Galaxy: Center

Scientific paper

A shift and add algorithm was used to combine ˜3000 L′(λc=3.8 μm) images of the Galactic center to create a high resolution image of the IRS 16 region. A final spatial resolution of 0.32" was achieved with this technique. This image was used to make new measurements of the relative brightnesses and locations of various point sources in the central parsec, as well as search for an L′ counterpart to the radio source Sgr A*. We found a possible counterpart with an L′ brightness of 12.1±0.4 mag, but cannot conclude with certainty that the object detected is in fact Sgr A* .
