INTEGRAL observations of PKS 1127-145 (Sanchez-Fernandez)

Proposal Abstract

The gigahertz peaked spectrum (GPS) and compact steep spectrum radiosource PKS 1127-145 is a young radio-galaxy with a 300 kpc jet wasimaged by Chandra. Chandra obsevations of the source revealed abright, flat ~1.2 power-law spectrum which, if extrapolatedto the IBIS/ISGRI energy range would allow a significant detection ofthe source.In this proposal, we aim to detect the source spectrum above 10 keV. Thedetection of the source spectrum, or even a simple detection could inprinciple discriminate among different scenarios for the production ofhigh-energy emission, which in turn may have some bearing on theevolution of these objects. The source lies in an unexplored region of the INTEGRAL If accepted, other extragalactic targets in the region would benefitas well from the increase in the exposure in this under-exposed regionof the sky.

Observation Strategy (Recommended by TAC)

One observation of 200 ks using the standard 5x5 dithering pattern centered on RA, Dec (J2000.0, in degrees) = 172.529, -14.824 (l,b = 275.281, 43.638 degrees).

Proposal grade: C

Data Rights (Recommended by TAC)

Data rights were granted for PKS 1127-145

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 50, 200, 350, 500 and 650 ksec contour.
