CHIME/FRB Catalog 1 Results: Statistical Cross-correlations with Large-scale Structure

Abstract: The CHIME/FRB Project has recently released its first catalog of fast radio bursts (FRBs), containing 492 unique sources. We present results from angular cross-correlations of CHIME/FRB sources with galaxy catalogs. We find a statistically significant (p-value ∼ 10−4, accounting for look-elsewhere factors) cross-correlation between CHIME FRBs and galaxies in the redshift range 0.3 ≲ z ≲ 0.5, in three photometric galaxy surveys: WISE × SCOS, DESI-BGS, and DESI-LRG. The level of cross-correlation is consistent w… Show more

“…99% of these FRBs were found to have the following two characteristic features: peak flux (S ν ) varies in the range 0.1 Jy < S ν < 700 Jy and the pulse width is less than one second [6,9]. As mentioned earlier, R LC of a typical NS is ∼ 10 7 − 10 9 cm and it takes less than one second for the GWs to pass through the entire magnetosphere.…”

“…From the last row of the Table (I), we see that our model predicts the progenitor should be a millisecond pulsar with an effective magnetic field strength of 10 10 G and R LC ∼ 10 7 cm. We can do a similar analysis for all the FRBs in the catalog with a pulse width less than one second [6,9]. Our model predicts that the progenitor should be a NS with an effective magnetic field strength in the range 10 9 − 10 11 G and rotation frequency 1 < ω B < 1000.…”
