Nebular_AGN: A CIGALE module for fitting active galactic nucleus emission lines
Hao Zhang, Patrice Theule, Veronique Buat +3
Aims. The increasing discovery of high-redshift AGNs in recent years imposes more stringent requirements on spectral analysis tools for deriving the properties of AGNs and their ho…
Impact of stellar population models on the estimated physical properties of galaxies
Bozhidara Stoyanova, Médéric Boquien, Paola Santini +5
Accurate estimates of fundamental physical properties of galaxies, such as star formation rates (SFRs) or stellar masses, are essential for testing and constraining models of galax…
Stardust Galaxies at z>9: A Dust-Origin Transition Behind the Excess of UV-Bright Galaxies
D. Burgarella, V. Buat, A. K. Inoue +9
Recent JWST observations suggest that galaxies at z > 9 may be dominated by low-opacity SNe-produced dust before efficient ISM grain growth is established. This transition in dust…
XRF 241001A/SN 2024aiiq: A faint soft X-ray transient detected by SVOM with a broad-line type Ic supernova revealed by JWST
B. Schneider, M. Brunet, B. P. Gompertz +61
X-ray flashes (XRFs) are a type of gamma-ray burst (GRB) with prompt emission predominantly below 30 keV and have been poorly detected by previous missions. The advent of the SVOM…
Near-infrared emission line diagnostics for AGN from the local Universe to redshift 3
Antonello Calabrò, Laura Pentericci, Anna Feltre +35
Optical rest-frame spectroscopic diagnostics are usually employed to distinguish between star formation and AGN-powered emission. However, this method is biased against dusty sourc…
Ultra High-Redshift or Closer-by, Dust-Obscured Galaxies? Deciphering the Nature of Faint, Previously Missed F200W-Dropouts in CEERS
G. Gandolfi, G. Rodighiero, L. Bisigello +42
The James Webb Space Telescope (JWST) is revolutionizing our understanding of the Universe by unveiling faint, near-infrared dropouts previously beyond our reach, ranging from exce…
