Improving machine learning-derived photometric redshifts and physical property estimates using unlabelled observations
A. Humphrey, P. A. C. Cunha, A. Paulino-Afonso +5
In the era of huge astronomical surveys, machine learning offers promising solutions for the efficient estimation of galaxy properties. The traditional, `supervised' paradigm for t…
An investigation of the star-forming main sequence considering the nebular continuum emission at low-z
Henrique Miranda, Ciro Pappalardo, Polychronis Papaderos +7
The code FADO is the first publicly available population spectral synthesis tool that treats the contribution from ionised gas to the observed emission self-consistently. We study…
Exploring New Redshift Indicators for Radio-Powerful AGN
Rodrigo Carvajal, Israel Matute, José Afonso +4
Active Galactic Nuclei (AGN) are relevant sources of radiation that might have helped reionising the Universe during its early epochs. The super-massive black holes (SMBHs) they ho…
An ACA 1mm survey of HzRGs in the ELAIS-S1: survey description and first results
Hugo Messias, Evanthia Hatziminaoglou, Pascale Hibon +16
Radio-emitting jets might be one of the main ingredients shaping the evolution of massive galaxies in the Universe since early cosmic times. However, identifying early radio active…
Structural analysis of massive galaxies using HST deep imaging at z < 0.5
Sandra N. dos Reis, Fernando Buitrago, Polychronis Papaderos +11
Taking advantage of HST CANDELS data, we analyze the lowest redshift (z<0.5) massive galaxies in order to disentangle their structural constituents and study possible faint non-axi…
The first Super Massive Black Holes: indications from models for future observations
Stergios Amarantidis, José Afonso, Hugo Messias +12
We present an exploration of the expected detection of the earliest Active Galactic Nuclei (AGN) in the Universe from state-of-art galaxy formation and evolution semi-analytic mode…
