Radio–FIR correlation: A probe into cosmic ray propagation in the nearby galaxy IC 342 Open
Resolved studies of the correlation between the radio and far-infrared (FIR) emission from galaxies at different frequencies can unveil the interplay between star formation and the relativistic interstellar medium (ISM). Thanks to the LOFA…

Photometric redshifts for quasars from WISE-PS1-STRM Open
Three-dimensional wide-field galaxy surveys are fundamental for cosmological studies. For higher redshifts (z ≳ 1.0), where galaxies are too faint, quasars still trace the large-scale structure of the Universe. Since available telescope ti…

WISE-PS1-STRM: neural network source classification and photometric redshifts for WISE×PS1 Open
We cross-match between the WISE All-Sky and PS1 3π DR2 source catalogues. The resulting catalogue has 354 590 570 objects, significantly fewer than the parent PS1 catalogue, but its combination of optical and infrared colours facilitate bo…

Evidence for a high-<i>z</i>ISW signal from supervoids in the distribution of eBOSS quasars Open
The late-time integrated Sachs-Wolfe (ISW) imprint of $R\gtrsim 100~h^{-1}\, \mathrm{Mpc}$ superstructures is sourced by evolving large-scale potentials due to a dominant dark energy component in the ΛCDM model. The aspect that makes the I…

A common explanation of the Hubble tension and anomalous cold spots in the CMB Open
The standard cosmological paradigm narrates a reassuring story of a universe currently dominated by an enigmatic dark energy component. Disquietingly, its universal explaining power has recently been challenged by, above all, the ∼4σ tensi…

On the realistic validation of photometric redshifts Open
Two of the main problems encountered in the development and accurate\nvalidation of photometric redshift (photo-z) techniques are the lack of\nspectroscopic coverage in feature space (e.g. colours and magnitudes) and the\nmismatch between …
