abstract

Fast Radio Bursts (FRBs) are a powerful and mysterious new class of transient that are luminous enough to be detected at cosmological distances. By associating FRBs to host galaxies, we can measure intrinsic and environmental properties that test FRB origin models, in addition to using them as precise probes of distant cosmic gas. The Deep Synoptic Array (DSA-110) is a radio interferometer built to maximize the rate at which it can simultaneously detect and localize FRBs. Here, we present the first sample of FRBs and host galaxies discovered by the DSA-110. This sample of 11 FRBs is the largest, most uniform sample of localized FRBs to date, as it is selected based on association to host galaxies identified in optical imaging by Pan-STARRS1. These FRBs have not been observed to repeat and their radio properties (dispersion, temporal scattering, energy) are similar to that of the known non-repeating FRB population. Most host galaxies have ongoing star formation, as has been identified before for FRB hosts. Two hosts of the new sample are massive, quiescent galaxies. The distribution of star-formation history across this host-galaxy sample shows that the delay-time distribution is wide, with a powerlaw model that spans from $\sim100$\,Myr to $\gtrsim2$\,Gyr. This requires the existence of one or more progenitor formation channels associated with old stellar populations, such as the binary evolution of compact objects.

    A one-loop EFT power spectrum model for FRB free-electron clustering matches FLAMINGO simulations to k ~ 0.2 h/Mpc, with electron bias b_e ~ 0.92 and near-perfect electron-matter correlation.

  3. Measurement of the Dispersion$\unicode{x2013}$Galaxy Cross-Power Spectrum with the Second CHIME/FRB Catalog

    astro-ph.CO 2025-06 conditional novelty 6.0 of 10

    FRB dispersion and foreground galaxy density are spatially correlated at 5.1 sigma, with a fitted plasma clustering cutoff near 0.9 Mpc, measured from 2,873 CHIME FRBs and about 6 million DESI galaxies.

    astro-ph.HE 2025-02 conditional novelty 6.0 of 10

    A mixed young/old FRB population model tuned to CHIME data reproduces the dispersion measure distribution and approximately the scattering distribution, giving fPSFR = 0.58, log10(E*/erg) = 42.27, and gamma = -1.60.

    Proposes a $150M-class lunar farside radio telescope (LFT3) to survey 0.1–2700 MHz in the RFI-pristine shielded zone before lunar-orbital interference closes the window.

  6. Probing Primordial Black Holes with upcoming Radio Telescopes: a case study for LOFAR2.0, FAST Core Array and BINGO

    astro-ph.CO 2026-04 unverdicted novelty 4.0 of 10

    LOFAR2.0, FAST Core Array and BINGO can constrain the PBH dark matter fraction f_PBH below 0.16-0.39 for masses above 10^{-2} to 10 solar masses via FRB lensing statistics.
