PI: Dr. Peter Milne University of Arizona CoI: Dr. Jesper Sollerman Stockholm University N CoI: Prof. Claes Fransson Stockholm University N CoI: Dr. Cecilia Kozma Stockholm University N ------------------------------------------------------------------------------------ Abstract A better understanding of the physics of Type Ia supernovae (SNe) is important for their use as cosmological standard candles. Late time observations of the SN light curves are poorly studied - but offers a unique way to probe the explosion models. Combining state of the art models of 3-D explosions with sophisticated spectral modeling, we can test these models against observations in a way not earlier possible. In particular, the broad band light curves are sensitive to the degree of clumping and the timing of the `infra-red catastrophe', factors which depend on the explosion mechanism (deflagration vs. delayed detonation). Further, these observations can probe the degree of positron trapping in the ejecta, important for both the SN ejecta and for the production of free positrons in the galaxy. Because of its small distance, favorable galaxy location and excellent ground based follow- up - SN 2003hv offers a unique opportunity to obtain the best late light curves to date. Observations in several optical and IR bands will enable us to distinguish between different model predictions. ------------------------------------------------------------------------------------ 10513( 4) - 10/10/05 08:27 - [ 2] Observations Description ------------------------ We propose to observe SN 2003hv over seven (7) orbits, employing the ACS and NICMOS instruments. The predicted magnitudes and exposure times needed for each band are shown in the following table. These observations are requested to occur between the dates of November 1, 2005 and December 10, 2005. Roughly one orbit per band is requested using ACS to detect the SN in the B, V, and I bands, while four orbits are requested using NICMOS to detect the SN in the H band. During the course of the NICMOS observations, we propose to dither about the target in a square pattern with Small Angle Maneuvers of 1".

It is important for the goals of this proposal that the observations are made more than 800 days after the explosion, but not so late that the supernova is too faint to detect. The optimal window is thus November 1, 2005, through December 15, 2005.
