Detection of metal absorption lines in quasar spectra: a neural network approach using U-Net
Elena Sofia Mangola, Francesco Pistis, Michele Fumagalli +7
Current and future large spectroscopic surveys are significantly enhancing the volume and resolution of quasar spectra that are observed, which requires the creation of efficient a…
Extending the Little Red Dot population at intermediate redshift with VIPERS
Krzysztof Lisiecki, Krzysztof Hryniewicz, Francesco Pistis +7
Little red dots (LRDs) are a recently identified population of compact, red sources characterised by a distinctive V-shaped UV-to-optical continuum and broad emission lines. Their…
Forecast for the detectability of patchy hydrogen reionization in WEAVE-QSO measurements of the Lyman- forest power spectrum at redshift
Ke Ma, James S. Bolton, Vid Iršič +9
We present the first detailed forecasts for the detectability of patchy hydrogen reionization in the one-dimensional Ly forest power spectrum to be measured by the WEAVE-QSO sur…
From simulations to observations. Methodology and data release of mock TNG50 galaxies at 0.3 < z < 0.7 for WEAVE-StePS
A. Ikhsanova, L. Costantin, A. Pizzella +17
The new generation of optical spectrographs (i.e., WEAVE, 4MOST, DESI, and WST) offer unprecedented opportunities for statistically studying the star formation histories of galaxie…
Automated quasar continuum estimation using neural networks: a comparative study of deep-learning architectures
Francesco Pistis, Michele Fumagalli, Matteo Fossati +13
Context. Ongoing and upcoming large spectroscopic surveys are drastically increasing the number of observed quasar spectra, requiring the development of fast and accurate automated…
Attenuation proxy hidden in surface brightness-colour diagrams. A new strategy for the LSST era
K. Małek, Junais, A. Pollo +22
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…
A comparative study of the fundamental metallicity relation: the impact of methodology on its observed evolution
F. Pistis, A. Pollo, M. Figueira +10
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 familie…
X-ray luminosity-star formation rate scaling relation: Constraints from the eROSITA Final Equatorial Depth Survey (eFEDS)
G. Riccio, G. Yang, Małek +7
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…
Decoding the IRX-β dust attenuation relation in star-forming galaxies at intermediate redshift
M. Hamed, F. Pistis, M. Figueira +11
We aim to understand what drives the IRX-βdust attenuation relation at intermediate redshift (0.5 < z < 0.8) in star-forming galaxies. We investigate the role of various galaxy pro…
Influence of star-forming galaxy selection on the galaxy main sequence
W. J. Pearson, F. Pistis, M. Figueira +4
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 \…
SFR estimations from z=0 to z=0.9 -- A comparison of SFR calibrators for star-forming galaxies
M. Figueira, A. Pollo, K. Małek +7
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.…
The fundamental metallicity relation from SDSS (z~0) to VIPERS (z~0.7) Data selection or evolution
F. Pistis, A. Pollo, M. Scodeggio +6
Aims. We focus on how to homogenize the comparison between galaxy samples having different characteristics. We check the projections of the fundamental metallicity relation (FMR) a…
