Architecture of the Andromeda: a quantitative analysis of clustering in the inner stellar halo

Autor: Geraint F. Lewis, Prajwal R. Kafle, Sanjib Sharma, Simon P. Driver, Aaron S. G. Robotham

We present a quantitative measurement of the amount of clustering present in the inner $\sim30$ kpc of the stellar halo of the Andromeda galaxy (M31). For this we analyse the angular positions and radial velocities of the carefully selected Planetary

We have imaged the bipolar planetary nebula M2-9 using SOFIA's FORCAST instrument in six wavelength bands between 6.6 and 37.1 $\mu m$. A bright central point source, unresolved with SOFIA's $\sim$ 4${''}$-to-5${''}$ beam, is seen at each wavelength,
