The warm ISM in the Sgr A region: mid- J CO, atomic carbon, ionized atomic carbon, and ionized nitrogen line observations with the Herschel/HIFI and NANTEN2/SMART Telescopes

We present Herschel/HIFI sub-mm atomic carbon ([CI] P-3(1) - P-3(0) and [CI] P-3(2) - P-3(1)), ionized carbon ( [CII] P-2(3)/2 - P-2(1)/2), and ionized nitrogen ( [NII] P-3(1) - P-3(0)) line observations obtained in the frame of the Herschel Guaranteed Time HEXGAL (Herschel EXtraGALactic) key program (P. I. Rolf Glisten, MPIfR), and NANTEN2/SMART carbon monoxide (CO (J = 4 - 3)) observations of the warm gas around the Sgr A region. The spectrally resolved emission from all lines, and the corresponding line intensity ratios, show a very complex morphology. The determination of spatial and spectral (anti)correlation with known sources in the Sgr A region such as the Arched Filaments, NTF filaments, the Sickle, Quintuplet cluster, CND clouds, is ongoing work.
