Compton-thick AGN Characterisation in a Multi-wavelength Context: Insights from the 70-Month \textit{SWIFT}/BAT Catalogue

Muhammad Luqman Hakeem Musa, Zamri Zainal Abidin, Masatoshi Imanishi +2

We analyse Compton-thick active galactic nuclei (CT AGNs), a heavily obscured subclass that challenges traditional X-ray diagnostics. Using 243 sources from the 70-Month \textit{SW…

A Census of Active Galactic Nuclei Identified by the Mid-infrared [Ne v] Line at

S. Yassir, A. Annuar

We present a census of local active galactic nuclei (AGN) at a redshift of selected using the high-ionization [Ne v] m emission line from the Infrared…

X-ray and CO-Derived Column Densities in AGN: A Study of Obscuration Properties in CTAGN and Non-CTAGN

M. L. H. Musa, Z. Z. Abidin, A. Annuar +1

Obscuration in active galactic nuclei (AGN) provides insights into the material surrounding the central engine. Compton-thick AGN (CTAGN), characterized by a column density of $N_{…

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…

The NuSTAR Serendipitous Survey: the 80-month catalog and source properties of the high-energy emitting AGN and quasar population

Claire L. Greenwell, Lizelke Klindt, George B. Lansbury +32

We present a catalog of hard X-ray serendipitous sources detected in the first 80 months of observations by the Nuclear Spectroscopic Telescope Array (NuSTAR). The NuSTAR serendipi…

The stellar system HIP 101227: is it a binary, a triple or a quadruple system?

Zahra Talal Yousef, Adlyka Annuar, Abdallah Mohammad Hussein +4

In this paper, we present the analysis of the stellar system HIP 101227 to determine the actual number of components in the system, and their properties. We use dynamical modeling…
