Sullivan, M., Ellis, R. S., Aldering, G., Amanullah, R., Astier, P., Blanc, G., ...
(Abridged) We present new results on the Hubble diagram of distant type Ia supernovae (SNe Ia) segregated according to the type of host galaxy. This makes it possible to check earlier evidence for a...
The SNAP near infrared detectors (2002)
Tarle, G., Akerlof, C., Aldering, G., Amanullah, R., Astier, P., Barrelet, E., ...
Overview of the SuperNova/Acceleration probe (SNAP) (2002)
Aldering, Gregory L., Akerlof, C.W., Amanullah, R., Astier, P., Barrelet, E., Bebek, C., ...
Wide-field surveys from the SNAP mission (2002)
Kim, Alex G., Akerlof, C.W., Aldering, G., Amanullah, R., Astier, P., Barrelet, E., ...
Cosmological parameters from lensed supernovae (2002)
Goobar, A., Mortsell, E., Amanullah, R., Nugent, P.
We investigate the possibility of measuring the Hubble constant, the fractional energy density components and the equation of state parameter of the ``dark energy'' using lensed multiple images of...
SNOC: a Monte-Carlo simulation package for high-z supernova observations (2002)
Goobar, A., Mortsell, E., Amanullah, R., Goliath, M., Bergstrom, L., Dahlen, T.
We present a Monte-Carlo package for simulation of high-redshift supernova data, SNOC. Optical and near-infrared photons from supernovae are ray-traced over cosmological distances from the simulated...
Correcting for lensing bias in the Hubble diagram (2002)
Amanullah, R., Mortsell, E., Goobar, A.
Gravitational lensing will cause a dispersion in the Hubble diagram for high redshift sources. This effect will introduce a bias in the cosmological parameter determination using the...

Supernovae and the Nature of the Dark Energy (2001)
Goliath, M., Amanullah, R., Astier, P., Goobar, A., Pain, R.
The use of Type Ia supernovae as calibrated standard candles is one of the most powerful tools to study the expansion history of the universe and thereby its energy components. While the analysis of...
