Attenuation proxy hidden in surface brightness-colour diagrams. A new strategy for the LSST era Open
Large future sky surveys, such as the LSST, will provide optical photometry for billions of objects. This paper aims to construct a proxy for the far ultraviolet attenuation (AFUVp) from the optical data alone, enabling the rapid estimatio…

A comparative study of the fundamental metallicity relation: the impact of methodology on its observed evolution Open
We used 5487 star-forming galaxies at redshift z~0.63 extracted from the VIPERS and 143774 comparison galaxies in the local Universe from the GSWLC catalog. We employed two families of methods: parametric and non-parametric. In the former …

Decoding the IRX–<i>β</i> dust attenuation relation in star-forming galaxies at intermediate redshift Open
Aims. We aim to understand what drives the IRX– β dust attenuation relation at intermediate redshifts (0.5 < z < 0.8) in star-forming galaxies. We investigate the role of various galaxy properties in shaping this observed relation. Methods…

Influence of star-forming galaxy selection on the galaxy main sequence Open
Aims. This work aims to determine how the galaxy main sequence (MS) changes using seven different commonly used methods to select the star-forming galaxies within VIPERS data over 0.5 ≤ z < 1.2. The form and redshift evolution of the MS wa…

X-ray luminosity-star formation rate scaling relation: Constraints from the eROSITA Final Equatorial Depth Survey (eFEDS) Open
Aims. We present measurements of the relation between X-ray luminosity and star formation activity for a sample of normal galaxies spanning the redshift range between 0 and 0.25. We use data acquired by SRG/eROSITA for the performance and …

SFR estimations from <i>z</i> = 0 to <i>z</i> = 0.9 Open
Context. The star formation rate (SFR) is a key ingredient for studying the formation and evolution of galaxies. Being able to obtain accurate estimations of the SFR, for a wide range of redshifts, is crucial for building and studying gala…

SFR estimations from z=0 to z=0.9 -- A comparison of SFR calibrators for star-forming galaxies Open
Using VIPERS, we estimated a set of SFR based on photometric and spectroscopic data. We used, as estimators, photometric bands from ultraviolet to mid-infrared, and spectral lines. Assuming a reference SFR obtained from the spectral energy…
