Nebular continuum in high-redshift galaxies with JWST
Henrique Miranda, Ciro Pappalardo, José Afonso +2
Studying the relevance of accounting for both stellar and nebular continuum emission when performing optical spectral fitting has been mainly limited to galaxies in the local Unive…
The Road to Identifying the Earliest Radio-Powerful AGN with the SKA
Jose Afonso, Stergios Amarantidis, Stas Shabala +20
The Epoch of Reionization (EoR) is one of the most pivotal frontiers in modern astrophysics, marking the emergence of the first galaxies, stars, and supermassive black holes (SMBHs…
EMU/GAMA: A statistical perspective on active galactic nuclei diagnostics
J. Prathap, A. M. Hopkins, R. Carvajal +19
While it is well known that galaxies are composites of many emission processes, quantifying the various contributions remains challenging. In this work, we use unsupervised machine…
The Evolutionary Map of the Universe: A new radio atlas for the southern hemisphere sky
A. M. Hopkins, A. Kapinska, J. Marvil +70
We present the Evolutionary Map of the Universe (EMU) survey conducted with the Australian Square Kilometre Array Pathfinder (ASKAP). EMU aims to deliver the touchstone radio atlas…
Unveiling faint X-ray AGN populations in the NewAthena era: Insights from cosmological simulations
Nuno Covas, Israel Matute, Stergios Amarantidis +7
Recent observations expanded our understanding of galaxy formation and evolution, yet key challenges persist in the X-ray regime, crucial for studying Active Galactic Nuclei (AGN).…
Importance of modelling the nebular continuum in galaxy spectra
Henrique Miranda, Ciro Pappalardo, José Afonso +7
The neglect of modelling both stellar and nebular emission significantly affects the derived physical properties of galaxies, particularly those with high star formation rates. Whi…
Exploring the Current Star Formation Rate and Nebula Ratio of Star-Formation Galaxies at z < 0.4 with FADO
Yaosong Yu, Qihang Chen, Liang Jing +2
The star formation rate is a crucial astrophysical tracer for understanding the formation and evolution of galaxies, determining the interaction between interstellar medium propert…
Selection of powerful radio galaxies with machine learning
R. Carvajal, I. Matute, J. Afonso +12
We developed and trained a pipeline of three machine learning (ML) models than can predict which sources are more likely to be an AGN and to be detected in specific radio surveys.…
Towards a census of high-redshift dusty galaxies with : A selection of "500 m-risers"
D. Donevski, V. Buat, F. Boone +6
extragalactic surveys offer a unique opportunity to efficiently select a significant number of rare and massive dusty objects, and thus gain insight into the pr…
