Galactic survey of ^44^Ti sources with the IBIS telescope onboard INTEGRAL. (2016)

Keywords : nuclear reactions, nucleosynthesis, abundances - ISM supernova remnants - gamma-rays: ISM

Abstract:We report the results of the deepest Galactic plane (|b|<17.5{deg}) survey in the 67.9 and 78.4keV nuclear de-excitation lines of titanium-44 (^44^Ti) performed using the data acquired with the IBIS/ISGRI instrument onboard the INTEGRAL satellite during 12yr of operation. The peak sensitivity of our survey reached an unprecedented level of 4.8x10^-6^ph/cm2/s (3{sigma}) that improves the sensitivity of the survey done by Compton Gamma-Ray Observatory/COMPTEL by a factor of ~5. As a result, constraining upper limits for all sources from the catalogue of Galactic supernova remnants (SNRs; Green, 2014, Cat. VII/272) are derived. These upper limits can be used to estimate the exposure needed to detect ^44^Ti emission from any known SNR using ...(more)

The INTEGRAL observatory (Winkler et al., 2003A&A...411L...1W) has demonstrated a great success in surveying the sky in hard X-rays at energies above 20keV. For the current analysis, we utilized all the publicly available data taken until 2014 October (or spacecraft revolution 1469).
