    Deep Swift/UVOT Observations of GOODS-N and the Evolution of the Ultraviolet Luminosity Function at 0.2 < z < 1.2 by Alexander Belles, Caryl Gronwall, Michael H. Siegel, Robin Ciardullo, Mat J. Page

    Published 2025-01-01
    “…Using our catalog of detected galaxies, we calculate the UV galaxy number counts as a function of apparent magnitude and compute the UV luminosity function (LF) and its evolution with redshift. From the LF fits in various redshift bins, we calculate the star formation rate density as a function of redshift and find evolution consistent with past works. …”

    A Study on the Line of Sight to Galaxies Detected at Gamma-Ray Energies by Amy Furniss, Josepf N. Amador, Olivier Hervet, Ollie Jackson, David A. Williams

    Published 2025-01-01
    “…The LAT-detected AGN between a redshift of 0.4 and 0.7 show higher voidiness compared to the redshift-matched SDSS QSO populations, with a median p -value of 2.3 × 10 ^−5 (a 4.1 σ deviation). …”

    Predicting the Rate of Fast Radio Bursts in Globular Clusters from Binary Black Hole Observations by Aryamann Rao, Claire S. Ye, Maya Fishbach

    Published 2025-01-01
    “…In the mass-loss scenario, the BWD coalescence rates decrease with increasing redshift, similar to some recent measurements of the FRB rate as a function of redshift. …”

    A comparison of Bayesian and frequentist confidence intervals in the presence of a late Universe degeneracy by Eoin Ó. Colgáin, Saeed Pourojaghi, M. M. Sheikh-Jabbari, Darragh Sherwin

    Published 2025-02-01
    “…Projected 1D posteriors for $$\Lambda $$ Λ CDM cosmological parameters become more non-Gaussian with increasing effective redshift when the model is fitted to redshift-binned data in the late Universe. …”

    Unveiling the Cosmic Chemistry: Revisiting the Mass–Metallicity Relation with JWST/NIRSpec at 4 < z < 10 by Arnab Sarkar, Priyanka Chakraborty, Mark Vogelsberger, Michael McDonald, Paul Torrey, Alex M. Garcia, Gourav Khullar, Gary J. Ferland, William Forman, Scott Wolk, Benjamin Schneider, Mark Bautz, Eric Miller, Catherine Grant, John ZuHone

    Published 2025-01-01
    “…We introduce an empirical mass–metallicity–redshift relation: $12+{\rm{log}}({\rm{O}}/{\rm{H}})=6.29+0.237$ × $\mathrm{log}({M}_{* }/{M}_{\odot })-0.06\times (1+z)$ , which accurately reproduces the observed trends in metallicity with both redshift and stellar mass. …”
