J-PAS & FLAMINGO: Cosmic voids and void galaxies in the gravitational landscape of photometric surveys

J. A. Mansour, B. McCarthy, L. J. Liivamägi +34

The paper presents a method that uses a quasi‑gravitational potential field to identify dynamically dominant cosmic voids and their galaxies in photometric surveys like J‑PAS, show…

Wide Area VISTA Extragalactic Survey (WAVES): Selection of targets for the Wide survey using decision-tree classification

G. Kaur, M. Bilicki, S. Bellstedt +11

The Wide-Area VISTA Extragalactic Survey (WAVES) on the 4-metre Multi-Object Spectroscopic Telescope (4MOST) includes two flux-limited subsurveys with very high (95\%) completeness…

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…

Modelling the selection of galaxy groups with end to end simulations

R. Seppi, D. Eckert, A. Finoguenov +13

Feedback from supernovae and AGN shapes galaxy formation and evolution, yet its impact remains unclear. Galaxy groups offer a crucial probe, as their binding energy is comparable t…

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…
