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.…

21-cm fluctuations from primordial magnetic fields
Hector Afonso G. Cruz, Tal Adi, Jordan Flitter +2
The fluid forces associated with primordial magnetic fields (PMFs) generate small-scale fluctuations in the primordial density field, which add to the linear matter…

Modeling the SED of the AGN inside NGC 4395
Hector Afonso G. Cruz, Andy D. Goulding, Jenny E. Greene
We study the broad-band spectral energy distribution (SED) of the prototypical low-mass active galactic nucleus (AGN) in NGC 4395. We jointly model the optical through mid-infrared…
