Fast Radio Bursts (FRBs) are millisecond-duration events detected from beyond the Milky Way. FRB emission characteristics favor highly magnetized neutron stars, or magnetars, as the sources, as evidenced by FRB-like bursts from a galactic magnetar, and the star-forming nature of FRB host galaxies. However, the processes that produce FRB sources remain unknown. Although galactic magnetars are often linked to core-collapse supernovae (CCSNe), it's uncertain what determines which supernovae result in magnetars. The galactic environments of FRB sources can be harnessed to probe their progenitors. Here, we present the stellar population properties of 30 FRB host galaxies discovered by the Deep Synoptic Array. Our analysis shows a significant deficit of low-mass FRB hosts compared to the occurrence of star-formation in the universe, implying that FRBs are a biased tracer of star-formation, preferentially selecting massive star-forming galaxies. This bias may be driven by galaxy metallicity, which is positively correlated with stellar mass. Metal-rich environments may favor the formation of magnetar progenitors through stellar mergers, as higher metallicity stars are less compact and more likely to fill their Roche lobes, leading to unstable mass transfer. Although massive stars do not have convective interiors to generate strong magnetic fields by dynamo, merger remnants are thought to have the requisite internal magnetic-field strengths to result in magnetars. The preferential occurrence of FRBs in massive star-forming galaxies suggests that CCSN of merger remnants preferentially forms magnetars.

  1. Testing the Isotropy of the Universe with the CHIME/FRB Catalog I

    astro-ph.HE 2026-07 conditional novelty 6.0 of 10

    A 536-burst CHIME FRB sample shows no statistically significant directional anisotropy, though the test's constraining power is limited.

  2. The role of the galaxy stellar mass function in determining the cosmological distribution of astrophysical transients with applications to fast radio bursts and merging binary black holes

    astro-ph.HE 2025-12 conditional novelty 6.0 of 10

    Using the galaxy stellar mass function weighted by observed FRB host masses lowers the relevant stellar-mass density by ~3x, boosting the implied FRB formation efficiency and biasing standard population-inference results.

  3. Constraining the Faint-End Slope of the FRB Energy Function Using CHIME/FRB Catalog-1 and Local Volume Galaxies

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

    No CHIME/FRB Catalog-1 burst is associated with 495 local volume galaxies, yielding a 95% upper limit gamma < 2.3 on the faint-end slope of the FRB energy function down to ~3e34 erg.

    astro-ph.IM 2026-07 conditional novelty 4.0 of 10

    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.

  7. Fast Radio Bursts as cosmological proxies: estimating the Hubble constant

    astro-ph.CO 2025-02 conditional novelty 4.0 of 10

    Using 97 localized fast radio bursts, this paper estimates the Hubble constant at 65.13 +/- 2.52 km/s/Mpc via maximum likelihood, consistent with Planck but not with SH0ES.
