Constraints on the gamma-ray emission of SN 2011fe after the maximum of light as obtained by INTEGRAL/SPI
Abstract
SN2011fe (RA = 14:03:05.81, Dec = +54:16:25.4; J2000) is a Type Ia supernovae that was discovered in M101 on August 24th 2011, by the Palomar Transient Factory (Nugent et al, ATEL #3581) and probably exploded on August 23 (16:29) 2011 (Nugent et al 20119. The maximum of the blue-band light curve was reached on JD 2455815.3 or IJD 4270.8, about 18 days after the explosion (Tammann and Reindl 2011).
