Efficient Analysis Routines for Single and Double Peaked Type 2 AGN Spectra

Matthew Selwood, Giorgio Calderone, Sotiria Fotopoulou +1

Driven by the imminent need to rapidly process and classify millions of AGN spectra drawn from next generation astronomical facilities, we present a spectral fitting routine for Ty…

Detecting neutral hydrogen at z > 3 in large spectroscopic surveys of quasars

Michele Fumagalli, Sotiria Fotopoulou, Laura Thomson

We present a pipeline based on a random forest classifier for the identification of high column-density clouds of neutral hydrogen (i.e. the Lyman limit systems, LLSs) in absorptio…

The survey: XL. Obscuration properties of red AGN in

V. A. Masoura, I. Georgantopoulos, G. Mountrichas +6

The combination of optical and mid-infrared (MIR) photometry has been extensively used to select red active galactic nuclei (AGNs). Our aim is to explore the obscuration properties…

4MOST Consortium Survey 6: Active Galactic Nuclei

A. Merloni, D. A. Alexander, M. Banerji +17

X-ray and mid-infrared emission are signposts of the accretion of matter onto the supermassive black holes that reside at the centres of most galaxies. As a major step towards unde…

The XXL survey XXXV. The role of cluster mass in AGN activity

E. Koulouridis, M. Ricci, P. Giles +15

We present the results of a study of the AGN density in a homogeneous and well-studied sample of 167 bona fide X-ray galaxy clusters () from the XXL Survey. The results…

CPz: Classification-aided photometric-redshift estimation

S. Fotopoulou, S. Paltani

Broadband photometry offers a time and cost effective method to reconstruct the continuum emission of celestial objects. Thus, photometric redshift estimation has supported the sci…
