Fisher matrix for multiple tracers: the information in the cross-spectra
L. Raul Abramo, Ian L. Tashiro, João V. D. Ferri
We derive general expressions for the multi-tracer Fisher matrix, both assuming that the cross-spectra are constrained by the auto-spectra, and also allowing for independent degree…
Black hole virial masses from single-epoch photometry: the miniJPAS test case
Jonás Chaves-Montero, Silvia Bonoli, Benny Trakhtenbrot +25
Precise measurements of black hole masses are essential to understanding the coevolution of these sources and their host galaxies. We develop a novel approach for computing black h…
The information of attribute uncertainties: what convolutional neural networks can learn about errors in input data
Natália V. N. Rodrigues, L. Raul Abramo, Nina S. Hirata
Errors in measurements are key to weighting the value of data, but are often neglected in Machine Learning (ML). We show how Convolutional Neural Networks (CNNs) are able to learn…
The Effective Field Theory of Large-Scale Structure and Multi-tracer
Thiago Mergulhão, Henrique Rubira, Rodrigo Voivodic +1
We study the performance of the perturbative bias expansion when combined with the multi-tracer technique, and their impact on the extraction of cosmological parameters. We conside…
The miniJPAS survey: Identification and characterization of galaxy populations with the J-PAS photometric system
R. M. González Delgado, L. A. Díaz-García, A. de Amorim +39
J-PAS will soon start imaging 8000 deg2 of the northern sky with its unique set of 56 filters (R 60). Before, we observed 1 deg2 on the AEGIS field with an interim camera wi…
J-PAS: Forecasts for dark matter - dark energy elastic couplings
David Figueruelo, Miguel Aparicio Resco, Florencia A. Teppa Pannia +21
We consider a cosmological model where dark matter and dark energy feature a coupling that only affects their momentum transfer in the corresponding Euler equations. We perform a f…
