J-PAS & FLAMINGO: Cosmic voids and void galaxies in the gravitational landscape of photometric surveys
J. A. Mansour, B. McCarthy, L. J. Liivamägi +34
Photometric surveys offer a powerful way to map the large-scale structure of the Universe, but their redshift errors complicate the identification of cosmic voids, challenging stud…
J-PLUS: Spectral classification and photometric redshifts for 79 million sources in the fourth data release
A. Hernán-Caballero, H. Vázquez Ramió, C. López-Sanjuan +20
We present spectral classifications and photometric redshifts for 79.2 million sources up to an r-band magnitude of 22 in Data Release 4 of the Javalambre Photometric Local Univers…
OJALÁ: Optimizing J-PAS Astronomy for Large-scale Analysis. A foundation model for the SED of galaxies, QSOs and stars
G. Martínez-Solaeche, R. M. González Delgado, R. García-Benito +37
The advent of large-scale surveys requires efficient ML techniques to exploit the information of massive datasets. We present OJALA, a transformer-based autoregressive foundation m…
Unveiling the small-scale web around galaxies with miniJPAS and DESI
Daniela Galárraga-Espinosa, Guinevere Kauffmann, Silvia Bonoli +23
We present the first statistical observational study detecting filaments in the immediate surroundings of galaxies, i.e. the local web of galaxies. Simulations predict that cold ga…
Brazilian Report on Dark Matter 2024
I. F. M. Albuquerque, J. Alcaniz, A. Alves +51
One of the key scientific objectives for the next decade is to uncover the nature of dark matter (DM). We should continue prioritizing targets such as weakly-interacting massive pa…
The J-PAS survey: The effect of photometric redshift errors on cosmic voids
J. A. Mansour, L. J. Liivamägi, A. Tamm +23
We investigated the impact of photometric redshift errors in the ongoing Javalambre Physics of the Accelerating Universe Astrophysical Survey (J-PAS) on void identification and pro…
The J-PLUS collaboration. Additive versus multiplicative systematics in surveys of the large scale structure of the Universe
C. Hernández-Monteagudo, G. Aricò, J. Chaves-Montero +19
Observational and/or astrophysical systematics modulating the observed number of luminous tracers can constitute a major limitation in the cosmological exploitation of surveys of t…
J-PLUS: Tomographic analysis of galaxy angular density and redshift fluctuations in Data Release 3. Constraints on photo- errors, linear bias, and peculiar velocities
C. Hernández-Monteagudo, A. Balaguera-Antolínez, R. von Marttens +19
The {\it Javalambre Photometric Local Universe Survey} (J-PLUS) is a {\it spectro-photometric} survey covering about 3,000~deg in its third data release (DR3), and containing a…
J-PLUS: Bayesian object classification with a strum of BANNJOS
A. del Pino, C. López-Sanjuan, A. Hernán-Caballero +22
With its 12 optical filters, the Javalambre-Photometric Local Universe Survey (J-PLUS) provides an unprecedented multicolor view of the local Universe. The third data release (DR3)…
The miniJPAS survey: Maximising the photo-z accuracy from multi-survey datasets with probability conflation
A. Hernán-Caballero, M. Akhlaghi, C. López-Sanjuan +35
We present a new method for obtaining photometric redshifts (photo-z) for sources observed by multiple photometric surveys using a combination (conflation) of the redshift probabil…
