The role of supernova remnants for the emergence of pre-biotic chemistry in molecular clouds
Giuliana Cosentino, Izaskun Jiménez-Serra, Laura Colzi +11
There is growing evidence that the Sun might have formed within a nebula impacted by at least one SNR. In this scenario, ejecta and shocks from SNRs may have provided the elements…
Globules and pillars in Cygnus X IV. Velocity-resolved [OI] 63 mu map of a peculiar proplyd-like object
N. Schneider, S. Dannhauer, E. Keilmann +14
We investigated an isolated, globule-shaped object (0.37x0.11 pc), located near the centre of the Cygnus OB2 cluster and named proplyd #7 in optical observations. The source can be…
Dust scattering halo of 4U 1630-47: High resolution X-ray and mm observations constrain source and molecular cloud distances
E. Kalemci, M. DÃaz Trigo, E. Oztaban +8
We re-investigated the distance to the black hole X-ray binary 4U 1630-47 by analyzing its dust scattering halo (DSH) using high-resolution X-ray (Chandra) and millimeter (APEX) ob…
The NuSTAR Local AGN Distribution Survey (NuLANDS) I: Towards a Truly Representative Column Density Distribution in the Local Universe
Peter G. Boorman, Poshak Gandhi, Johannes Buchner +33
Hard X-ray-selected samples of Active Galactic Nuclei (AGN) provide one of the cleanest views of supermassive black hole accretion, but are biased against objects obscured by Compt…
First detection of the [CII] 158 micron line in the intermediate-velocity cloud Draco
N. Schneider, V. Ossenkopf-Okada, E. Keilmann +7
High-latitude intermediate-velocity clouds (IVCs) are part of the Milky Way's HI halo and originate from either a galactic fountain process or extragalactic gas infall. They are pa…
