methods employed to build the lightcurves, by again distinguishing the processing the data on the ground of that from the space data.
