Broad view on high energy Galactic background: "Carina arm region" (Krivonos)

Proposal Abstract

This proposal is aimed on obtaining legacy-level observational datasets on the Milky Way Galactic disk. The ultimate goal of the entire project is to have model independent and systematics free measurements of the fluxes in nuclear lines (511 keV annihilation emission, 1.8 MeV Al26 and 1.17 MeV and 1.33 MeV Fe60 lines) and a broad-band spectrum of the Galactic background emission, which at different energies is provided either by cumulative emission of faint Galactic sources or by interaction of low energy cosmic rays with interstellar medium. Wide mapping of the Milky Way during the campaign of Galactic latitude scans also contributes to the legacy of the INTEGRAL observatory, giving the opportunity to study the population of Galactic sources at high latitudes.

Observation Strategy (Recommended by TAC)

Total of 1 Ms consisting of rapid latitude scans across the Galactic plane (l = -78.5), with some minor randomizations in l, (maximum shift of one degree) between b = -23 and +30, using a 2 degree step size, and allowing a 144 deg inclination in certain negative latitudes. Pointing duration is 1961 seconds.

Proposal grade: B

Data Rights (Recommended by TAC)

The TAC granted the data rights for diffuse emission (including lines) in the region.

Exposure Map

The exposure maps are in galactic coordinates using the Aitoff projection and units of seconds, and the colour scale is indicated at the bottom. The green lines provide the 100, 300 and 500 ksec contour.
