A New Hope for AGN SED Fitting: X-Ray Spectral Analysis of 12MGS AGN with the C2PO-Torus Model
Carys J. E. Gilbert, Lucia Marchetti, Luigi Barchiesi +8
In this paper, we present the results of comprehensive, broadband X-ray spectral analysis of a subsample of 43 mid-Infrared (IR) selected star-forming active galactic nuclei (AGN).…
Euclid Quick Data Release (Q1) Euclid spectroscopy of quasars. 2. Physical properties from spectral fitting
Euclid Collaboration, J. Calhau, G. Calderone +312
A substantial volume of spectroscopic data has become available with the Euclid Data Release (Q1), which represents a unique opportunity to study quasars (QSOs) in the Euclid Deep…
An ALMA Band 7 survey of SDSS/Herschel quasars in Stripe 82: II. The nature of FIR-bright quasars
Evanthia Hatziminaoglou, Hugo Messias, Duncan Farrah +5
We investigate the star formation properties and ultraviolet (UV)/optical spectral characteristics of 142 far-infrared (FIR)-bright quasars at redshifts 1 < z < 4 to probe supermas…
Unified modelling of broad and narrow optical-UV emission lines from massive black holes: interpreting high-redshift JWST observations
Adele Plat, Michaela Hirschmann, Emma Curtis-Lake +10
JWST is uncovering a large population of active galactic nuclei (AGN) at high redshift, motivating the extension of models calibrated on local sources to a broader range of physica…
The Physical Conditions of Low-Mass Galaxies at z=3.5-7.0 from JWST Spectroscopy: The Behaviour of Spectral Line Ratios with Burstiness
Ryan A. Cooper, Karina I. Caputi, Alessandro Marconi +5
We present a study of the physical conditions of galaxies at redshifts , based on emission-line diagnostics of JWST NIRSpec spectra for 1889 star-forming sources spannin…
A Rapid Evolution in the Observed Mbh/M* Relation at z > 3 Revealed via Spectro-photometric SED-Modeling
Ansh R. Gupta, Anthony Taylor, Emma Curtis-Lake +33
Spectroscopic observations from JWST have uncovered a plethora of active galactic nuclei (AGN) at z > 4 with black hole (BH) mass (Mbh) to stellar mass (M*) ratios significantly ab…
Origins of Extreme Emission-Line Ratios in z > 3 Galaxies: Insights from the Lumen Model
Lucie Scharré, Michaela Hirschmann, Adèle Plat +10
Optical emission-line ratios in star-forming galaxies at -8, such as [OIII]/H and [OIII]/[OII], are strongly offset from those at -2, pointing to more extrem…
One cloud is not enough: extreme conditions bias chemical abundances in high-redshift galaxies
Bianca Moreschini, Francesco Belfiore, Alessandro Marconi +18
Since its launch, JWST has opened an unprecedented opportunity to characterise the ionised ISM of high-redshift galaxies using well-established rest-frame UV/optical diagnostics fr…
Fast, dust-poor outflows in the local candidate dual AGN MCG-03-34-64 observed with VLT/ERIS
I. Lamperti, F. Mannucci, E. Bertola +28
We present VLT/ERIS IFU J-band observations of MCG-03-34-64, a nearby (z = 0.0167) Seyfert galaxy hosting a candidate dual AGN system with a separation of ~100 pc between the nucle…
