A case study of hurdle and generalized additive models in astronomy: the escape of ionizing radiation

1 code implementation18 May 2018 M. W. Hattab, R. S. de Souza, B. Ciardi, J. -P. Paardekooper, S. Khochfar, C. Dalla Vecchia

A pivotal aspect to comprehend the EoR is to probe the intertwined relationship between the fraction of ionizing photons capable to escape dark haloes, also known as the escape fraction ($f_{esc}$), and the physical properties of the galaxy.

On the realistic validation of photometric redshifts, or why Teddy will never be Happy

1 code implementation30 Jan 2017 R. Beck, C. -A. Lin, E. E. O. Ishida, F. Gieseke, R. S. de Souza, M. V. Costa-Duarte, M. W. Hattab, A. Krone-Martins

Two of the main problems encountered in the development and accurate validation of photometric redshift (photo-z) techniques are the lack of spectroscopic coverage in feature space (e. g. colours and magnitudes) and the mismatch between photometric error distributions associated with the spectroscopic and photometric samples.
