Constraints on the dark energy equation of state from the imprint of baryons on the power spectrum of clusters
R. Angulo, C. M. Baugh, C. S. Frenk +3
Acoustic oscillations in the baryon-photon fluid leave a signature in the matter power spectrum. The overall shape of the spectrum and the wavelength of the oscillations depend upo…
J-PLUS DR3: Galaxy-Star-Quasar classification
R. von Marttens, V. Marra, M. Quartin +20
The Javalambre Photometric Local Universe Survey (J-PLUS) is a 12-band photometric survey using the 83-cm JAST telescope. Data Release 3 includes 47.4 million sources. J-PLUS DR3 o…
J-PAS: The Javalambre-Physics of the Accelerated Universe Astrophysical Survey
N. Benitez, R. Dupke, M. Moles +149
The Javalambre-Physics of the Accelerated Universe Astrophysical Survey (J-PAS) is a narrow band, very wide field Cosmological Survey to be carried out from the Javalambre Observat…
The miniJPAS survey: the photometric redshift catalogue
A. Hernán-Caballero, J. Varela, C. López-Sanjuan +30
MiniJPAS is a ~1 deg^2 imaging survey of the AEGIS field in 60 bands, performed to demonstrate the scientific potential of the upcoming JPAS survey. Full coverage of the 3800-9100…
The miniJPAS survey: star-galaxy classification using machine learning
P. O. Baqui, V. Marra, L. Casarini +31
Future astrophysical surveys such as J-PAS will produce very large datasets, which will require the deployment of accurate and efficient Machine Learning (ML) methods. In this work…
Investigating the Diversity of Type Ia Supernova Spectra with the Open-Source Relational Database Kaepora
M. R. Siebert, R. J. Foley, D. O. Jones +10
We present a public, open-source relational database (we name kaepora) containing a sample of 4975 spectra of 777 Type Ia supernovae (SNe Ia). Since we draw from many sources, we s…
Constraining the Baryonic Feedback with Cosmic Shear Using the DES Year-3 Small-Scale Measurements
A. Chen, G. Aricò, D. Huterer +139
We use the small scales of the Dark Energy Survey (DES) Year-3 cosmic shear measurements, which are excluded from the DES Year-3 cosmological analysis, to constrain the baryonic fe…
The detectability of baryonic acoustic oscillations in future galaxy surveys
R. Angulo, C. M. Baugh, C. S. Frenk +1
We assess the detectability of baryonic acoustic oscillations (BAO) in the power spectrum of galaxies using ultra large volume N-body simulations of the hierarchical clustering of…
