Selection of Compton-thick AGN from a hard photometric sample using XMM-Newton observations
Reham Mostafa, Matteo Guainazzi, Alaa Ibrahim
We present a selection technique to detect Compton-thick (CT) active galactic nuclei (AGNs) in the 3XMM/SDSS-DR7 cross-correlation. A subsample of 3481 X-ray sources that are detec…
Interstellar Hydrocarbons: Degradation Chemistry in Diffuse Clouds
Zainab Awad, Serena Viti
Observations of diffuse clouds showed that they contain a number of simple hydrocarbons (e.g. CH, CH, (l- and c-)CH, and CH) in abundances that may be difficult to…
On the Formation of Deuterated Methyl Formate in Hot Corinos
Zainab Awad, Audrey Coutens, Serena Viti +1
Methyl formate, HCOOCH, and many of its isotopologues have been detected in astrophysical regions with considerable abundances. However, the recipe for the formation of this mo…
Gravitational interaction signatures in isolated galaxy triplet systems: a photometric analysis
Amira A. Tawfeek, Kanak Saha, Kaustubh Vaghmare +7
Galaxy triplets are interesting laboratories where we can study the formation and the evolution of small and large systems of galaxies. This study aims to investigate signs of inte…
IFU spectroscopy of southern PN VI: The extraordinary chemo-dynamics of Hen 2-111
M. A. Dopita, A. Ali, A. I. Karakas +3
In this paper we present integral field spectroscopy of the extraordinary Type I bipolar planetary nebula Hen 2-111. In the lobes we map fast moving knots of material with [N II]$λ…
IFU spectroscopy of Southern Planetary Nebulae IV: A Physical Model for IC 418
M. A. Dopita, A. Ali, R. S. Sutherland +2
We describe high spectral resolution, high dynamic range integral field spectroscopy of IC418 covering the spectral range 3300-8950Å and compare with earlier data. We determine lin…
