Abstract:
We report the results of an [OIII] λ5007 survey for PNe in
five galaxies that were hosts of well-observed SNe Ia: NGC 524,
NGC 1316, NGC 1380, NGC 1448, and NGC 4526. The goals of this survey
are to better quantify the zero point of the maximum magnitude-decline
rate relation for SNe Ia and to validate the insensitivity of Type Ia
luminosity to parent stellar population using the host galaxy Hubble
type as a surrogate. We detected a total of 45 PN candidates in
NGC 1316, 44 candidates in NGC 1380, and 94 candidates in NGC 4526.
Description:
Our first observations were obtained on 2003 December 18-20 and 2004
November 11-12 using the Magellan Landon Clay telescope and the MagIC
camera. We supplemented our Magellan observations with additional data
obtained on 2005 March 10-11 using the WIYN 3.5m telescope and the
OPTIC camera.
