Optimal 1D Ly Forest Power Spectrum Estimation -- III. DESI early data
Naim Göksel Karaçaylı, Paul Martini, Julien Guy +59
The one-dimensional power spectrum of the Ly forest provides important information about cosmological and astrophysical parameters, including constraints on wa…
The Lyman- forest catalog from the Dark Energy Spectroscopic Instrument Early Data Release
César Ramírez-Pérez, Ignasi Pérez-Ràfols, Andreu Font-Ribera +67
We present and validate the catalog of Lyman- forest fluctuations for 3D analyses using the Early Data Release (EDR) from the Dark Energy Spectroscopic Instrument (DESI) survey.…
The Dark Energy Spectroscopic Instrument: One-dimensional power spectrum from first Lyman- forest samples with Fast Fourier Transform
Corentin Ravoux, Marie Lynn Abdul-Karim, Eric Armengaud +63
We present the one-dimensional Lyman- forest power spectrum measurement using the first data provided by the Dark Energy Spectroscopic Instrument (DESI). The data sample compris…
A neural network emulator for the Lyman- 1D flux power spectrum
Laura Cabayol-Garcia, Jonás Chaves-Montero, Andreu Font-Ribera +1
The Lyman- forest offers a unique avenue for studying the distribution of matter in the high redshift universe and extracting precise constraints on the nature of dark matter, n…
Consistent clustering and lensing of SDSS-III BOSS galaxies with an extended abundance matching formalism
Sergio Contreras, Jonás Chaves-Montero, Raul E. Angulo
Several analyses have shown that LCDM-based models cannot jointly describe the clustering (GC) and galaxy-galaxy lensing (GGL) of galaxies in the SDSS-III BOSS survey, which is com…
Active galactic nuclei and gravitational redshifts
N. D. Padilla, S. Carneiro, J. Chaves-Montero +4
Context: Gravitational redshift is a classical effect of Einstein's General Relativity, already measured in stars, quasars and clusters of galaxies. Aims: We here aim to identify t…
The miniJPAS survey quasar selection II: Machine learning classification with photometric measurements and uncertainties
Natália V. N. Rodrigues, L. Raul Abramo, Carolina Queiroz +23
Astrophysical surveys rely heavily on the classification of sources as stars, galaxies or quasars from multi-band photometry. Surveys in narrow-band filters allow for greater discr…
The miniJPAS survey: AGN & host galaxy co-evolution of X-ray selected sources
I. E. López, M. Brusa, S. Bonoli +35
Studies indicate strong evidence of a scaling relation in the local Universe between the supermassive black hole mass ($M_\rm{BH}$) and the stellar mass of their host galaxies ($M_…
